 <a name="breaking_changes_1.17.0">[Breaking Changes:](#breaking_changes_1.17.0)</a>
 
-- [core] registering toolbar items for commands that explicitly target a `ViewContainer` rather than a child widget may not behave as expected. Such registrations should be made in the `ViewContainer` by overriding the `updateToolbarItems` method and using the `registerToolbarItem` utility. See the modifications to the `scm` and `vsx-registry` packages in the PR for examples. [#9798](https://github.com/eclipse-theia/theia/pull/9798)
+- [core] `ViewContainerPart` methods and properties related to hiding and showing toolbar removed: `toHideToolbar`, `hideToolbar`, `showToolbar`, `toolbarHidden`. `ViewContainerPart` toolbars are now hidden or shown using CSS properties [#9935](https://github.com/eclipse-theia/theia/pull/9935)
+- [core] `handleExpansionToggleDblClickEvent` in `TreeWidget` can no longer be overridden. Instead, `doHandleExpansionToggleDblClickEvent` can be overridden [#9877](https://github.com/eclipse-theia/theia/pull/9877)

-- [core] `SidePanelHandler.addMenu` and `SidePanelHandler.removeMenu` no longer exists, instead added `addBottomMenu` and `addTopMenu` for adding menu, `removeTopMenu` and `removeBottomMenu` for removing menu. 
-  - `SidebarBottomMenu` interface is renamed `SidebarMenu` and handles not only bottom menu's.
