Radosław Waśko 2385f5b357
Add size-limited strings and varying bit-width integer Value_Types to in-memory backend and check for ArithmeticOverflow in LongStorage (#7557) 
- Closes #5159
- Now data downloaded from the database can keep the type much closer to the original type (like string length limits or smaller integer types).
- Cast also exposes these types.
- The integers are still all stored as 64-bit Java `long`s, we just check their bounds. Changing underlying storage for memory efficiency may come in the future: #6109
- Fixes #7565
- Fixes #7529 by checking for arithmetic overflow in in-memory integer arithmetic operations that could overflow. Adds a documentation note saying that the behaviour for Database backends is unspecified and depends on particular database.

# Next Release
#### Visual Environment
- [Camera is panned to newly created nodes.][3552]
- [Long names on the Node Searcher's list are truncated.][3373] The part of the
name that doesn't fit in the Searcher's window is replaced with an ellipsis
character ("…").
- [Magnet Alignment algorithm is used while placing new nodes][3366]. When we
find an available free space for a new node, the node gets aligned with the
surrounding nodes horizontally and vertically. This helps to preserve a nice
grid-like layout for all the nodes.
- [Nodes created via the <kbd>TAB</kbd> key or by clicking the (+) button on the
screen are now placed below all the selected nodes when more than one node is
selected.][3361] (Previously, they were placed below the first node that was
selected.) This makes it easier to achieve a compact, vertical layout of the
graph.
- [Nodes created near existing nodes via the <kbd>TAB</kbd> key or by dropping a
connection are now repositioned and aligned to existing nodes.][3301] This is
to make the resulting graph prettier and avoid overlapping. In such cases,
created nodes will be placed below an existing node or on the bottom-left
diagonal if there is no space underneath.
- [Nodes can be added to the graph by double-clicking the output ports of
existing nodes (or by clicking them with the right mouse button).][3346]
- [Node Searcher preserves its zoom factor.][3327] The visible size of the node
searcher and edited node is now fixed. It simplifies node editing on
non-standard zoom levels.
- [Nodes can be added to the graph by clicking (+) button on the screen][3278].
The button is in the bottom-left corner. Node is added at the center or pushed
down if the center is already occupied by nodes.
- [Maximum zoom factor is limited to 1.0x if IDE is not in Debug Mode.][3273]
- [Debug Mode for Graph Editor can be activated/deactivated using a
shortcut.][3264] It allows access to a set of restricted features. See
[debug-shortcuts].
- [New nodes can be created by dragging and dropping a connection on the
scene.][3231]
- [Node connections can be dropped by pressing the Esc key while dragging
them.][3231]
- [Added support of source maps for JS-based visualizations.][3208]
- [Fixed the alignment of newly created nodes to existing nodes with
visualizations enabled.][3361] When applicable, new nodes are now placed below
visualizations. (Previously, they were placed to the left of the
visualizations.)
- [Fixed histograms coloring and added a color legend.][3153]
- [Lazy visualization for scatter plot.][3655]
- [Fixed broken node whose expression contains non-ASCII characters.][3166]
- [Fixed developer console warnings about views being created but not
registered.][3181]
- [Fixed developer console errors related to Language Server (mentioning code
3003 and "Invalid version"), occurring during project opening and after new
node cration.][3186]
- [Fixed developer console error about failing to decode a notification
"executionContext/visualisationEvaluationFailed"][3193]
- [New Version of the Node Searcher - the Component Browser][3530] The available
methods, atoms and functions are presented in nice, categorized view. The most
popular tools are available at hand. The panel is unstable, and can be
disabled with the `--enable-new-component-browser=false` flag.
- [Fixed error handling during startup.][3648] This prevents entering IDE into a
"zombie" state, where processes were started but not visible to user. They
could cause issues with starting further IDE instances.
- [New nodes are created in the project source when the searcher is opened and a
new node is created.][3645]
- [Proper Polyglot Vector and Array Support][3667]
- [IDE uses new visualization API.][3661]
- [Visualization of long textual values improved][3665]
- [Selecting a suggestion from the searcher or component browser now updates the
visualisation of the edited node to preview the results of applying the
suggestion.][3691]
- [Remove here keyword from IDE.][3749]
- [Shortcut changes:][3823] Pressing `Enter` when no node is edited opens
Component Browser. Entering node shortcut changed to `cmd` + `Enter`.
