# Important Notes
- The PR assigns icon names to four items in the standard library, but only three of them are shown in the Component Browser because of [a parsing bug in the Engine](https://www.pivotaltracker.com/story/show/182781673).
- Icon names are assigned only to four items in the standard library because only two currently predefined icons match entries in the currently defined Virtual Component Groups. Adjusting the definitions of icons and Virtual Component Groups is covered by [a different task](https://www.pivotaltracker.com/story/show/182584311).
- A bug in the documentation of the Enso protocol message `DocSection` is fixed. A `text` field in the `Tag` interface is renamed to `body` (this is the field name used in Engine).
Changelog:
- Describe the `EditKind` optional parameter that allows enabling engine-side optimizations, like value updates
- Describe the `text/openBuffer` message required for the lazy visualizations feature
Changelog:
- add: component groups to package descriptions
- add: `executionContext/getComponentGroups` method that returns component groups of libraries that are currently loaded
- doc: cleanup unimplemented undo/redo commands
- refactor: internal component groups datatype
Changelog:
- feat: during the boot, prune outdated modules
from the suggestions database
- feat: when renaming the project, send updates
about changed records in the database
- refactor: remove deprecated
executionContext/expressionValuesComputed
notification
PR adds the new executionContext/expressionUpdates
API that replaces executionContext/expressionValueUpdates
notification, and in the future will be extended to support
the dataflow errors.
A bunch of improvements to the suggestions
system. Suggestions are extracted to the tree data
structure. The tree allows producing better diffs
between the file versions. And better diffs reduce
the number of updates that are sent to the IDE
after a file change, and consequently fix the
issue when the runtime type got overwritten with
the compile-time type.
Add new `executionContext/executionStatus`
notification returning a list of diagnostic
messages containing localized (linked to the
location in the code) information about
compilation errors and warnings, as well as
runtime errors with stack traces.
