3+## pandoc 2.14.0.3 (2021-06-22)
4+
5+ * Text.Pandoc.MediaBag `insertMediaBag`: ensure we get a sane mediaPath
6+ for URLs (#7391). In earlier 2.14.x versions, we'd get
7+ incorrect paths for resources downloaded from URLs when the
8+ media are extracted (including in PDF production).
9+ * Text.Pandoc.Parsing: improve `emailAddress` (#7398).
10+ Previously the parser would accept characters in domains
11+ that are illegal in domains, and this sometimes caused it
12+ to gobble bits of the following text.
13+ * txt2tags reader: modify the email address parser so
14+ it still includes form parameters, even after the change to
15+ `emailAddress` in Text.Pandoc.Parsing.
16+ * Text.Pandoc.Readers.Metadata: Fix regression with comment-only YAML
17+ metadata blocks (#7400).
18+ * reveal.js writer and template: better handling of options. Previously
19+ it was impossible to specify false values for options that default to
20+ true (e.g. `center`); setting the option to false just caused the portion
21+ of the template setting the option to be omitted. Now we prepopulate
22+ all the variables with their default values, including them all
23+ unconditionally and allowing them to be overridden.
24+ * Markdown writer: Fix regression in code blocks with attributes (#7397).
25+ Code blocks with a single class but nonempty attributes
26+ were having attributes drop as a result of #7242.
27+ * LaTeX writer:
28+ + Add strut at end of minipage if it contains line breaks.
29+ Without them, the last line is not as tall as it should be in
30+ some cases.
31+ + Always use a minipage for cells with line breaks, when
32+ width information is available (#7393). Otherwise the way we treat them
33+ can lead to content that overflows a cell.
34+ + Use `\strut` instead of `~` before `\\` in empty line.
35+ * Use lts-18.0 stack resolver.
36+ * Require skylighting 0.10.5.2 (adding support for Swift).
37+ * Require commonmark 0.2.1.
38+ * Rephrase section on unsafe HTML in manual.
39+ * Create SECURITY.md
40+
41+## pandoc 2.14.0.2 (2021-06-13)
42+
43+ * Fix MediaBag regressions (#7345). iIn the 2.14 release `--extract-media`
44+ stopped working as before; there could be mismatches between the
45+ paths in the rendered document and the extracted media.
46+ This patch makes several changes that restore the earlier behavior
47+ (while keeping the same API). The `mediaPath` in 2.14 was always
48+ constructed from the SHA1 hash of the media contents. Now, we
49+ preserve the original path unless it's an absolute path or contains
50+ `..` segments (in that case we use a path based on the SHA1 hash of
51+ the contents).
52+
53+ In Text.Pandoc.MediaBag, `mediaDirectory` and `mediaItems` now use the
54+ `mediaPath`, rather than the mediabag key, for the first component of the
55+ tuple. This makes more sense, I think, and fits with the documentation of
56+ these functions; eventually, though, we should rework the API so that
57+ `mediaItems` returns both the keys and the MediaItems.
58+
59+ In Text.Pandoc.Class.IO, rewriting of source paths in `extractMedia` has
60+ been fixed.
61+
62+ In Text.Pandoc.Class.PandocMonad, `fillMediaBag` has been modified so that
63+ it doesn't modify image paths (that was part of the problem in #7345).
64+
65+ We now do path normalization (e.g. `\` separators on Windows) in
66+ writing the media.
67+
68+ * Text.Pandoc.PDF:
69+
70+ + Text.Pandoc.PDF: Fix regression in 2.14 for generation of PDFs with
71+ SVGs (#7344).
72+ + Only print relevant part of environment on `--verbose`. Since
73+ `--verbose` output might be put in an issue, we want to avoid
74+ spilling out secrets in environment variables.
75+
76+ * Markdown reader: fix pipe table regression in 2.11.4 (#7343).
77+ Previously pipe tables with empty headers (that is, a header
78+ line with all empty cells) would be rendered as headerless
79+ tables. This broke in 2.11.4. The fix here is to produce an
80+ AST with an empty table head when a pipe table has all empty
81+ header cells.
82+
83+ * LaTeX reader: don't allow optional `*` on symbol control sequences
84+ (#7340). Generally we allow optional starred variants of LaTeX commands
85+ (since many allow them, and if we don't accept these explicitly,
86+ ignoring the star usually gives acceptable results). But we
87+ don't want to do this for `\(*\)` and similar cases.
88+
89+ * Docx reader: handle absolute URIs in Relationship Target (#7374).
90+
91+ * Docx writer: fix handling of empty table headers (Albert Krewinkel,
92+ #7369). A table header which does not contain any cells is now treated as
93+ an empty header.
94+
95+ * LaTeX writer: Fix regression in table header position (#7347).
96+ In recent versions the table headers were no longer bottom-aligned
97+ (if more than one line). This patch fixes that by using minipages
98+ for table headers in non-simple tables.
99+
100+ * CommonMark writer:
101+
102+ + Do not use simple class for fenced-divs (Jan Tojnar, amends #7242.)
103+ + Do not throw away attributes when `Ext_attributes` is enabled.
104+ `Ext_attributes` covers at least the following:
105+ `Ext_fenced_code_attributes`, `Ext_header_attributes`,
106+ `Ext_inline_code_attributes`, `Ext_link_attributes`.
107+
108+ * Markdown writer:
109+
110+ + Allow `pipe_tables` to be disabled for commonmark formats
111+ (`commonmark_x`, `gfm`) (#7375).
112+ + Re-use functions from Text.Pandoc.Markdown.Inline (Jan Tojnar).
113+
114+ * DocBook writer: Remove non-existent admonitions (Jan Tojnar).
115+ `attention`, `error` and `hint` are reStructuredText specific.
116+
117+ * HTML writer: Don't omit width attribute on div (#7342).
118+
119+ * Text.Pandoc.MIME, `extensionFromMimeType`: add a few special cases.
120+ When we do a reverse lookup in the MIME table, we just get the
121+ last match, so when the same mime type is associated with several
122+ different extensions, we sometimes got weird results, e.g. `.vs`
123+ for `text/plain`. These special cases help us get the most standard
124+ extensions for mime types like `text/plain`.
125+
126+ * Lua utils: fix handling of table headers in `from_simple_table` (Albert
127+ Krewinkel, #7369). Passing an empty list of header cells now results
128+ in an empty table header.
129+
130+ * Text.Pandoc.Citeproc:
131+
132+ + Avoid duplicate classes and attributes on references div.
133+ + Fix regression in citeproc processing (#7376). If inline
134+ references are used (in the metadata `references` field), we
135+ should still only include in the bibliography items that are
136+ actually cited (unless `nocite` is used).
137+
138+ * Require citeproc 0.4.0.1. This fixes a bug which led to doubled
139+ "et al." in some (rare) circumstances.
140+
141+ * MANUAL.txt:
142+
143+ + Mention GladTeX for EPUB export (Sebastian Humenda).
144+ This updates the manual and the web site about the GladTeX usage.
145+ + More details and a useful link for YAML syntax.
146+
147+ * CONTRIBUTING.md: update modules overview (Albert Krewinkel).
148+
149+ * using-the-pandoc-api.md: switch from String to Text (Albert Krewinkel).
150+
151+
152+## pandoc 2.14.0.1 (2021-06-01)
153+
154+ * Commonmark reader: Fix regression in 2.14 with YAML metdata block parsing,
155+ which could cause the document body to be omitted after metadata (#7339).
156+
157+ * HTML reader: fix column width regression in 2.14 (#7334).
158+ Column widths specified with a style attribute were off by a factor of 100.
159+
160+ * Markdown reader: in `rebasePaths`, check for both Windows and Posix
161+ absolute paths. Previously Windows pandoc was treating
162+ `/foo/bar.jpg` as non-absolute.
163+
164+ * Text.Pandoc.Logging: In rendering `LoadedResource`, use relative paths.
165+
166+ * Docx writer: fix regression on captions (#7328). The "Table Caption"
167+ style was no longer getting applied. (It was overwritten by "Compact.")
168+
169+ * Use commonmark-extensions 0.2.1.2
170+
171+## pandoc 2.14 (2021-05-28)
172+
173+ * Change reader types, allowing better tracking of source positions
174+ [API change]. Previously, when multiple file arguments were provided,
175+ pandoc simply concatenated them and passed the contents to the readers,
176+ which took a Text argument. As a result, the readers had no way of knowing
177+ which file was the source of any particular bit of text. This meant that
178+ we couldn't report accurate source positions on errors or include accurate
179+ source positions as attributes in the AST. More seriously, it meant that
180+ we couldn't resolve resource paths relative to the files containing them
181+ (see e.g. #5501, #6632, #6384, #3752).
182+
183+ * Add `rebase_relative_paths` extension (#3752). When enabled, this
184+ extension rewrites relative image and link paths by prepending
185+ the (relative) directory of the containing file. This
186+ behavior is useful when your input sources are split
187+ into multiple files, across several directories, with files
188+ referring to images stored in the same directory. The
189+ extension can be enabled for all markdown and commonmark-based formats.
190+
191+ * Add Text.Pandoc.Sources (exported module), with a `Sources` type and a
192+ `ToSources` class. A `Sources` wraps a list of `(SourcePos, Text)` pairs
193+ [API change]. A parsec `Stream` instance is provided for `Sources`. The
194+ module also exports versions of parsec's `satisfy` and other Char parsers
195+ that track source positions accurately from a `Sources` stream (or any
196+ instance of the new `UpdateSourcePos` class).
197+
198+ * Text.Pandoc.Parsing
199+
200+ + Export the modified Char parsers defined in Text.Pandoc.Sources
201+ instead of the ones parsec provides. Modified parsers to use a
202+ `Sources` as stream [API change].
203+ + Improve include file functions [API change]. Remove old
204+ `insertIncludedFileF`. Give `insertIncludedFile` a more general type,
205+ allowing it to be used where `insertIncludedFileF` was.
206+ + Add parameter to the `citeKey` parser from
207+ Text.Pandoc.Parsing, which controls whether the `@{..}`
208+ syntax is allowed [API change].