- [Added support for scrolling by pressing and holding a mouse button on a
scrollbar.][3824]
- [Added scroll bounce animation][3836] which activates when scrolling past the
end of scrollable content.
- [The default text visualisation now loads its content lazily from the
backend][3910]. This means that the visualisation cannot be overwhelmed by
large amounts of data.
- [Added project snapshot saving on shortcut][3923]
- [The color of the displayed project name indicates whether the project's
current state is saved in a snapshot.][3950] The project name is darker when
the project is changed from the last saved snapshot and lighter when the
snapshot matches the current project state.
- [Added shortcut to interrupt the program][3967]
- [Added suggestion dropdown for function arguments][4013]. The dropdown is
present only when the argument is of type that has a predefined set of values.
- [Separate component browser navigator sections for modules imported from
different namespaces][4044]
- [Internal components (private API) are not displayed in the component
browser.][4085]
- [The correct default visualisation for tables is shown on new nodes.][4120]
- [Added restoring of last project snapshot on shortcut.][4050]
- [Added contextual suggestions to argument dropdowns][4072]. Dropdowns will now
contain suggestions which are based on evaluated data.
- [Added a shortcut to show internal components (private API) in the component
browser.][5582]
- [Improved component browser entry filtering and sorting][5645]. The component
browser will now provide suggestions matching either the component's label or
the corresponding code.
- [Improved argument placeholder resolution in more complex expressions][5656].
It is now possible to drop node connections onto missing arguments of chained
and nested function calls.
- [The component browser suggestions take into account entry aliases][5678]. The
searcher input is now matched to entry aliases too. The alias match is used to
filter and sort component browser entries.
- [The Component Browser icons are cached on texture][5779] improving its
performance on slower machines.
- [Fixed missing result preview when editing nodes.][5757]
- [Application retries its initialization after failures][5802], allowing a
reconnecting after connectivity problems.
- [Improved Component Browser Filtering][4115]. The best match is always
selected first, and the groups are rearranged, so the best matches are on the
bottom.
- [Named arguments syntax is now recognized in IDE][5774]. Connections to
function arguments will now use named argument syntax instead of inserting
wildcards on all preceding arguments.
- [Added boilerplate React app for authorization via Cognito+AWS Amplify][5798].
This PR adds a React app that renders the dashboard (which has been ported
from the cloud. The dashboard displays a list of projects, and allows users to
open them in the IDE (which is not part of the React app, but can be switched
to from the dashboard). The PR also adds authentication+authorization (i.e.,
sign up and sign in for users), via either email/password or GitHub/Google.
- [New Enso documentation parser][5917]. Smaller and faster; enables planned
improvements to internal documentation representation.
- [Dropdown widgets now support custom labels][5705] and automatically generate
shortened labels for entries with long module paths. When an option is
selected from the dropdown, the necessary module imports are inserted,
eliminating the need for fully qualified names.
- [The IDE now has a new UI element for selecting the execution mode of the
project][6130].
- [Added tooltips to icon buttons][6035] for improved usability. Users can now
quickly understand each button's function.
- [File associations are created on Windows and macOS][6077]. This allows
opening Enso files by double-clicking them in the file explorer.
- [AI-powered code completions][5910]. It is now possible to get AI-powered
completions when using node searcher with Tables.
- [Added capability to create node widgets with complex UI][6347]. Node widgets
such as dropdown can now be placed in the node and affect the code text flow.
- [The IDE UI element for selecting the execution mode of the project is now
sending messages to the backend.][6341].
- [Feedback when renaming a project][6366]. When the user tries to rename the
project to an invalid name, a helpful error message is shown and the text
field stays the same as to give the user the opportunity to fix the mistake.
- [Area selectionof nodes no longer takes into account the visualisation that
belongs to the node.][6487].
- [List Editor Widget][6470]. Now you can edit lists by clicking buttons on
nodes or by dragging the elements.
- [Visualisations now show a loading spinner while waiting on data.][6512].
