Ormolu 0.1.0.0

Fixed rendering of type signatures concerning several identifiers. Issue 566.
Fixed an idempotence issue with inline comments in tuples and parentheses. Issue 450.
Fixed an idempotence issue when certain comments where picked up as “continuation” of a series of comments Issue 449.
Fixed an idempotence issue related to different indentation levels in a comment series. Issue 512.
Fixed an idempotence issue related to comments which may happen to be separated from the elements they are attached to by the equality sign. Issue 340.
Fixed an idempotence issue with type synonym and data declarations where the type has a Haddock. Issue 578.
Fix the false positive about AST differences in presence of comments with multiple blank lines in a row. Issue 518.
Fixed rendering of comment around if expressions. Issue 458.
Unnamed fields of data constructors are now documented using the -- ^ syntax. Issue 445 and Issue 428.
Fixed non-idempotent transformation of partly documented data definition. Issue 590.
Fixed an idempotence issue related to operators. Issue 522.
Renamed the --check-idempotency flag to --check-idempotence. Apparently only the latter is correct.

Grouping of statements in do-blocks is now preserved. Issue 74.
Grouping of TH splices is now preserved. Issue 507.
Comments on pragmas are now preserved. Issue 216.
Ormolu can now be enabled and disabled via special comments. Issue 435.
Added experimental support for simple CPP. Issue 415.
Added two new options --start-line and --end-line that allow us to select a region to format. Issue 516.
Fixed rendering of module headers in the presence of preceding comments or Haddocks. Issue 561.

When given several files to format, Ormolu does not stop on the first failure, but tries to format all the files. Issue 502.
Made rendering of pattern matches involving operators consistent with other cases of rendering of operators. Issue 500.
More compact rendering of type family injectivity constraints. Issue 482.
Improved rendering of the keyword where in class, data, and type family declarations. When headers of these declarations are multi-line where is now put on its own line. Issue 509.
Fixed the bug pertaining to rendering of arrow notation with multiline expressions. Issue 513.
Made rendering of data type definitions, value-level applications, and application of types use the same style. Moreover, existential now doesn't cause the data constructor be unconditionally rendered in multiline layout. Issue 427.
Records with a single data constructor are now formatted more compactly. Issue 425.
Switched to ghc-lib-parser-8.10.1.
Implemented support for the new language extensions ImportQualifiedPost and StandaloneKindSignatures.

Fixed rendering of record updates with the record dot preprocessor syntax Issue 498.

Fixed an issue related to unnecessary use of curly braces. Issue 473.
Fixed the issue with formatting multi-way if when it happens to be a function applied to arguments Issue 488. This changed the way multi-line if is formatted in general.
Added support for record dot pre-processor when used via the plugin. Issue 486.
Stopped hanging record constructors and improved placing potentially-hanging consturctions in the presence of comments. Issue 447.
Fixed indentation in presence of type applications. Issue 493.
Class and instance declarations now do not have a blank line after where. Grouping of methods from the original input is also preserved with some normalizations. Issue 431.

Switched to ghc-lib-parser instead of depending on the ghc package directly. This should allow us to use newest features of GHC while not necessarily depending on the newest version of the compiler. In addition to that Ormolu is now GHCJS-compatible.
Now unrecognized GHC options passed with --ghc-opt cause Ormolu to fail (exit code 7).
Fixed formatting of result type in closed type families. See issue 420.
Fixed a minor inconsistency between formatting of normal and foreign type signatures. See issue 408.
Fixed a bug when comment before module header with Haddock was moved inside the export list. See issue 430.
Empty foralls are now correctly preserved. See issue 429.
Fixed issue 446, which involved braces and operators.
When there are comments between preceding Haddock (pipe-style) and its corresponding declaration they are preserved like this in the output instead of being shifted. To be clear, this is not a very good idea to have comments in that position because the Haddock will end up not being associated with the declarations. Issues 440 and 448.
Implemented correct handling of shebangs. Issue 377.
Implemented correct handling of stack headers. Issue 393.
Sorting language pragmas cannot not change meaning of the input program anymore. Issue 404.
Fixed formatting of applications where function is a complex expression. Issue 444.