209+
210+ * Text.Pandoc.Error: Modified the constructor `PandocParsecError` to take a
211+ `Sources` rather than a `Text` as first argument, so parse error locations
212+ can be accurately reported.
213+
214+ * Fix source position reporting for YAML bibliographies (#7273).
215+
216+ * Issue error message when reader or writer format is malformed
217+ (#7231). Previously we exited with an error status but (due to a bug)
218+ no message.
219+
220+ * Smarter smart quotes (#7216, #2103). Treat a leading `"` with no
221+ closing `"` as a left curly quote. This supports the practice, in
222+ fiction, of continuing paragraphs quoting the same speaker without an
223+ end quote. It also helps with quotes that break over lines in line blocks.
224+
225+ * Markdown reader:
226+
227+ + Use MetaInlines not MetaBlocks for multimarkdown metadata fields.
228+ This gives better results in converting to e.g. pandoc markdown.
229+ + Implement curly-brace syntax for Markdown citation keys (#6026).
230+ The change provides a way to use citation keys that contain
231+ special characters not usable with the standard citation key syntax.
232+ Example: `@{foo_bar{x}'}` for the key `foo_bar{x}`. It also allows
233+ separating citation keys from immediately following text, e.g. `@{foo}A`.
234+
235+ * RST reader:
236+
237+ + Seek include files in the directory of the file
238+ containing the include directive, as RST requires (#6632).
239+ + Use `insertIncludedFile` from Text.Pandoc.Parsing
240+ instead of reproducing much of its code.
241+
242+ * Org reader: Resolve org includes relative to the directory containing the
243+ file containing the INCLUDE directive (#5501).
244+
245+ * ODT reader: Treat tabs as spaces (#7185, niszet).
246+
247+ * Docx reader:
248+
249+ + Add handling of vml image objects (#7257, mbrackeantidot).
250+ + Support new table features (Emily Bourke, #6316): column
251+ spans, row spans, multiple header rows, table description
252+ (parsed as a simple caption), captions, column widths.
253+
254+ * LaTeX reader:
255+
256+ + Improved siunitx support (#6658, #6620).
257+ + Better support for `\xspace` (#7299).
258+ + Improve parsing of `\def` macros. We previously set "verbatim mode"
259+ even for parsing the initial `\def`; this caused problems
260+ for `\def` nested inside another `\def`.
261+ + Implement `\newif`.
262+
263+ * ConTeXt writer: improve ordered lists (#5016, Denis Maier).
264+ Change ordered list from itemize to enumerate. Add new
265+ itemgroup for ordered lists. Remove manual insertion of
266+ width attributes. Use tabular figures in ordered list
267+ enumerators.
268+
269+ * HTML reader:
270+
271+ + Don't fail on unmatched closing "script" tag (Albert Krenkel, #7282).
272+ + Keep h1 tags as normal headers (#2293, Albert Krewinkel).
273+ The tags `<title>` and `<h1 class="title">` often contain the same
274+ information, so the latter was dropped from the document. However, as
275+ this can lead to loss of information, the heading is now always
276+ retained. Use `--shift-heading-level-by=-1` to turn the `<h1>`
277+ into the document title, or a filter to restore the previous behavior.
278+ + Handle relative lengths (e.g. `2*`) in HTML column widths (#4063).
279+ See <https://www.w3.org/TR/html4/types.html#h-6.6>.
280+
281+ * DocBook/JATS readers:
282+
283+ + Fix mathml regression caused by the switch in XML libraries (#7173).
284+ + Fix "phrase" in DocBook: take classes from "role" not "class" (#7195).
285+
286+ * DocBook reader: ensure that first and last names are separated (#6541).
287+
288+ * Jira reader (Albert Krewinkel, #7218):
289+
290+ + Support "smart" links: `[alias|https://example.com|smart-card]` syntax.
291+ + Allow spaces and most unicode characters in attachment links.
292+ + No longer require a newline character after `{noformat}`.
293+ + Only allow URI path segment characters in bare links.
294+ + The `file:` schema is no longer allowed in bare links; these
295+ rarely make sense.
296+
297+ * Plain writer: handle superscript unicode minus (#7276).
298+
299+ * LaTeX writer:
300+
301+ + Better handling of line breaks in simple tables (#7272).
302+ Now we also handle the case where they're embedded in other elements,
303+ e.g. spans.
304+ + For beamer output, support `exampleblock` and `alertblock` (#7278).
305+ A block will be rendered as an `exampleblock` if the heading
306+ has class `example` and an `alertblock` if it has class `alert`.
307+ + Separate successive quote chars with thin space (#6958,
308+ Albert Krewinkel). Successive quote characters are separated with
309+ a thin space to improve readability and to prevent unwanted ligatures.
310+ Detection of these quotes sometimes had failed if the second quote
311+ was nested in a span element.
312+ + Separate successive quote chars with thin space (#6958, Albert
313+ Krewinkel).
314+
315+ * EPUB Writer: Fix belongs-to-collection XML id choice (#7267, nuew).
316+ The epub writer previously used the same XML id for both the book
317+ identifier and the epub collection. This causes an error on epubcheck.
318+
319+ * BibTeX/BibLaTeX writer: Handle `annote` field (#7266).
320+
321+ * ZimWiki writer: allow links and emphasis in headers (#6605,
322+ Albert Krewinkel).
323+
324+ * ConTeXt writer:
325+
326+ + Support blank lines in line blocks (#6564, Albert Krewinkel,
327+ thanks to @denismaier).
328+ + Use span identifiers as reference anchors (#7246, Albert Krewinkel).
329+
330+ * HTML writer:
331+
332+ + Keep attributes from code nested below `pre` tag (#7221,
333+ Albert Krewinkel). If a code block is defined with `<pre><code
334+ class="language-x">…</code></pre>`, where the `<pre>` element has no
335+ attributes, then the attributes from the `<code>` element are used
336+ instead. Any leading `language-` prefix is dropped in the code's
337+ `class` attribute are dropped to improve syntax highlighting.
338+ + Ensure headings only have valid attribs in HTML4 (#5944, Albert
339+ Krewinkel).
340+ + Parse `<header>` as a Div (Albert Krewinkel).
341+
342+ * Org writer:
343+
344+ + Inline latex envs need newlines (#7252, tecosaur).
345+ As specified in https://orgmode.org/manual/LaTeX-fragments.html, an
346+ inline \begin{}...\end{} LaTeX block must start on a new line.
347+ + Use LaTeX style maths deliminators (#7196, tecosaur).
348+
349+ * JATS writer (Albert Krewinkel):
350+
351+ + Use either styled-content or named-content for spans (#7211).
352+ If the element has a content-type attribute, or at least one class,
353+ then that value is used as `content-type` and the span is put inside
354+ a `<named-content>` element. Otherwise a `<styled-content>` element
355+ is used instead.
356+ + Reduce unnecessary use of `<p>` elements for wrapping (#7227).
357+ The `<p>` element is used for wrapping in cases were the contents
358+ would otherwise not be allowed in a certain context. Unnecessary
359+ wrapping is avoided, especially around quotes (`<disp-quote>` elements).
360+ + Convert spans to `<named-content>` elements (#7211). Spans with
361+ attributes are converted to `<named-content>` elements instead of
362+ being wrapped with `<milestone-start/>` and `<milestone-end>`
363+ elements. Milestone elements are not allowed in documents using the
364+ articleauthoring tag set, so this change ensures the creation of valid
365+ documents.
366+ + Add footnote number as label in backmatter (#7210). Footnotes in the
367+ backmatter are given the footnote's number as a label. The
368+ articleauthoring output is unaffected from this change, as footnotes
369+ are placed inline there.
370+ + Escape disallows chars in identifiers. XML identifiers must start
371+ with an underscore or letter, and can contain only a limited set
372+ of punctuation characters. Any IDs not adhering to these rules are
373+ rewritten by writing the offending characters as `Uxxxx`,
374+ where `xxxx` is the character's hex code.
375+
376+ * Jira writer: use `{color}` when span has a color attribute
377+ (Albert Krewinkel, tarleb/jira-wiki-markup#10).
378+
379+ * Docx writer:
380+
381+ + Autoset table width if no column has an explicit width (Albert
382+ Krewinkel).
383+ + Extract Table handling into separate module (Albert Krewinkel).
384+ + Support colspans and rowspans in tables (Albert Krewinkel, #6315).
385+ + Support multirow table headers (Albert Krewinkel).
386+ + Improve integration of settings from reference.docx (#1209).
387+ This change allows users to create a reference.docx that
388+ sets `w:proofState` for spelling or grammar to `dirty`,
389+ so that spell/grammar checking will be triggered on the
390+ generated docx.
391+ + Copy over more settings from reference.docx (#7240). From settings.xml
392+ in the reference-doc, we now include: `zoom`, `embedSystemFonts`,
393+ `doNotTrackMoves`, `defaultTabStop`, `drawingGridHorizontalSpacing`,
394+ `drawingGridVerticalSpacing`, `displayHorizontalDrawingGridEvery`,
395+ `displayVerticalDrawingGridEvery`, `characterSpacingControl`,
396+ `savePreviewPicture`, `mathPr`, `themeFontLang`, `decimalSymbol`,
397+ `listSeparator`, `autoHyphenation`, `compat`.
398+ + Set zoom to 100% by default in settings.xml.
399+ + Align math options more with current Word defaults (e.g. Cambria Math
400+ font).
401+ + Remove `rsid`s from default settings.xml. Word will add these
402+ when revisions are made.
403+
404+ * Ms writer: Handle tables with multiple paragraphs (#7288).
405+ Previously they overflowed the table cell width. We now set line lengths
406+ per-cell and restore them after the table has been written.
407+
408+ * Markdown writer:
409+
410+ + Use cleaner braceless syntax for code blocks with a
411+ single class (#7242, Jan Tojnar).
412+ + Add quotes properly in markdown YAML metadata fields (#7245).
413+ This fixes a bug, which caused the writer to look at the *last*
414+ rather than the *first* character in determining whether quotes
415+ were needed. So we got spurious quotes in some cases and
416+ didn't get necessary quotes in others.
417+ + Use `@{..}` syntax for citations when needed.
