 Breaking changes:
 
-- ColorEdit, ColorPicker: redesigned how alpha is displayed in the preview square. (#8335, #1578, #346)
+- ColorEdit, ColorPicker: redesigned how alpha is displayed in the preview
+  square. (#8335, #1578, #346)
    - Removed ImGuiColorEditFlags_AlphaPreview (made value 0): it is now the default behavior.
    - Prior to 1.91.8: alpha was made opaque in the preview by default _unless_ using ImGuiColorEditFlags_AlphaPreview.
    - We now display the preview as transparent by default. You can use ImGuiColorEditFlags_AlphaOpaque to use old behavior.

   by introducing a delay. This is a very rarely used UI idiom, but some apps
   use this: e.g. MS Explorer single-click on an icon triggers a rename.
   Generally use with 'delay >= io.MouseDoubleClickTime' + combine with a
-  'io.MouseClickedLastCount == 1' check.
+  'GetMouseClickedCount() == 1' check.
 - Windows: legacy SetWindowFontScale() is properly inherited by nested child
   windows. Note that an upcoming major release should make this obsolete,
   but in the meanwhile it works better now. (#2701, #8138, #1018)
 - Windows, Style: Fixed small rendering issues with menu bar, resize grip and
   scrollbar when using thick border sizes. (#8267, #7887)
 - Windows: Fixed IsItemXXXX() functions not working on append-version of EndChild(). (#8350)
   Also made some of the fields accessible after BeginChild() to match Begin() logic.
+- Error Handling: Recovery from missing EndMenuBar() call. (#1651)
 - Tables, Menus: Fixed using BeginTable() in menu layer (any menu bar). (#8355)
   It previously overrode the current layer back to main layer, which caused an issue
   with MainMenuBar attempted to release focus when leaving the menu layer.
+- Tables, Menus: Fixed tables or child windows submitted inside BeginMainMenuBar()
+  being unable to save their settings, as the main menu bar uses _NoSavedSettings. (#8356)
 - ColorEdit, ColorPicker: Fixed alpha preview broken in 1.91.7. (#8336, #8241). [@PathogenDavid]
 - Tabs, Style: reworked selected overline rendering to better accommodate
   for rounded tabs. Reduced default thickness (style.TabBarOverlineSize),
   increased default rounding (style.TabRounding). (#8334) [@Kian738, @ocornut]
-  styles as the current look is not right (but ImGuiCol_TabSelectedOverline stays the same).
 - Debug Tools: Tweaked font preview.
 - ImDrawList: texture baked storage for thick line reduced from ~64x64 to ~32x32. (#3245)
 - Fonts: IndexLookup[] table hold 16-bit values even in ImWchar32 mode,

 - Fonts: OversampleH/OversampleV defaults to 0 for automatic selection.
