@ -88,6 +88,8 @@ Other changes:
- CollapsingHeader/TreeNode: Fixed text padding when using _Framed+_Leaf flags. (#6549) [@BobbyAnguelov]
- InputText: Fixed not returning true when buffer is cleared while using the
ImGuiInputTextFlags_EscapeClearsAll flag. (#5688, #2620)
- InputText: ImGuiInputTextCallbackData::InsertChars() accept (NULL,NULL) range, in order to conform
to common idioms (e.g. passing .data(), .data() + .size() from a null string). (#6565, #6566, #3615)
- Combo: Made simple/legacy Combo() function not returns true when picking already selected item.
This is consistent with other widgets. If you need something else, you can use BeginCombo(). (#1182)
- Clipper: Rework inner logic to allow functioning with a zero-clear constructor.
