# 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]
- [Added contextual suggestions to argument dropdowns][4072]. Dropdowns will now
contain suggestions which are based on evaluated data.
#### 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.

# 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
#### Enso Compiler
- [Updated Enso engine to version 0.2.29][engine-0.2.29]. If you're interested

<br/>
# Enso 2.0.0-alpha.15 (2021-09-09)
<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.
[1817]: https://github.com/enso-org/ide/pull/1817
#### Enso Compiler
- [Updated Enso engine to version 0.2.28][1829]. If you're interested in the

#### Visual Environment
- [Improvements to visualization handling][1804]. These improvements are fixing
possible performance issues around attaching and detaching visualizations.
- [GeoMap visualization will ignore points with `null` coordinates][1775]. Now
the presence of such points in the dataset will not break initial map
positioning.
#### Enso Compiler
- [Updated Enso engine to version 0.2.26][1801]. If you're interested in the
enhancements and fixes made to the Enso compiler, you can find their release

- [User Authentication][1653]. Users can sign in to Enso using Google, GitHub or
email accounts.
<br/>![Bug Fixes](/docs/assets/tags/bug_fixes.svg)
#### Visual Environment
- [Fix node selection bug ][1664]. Fix nodes not being deselected correctly in
some circumstances. This would lead to nodes moving too fast when dragged
[1650] or the internal state of the project being inconsistent [1626].

<br/>
# 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,
breadcrumbs and status bar are displayed "above" nodes.

# 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 Compiler

# 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:
- Session length.
- Graph editing events (node create, dele, position change, connect, disconnect,
collapse, edit start, edit end). This will not include any information about
node expressions used.
- Navigation events (camera movement, scope change).
- Visualization events (visualization open, close, switch). This will not
include any information about the displayed data nor the rendered
visualization itself.
- Project management events (project open, close, rename).
- Errors (IDE crashes, WASM panics, Project Manager errors, Language Server
errors, Compiler errors).
- Performance statistics (minimum, maximum, average GUI refresh rate).