- [Fixed text visualisations which were being cut off at the last line.][6421]
- [Fixed a bug where, when scrolling or dragging on a full-screen visualization,
the view of the graph changed as well.][6530]
- [Changed the shortcut for restoring to the last saved version of a project
from <kbd>cmd</kbd>+<kbd>r</kbd> to
<kbd>cmd</kbd>+<kbd>shift</kbd>+<kbd>r</kbd>][6620] to make it less likely
that it would be triggered by accident. As a consequence, the program
execution shortcuts changed from
<kbd>cmd</kbd>+<kbd>shift</kbd>+<kbd>t</kbd>/<kbd>r</kbd> to
<kbd>cmd</kbd>+<kbd>alt</kbd>+<kbd>t</kbd>/<kbd>r</kbd>.
- [Fixed a bug where selecting a nested breadcrumb would cause the order of
breadcrumbs to change incorrectly.][6617]
- [Changed the shortcut to show the full-screen visualization for a node from
<kbd>space</kbd> <kbd>space</kbd> to <kbd>shift</kbd>+<kbd>space</kbd>.][6663]
so that it doesn't interfere with the shortcut for toggling the small
visualization.
- [Cloud dashboard, which supersedes the startup screen][6279]. Features also
added in various other PRs. The new dashboard includes tables for projects,
folders, files and secrets, a list of templates from which new projects can be
created, a user menu, and a search bar.
- [The Application will try to reload file in backend on synchronization
failure][6752]. It should make it more resilient to connectivity issues and
occasional bugs. The reload may be forced by the user with
<kbd>cmd</kbd>+<kbd>shift</kbd>+<kbd>x</kbd> shortcut.
- [When selecting a function from the main module through the component browser,
it is now referenced via the `Main` namespace instead of the project
namespace,][6719] e.g. `Main.func1` instead of `MyProject.func1`. This makes
it robust against project name changes.
- [Added a button to return from an opened project back to the project
dashboard.][6474]
- [Keyboard shortcuts for graph editing are now disabled when the full-screen
visualization is active.][6844]
- [A loading animation is now shown when opening and creating projects][6827],
as the previous behaviour of showing a blank screen while the project was
being loaded was potentially confusing to users.
- [Error message is displayed in the status bar when the backend reports
execution failed][6918].
- [Performance and readability of documentation panel was improved][6893]. The
documentation is now split into separate pages, which are much smaller.
- [IDE no longer inserts redundant imports when selecting options from dropdown
widgets][7028]. The code was unified with the component browser, and it now
correctly handles reexports and already existing imports.
- [Fixed cursor position when ctrl-clicking the node][7014]. Sometimes
ctrl-clicking to edit the node placed the mouse cursor in the wrong position
in the text. This is fixed now.
- [Added prototype AI Searcher that can be used to create new nodes from natural
language input][7146]
- [Allow visualization resizing][7164]. Now the user can adjust the
visualization size by dragging its right and bottom borders. Visualization
width also follows the node's width, and visualizations are aligned to the
left side of the node.
- [Component Browser was redesigned][7372]. The three columns of groups turned
out to be non-practical, as they give too much information to comprehend.
Also, filtering results was kept in groups making second-best match not easily
available. Therefore, we introduced a new, impler CB design with single
column.
- [Help chat][7151]. The link to the Discord server is replaced with a chat
bridge to the Discord server. This is intended to have the chat visible at the
same time as the IDE, so that help can be much more interactive.
- [New breadcrumbs design][7362]. Breadcrumbs now optionally show the icon of
the item they represent. They also follow the new design of the component
browser.
- [The libraries' authors may put entities to groups by adding GROUP tag in the
docstring]. It was requested as more convenient way than specifying full names
in package.yaml.
- [Graph editor node was redesigned][7311]. Nodes have a color and icon matching
the selected entry in the component browser. Clear separating lines between
method arguments were added. The node selection was made easier with
additional thick interactive selection border.
- [The shortcut for opening Component Browser was changed to
<kbd>enter</kbd>][7527]
- [Connections to lamdas are displayed correctly][7550]. It is possible to drag
a connection to any expression inside the lambda body.

#### EnsoGL (rendering engine)
- [You can change font and set letters bold in the <code>text::Area</code>
component][3385]. Use the <code>set_font</code> and
<code>set_bold_bytes</code> respectively.
- [Fixed a text rendering issue in nested sublayer][3486].
