 <a name="breaking_changes_1.6.0">[Breaking Changes:](#breaking_changes_1.6.0)</a>
 
-- [core] Context-menu for `tab-bars` requires an `Event` to be passed onto it to perform actions without activating the shell tab-bar [#6965](https://github.com/eclipse-theia/theia/pull/6965)
-  - Removed the logic from `handleContextMenuEvent()` that gives focus to the widget upon opening the context menu, instead functionality added to handle it without activating the widget
-  - This change triggers the context menu for a given shell tab-bar without the need to activate it
-  - While registering a command, `Event` should be passed down, if not passed, then the commands will not work correctly as they no longer rely on the activation of tab-bar
-- [core] Moved `findTitle()` and `findTabBar()` from `common-frontend-contribution.ts` to `application-shell.ts`  [#6965](https://github.com/eclipse-theia/theia/pull/6965)
-- [filesystem] show Linux users a warning when Inotify handles have been exhausted, with link to instructions on how to fix [#8458](https://github.com/eclipse-theia/theia/pull/8458)
+- [core] context-menus for `tab-bars` now require an `Event` to be passed to execute commands without activating the shell `tab-bar` [#6965](https://github.com/eclipse-theia/theia/pull/6965)
+  - Removed logic from `TabBarRenderer.handleContextMenuEvent()` to support triggering context-menus without the need to activate the widget.
+  - When registering a command, `Event` should be passed, else commands will not work correctly as they do no longer rely on the activation of `tab-bars`.
+- [core] refactored `findTitle()` and `findTabBar()` moving them from `common-frontend-contribution.ts` to `application-shell.ts` [#6965](https://github.com/eclipse-theia/theia/pull/6965)