418+ + Use fewer unneeded escapes for `#` (see #6259).
419+ + Improve escaping of `@`. We need to escape literal `@` before
420+ `{` because of the new citation syntax.
421+
422+ * Commonmark writer: Use backslash escapes for `<` and `|`...
423+ instead of entities (#7208).
424+
425+ * Powerpoint writer: allow `monofont` to be specified in metadata
426+ (#7187).
427+
428+ * LaTeX template:
429+
430+ + Use non-starred names for xcolor color names (#6109).
431+ This should make svgnames and x11names work properly.
432+ + Fix bad vertical spacing after bibliography (#7234, badumont).
433+ + List of figures before list of tables (#7235, Julien Dutant).
434+ + Move CSL macro definitions before header-includes so they can be
435+ overridden (#7286).
436+ + Improve treatment of CSL `entry-spacing` (#7296).
437+ Previously with the default template settings (`indent` variable
438+ not set), we would get interparagraph spaces separating bib
439+ entries even with `entry-spacing="0"`. On the other hand,
440+ setting `entry-spacing="2"` gave ridiculously large spacing.
441+ This change makes the spacing caused by `entry-spacing` a multiple
442+ of `\parskip` by default, which gives aesthetically reasonable
443+ output. Those who want a larger or smaller unit (e.g. because
444+ they use `indent` which sets `\parskip` to 0) may
445+ `\setlength{\cslentryspacingunit}{10pt}` in header-includes
446+ to override the defaults.
447+ + Move title, author, date up to top of preamble (#7295).
448+ This allows header-includes to use them, and puts them
449+ in a position where you can see them immediately.
450+ + Define commands for zero width non-joiner character
451+ (#6639, Albert Krewinkel). The zero-width non-joiner character
452+ is used to avoid ligatures (e.g. in German).
453+
454+ * ConTeXt template:
455+
456+ + Define `enumerate` itemgroup (#5016, Denis Maier).
457+ + List of figures before list of tables (#7235, Julien Dutant).
458+
459+ * reveal.js template:
460+
461+ + Support `toc-title` (#7171, Florian Kohrt).
462+ + Use `hash: true` by default rather than `history: true` (#6968).
463+
464+ * HTML-based slide shows: add support for `institute` (#7289, Thomas
465+ Hodgson).
466+
467+ * Text.Pandoc.Extensions: Add constructor `Ext_rebase_relative_paths` to
468+ `Extensions` [API change].
469+
470+ * Text.Pandoc.XML.Light: add Eq, Ord instances for Content,
471+ Element, Attr, CDataKind [API change].
472+
473+ * Text.Pandoc.MediaBag:
474+
475+ + Change type to use a `Text` key instead of `[FilePath]`.
476+ We normalize the path and use `/` separators for consistency.
477+ + Export `MediaItem` type [API change].
478+ + Change `MediaBag` type to a map from Text to MediaItem [API change].
479+ + `lookupMedia` now returns a `MediaItem` [API change].
480+ + Change `insertMedia` so it sets the `mediaPath` to a filename based on
481+ the SHA1 hash of the contents. This will be used when contents
482+ are extracted.
483+
484+ * Text.Pandoc.Class.PandocMonad:
485+
486+ + Remove `fetchMediaResource` [API change]. Use `fetchItem` to get
487+ resources in `fillMediaBag`.
488+ + Add informational message in `downloadOrRead` indicating what path
489+ local resources have been loaded from.
490+
491+ * Text.Pandoc.Logging:
492+
493+ + Remove single quotes around paths in messages.
494+ + Add LoadedResource constructor to LogMessage [API change].
495+ This is for INFO-level messages telling where image data has been
496+ loaded from. (This can vary because of the resource path.)
497+
498+ * Text.Pandoc.Asciify: simplify code and export `toAsciiText` [API change].
499+ Instead of encoding a giant (and incomplete) map, we now
500+ just use unicode-transforms to normalize the text to
501+ a canonical decomposition, and manipulate the result.
502+
503+ * App: allow tabs expansion even if file-scope is used (Albert Krewinkel,
504+ #6709). Tabs in plain-text inputs are now handled correctly, even if
505+ the `--file-scope` flag is used.
506+
507+ * Add new internal module Text.Pandoc.Writers.GridTable (Albert Krewinkel).
508+
509+ * Text.Pandoc.Highlighting: Change type of `languagesByExtension`, adding
510+ a parameter for a `SyntaxMap` [API change] (Jan Tojnar, #7241).
511+ Languages defined using `--syntax-definition` were not recognized by
512+ `languagesByExtension`. This patch corrects that, allowing the writers
513+ to see all custom definitions. The LaTeX writer still uses the default
514+ syntax map, but that's okay in that context, since
515+ `--syntax-definition` won't create new listings styles.
516+
517+ * Text.Pandoc.Citeproc:
518+
519+ + Ensure that CSL-related attributes are passed on to a Div with id
520+ 'refs'. Otherwise things like `entry-spacing` won't work when
521+ such Divs are used.
522+ + Use metadata's `lang` for the lang parameter of citeproc, overriding
523+ `localeLanguage`.
524+ + Recognize locators spelled with a capital letter (#7323).
525+ + Add a comma and a space in front of the suffix if it doesn't start
526+ with space or punctuation (#7324).
527+ + Don't detect math elements as locators (#7321).
528+
529+ * Remove Text.Pandoc.BCP47 module [API change]. Use types and functions
530+ from UnicodeCollation.Lang instead. This is a richer implementation
531+ of BCP 47.
532+
533+ * Text.Pandoc.Shared:
534+
535+ + Fix regression in grid tables for wide characters (#7214).
536+ In the translation from String to Text, a char-width-sensitive
537+ `splitAt'` was dropped. This commit reinstates it and uses it to make
538+ `splitTextByInstances` char-width sensitive.
539+ + Add `getLang` (formerly in the now-removed BCP47) [API change].
540+
541+ * Text.Pandoc.SelfContained: use `application/octet-stream`
542+ for unknown mime types instead of halting with an error (#7202).
543+
544+ * Lua filters: respect Inlines/Blocks filter functions in `pandoc.walk_*`
545+ (Albert Krewinkel).
546+
547+ * Add text as build-depend for trypandoc (#7193, Roman Beránek).
548+
549+ * Bump upper-bounds for network-uri, time, attoparsec.
550+
551+ * Use citeproc 0.4.
552+
553+ * Use texmath 0.12.3.
554+
555+ * Use jira-wiki-markup 1.3.5 (Albert Krewinkel).
556+
557+ * Require latest skylighting (fixes a bug in XML syntax highlighting).
558+
559+ * Use latest xml-conduit.
560+
561+ * Use latest commonmark, commonmark-extensions, commonmark-pandoc.
562+
563+ * Use haddock-library-1.10.0 (Albert Krewinkel).
564+
565+ * Allow compilation with base 4.15 (Albert Krewinkel).
566+
567+ * MANUAL:
568+
569+ + Add information about `lang` and bibliography sorting.
570+ + Add info about YAML escape sequences, link to spec (#7152,
571+ Albert Krewinkel).
572+ + Note that `institute` variable works for HTML-based slides.
573+ + Update documentation on citation syntax.
574+ + Add citation example for locators and suffixes (Tristan Stenner)
575+
576+ * Updated and fixed typos in documentation (Charanjit Singh,
577+ Anti-Distinctlyminty, Tatiana Porras, obcat).
578+
579+ * Add instructions for installing pandoc-types before compiling filter.
580+
581+ * INSTALL: add note that parallel installations should be avoided
582+ (#6865).
583+
584+ * Remove `biblatex-nussbaum.md` test. It is basically the same
585+ as `biblaetx-quotes.md`.
586+
587+ * Command tests: fail if a file contains no tests---and fix a
588+ test that failed in that way!
589+
590+ * Use smaller images in tests, reducing the size of the source tarball by 8 MB.
591+
592+
593+## pandoc 2.13 (2021-03-21)
594+
595+ * Support `yaml_metadata_block` extension for `commonmark`, `gfm` (#6537).
596+ This supported is a bit more limited than with pandoc's
597+ `markdown`. The YAML block must be the first thing in the input,
598+ and the leaf notes are parsed in isolation from the rest of
599+ the document. So, for example, you can't use reference
600+ links if the references are defined later in the document.
601+
602+ * Fix fallback to default partials when custom templates are used.
603+ If the directory containing a template does not contain the partial,
604+ it should be sought in the default templates, but this was not
605+ working properly (#7164).
606+
607+ * Handle `nocite` better with `--biblatex` and `--natbib` (#4585).
608+ Previously the nocite metadata field was ignored with these formats.
609+ Now it populates a `nocite-ids` template variable and causes a
610+ `\nocite` command to be issued.
611+
612+ * Text.Pandoc.Citeproc: apply `fixLinks` correctly (#7130). This is code
613+ that incorporates a prefix like `https://doi.org/` into a following link
614+ when appropriate.
615+
616+ * Text.Pandoc.Shared:
617+
618+ + Remove `backslashEscapes`, `escapeStringUsing` [API change]. Replace
619+ these inefficient association list lookups with more efficient escaping
620+ functions in the writers that used them (for a 10-25% performance boost
621+ in org, haddock, rtf, texinfo writers).
622+ + Remove `ToString`, `ToText` typeclasses [API change]. These were needed
623+ for the transition from String to Text, but they are no longer used and
624+ may clash with other things.
625+ + Simplify `compactDL`.
626+
627+ * Text.Pandoc.Parsing:
628+
629+ + Change type of `readWithM` so that it is no longer polymorphic
630+ [API change]. The `ToText` class has been removed, and now that we've
631+ completed the transition to Text we no longer need this to operate
632+ on Strings.
633+ + Remove `F` type synonym [API change]. Muse and Org were defining their
634+ own `F` anyway.
635+
636+ * Text.Pandoc.Readers.Metadata:
637+
638+ + Export `yamlMetaBlock` [API change].
639+ + Make `yamlBsToMeta`, `yamlBsToRefs` polymorphic on the parser state
640+ [API change].
641+
642+ * Markdown reader: Fix regression with `tex_math_backslash` (#7155).
643+
644+ * MediaWiki reader: Allow block-level content in notes (ref) (#7145).