- [Added a new component: Grid View.][3588] It's parametrized by Entry object,
display them arranged in a Grid. It does not instantiate all entries, only
those visible, and re-use created entries during scrolling thus achieving
great performance. There are variants of grid view with selection and
highlight, scrollbars, and both.
- [Massive improvements of text rendering performance][3776]. Different text
instances are now reusing the shape shaders and the same sprite system under
the hood. This drastically reduces the amount of required draw calls for
scenes with a lot of text.
- [Text rendering quality improvements][3855]. Glyphs are now hinted in a better
way. Also, additional fine-tuning is performed per font and per host operating
system.
- [Display objects can now emit and receive events in the same style as
JavaScript DOM events][3863]. The events system implements very similar
behavior to the one described here:
https://javascript.info/bubbling-and-capturing.
- [Added a new component: Slider][3852]. It allows adjusting a numeric value
with the mouse. The precision of these adjustments can be increased or
decreased.
- [Slider component functionality improvements][3885]. The slider component now
supports multiple ways to handle out-of-range values. The slider's value can
be edited as text, and a new vertical slider layout is available.
- [Added ProjectsGrid view for Cloud Dashboard][3857]. It provides the first
steps towards migrating the Cloud Dashboard from the existing React (web-only)
implementation towards a shared structure that can be used in both the Desktop
and Web versions of the IDE.
- [Removed Cloud Dashboard][4047]. The Cloud Dashboard was being rewritten in
EnsoGL but after internal discussion we've decided to rewrite it in React,
with a shared implementation between the Desktop and Web versions of the IDE.
- [Added a new component: Dropdown][3985]. A list of selectable labeled entries,
suitable for single and multi-select scenarios.
- [Compile-time shader optimizer was implemented][4003]. It is capable of
extracting non-optimized shaders from the compiled WASM artifacts, running
stand-alone optimization toolchain (glslc, spirv-opt, spirv-cross), and
injecting optimized shaders back to WASM during its initialization process.
Unfortunately, it caused our theme system to stop working correctly, because
generated shaders differ per theme (only light theme is available, the dark
theme has been disabled). We will support multiple themes in the future, but
this is not on our priority list right now.
- [Performance monitor was extended with the ability to print details of actions
performed in a given frame][5895]. In particular, you can now inspect names of
all symbols rendered in a given frame. You can also pause the performance
monitor and inspect results recorded in the past.
- [ToggleButtons can now have tooltips][6035].
- [Rendering of tooltips was improved.][6097] Their text is now more vertically
centered and the delay before showing them was extended.
- [Accurate GPU performance measurements have been implemented][6595]. It is
possible now to track both the time spent on both the CPU and the GPU sides.

# Enso 2.0.0-alpha.18 (2021-10-12)
<br/>![New Features](/docs/assets/tags/new_features.svg)
#### Enso Compiler
- [Updated Enso engine to version 0.2.30][engine-0.2.31]. If you're interested
in the enhancements and fixes made to the Enso compiler, you can find their
release notes
[here](https://github.com/enso-org/enso/blob/develop/RELEASES.md).
<br/>![Bug Fixes](/docs/assets/tags/bug_fixes.svg)
#### Visual Environment
- [Fixed freezing after inactivity.][1776] When the IDE window was minimized or
covered by other windows or invisible for any other reason for a duration
around one minute or longer then it would often be frozen for some seconds on
return. Now it is possible to interact with the IDE instantly, no matter how
long it had been inactive.
<br/>

# Enso 2.0.0-alpha.17 (2021-09-23)
<br/>![Bug Fixes](/docs/assets/tags/bug_fixes.svg)
#### Visual Environment
- [Correct handling of command-line flags.][1815] Command line arguments of the
form `--backend=false` or `--backend false` are now handled as expected and
turn off the "backend" option. The same fix has been applied to all other
boolean command-line options as well.
- [Visualizations will be attached after project is ready.][1825] This addresses
a rare issue when initially opened visualizations were automatically closed
rather than filled with data.

# Enso 2.0.0-alpha.16 (2021-09-16)
<br/>![New Features](/docs/assets/tags/new_features.svg)
#### Visual Environment
- [Auto-layout for new nodes.][1755] When a node is selected and a new node gets
created below using <kbd>Tab</kbd> then the new node is automatically
positioned far enough to the right to find sufficient space and avoid
overlapping with existing nodes.
