@ -71,6 +71,9 @@ Other changes:
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.
- 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.
- 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),
