@ -69,6 +69,7 @@ Other Changes:
- Checkbox: Added CheckboxFlags() helper with int* type.
- InputText: Fixed updating cursor/selection position when a callback altered the buffer in a way
where the byte count is unchanged but the decoded character count changes. (#3587) [@gqw]
- InputText: Fixed swiching from single to multi-line while preserving same ID.
- Nav: Fixed IsItemFocused() from returning false when Nav highlight is hidden because mouse has moved.
It's essentially been always the case but it doesn't make much sense. Instead we will aim at exposing
feedback and control of keyboard/gamepad navigation highlight and mouse hover disable flag. (#787, #2048)