[1755]: https://github.com/enso-org/ide/pull/1755

<br/>![Bug Fixes](/docs/assets/tags/bug_fixes.svg)
#### Visual Environment
- [Fixed parsing of the `--no-data-gathering` command line option.][1831] Flag's
name has been changed to `--data-gathering`, so now `--data-gathering=false`
and `--data-gathering=true` are supported as well.
[1831]: https://github.com/enso-org/ide/pull/1831
# Enso 2.0.0-alpha.14 (2021-09-02)
<br/>![New Features](/docs/assets/tags/new_features.svg)
#### Visual Environment
- [Visualization previews are disabled.][1817] Previously, hovering over a
node's output port for more than four seconds would temporarily reveal the
node's visualization. This behavior is disabled now.

# Enso 2.0.0-alpha.6 (2021-06-28)
<br/>![New Features](/docs/assets/tags/new_features.svg)
#### Visual Environment
- [Profling mode.][1546] The IDE contains a profiling mode now which can be
entered through a button in the top-right corner or through the keybinding
<kbd>ctrl</kbd>+<kbd>p</kbd>. This mode does not display any information yet.
In the future, it will display the running times of nodes and maybe more
useful statistics.
- [Area selection][1588]. You can now select multiple nodes at once. Just click
and drag on the background of your graph and see the beauty of the area
selection appear.
- [Opening projects in application graphical interface][1587]. Press `cmd`+`o`
to bring the list of projects. Select a project on the list to open it.
- [Initial support for undo-redo][1602]. Press <kbd>cmd</kbd>+<kbd>z</kbd> to
undo last action and <kbd>cmd</kbd>+<kbd>z</kbd> to redo last undone action.
This version of undo redo does not have proper support for text editor and
undoing UI changes (like selecting nodes).
#### EnsoGL (rendering engine)
<br/>![Bug Fixes](/docs/assets/tags/bug_fixes.svg)
#### Visual Environment
- [Nodes in graph no longer overlap panels][1577]. The Searcher, project name,

# Enso 2.0.0-alpha.5 (2021-05-14)
<br/>![New Features](/docs/assets/tags/new_features.svg)
#### Visual Environment
- [Create New Project action in Searcher][1566]. When you bring the searcher
with tab having no node selected, a new action will be available next to the
examples and code suggestions: `Create New Project`. When you choose it by
clicking with mouse or selecting and pressing enter, a new unnamed project
will be created and opened in the application. Then you can give a name to
this project.
- [Signed builds.][1366] Our builds are signed and will avoid warnings from the
operating system about being untrusted.
#### EnsoGL (rendering engine)
- [Components for picking numbers and ranges.][1524]. We now have some internal
re-usable UI components for selecting numbers or a range. Stay tuned for them
appearing in the IDE.
<br/>![Bug Fixes](/docs/assets/tags/bug_fixes.svg)
#### Visual Environment
- [Delete key will delete selected nodes][1538]. Only the non-intuitive
backspace key was assigned to this action before.
- [It is possible to move around after deleting a node with a selected
visualization][1556]. Deleting a node while its attached visualization was
selected made it impossible to pan or zoom around the stage afterwards. This
error is fixed now.
- [Fixed an internal error that would make the IDE fail on some browser.][1561].
Instead of crashing on browser that don't support the feature we use, we are
now just start a little bit slower.
#### Enso Compiler
- [Updated Enso engine to version 0.2.11][1541].

# Enso 2.0.0-alpha.4 (2021-05-04)
<br/>![New Features](/docs/assets/tags/new_features.svg)
#### Visual Environment
- [Window management buttons.][1511]. The IDE now has components for
"fullscreen" and "close" buttons. They will when running IDE in a cloud
environment where no native window buttons are available.
- [Customizable backend options][1531]. When invoking Enso IDE through command
line interface, it is possible to add the `--` argument separator. All
arguments following the separator will be passed to the backend.
- [Added `--verbose` parameter][1531]. If `--verbose` is given as command line
argument, the IDE and the backend will produce more detailed logs.
<br/>![Bug Fixes](/docs/assets/tags/bug_fixes.svg)
#### Visual Environment
- [Some command line arguments were not applied correctly in the IDE][1536].
