<a name="breaking_changes_1.21.0">[Breaking Changes:](#breaking_changes_1.21.0)</a>
- [core/shared] removed `vscode-languageserver-types`; use `vscode-languageserver-protocol` instead [#10500](https://github.com/eclipse-theia/theia/pull/10500)
- [core] added `SelectionService` as a constructor argument of `TabBarRenderer` [#10394](https://github.com/eclipse-theia/theia/pull/10394)
- [core] removed deprecated `activeChanged` signal emitter in favor of `onDidChangeActiveWidget` [#10515](https://github.com/eclipse-theia/theia/pull/10515)
- [core] removed deprecated `currentChanged` signal emitter in favor of `onDidChangeCurrentWidget` [#10515](https://github.com/eclipse-theia/theia/pull/10515)
- [core] updated `WindowService` interface considerably [#10379](https://github.com/eclipse-theia/theia/pull/10379)
- remove `canUnload(): boolean`- it's replaced by `isSafeToShutDown(): Promise<boolean>` to allow asynchronous handling in Electron.
- add `isSafeToShutDown()` - replaces `canUnload()`.
- add `setSafeToShutDown()` - ensures that next close event will not be prevented.
- add `reload()` - to allow different handling in Electron and browser.
- [editor] moved the utilities for creating and manipulating dynamic stylesheets from `editor-decoration-style.ts` to `decoration-style.ts` in `core`.
Each namespace now has its independent stylesheet. Only one rule should exist for a given selector in the provided stylesheet. [#10441](https://github.com/eclipse-theia/theia/pull/10441)
- [plugin] changed return type of `WebviewThemeDataProvider.getActiveTheme()` to `Theme` instead of `WebviewThemeType` [#10493](https://github.com/eclipse-theia/theia/pull/10493)
- [plugin] removed the application prop `resolveSystemPlugins`, builtin plugins should now be resolved at build time [#10353](https://github.com/eclipse-theia/theia/pull/10353)
- [plugin] renamed `WebviewThemeData.activeTheme` to `activeThemeType` [#10493](https://github.com/eclipse-theia/theia/pull/10493)
- [preferences] removed `PreferenceProvider#pendingChanges` field. It was previously set unreliably and caused race conditions.
If a `PreferenceProvider` needs a mechanism for deferring the resolution of `PreferenceProvider#setPreference`, it should implement its own system.
See PR for example implementation in `AbstractResourcePreferenceProvider`. [#7775](https://github.com/eclipse-theia/theia/pull/7775)
- [terminal] removed deprecated `activateTerminal` method in favor of `open`. [#10529](https://github.com/eclipse-theia/theia/pull/10529)
- [webpack] Source maps for the frontend renamed from `webpack://[namespace]/[resource-filename]...` to `webpack:///[resource-path]?[loaders]` where `resource-path` is the path to
the file relative to your application package's root [#10480](https://github.com/eclipse-theia/theia/pull/10480)

<a name="notable_changes_1.16.0">[Notable Changes:](#notable_changes_1.16.0)</a>
- [application-manager] defines a new range for `webpack` (`^5.36.2 <5.47.0`). `webpack@5.47.0` depends on `webpack-sources@^3.0.1` but this new version produces bogus bundles in Theia applications. The fix works by constraining the `webpack` version range to not pull newer versions for Theia v1.16.0 meaning clients creating Theia applications will not be affected by the bundling failures caused by the new dependency. The bogus library will most likely be fixed before next release (v1.17.0) so we'll need to update the `webpack` range back to pull newer versions again (bug/performance/security updates).
<a name="breaking_changes_1.16.0">[Breaking Changes:](#breaking_changes_1.16.0)</a>
- [callhierarchy] `CurrentEditorAccess` is deprecated. Use the version implemented in the `editor` package instead. The services in `call-hierarchy` that previously used the local `CurrentEditorAccess` no longer do [#9681](https://github.com/eclipse-theia/theia/pull/9681)

- [monaco] upgraded to monaco 0.23.0 including replacement of `quickOpen` API (0.20.x) with `quickInput` API (0.23.x) [#9154](https://github.com/eclipse-theia/theia/pull/9154)
- [workspace] `WorkspaceCommandContribution.addFolderToWorkspace` no longer accepts `undefined`. `WorkspaceService.addRoot` now accepts a `URI` or a `URI[]` [#9684](https://github.com/eclipse-theia/theia/pull/9684)