645+
646+ * Jira reader (Albert Krewinkel):
647+
648+ + Fixed parsing of autolinks (i.e., of bare URLs in the text).
649+ Previously an autolink would take up the rest of a line, as spaces
650+ were allowed characters in these items.
651+ + Emoji character sequences no longer cause parsing failures. This was
652+ due to missing backtracking when emoji parsing fails.
653+ + Mark divs created from panels with class "panel".
654+
655+ * RST reader: fix logic for ending comments (#7134). Previously comments
656+ sometimes got extended too far.
657+
658+ * DocBook writer: include Header attributes as XML attributes on
659+ section (Erik Rask). Attributes with key names that are not allowed
660+ as XML attributes are dropped, as are attributes with invalid values
661+ and `xml:id` (DocBook 5) and `id` (DocBook 4).
662+
663+ * Docx writer:
664+
665+ + Make `nsid` in `abstractNum` deterministic. Previously we assigned
666+ a random number, but we don't need random values, so now we just
667+ assign a value based on the list marker.
668+ + Use integral values for `w:tblW` (#7141).
669+
670+ * Jira writer (Albert Krewinkel):
671+
672+ + Block quotes are only rendered as `bq.` if they do not contain a
673+ linebreak.
674+ + Jira writer: improve div/panel handling. Include div attributes in
675+ panels, always render divs with class `panel` as panels, and
676+ avoid nesting of panels.
677+
678+ * HTML writer: Add warnings on duplicate attribute values.
679+ This prevents emitting invalid HTML. Ultimately it would be good to
680+ prevent this in the types themselves, but this is better for now.
681+
682+ * Org writer: Prevent unintended creation of ordered list items (#7132,
683+ Albert Krewinkel). Adjust line wrapping if default wrapping would cause
684+ a line to be read as an ordered list item.
685+
686+ * JATS templates: support 'equal-contrib' attrib for authors (Albert
687+ Krewinkel). Authors who contributed equally to a paper may be marked
688+ with `equal-contrib`.
689+
690+ * reveal.js template: replace JS comment with HTML (#7154, Florian Kohrt).
691+
692+ * Text.Pandoc.Logging: Add `DuplicateAttribute` constructor to `LogMessage`.
693+ [API change]
694+
695+ * Use `-j4` for linux release build. This speeds up the build dramatically
696+ on arm.
697+
698+ * cabal.project: remove ghcoptions. Move flags to top level, so they can
699+ be set differently on the command line.
700+
701+ * Require latest texmath, skylighting, citeproc, jira-wiki-markup.
702+ (The latest skylighting fixes a bad bug with Haskell syntax highlighting.)
703+ Narrow version bounds for texmath, skylighting, and citeproc, since
704+ the test output depend on them.
705+
706+ * Use doclayout 0.3.0.2. This significantly reduces the time and memory
707+ needed to compile pandoc.
708+
709+ * Use `foldl'` instead of `foldl` everywhere.
710+
711+ * Update bounds for random (#7156, Alexey Kuleshevich).
712+
713+ * Remove uses of some partial functions.
714+
715+ * Don't bake in a larger stack size for the executable.
716+
717+ * Test improvements:
718+
719+ + Use `getExecutablePath` from base, avoiding the dependency on
720+ `executable-path`.
721+ + Factor out `setupEnvironment` in Helpers, to avoid code duplication.
722+ + Fix finding of data files by setting teh `pandoc_datadir` environment
723+ variable when we shell out to pandoc. This avoids the need to use
724+ `--data-dir` for the tests, which caused problems finding `pandoc.lua`
725+ when compiling without the `embed_data_files` flag (#7163).
726+
727+ * Benchmark improvements:
728+
729+ + Build `+RTS -A8m -RTS` into default ghc-options for benchmark.
730+ This is necessary to get accurate benchmark results; otherwise we
731+ are largely measuring garbage collecting, some not related to the
732+ current benchmark.
733+ + Allow specifying BASELINE file in 'make bench' for comparison
734+ (otherwise the latest benchmark is chosen by default).
735+ + Force `readFile` in benchmarks early (Bodigrim).
736+
737+ * CONTRIBUTING: suggest using a `cabal.project.local` file (#7153,
738+ Albert Krewinkel).
739+
740+ * Add ghcid-test to Makefile. This loads the test suite in ghcid.
741+
742+
743+## pandoc 2.12 (2021-03-08)
744+
745+ * `--resource-path` now accumulates if specified multiple
746+ times (#6152). Resource paths specified later on the command line are
747+ prepended to those specified earlier. Thus,
748+ `--resource-path foo --resource-path bar:baz` is equivalent to
749+ `--resource-path bar:bas:foo`. (The previous behavior was
750+ for the last `--resource-path` to replace all the rest.)
751+ `resource-path` in defaults files behaves the same way: it
752+ will be prepended to the resource path set by earlier
753+ command line options or defaults files. This change
754+ facilitates the use of multiple defaults files: each can
755+ specify a directory containing resources it refers to
756+ without clobbering the resource paths set by the others.
757+
758+ * Allow defaults files to refer to the home directory, the
759+ user data directory, and the directory containing the defaults file
760+ itself (#5871, #5982, #5977). In fields that expect file paths
761+ (and only in these fields),
762+
763+ + `${VARIABLE}` will expand to the value of the environment variable
764+ `VARIABLE` (and in particular `${HOME}` will expand to the path
765+ of the home directory). A warning will be raised for undefined
766+ variables.
767+ + `${USERDATA}` will expand to the path of the user data
768+ directory in force when the defaults file is being processed.
769+ + `${.}` will expand to the directory containing the defaults file.
770+ (This allows default files to be placed in a directory containing
771+ resources they make use of.)
772+
773+ * When downloading content from URL arguments, be sensitive to
774+ the character encoding (#5600). We can properly handle UTF-8 and latin1
775+ (ISO-8859-1); for others we raise an error. Fall back to latin1 if
776+ no charset is given in the mime type and UTF-8 decoding fails.
777+
778+ * Allow abbreviations that don't end in a period to be
779+ specified using `--abbreviations` (#7124).
780+
781+ * Add new unexported module Text.Pandoc.XML.Light, as well
782+ as Text.Pandoc.XML.Light.Types, Text.Pantoc.XML.Light.Proc,
783+ Text.Pandoc.XML.Light.Output. (Closes #6001, #6565, #7091).
784+
785+ This module exports definitions of `Element` and `Content`
786+ that are isomorphic to xml-light's, but with Text
787+ instead of String. This allows us to keep most of the code in existing
788+ readers that use xml-light, but avoid lots of unnecessary allocation.
789+
790+ We also add versions of the functions from xml-light's
791+ Text.XML.Light.Output and Text.XML.Light.Proc that operate on our
792+ modified XML types, and functions that convert xml-light types to our
793+ types (since some of our dependencies, like texmath, use xml-light).
794+
795+ We export functions that use xml-conduit's parser to produce an
796+ `Element` or `[Content]`. This allows existing pandoc code to use
797+ a better parser without much modification.
798+
799+ The new parser is used in all places where xml-light's parser was
800+ previously used. Benchmarks show a significant performance improvement
801+ in parsing XML-based formats (with docbook, opml, jats, and docx
802+ almost twice as fast, odt and fb2 more than twice as fast).
803+
804+ In addition, the new parser gives us better error reporting than
805+ xml-light. We report XML errors, when possible, using the new
806+ `PandocXMLError` constructor in `PandocError`.
807+
808+ These changes revealed the need for some changes in the tests. The
809+ docbook-reader.docbook test lacked definitions for the entities it used;
810+ these have been added. And the docx golden tests have been updated,
811+ because the new parser does not preserve the order of attributes.
812+
813+ * DocBook reader:
814+
815+ + Avoid expensive tree normalization step, as it is not necessary
816+ with the new XML parser.
817+ + Support `informalfigure` (#7079) (Nils Carlson).
818+
819+ * Docx reader:
820+
821+ + Use Map instead of list for Namespaces. This gives a speedup of
822+ about 5-10%. With this and the XML parsing changes, the docx reader
823+ is now about twice as fast as in the previous release.
824+
825+ * HTML reader:
826+
827+ + Small performance tweaks.
828+ + Also, remove exported class `NamedTag(..)` [API change]. This was just
829+ intended to smooth over the transition from String to Text and is no
830+ longer needed.
831+ + As a result, the functions `isInlineTag` and `isBlockTag`
832+ are no longer polymorphic; they apply to a `Tag Text` [API change].
833+ + Do a lookahead to find the right parser to use. This takes
834+ benchmarks from 34ms to 23ms, with less allocation.
835+ + Fix bad handling of empty `src` attribute in `iframe` (#7099).
836+ If `src` is empty, we simply skip the `iframe`.
837+ If `src` is invalid or cannot be fetched, we issue a warning
838+ nd skip instead of failing with an error.
839+
840+ * JATS reader:
841+
842+ + Avoid tree normalization, which is no longer necessary given the
843+ new XML parser.
844+
845+ * LaTeX reader:
846+
847+ + Don't export `tokenize`, `untokenize` [API change]. These are internal
848+ implementation details, which were only exported for testing.
849+ They don't belong in the public API.
850+ + Improved efficiency of the parser. With these changes the reader
851+ is almost twice as fast as in the last release in our benchmarks.
852+ + Code cleanup, removing some unnecessary things.
853+ + Rewrite `withRaw` so it doesn't rely on fragile assumptions
854+ about token positions (which break when macros are expanded)
855+ (#7092). This requires the addition of `sEnableWithRaw` and
856+ `sRawTokens` in `LaTeXState`, and a new combinator `disablingWithRaw`
857+ to disable collecting of raw tokens in certain contexts.
858+ Add `parseFromToks` to Text.Pandoc.Readers.LaTeX.Parsing.
859+ Fix parsing of single character tokens so it doesn't mess
860+ up the new raw token collecting. These changes slightly increase
861+ allocations and have a small performance impact.
862+ + Handle some bibtex/biblatex-specific commands that used to be
863+ dealt with in pandoc-citeproc (#7049).
864+ + Optimize `satisfyTok`, avoiding unnecessary macro expansion steps.