Some arguments were not passed correctly to the IDE leading to erroneous
behavior or appearance of the electron app. This is now fixed.

# Enso 2.0.0-alpha.3 (2020-04-13)
<br/>![New Learning Resources](/docs/assets/tags/new_learning_resources.svg)
<br/>![New Features](/docs/assets/tags/new_features.svg)
#### Visual Environment
- [The status bar reports connectivity issues][1316]. The IDE maintains a
connection to the Enso Language Server. If this connection is lost, any
unsaved and further work will be lost. In this build we have added a
notification in the status bar to signal that the connection has been lost and
that the IDE must be restarted. In future, the IDE will try to automatically
reconnect.
- [Visualizations can now be maximised to fill the screen][1355] by selecting
the node and pressing space twice. To quit this view, press space again.
- [Visualizations are previewed when you hover over an output port.][1363] There
is now a quick preview for visualizations and error descriptions. Hovering
over a node output will first show a tooltip with the type information and
then, after some time, will show the visualization of the node. This preview
visualization will be located above other nodes, whereas the normal view, will
be shown below nodes. Errors will show the preview visualization immediately.
Nodes without type information will also show the visualization immediately.
You can enter a quick preview mode by pressing ctrl (or command on macOS),
which will show the preview visualization immediately when hovering above a
node's output port.
- [Database Visualizations][1335]. Visualizations for the Database library have
been added. The Table visualization now automatically executes the underlying
query to display its results as a table. In addition, the SQL Query
visualization allows the user to see the query that is going to be run against
the database.
- [Histogram and Scatter Plot now support Dataframes.][1377] The `Table` and
`Column` datatypes are properly visualized. Scatter Plot can display points of
different colors, shapes and sizes, all as defined by the data within the
`Table`.
- [Many small visual improvements.][1419] See the source issue for more details.
- The dark theme is officially supported now. You can start the IDE with the
`--theme=dark` option to enable it.
- You can hide the node labels with the `--no-node-labels` option. This is
useful when creating demo videos.
- [Added a Heatmap visualization.][1438] Just as for the Scatter Plot, it
supports visualizing `Table`, but also `Vector`.
- [Add a background to the status bar][1447].
- [Display breadcrumbs behind nodes and other objects][1471].
- [Image visualization.][1367]. Visualizations for the Enso Image library. Now
you can display the `Image` type and a string with an image encoded in base64.
The histogram visualization has been adjusted, allowing you to display the
values of the precomputed bins, which is useful when the dataset is relatively
big, and it's cheaper to send the precomputed bins rather than the entire
dataset.
- [Output type labels.][1427] The labels, that show the output type of a node on
hover, appear now in a fixed position right below the node, instead of a
pop-up, as they did before.
<br/>![Bug Fixes](/docs/assets/tags/bug_fixes.svg)
#### Visual Environment
- [Not adding spurious imports][1209]. Fixed cases where the IDE was adding
unnecessary library imports when selecting hints from the node searcher. This
makes the generated textual code much easier to read, and reduces the
likelihood of accidental name collisions.
- [Hovering over an output port shows a pop-up with the result type of a
node][1312]. This allows easy discovery of the result type of a node, which
can help with both debugging and development.
- [Visualizations can define the context for preprocessor evaluation][1291].
Users can now decide which module's context should be used for visualization
preprocessor. This allows providing visualizations with standard library
functionalities or defining utilities that are shared between multiple
visualizations.
- [Fixed an issue with multiple instances of the IDE running.][1314] This fixes
an issue where multiple instances of the IDE (or even other applications)
could lead to the IDE not working.
- [Allow JS to log arbitrary objects.][1313] Previously using `console.log` in a
visualisation or during development would crash the IDE. Now it correctly logs
the string representation of the object. This is great for debugging custom
visualizations.
- [Fix the mouse cursor offset on systems with fractional display
scaling][1064]. The cursor now works with any display scaling, instead of
there being an offset between the visible cursor and the cursor selection.
- [Disable area selection][1318]. The area selection was visible despite being
non-functional. To avoid confusion, area selection has been disabled until it
is [correctly implemented][479].
- [Fix an error after adding a node][1332]. Sometimes, after picking a
suggestion, the inserted node was spuriously annotated with "The name could
not be found" error.
- [Handle syntax errors in custom-defined visualizations][1341]. The IDE is now
able to run properly, even if some of the custom visualizations inside a
project contain syntax errors.
- [Fix issues with pasting multi-line text into single-line text fields][1348].
The line in the copied text will be inserted and all additional lines will be
ignored.
- [Users can opt out of anonymous data gathering.][1328] This can be done with
the `--no-data-gathering` command-line flag when starting the IDE.
- [Provide a theming API for JavaScript visualizations][1358]. It is now
possible to use the Enso theming engine while developing custom visualizations
in JavaScript. You can query it for all IDE colors, including the colors used
to represent types.
- [You can now start the IDE service without a window again.][1353] The command
line argument `--no-window` now starts all the required backend services
again, and prints the port on the command line. This allows you to open the
IDE in a web browser of your choice.
- [JS visualizations have gestures consistent with the IDE][1291]. Panning and
zooming now works just as expected using both a trackpad and mouse.
- [Running `watch` command works on first try.][1395]. Running the build command
`run watch` would fail if it was run as the first command on a clean
repository. This now works.
- [The `inputType` field of visualizations is actually taken into
consideration][1384]. The visualization chooser shows only the entries that
work properly for the node's output type.
- [Fix applying the output of the selected node to the expression of a new
node][1385]. For example, having selected a node with `Table` output and
adding a new node with expression `at "x" == "y"`, the selected node was
applied to the right side of `==`: `at "x" == operator1."y"` instead of
`operator1.at "x" == "y"`.
- [`Enso_Project.data` is visible in the searcher][1393].
- [The Geo Map visualization recognizes columns regardless of the case of their
name][1392]. This allows visualizing tables with columns like `LONGITUDE` or
`Longitude`, where previously only `longitude` was recognized.
- [It is possible now to switch themes][1390]. Additionally, the theme manager
was integrated with the FRP event engine, which has been a long-standing issue
in the IDE. Themes management was exposed to JavaScript with the
`window.theme` variable. It is even possible to change and develop themes live
by editing theme variables directly in the Chrome Inspector. Use the following
command to give this a go:
`theme.snapshot("t1"); theme.get("t1").interactiveMode()`.
- [The active visualization is highlighted.][1412] Now it is clearly visible
when the mouse events are passed to the visualization.
- [Fixed an issue where projects containing certain language constructs failed
to load.][1413]
- [Fixed a case where IDE could lose connection to the backend after some
time.][1428]
- [Improved the performance of the graph editor, particularly when opening a
project for the first time.][1445]
#### EnsoGL (rendering engine)
- [Unified shadow generation][1411]. Added a toolset to create shadows for
arbitrary UI components.

# Enso 2.0.0-alpha.2 (2020-03-04)
This is a release focused on bug-fixing, stability, and performance. It improves
the performance of workflows and visualizations, and improves the look and feel
of the graphical interface. In addition, the graphical interface now informs the
users about errors and where they originate.
<br/>![New Learning Resources](/docs/assets/tags/new_learning_resources.svg)
- [Learn how to define custom data visualizations in
Enso][podcast-custom-visualizations].
- [Learn how to use Java libraries in Enso, to build a
webserver][podcast-java-interop].
- [Learn how to use Javascript libraries in Enso, to build custom server-side
website rendering][podcast-http-server].
- [Discover why Enso Compiler is so fast and how it was built to support a
dual-representation language][podcast-compiler-internals].
- [Learn more about the vision behind Enso and about its planned
future][podcast-future-of-enso].
<br/>![New Features](/docs/assets/tags/new_features.svg)
#### Visual Environment
- [Errors in workflows are now displayed in the graphical interface][1215].
Previously, these errors were silently skipped, which was non-intuitive and
hard to understand. Now, the IDE displays both dataflow errors and panics in a
nice and descriptive fashion.
- [Added geographic map support for Tables (data frames).][1187] Tables that
have `latitude`, `longitude`, and optionally `label` columns can now be shown
as points on a map.
- [Added a shortcut for live reloading of visualization files.][1190] This
drastically improves how quickly new visualizations can be tested during their
development. This is _currently_ limited in that, after reloading
visualization definitions, the currently visible visualizations must be
switched to another and switched back to refresh their content. See the [video
podcast about building custom visualizations][podcast-custom-visualizations]
to learn more.