865+ Benchmarks after this change show 2/3 of the run time and 2/3 of the
866+ allocation of the Feb. 10 benchmarks.
867+ + Removed `sExpanded` in state. This isn't actually needed and checking
868+ it doesn't change anything.
869+ + Improve `braced'`. Remove the parameter, have it parse the
870+ opening brace, and make it more efficient.
871+ + Factor out pieces of the LaTeX reader to make the module smaller.
872+ This reduces memory demands when compiling. Created
873+ Text.Pandoc.Readers.{LaTeX,Math,Citation,Table,Macro,Inline}.
874+ Changed Text.Pandoc.Readers.LaTeX.SIunitx to export a command map
875+ instead of individual commands.
876+ + Handle table cells containing `&` in `\verb` (#7129).
877+
878+ * Make Text.Pandoc.Readers.LaTeX.Types an unexported module [API change].
879+
880+ * Markdown reader:
881+
882+ + Improved handling of mmd link attributes in references (#7080).
883+ Previously they only worked for links that had titles.
884+ + Improved efficiency of the parser (benchmarks show a 15% speedup).
885+
886+ * OPML reader:
887+
888+ + Avoid tree normalization, which is no longer necessary with the
889+ new XML parser.
890+
891+ * ODT reader:
892+
893+ + Finer-grained errors on parse failure (#7091).
894+ + Give more information if the zip container can't be unpacked.
895+
896+ * Org reader:
897+
898+ + Support `task_lists` extension (Albert Krewinkel, #6336).
899+ + Fix bug in org-ref citation parsing (Albert Krewinkel, #7101).
900+ The org-ref syntax allows to list multiple citations separated by
901+ comma. Previously commas were accepted as part of the citation id,
902+ so all citation lists were parsed as one single citation.
903+
904+ * RST reader:
905+
906+ + Use `getTimestamp` instead of `getCurrentTime` to fetch timestamp.
907+ Setting `SOURCE_DATE_EPOCH` will allow reproducible builds.
908+ + RST reader: fix handling of header in CSV tables (#7064).
909+ The interpretation of this line is not affected by the delim option.
910+
911+ * Jira reader:
912+
913+ + Modified the Doc parser to skip leading blank lines. This fixes
914+ parsing of documents which start with multiple blank lines (Albert
915+ Krewinkel, #7095).
916+ + Prevent URLs within link aliases to be treated as autolinks (Albert
917+ Krewinkel, #6944).
918+
919+ * Text.Pandoc.Shared
920+
921+ + Remove formerly exported functions that are no longer used in the
922+ code base: `splitByIndices`, `splitStringByIndicies`, `substitute`,
923+ and `underlineSpan` (which had been deprecated in April 2020)
924+ [API change].
925+ + Export `handleTaskListItem` (Albert Krewinkel) [API change].
926+ + Change `defaultUserDataDirs` to `defaultUserDataDir` [API
927+ change]. We determine what is the default user data directory
928+ by seeing whether the XDG directory and/or legacy
929+ directory exist.
930+
931+ * BibTeX writer:
932+
933+ + BibTeX writer: use doclayout and doctemplate. This change allows
934+ bibtex/biblatex output to wrap as other formats do,
935+ depending on the settings of `--wrap` and `--columns` (#7068).
936+
937+ * CSL JSON writer:
938+
939+ + Output `[]` if no references in input, instead of raising a
940+ PandocAppError as before.
941+
942+ * Docx writer:
943+
944+ + Use `getTimestamp` instead of `getCurrentTime` for timestamp.
945+ Setting `SOURCE_DATE_EPOCH` will allow reproducible builds.
946+
947+ * EPUB writer:
948+
949+ + Use `getTimestamp` instead of `getCurrentTime` for timestamp.
950+ Setting `SOURCE_DATE_EPOCH` will allow reproducible builds (#7093).
951+ This does not suffice to fully enable reproducible in EPUB, since
952+ a unique id is still being generated for each build.
953+ + Support `belongs-to-collection` metadata (#7063) (Nick Berendsen).
954+
955+ * JATS writer:
956+
957+ + Escape special chars in reference elements (Albert Krewinkel).
958+ Prevents the generation of invalid markup if a citation element
959+ contains an ampersand or another character with a special meaning
960+ in XML.
961+
962+ * Jira writer:
963+
964+ + Use Span identifiers as anchors (Albert Krewinkel).
965+ + Use `{noformat}` instead of `{code}` for unknown languages (Albert
966+ Krewinkel). Code blocks which are not marked as a language supported
967+ by Jira are rendered as preformatted text via `{noformat}` blocks.
968+
969+ * LaTeX writer:
970+
971+ + Adjust hypertargets to beginnings of paragraphs (#7078).
972+ Use `\vadjust pre` so that the hypertarget takes you to the beginning
973+ of the paragraph rather than one line down.
974+ This makes a particular difference for links to citations using
975+ `--citeproc` and `link-citations: true`.
976+ + Change BCP47 lang tag from `jp` to `ja` (Mauro Bieg, #7047).
977+ + Use function instead of map for accent lookup (should be
978+ more efficient).
979+ + Split the module to make it easier to compile on low-memory
980+ systems: added Text.Pandoc.Writers.LaTeX.{Util,Citation,Lang}.
981+
982+ * Markdown writer:
983+
984+ + Handle math right before digit. We insert an HTML comment to
985+ avoid a `$` right before a digit, which pandoc will not recognize
986+ as a math delimiter.
987+ + Split the module to make it easier to compile on low-memory
988+ systems: added Text.Pandoc.Writers.Markdown.{Types,Inline}.
989+
990+ * ODT writer:
991+
992+ + Use `getTimestamp` instead of `getCurrentTime` for timestamp.
993+ Setting `SOURCE_DATE_EPOCH` will allow reproducible builds.
994+ + Update default ODT style (Lorenzo). Previously, the "First paragraph"
995+ style inherited from "Standard" but not from "Text body." Now
996+ it is adjusted to inherit from "Text body", to avoid some ugly
997+ spacing issues. It may be necessary to update a custom `reference.odt`
998+ in light of this change.
999+
1000+ * Org writer:
1001+
1002+ + Support `task_lists` extension (Albert Krewinkel, #6336).
1003+
1004+ * Pptx writer:
1005+
1006+ + Use `getTimestamp` instead of `getCurrentTime` for timestamp.
1007+ Setting `SOURCE_DATE_EPOCH` will allow reproducible builds.
1008+
1009+ * JATS templates: tag `author.name` as `string-name` (Albert Krewinkel).
1010+ The partitioning the components of a name into surname, given names,
1011+ etc. is not always possible or not available. Using `author.name`
1012+ allows to give the full name as a fallback to be used when
1013+ `author.surname` is not available.
1014+
1015+ * Add default templates for bibtex and biblatex, so that
1016+ the variables `header-include`, `include-before`, `include-after`
1017+ (or alternatively the command line options
1018+ `--include-in-header`, `--include-before-body`, `--include-after-body`)
1019+ may be used.
1020+
1021+ * LaTeX template:
1022+
1023+ + Update to iftex package (#7073) (Andrew Dunning)
1024+ + Wrap url colours in braces (#7121) (Loïc Grobol).
1025+
1026+ * revealjs template: Add 'center' option for vertical slide centering.
1027+ (maurerle, #7104).
1028+
1029+ * Text.Pandoc.XML: Improve efficiency of `fromEntities`.
1030+
1031+ * Text.Pandoc.MIME
1032+
1033+ + Add exported function `getCharset` [API change].
1034+
1035+ * Text.Pandoc.UTF8: change IO functions to return Text, not String
1036+ [API change]. This affects `readFile`, `getContents`, `writeFileWith`,
1037+ `writeFile`, `putStrWith`, `putStr`, `putStrLnWith`, `putStrLn`.
1038+ `hPutStrWith`, `hPutStr`, `hPutStrLnWith`, `hPutStrLn`, `hGetContents`.
1039+ This avoids the need to uselessly create a linked list of characters
1040+ when emiting output.
1041+
1042+ * Text.Pandoc.App
1043+
1044+ + Add `parseOptionsFromArgs` [API change, new exported function].
1045+ + Add fields for CSL options to `Opt` [API change]:
1046+ `optCSL`, `optbibliography`, `optCitationAbbreviations`.
1047+
1048+ * Text.Pandoc.Citeproc.BibTeX
1049+
1050+ + `Text.Pandoc.Citeproc.writeBibTeXString` now returns
1051+ `Doc Text` instead of `Text` (#7068).
1052+ + Correctly handle `pages` (= `page` in CSL) (#7067).
1053+ + Correctly handle BibLaTeX `langid` (= `language` in CSL, #7067).
1054+ + In BibTeX output, protect foreign titles since there's no language
1055+ field (#7067).
1056+ + Clean up BibTeX parsing (#7049). Previously there was a messy code
1057+ path that gave strange results in some cases, not passing through raw
1058+ tex but trying to extract a string content. This was an artefact of
1059+ trying to handle some special bibtex-specific commands in the BibTeX
1060+ reader. Now we just handle these in the LaTeX reader and simplify
1061+ parsing in the BibTeX reader. This does mean that more raw tex will
1062+ be passed through (and currently this is not sensitive to the
1063+ `raw_tex` extension; this should be fixed).
1064+
1065+ * Text.Pandoc.Citeproc.MetaValue
1066+
1067+ + Correctly parse "raw" date value in markdown references metadata.
1068+ (See jgm/citeproc#53.)
1069+
1070+ * Text.Pandoc.Citeproc
1071+
1072+ + Use https URLs for links (Salim B, #7122).
1073+
1074+ * Text.Pandoc.Class
1075+
1076+ + Add `getTimestamp` [API change]. This attempts to read the
1077+ `SOURCE_DATE_EPOCH` environment variable and parse a UTC time
1078+ from it (treating it as a unix date stamp, see
1079+ https://reproducible-builds.org/specs/source-date-epoch/). If the
1080+ variable is not set or can't be parsed as a unix date stamp, then the
1081+ function returns the current date.
1082+
1083+ * Text.Pandoc.Error
1084+
1085+ + Add `PandocUnsupportedCharsetError` constructor for
1086+ `PandocError` [API change].
1087+ + Export `renderError` [API change].
1088+ + Refactor `handleError` to use `renderError`. This allows us render
1089+ error messages without exiting.
1090+
1091+ * Text.Pandoc.Extensions
1092+
1093+ + `Ext_task_lists` is now supported by org (and turned
1094+ on by default) (Albert Krewinkel, #6336).
1095+ + Remove `Ext_fenced_code_attributes` from allowed commonmark attributes
1096+ (#7097). This attribute was listed as allowed, but it didn't actually
1097+ do anything. Use `attributes` for code attributes and more.
1098+
1099+ * Lua subsystem:
1100+
1101+ + Always load built-in Lua scripts from default data-dir (Albert
1102+ Krewinkel). The Lua modules `pandoc` and `pandoc.List` are now always
1103+ loaded from the system's default data directory. Loading from a
1104+ different directory by overriding the default path, e.g. via
1105+ `--data-dir`, is no longer supported to avoid unexpected behavior
1106+ and to address security concerns.
1107+ + Add module "pandoc.path" (Albert Krewinkel, #6001, #6565).
1108+ The module allows to work with file paths in a convenient and
1109+ platform-independent manner.
1110+ + Use strict evaluation when retrieving AST value from the stack
1111+ (Albert Krewinkel, #6674).
1112+
1113+ * Text.Pandoc.PDF
1114+
1115+ + Disable `smart` extension when building PDF via LaTeX.
1116+ This is to prevent accidental creation of ligatures like
1117+ `` ?` `` and `` !` `` (especially in languages with quotations like
1118+ German), and similar ligature issues. (See jgm/citeproc#54.)
1119+
1120+ * Text.Pandoc.CSV:
1121+
1122+ + Fix parsing of unquoted values (#7112). Previously we didn't allow
1123+ unescaped quotes in unquoted values, but they are allowed
1124+ in CSV.
1125+
1126+ * Test suite:
1127+
1128+ + Use a more robust method for testing the executable. Many
1129+ of our tests require running the pandoc executable. This
1130+ is problematic for a few different reasons. First,
1131+ cabal-install will sometimes run the test suite after
1132+ building the library but before building the executable,
1133+ which means the executable isn't in place for the tests.
1134+ One can work around that by first building, then building
1135+ and running the tests, but that's fragile. Second, we
1136+ have to find the executable. So far, we've done that using
1137+ a function `findPandoc` that attempts to locate it
1138+ relative to the test executable (which can be located
1139+ using findExecutablePath). But the logic here is delicate
1140+ and work with every combination of options. To solve both
1141+ problems, we add an `--emulate` option to the
1142+ `test-pandoc` executable. When `--emulate` occurs as the
1143+ first argument passed to `test-pandoc`, the program simply
1144+ emulates the regular pandoc executable, using the rest of
1145+ the arguments (after `--emulate`). Thus, `test-pandoc
1146+ --emulate -f markdown -t latex` is just like `pandoc -f
1147+ markdown -t latex`. Since all the work is done by library
1148+ functions, implementing this emulation just takes a couple
1149+ lines of code and should be entirely reliable. With this
1150+ change, we can test the pandoc executable by running the
1151+ test program itself (locatable using `findExecutablePath`)
1152+ with the `--emulate` option. This removes the need for the
1153+ fragile `findPandoc` step, and it means we can run our
1154+ integration tests even when we're just building the
1155+ library, not the executable. [Note: part of this change
1156+ involved simplifying some complex handling to set
1157+ environment variables for dynamic library paths. I have
1158+ tested a build with `--enable-dynamic-executable`, and it
1159+ works, but further testing may be needed.]
1160+ + Print accurate location if a test fails (Albert
1161+ Krewinkel). Ensures that tasty-hunit reports the location
1162+ of the failing test instead of the location of the helper
1163+ `test` function.
1164+
1165+ * Documentation: Update URLs and use `https` where possible (#7122,
1166+ Salim B).
1167+
1168+ * Add `doc/libraries.md`, a description of libraries that support pandoc.
1169+
1170+ * MANUAL.txt
1171+
1172+ + MANUAL: block-level formatting is not allowed in line blocks (#7107).
1173+ + Clarify `tex_math_dollars` extension. Note that no blank lines
1174+ are allowed between the delimiters in display math.
1175+ + Add MANUAL section on reproducible builds.
1176+ + Document no template fallback for absolute path (#7077, Nixon
1177+ Enraght-Moony.)
1178+ + Improve docs for cite-method.
1179+ + Update README and man page.
1180+
1181+ * Makefile: in `make bench`, create CSV files for comparison and compare
1182+ against previous benchmark run. Add timestamp to CSV filenames.
1183+
1184+ * cabal.project: don't explicitly set -trypandoc.
1185+ If we do, this can't be overridden on the cabal command line.
1186+
1187+ * doc/lua-filters.md: improve documentation for
1188+ `pandoc.mediabag.insert`, `pandoc.mediabag.fetch`,
1189+ `directory`, `normalize` (Albert Krewinkel).
1190+
1191+ * Allow base64-bytestring-1.2.* (Dmitrii Kovanikov)
1192+
1193+ * Require jira-wiki-markup 1.3.3 (Albert Krewinkel)
1194+
1195+ * Require citeproc 0.3.0.8, which correctly titlecases when titles
1196+ contain non-ASCII characters.
1197+
1198+ * Use skylighting 0.10.4. This version of skylighting uses xml-conduit
1199+ rather than hxt. This speeds up parsing of XML syntax definitions
1200+ fourfold, and removes four packages from pandoc's dependency graph:
1201+ hxt-charproperties, hxt-unicode, hxt-regex-xmlschema, hxt.
1202+
1203+ * Add script `tools/parseTimings.pl` to help pin down which
1204+ modules take the most time and memory to compile.
1205+
1206+ * Avoid unnecessary use of NoImplicitPrelude pragma (#7089) (Albert
1207+ Krewinkel)
1208+
1209+ * Benchmarks
1210+
1211+ + Use the lighter-weight tasty-bench instead of criterion.
1212+ + Run writer benchmarks for binary formats too.
1213+ + Alphabetize benchmarks.
1214+ + Don't run benchmarks for bibliography formats
1215+ (yet; we need a special input for them).
1216+ + Show allocation data
1217+ + Clean up benchmark code.
1218+ + Allow specifying patterns using `-p blah'.
1219+
1220+ * trypandoc: add 2 second timeout.
1221+
1222+ * Use `-split-sections` in creating linux release binary.
1223+ This reduces executable size significantly (by about 30%).
1224+
1225+ * Remove `weigh-pandoc`. It's not really useful any more, now that our
1226+ regular benchmarks include data on allocation.
1227+
1228+ * Improve linux package build process and add script to
1229+ automate building an arm64 binary package.
1230+
1231+
1232+## pandoc 2.11.4 (2021-01-22)
1233+
1234+ * Add `biblatex`, `bibtex` as output formats (closes #7040).
1235+
1236+ * Recognize more extensions as markdown by default (#7034):
1237+ `mkdn`, `mkd`, `mdwn`, `mdown`, `Rmd`.
1238+
1239+ * Implement defaults file inheritance (#6924, David Martschenko).
1240+ Allow defaults files to inherit options from other defaults files by
1241+ specifying them with the following syntax:
1242+ `defaults: [list of defaults files or single defaults file]`.
1243+
1244+ * Fix infinite HTTP requests when writing epubs from URL source (#7013).
1245+ Due to a bug in code added to avoid overwriting the cover image
1246+ if it had the form `fileX.YYY`, pandoc made an endless sequence
1247+ of HTTP requests when writing epub with input from a URL.
1248+
1249+ * Org reader:
1250+
1251+ + Allow multiple pipe chars in todo sequences (Albert Krewinkel, #7014).
1252+ Additional pipe chars, used to separate "action" state from "no further
1253+ action" states, are ignored. E.g., for the following sequence, both
1254+ `DONE` and `FINISHED` are states with no further action required:
1255+ `#+TODO: UNFINISHED | DONE | FINISHED`.
1256+ + Restructure output of captioned code blocks (Albert Krewinkel, #6977).
1257+ The Div wrapper of code blocks with captions now has the class
1258+ "captioned-content". The caption itself is added as a Plain block
1259+ inside a Div of class "caption". This makes it easier to write filters
1260+ which match on captioned code blocks. Existing filters will need to be
1261+ updated.
1262+ + Mark verbatim code with class `verbatim` (Dimitri Sabadie, #6998).
1263+
1264+ * LaTeX reader:
1265+
1266+ + Handle `filecontents` environment (#7003).
1267+ + Put contents of unknown environments in a Div when `raw_tex` is not
1268+ enabled (#6997). (When `raw_tex` is enabled, the whole environment is
1269+ parsed as a raw block.) The class name is the name of the environment.
1270+ Previously, we just included the contents without the surrounding Div,
1271+ but having a record of the environment's boundaries and name can be
1272+ useful.
1273+
1274+ * Mediawiki reader:
1275+
1276+ + Allow space around storng/emph delimiters (#6993).
1277+
1278+ * New module Text.Pandoc.Writers.BibTeX, exporting
1279+ writeBibTeX and writeBibLaTeX. [API change]
1280+
1281+ * LaTeX writer:
1282+
1283+ + Revert table line height increase in 2.11.3 (#6996).
1284+ In 2.11.3 we started adding `\addlinespace`, which produced less dense
1285+ tables. This wasn't an intentional change; I misunderstood a comment in
1286+ the discussion leading up to the change. This commit restores the earlier
1287+ default table appearance. Note that if you want a less dense table, you
1288+ can use something like `\def\arraystretch{1.5}` in your header.
1289+
1290+ * EPUB writer:
1291+
1292+ + Adjust internal links to identifiers defined in raw HTML sections
1293+ after splitting into chapters (#7000).
1294+ + Recognize `Format "html4"`, `Format "html5"` as raw HTML.
1295+ + Adjust internal links to images, links, and tables after splitting into
1296+ chapters. Previously we only did this for Div and Span and Header
1297+ elements (see #7000).
1298+
1299+ * Ms writer:
1300+
1301+ + Don't justify text inside table cells.
1302+
1303+ * JATS writer:
1304+
1305+ + Use `<element-citation>` if `element_citations`
1306+ extension is enabled (Albert Krewinkel).
1307+ + Fix citations (Albert Krewinkel, #7018). By default
1308+ we use formatted citations.
1309+ + Ensure that `<disp-quote>` is always wrapped in `<p>` (#7041).
1310+
1311+ * Markdown writer:
1312+
1313+ + Cleaned up raw formats. We now react appropriately
1314+ to `gfm`, `commonmark`, and `commonmark_x` as raw formats.
1315+
1316+ * RST writer:
1317+
1318+ + Fix bug with dropped content from inside spans with a class in
1319+ some cases (#7039).
1320+
1321+ * Docx writer:
1322+
1323+ + Handle table header using styles (#7008). Instead of hard-coding
1324+ the border and header cell vertical alignment, we now let this
1325+ be determined by the Table style, making use of Word's
1326+ "conditional formatting" for the table's first row. For
1327+ headerless tables, we use the tblLook element to tell Word
1328+ not to apply conditional first-row formatting.
1329+
1330+ * Commonmark writer:
1331+
1332+ + Implement start number on ordered lists (#7009). Previously they always
1333+ started at 1, but according to the spec the start number is respected.
1334+
1335+ * HTML writer:
1336+
1337+ + Fix implicit_figure at end of footnotes (#7006).
1338+
1339+ * ConTeXt template: Remove `\setupthinrules` from default template.
1340+ The width parameter this used is not actually supported,
1341+ and the command didn't do anything.
1342+
1343+ * Text.Pandoc.Extensions:
1344+
1345+ + Add `Ext_element_citations` constructor (Albert Krewinkel).
1346+
1347+ * Text.Pandoc.Citeproc.BibTeX: New unexported function
1348+ `writeBibtexString`.
1349+
1350+ * Text.Pandoc.Citeproc:
1351+
1352+ + Use finer grained imports (Albert Krewinkel).
1353+ + Factor out and export `getStyle` [API change].
1354+ + Export `getReferences` [API change, #7106].
1355+ + Factor out getLang.
1356+
1357+ * Text.Pandoc.Parsing: modify `gridTableWith'` for headerless tables.
1358+ If the table lacks a header, the header row should be an empty
1359+ list. Previously we got a list of empty cells, which caused
1360+ an empty header to be emitted instead of no header. In LaTeX/PDF
1361+ output that meant we got a double top line with space between.
1362+
1363+ * ImageSize: use `viewBox` for SVG if no length, width attributes (#7045).
1364+ This change allows pandoc to extract size information from more SVGs.
1365+
1366+ * Add simple default.nix.
1367+
1368+ * Use commonmark 0.1.1.3.
1369+
1370+ * Use citeproc 0.3.0.5.
1371+
1372+ * Update default CSL to use latest chicago-author-date.csl.
1373+
1374+ * CONTRIBUTING.md: add note on GNU xargs.
1375+
1376+ * MANUAL.txt:
1377+
1378+ + Update description of `-L`/`--lua-filter`.
1379+ + Document use of citations in note styles (#6828).
1380+
1381+## pandoc 2.11.3.2 (2020-12-29)
1382+
1383+ * HTML reader: use renderTags' from Text.Pandoc.Shared (Albert Krewinkel).
1384+ A side effect of this change is that empty `<col>` elements are written
1385+ as self-closing tags in raw HTML blocks.
1386+
1387+ * Asciidoc writer: Add support for writing nested tables (#6972, timo-a).
1388+ Asciidoc supports one level of nesting. If deeper tables are to be
1389+ written, they are omitted and a warning is issued.
1390+
1391+ * Docx writer: fix nested tables with captions (#6983).
1392+ Previously we got unreadable content, because docx seems
1393+ to want a `<w:p>` element (even an empty one) at the end of
1394+ every table cell.
1395+
1396+ * Powerpoint writer: allow arbitrary OOXML in raw inline elements
1397+ (Albert Krewinkel). The raw text is now included verbatim in the
1398+ output. Previously is was parsed into XML elements, which prevented
1399+ the inclusion of partial XML snippets.
1400+
1401+ * LaTeX writer: support colspans and rowspans in tables (#6950,
1402+ Albert Krewinkel). Note that the multirow package is needed for
1403+ rowspans. It is included in the latex template under a variable,
1404+ so that it won't be used unless needed for a table.
1405+
1406+ * HTML writer: don't include p tags in CSL bibliography entries
1407+ (#6966). Fixes a regression in 2.11.3.
1408+
1409+ * Add `meta-description` variable to HTML templates (#6982). This
1410+ is populated by the writer by stringifying the `description`
1411+ field of metadata (Jerry Sky). The `description` meta tag will
1412+ make the generated HTML documents more complete and SEO-friendly.
1413+
1414+ * Citeproc: fix handling of empty URL variables (`DOI`, etc.).
1415+ The `linkifyVariables` function was changing these to links
1416+ which then got treated as non-empty by citeproc, leading
1417+ to wrong results (e.g. ignoring nonempty URL when empty DOI is present).
1418+ See jgm/citeproc#41.
1419+
1420+ * Use citeproc 0.3.0.3. Fixes an issue in author-only citations when
1421+ both an author and translator are present, and an issue with
1422+ citation group delimiters.
1423+
1424+ * Require texmath 0.12.1. This improves siunitx support in math,
1425+ fixes bugs with `\*mod` family operators and arrays, and avoids
1426+ italicizing symbols and operator names in docx output.
1427+
1428+ * Ensure that the perl interpreter used for filters with `.pl`
1429+ extension (wuffi).
1430+
1431+ * MANUAL: note that textarea content is never parsed as Markdown
1432+ (Albert Krewinkel).

1435+## pandoc 2.11.3.1 (2020-12-18)
1436+
1437+ * Added some missing files to extra-source-files and data
1438+ files, so they are included in the sdist tarball. Closes #6961.
1439+ Cleaned up some extraneous data and test files, and added
1440+ a CI check to ensure that the test and data files included
1441+ in the sdist match what is in the git repository.
1442+
1443+ * Use citeproc 0.3.0.1, which avoids removing nonbreaking
1444+ space at the end of the `initialize-with` attribute. (Some
1445+ journals require nonbreaking space after initials, and this
1446+ makes that possible.)
1447+
1448+## pandoc 2.11.3 (2020-12-17)
1449+
1450+ * With `--bibliography` (or `bibliography` in metadata), a
1451+ URL may now be provided, and pandoc will fetch the resource.
1452+ In addition, if a file path is provided and it is not
1453+ found relative to the working directory, the resource
1454+ path will be searched (#6940).
1455+
1456+ * Add `sourcepos` extension for `commonmark`, `gfm`, `commonmark_x`
1457+ (#4565). With the `sourcepos` extension set set, `data-pos`
1458+ attributes are added to the AST by the commonmark reader. No other
1459+ readers are affected. The `data-pos` attributes are put on elements
1460+ that accept attributes; for other elements, an enlosing Div or Span
1461+ is added to hold the attributes.
1462+
1463+ * Change extensions for `commonmark_x`: replace `auto_identifiers`
1464+ with `gfm_auto_identifiers` (#6863). `commonmark_x` never actually
1465+ supported `auto_identifiers` (it didn't do anything), because the
1466+ underlying library implements gfm-style identifiers only. Attempts
1467+ to add the `auto_identifiers` extension to `commonmark` will now
1468+ fail with an error.
1469+
1470+ * HTML reader:
1471+
1472+ + Split module into several submodules (Albert Krewinkel). Reducing
1473+ module size should reduce memory use during compilation.
1474+ + Support advanced table features (Albert Krewinkel):
1475+ block level content in captions, row and colspans,
1476+ body headers, row head columns, footers, attributes.
1477+ + Disable round-trip testing for tables. Information for cell
1478+ alignment in a column is not preserved during round-trips (Albert
1479+ Krewinkel).
1480+ + Allow finer grained options for tag omission (Albert Krewinkel).
1481+ + Simplify list attribute handling (Albert Krewinkel).
1482+ + Pay attention to `lang` attributes on body element (#6938).
1483+ These (as well as `lang` attributes on the html element) should update
1484+ lang in metadata.
1485+ + Retain attribute prefixes and avoid duplicates (#6938).
1486+ Previously we stripped attribute prefixes, reading `xml:lang` as
1487+ `lang` for example. This resulted in two duplicate `lang`
1488+ attributes when `xml:lang` and `lang` were both used. This commit
1489+ causes the prefixes to be retained, and also avoids invald
1490+ duplicate attributes.
1491+
1492+ * Commonmark reader:
1493+
1494+ + Refactor `specFor`.
1495+ + Set input name to `""` to avoid clutter in sourcepos output.
1496+
1497+ * Org reader:
1498+
1499+ + Parse `#+LANGUAGE` into `lang` metadata field (#6845, Albert
1500+ Krewinkel).
1501+ + Preserve targets of spurious links (#6916, Albert
1502+ Krewinkel). Links with (internal) targets that the reader doesn't
1503+ know about are converted into emphasized text. Information on the
1504+ link target is now preserved by wrapping the text in a Span of class
1505+ `spurious-link`, with an attribute `target` set to the link's
1506+ original target. This allows to recover and fix broken or unknown
1507+ links with filters.
1508+
1509+ * DocBook reader:
1510+
1511+ + Table text width support (#6791, Nils Carlson).
1512+ Table width in relation to text width is not natively supported
1513+ by docbook but is by the docbook `fo` stylesheets through an XML
1514+ processing instruction, `<?dbfo table-width="50%"?>`.
1515+
1516+ * LaTeX reader:
1517+
1518+ + Improve parsing of command options (#6869, #6873).
1519+ In cases where we run into trouble parsing inlines til the
1520+ closing `]`, e.g. quotes, we return a plain string with the
1521+ option contents. Previously we mistakenly included the brackets
1522+ in this string.
1523+ + Preserve center environment (#6852, Igor Pashev).
1524+ The contents of the `center` environment are put in a `Div`
1525+ with class `center`.
1526+ + Don't parse `\rule` with width 0 as horizontal rule. These are
1527+ sometimes used as spacers in LaTeX.
1528+ + Don't apply theorem default styling to a figure inside (#6925).
1529+ If we put an image in italics, then when rendering to Markdown
1530+ we no longer get an implicit figure.
1531+
1532+ * Dokuwiki reader:
1533+
1534+ + Handle unknown interwiki links better (#6932).
1535+ DokuWiki lets the user define his own Interwiki links. Previously
1536+ pandoc reacted to these by emitting a google search link, which is
1537+ not helpful. Instead, we now just emit the full URL including the
1538+ wikilink prefix, e.g. `faquk>FAQ-mathml`. This at least gives users
1539+ the ability to modify the links using filters.
1540+
1541+ * Markdown writer:
1542+
1543+ + Properly handle boolean values in writing YAML metadata (#6388).
1544+ + Ensure that a new csl-block begins on a new line (#6921).
1545+ This just looks better and doesn't affect the semantics.
1546+
1547+ * RST writer:
1548+
1549+ + Better image handling (#6948). An image alone in its paragraph
1550+ (but not a figure) is now rendered as an independent image, with an
1551+ `alt` attribute if a description is supplied. An inline image that
1552+ is not alone in its paragraph will be rendered, as before, using a
1553+ substitution. Such an image cannot have a "center", "left", or
1554+ "right" alignment, so the classes `align-center`, `align-left`, or
1555+ `align-right` are ignored. However, `align-top`, `align-middle`,
1556+ `align-bottom` will generate a corresponding `align` attribute.
1557+
1558+ * Docx writer:
1559+
1560+ + Keep raw openxml strings verbatim (#6933, Albert Krewinkel).
1561+ + Use Content instead of Element. This allows us to inject
1562+ raw OpenXML into the document without reparsing it into an
1563+ Element, which is necessary if you want to inject an open
1564+ tag or close tag.
1565+ + Fix bullets/lists indentation, so that the first level is slightly
1566+ indented to the right instead of right on the margin (cholonam).
1567+ + Support bold and italic in "complex script" (#6911).
1568+ Previously bold and italics didn't work properly in LTR
1569+ text. This commit causes the w:bCs and w:iCs attributes
1570+ to be used, in addition to w:b and w:i, for bold and
1571+ italics respectively.
1572+
1573+ * ICML writer:
1574+
1575+ + Fix image bounding box for custom widths/heighta (Mauro Bieg, #6936).
1576+
1577+ * LaTeX writer:
1578+
1579+ + Improve table spacing (#6842, #6860).
1580+ Remove the `\strut` that was added at the end of minipage
1581+ environments in cells. Replace `\tabularnewline` with
1582+ `\\ \addlinespace`.
1583+ + Improve calculation of column spacing (#6883).
1584+ + Extract table handling into separate module (Albert Krewinkel).
1585+ + Fix bug with nested `csl-` display Spans (#6921).
1586+ + Improve longtable output (#6883). Don't create minipages for
1587+ regular paragraphs. Put width and alignment information in the
1588+ longtable column descriptors.
1589+
1590+ * OpenDocument writer:
1591+
1592+ + Support for table width as a percentage of text width
1593+ (#6792, Nils Carson).
1594+ + Implement Div and Span ident support (#6755, Nils Carson).
1595+ Spans and Divs containing an ident in the Attr will become bookmarks
1596+ or sections with idents in OpenDocument format.
1597+ + Add two extensions, `xrefs_name` and `xrefs_number` (#6774, Nils
1598+ Carlson). Links to headings, figures and tables inside the
1599+ document are substituted with cross-references that will use the
1600+ name or caption of the referenced item for `xrefs_name` or the
1601+ number for `xrefs_number`. For the `xrefs_number` to be useful
1602+ heading numbers must be enabled in the generated document and
1603+ table and figure captions must be enabled using for example the
1604+ `native_numbering` extension. In order for numbers and reference
1605+ text to be updated the generated document must be refreshed.
1606+
1607+ * JATS writer:
1608+
1609+ + Support advanced table features (Albert Krewinkel).
1610+ + Support author affiliations (#6687, Albert Krewinkel).
1611+
1612+ * Docbook writer:
1613+
1614+ + Use correct id attribute consistently (Jan Tojnar).
1615+ DocBook5 should always use `xml:id` instead of `id`.
1616+ + Handle admonition titles better (Jan Tojnar).
1617+ Docbook reader produces a `Div` with `title` class for `<title>`
1618+ element within an “admonition” element. Markdown writer then turns
1619+ this into a fenced div with `title` class attribute. Since fenced
1620+ divs are block elements, their content is recognized as a
1621+ paragraph by the Markdown reader. This is an issue for Docbook
1622+ writer because it would produce an invalid DocBook document from
1623+ such AST – the `<title>` element can only contain “inline”
1624+ elements. Handle this special case separately by unwrapping
1625+ the paragraph before creating the `<title>` element.
1626+ + Add XML namespaces to top-level elements (#6923, Jan Tojnar).
1627+ Previously, we only added `xmlns` attributes to chapter
1628+ elements, even when running with `--top-level-division=section`.
1629+ These namespaces are now added to part and section elements too,
1630+ when they are the selected top-level divisions.
1631+ We do not need to add namespaces to documents produced with
1632+ `--standalone` flag, since those will already have xmlns attribute on
1633+ the root element in the template.
1634+
1635+ * HTML writer:
1636+
1637+ + Fix handling of nested `csl-` display spans (#6921).
1638+ Previously inner Spans used to represent CSL display attributes were
1639+ not rendered as div tags as intended.
1640+
1641+ * EPUB writer:
1642+
1643+ + Include title page in landmarks (#6919).
1644+ Note that the toc is also included if `--toc` is specified.
1645+ + Add frontmatter type on body element for nav.xhtml (#6918).
1646+
1647+ * EPUB templates: use preserveAspectRatio="xMidYMid" for cover image (#6895,
1648+ Shin Sang-jae). This change affects both the epub2 and the epub3
1649+ templates. It avoids distortion of the cover image by requiring that the
1650+ aspect ratio be preserved.
1651+
1652+ * LaTeX template:
1653+
1654+ + Include `csquotes` package if `csquotes` variable set.
1655+ + Put back `amssymb`. We need it for checkboxes in todo lists,
1656+ and maybe for other things. In this location it seems compatible
1657+ with the cases that prompted #6469 and PR #6762.
1658+ + Disable language-specific shorthands in babel (#6817, #6887).
1659+ Babel defines "shorthands" for some languages, and these can
1660+ produce unexpected results. For example, in Spanish, `1.22`
1661+ gets rendered as `122`, and `et~al.` as `etal`.
1662+ One would think that babel's `shorthands=off` option (which
1663+ we were using) would disable these, but it doesn't. So we
1664+ remove `shorthands=off` and add some code that redefines
1665+ the shorthands macro. Eventually this will be fixed in babel,
1666+ I hope, and we can revert to something simpler.
1667+
1668+ * JATS template: allow array of persistent institute ids in `pid`
1669+ (Albert Krewinkel).
1670+
1671+ * Text.Pandoc.Parsing: minor code and efficiency improvements.
1672+
1673+ * Text.Pandoc.Extension:
1674+
1675+ + Add `Ext_sourcepos` constructor for `Extension` [API change].
1676+ + Add `Ext_xrefs_name` and `Ext_xrefs_number` constructors for
1677+ `Extension` (Nils Carson) [API change].
1678+
1679+ * Text.Pandoc.Citeproc:
1680+
1681+ + Fix truncation of `[Citation]` list in `Cite` inside footnotes (#6890).
1682+ This affected author-in-text citations in footnotes. It didn't cause
1683+ problems for the printed output, but for filters that expected the
1684+ citation id and other information.
1685+ + Allow the use of both inline and external references (#6951),
1686+ as with pandoc-citeproc. References defined in the document's
1687+ metadata take priority over references with the same id defined in
1688+ an external bibliography.
1689+ + Use `fetchItem` to get external bibliography (#6940).
1690+ + Ensure that BCP47 lang codes can be used. We ignore the variants
1691+ and just use the base lang code and country code when passing off
1692+ to citeproc.
1693+ + Citeproc BibTeX parser: revert change in `getRawField`
1694+ which was made (for reasons forgotten) when transferring
1695+ this code from pandoc-citeproc. The change led to `--` in
1696+ URLs being interpreted as en-dashes, which is unwanted (#6874).
1697+
1698+ * Text.Pandoc.ImageSize:
1699+
1700+ + Default to DPI 72 if the format specifies DPI of 0 (#6880).
1701+ This shouldn't happen, in general, but it can happen with
1702+ JPEGs that don't conform to the spec. Having a DPI of 0
1703+ will blow up size calculations (division by 0).
1704+ + ImageSize: use JuicyPixels to determine size for png, jpeg, and
1705+ gif, instead of doing our own binary parsing (#6936). This
1706+ gives more reliable results.
1707+
1708+ * Text.Pandoc.CSS:
1709+
1710+ + Remove `foldOrElse` (internal module) (Albert Krewinkel).
1711+
1712+ * Use skylighting 0.10.2 (#6625).
1713+
1714+ * Use citeproc 0.3. This fixes issues with references with
1715+ duplicate ids (jgm/citeproc#36).
1716+
1717+ * Use doctemplates 0.9. This fixes issues with boolean
1718+ metadata values in the Markdown writer (#6388)
1719+ and in `meta-json` (#6650). It also fixes
1720+ issues with nested for loops in templates.
1721+
1722+ * Add translations zh-Hans.yaml and zh-Hant.yaml (#6904, #6909,
1723+ Kolen Cheung, taotieren).
1724+
1725+ * Add tests: True to cabal.project.
1726+ This fixes some CI failures for cabal.
1727+
1728+ * Normalize test/tables/*.native (#6888, Kolen Cheung).
1729+
1730+ * Move executable to `app` directory to avoid problems with cabal repl.
1731+
1732+ * CONTRIBUTING: add section "How can I help?" (#6892, Albert Krewinkel).
1733+ Also adds a paragraph aimed at highlighting the importance of feature
1734+ maintenance.
1735+