- [Added a visual indicator of the ongoing standard library compilation][1264].
Currently, each time IDE is started, the backend needs to compile the standard
library before it can provide IDE with type information and values. Because of
that, not all functionalities are ready to work directly after starting the
IDE. Now, there is a visible indication of the ongoing background process.
- [Added the ability to reposition visualisations.][1096] There is now an icon
in the visualization action bar that allows dragging the visualization away
from a node. Once the visualization has been moved, another icon appears that
can pin the visualization back to the node.
- [There is now an API to show Version Control System (like Git) status for
nodes][1160].
<br/>![Bug Fixes](/docs/assets/tags/bug_fixes.svg)
#### Visual Environment
- [You can now use the table visualization to display data frames][1181]. Please
note, that large tables will get truncated to 2000 entries. This limitation
will be lifted in future releases.
- [Performance improvements during visual workflow][1067]. Nodes added with the
searcher will have their values automatically assigned to newly generated
variables, which allows the Enso Engine to cache intermediate values and hence
improve visualization performance.
- [Minor documentation rendering fixes][1098]. Fixed cases where text would be
misinterpreted as a tag, added support for new tag types, added support for
more common characters, properly renders overflowing text.
- [Improved handling of projects created with other IDE versions][1214]. The IDE
is now better at dealing with incompatible metadata in files, which stores
node visual position information, the history of chosen searcher suggestions,
etc. This will allow IDE to correctly open projects that were created using a
different IDE version and prevent unnecessary loss of metadata.
- Pressing and holding up and down arrow keys make the list view selection move
continuously.
- The shortcuts to close the application and to toggle the developer tools at
runtime now work on all supported platforms.
- [The loading progress indicator remains visible while IDE initializes][1237].
Previously the loading progress indicator completed too quickly and stopped
spinning before the IDE was ready. Now it stays active, giving a visual
indication that the initialization is still in progress.
- [Fixed visual glitch where a node's text was displayed as white on a white
background][1264]. Most notably this occurred with the output node of a
function generated using the node collapse refactoring.
- Many visual glitches were fixed, including small "pixel-like" artifacts
appearing on the screen.
- [Several parser improvements][1274]. The parser used in the IDE has been
updated to the latest version. This resolves several issues with language
constructs like `import`, lambdas, and parentheses, whereupon typing certain
text the edit could be automatically reverted.
- [The auto-import functionality was improved][1279]. Libraries' `Main` modules
are omitted in expressions inserted by the searcher. For example, the `point`
method of `Geo` library will be displayed as `Geo.point` and will insert
import `Geo` instead of `Geo.Main`.
- Cursors in text editors behave correctly now (they are not affected by scene
pan and zoom). This was possible because of the new multi-camera management
system implemented in EnsoGL.
- [Fixed method names highlighted in pink.][1408] There was a bug introduced
after one of the latest Engine updates, that sent `Unresolved_symbol` types,
which made all methods pink. This is fixed now.
#### EnsoGL (rendering engine)
- A new multi-camera management system, allowing the same shape systems to be
rendered on different layers from different cameras. The implementation
automatically caches the same shape system definitions per scene layer in
order to minimize the amount of WebGL draw calls and hence improve
performance.
- A new depth-ordering mechanism for symbols and shapes. It is now possible to
define depth order dependencies between symbols, shapes, and shape systems.
- Various performance improvements, especially for the text rendering engine.
- Display objects handle visibility correctly now. Display objects are not
visible by default and need to be attached to a visible parent to be shown on
the screen.

# Enso 2.0.0-alpha.1 (2020-01-26)
This is the first release of Enso, a general-purpose programming language and
environment for interactive data processing. It is a tool that spans the entire
stack, going from high-level visualization and communication to the nitty-gritty
of backend services, all in a single language.
<br/>![Release Notes](/docs/assets/tags/release_notes.svg)
#### Anonymous Data Collection
Please note that this release collects anonymous usage data which will be used
to improve Enso and prepare it for a stable release. We will switch to opt-in
data collection in stable version releases. The usage data will not contain your
code (expressions above nodes), however, reported errors may contain brief
snippets of out of context code that specifically leads to the error, like "the
method 'foo' does not exist on Number". The following data will be collected:
