 Breaking Changes:
 
- - Separator(): fixed a legacy quirk where Separator() was submitting a zero-height
+Other Changes:
+
+- InputText:
+  - InputTextMultiline: fixed an issue processing deactivation logic when an active
+    multi-line edit is clipped due to being out of view.
+  - Fixed a crash when toggling ReadOnly while active. (#9354)
+  - CharFilter callback event sets CursorPos/SelectionStart/SelectionEnd. (#816)
+- Tables:
+  - Fixed issues reporting ideal size to parent window/container: (#9352, #7651)
+    - When both scrollbars are visible but only one of ScrollX/ScrollY was explicitly requested.
+    - When vertical scrollbar was not at the top, the computation was often incorrect.
+- Windows:
+  - Fixed a single-axis auto-resizing feedback loop issue with nested containers
+    and varying scrollbar visibility. (#9352)
+  - Detect and report error when calling End() instead of EndPopup() on a popup. (#9351)
+  - Child windows with only ImGuiChildFlags_AutoResizeY flag keep using the proportional
+    default ItemWidth. (#9355)
+- Multi-Select:

+    items out of view wouldn't be properly selected while scrolling while mouse cursor
+    is hovering outside of selection scope. (#7994, #1861, #6518)
+  - Box-Select: fixed an issue where items out of horizontal view would sometimes lead
+    to incorrect merging of sequential selection requests while also scrolling fast
+    enough to overlap multiple rows during a frame. (#7994, #1861, #6518)
+  - Box-Select: fixed an issue using ImGuiMultiSelectFlags_BoxSelect2d mode in a Table
+    while relying on the TableNextColumn() return value to perform coarse clipping. (#7994)
+  - Box-Select: disabled merging consecutive selection requests as we have no reliable
+    way of detecting if user has submitted all consecutives items without clipping gaps,
+    and ImGuiSelectionUserData is technically opaque storage. (#7994, #1861)
+    (we will probably bring this back as a minor optimization if we have a way to for
+    user to tell us ImGuiSelectionUserData are indices)
+- Fonts:
+  - imgui_freetype: add FreeType headers & compiled version in 'About Dear ImGui' details.
+- Clipper:
+  - Improved error reporting when misusing the clipper inside a table (prioritize
+    reporting the common clipper error over a table sanity check assert). (#9350)
+  - Tweaked assert triggering when first item height measurement fails, and made it
+    a better recoverable error. (#9350)
+- Misc:
+  - Minor optimization: reduce redudant label scanning in common widgets.

+  - Metal: avoid redundant vertex buffer bind in SetupRenderState, which leads

+- Tables:
+  - Allow reordering columns by dragging them in the context menu. (#9312)
+  - Context menu now presents columns in display order. (#9312)
+  - Fixed and clarified the behavior of using `TableSetupScrollFreeze()` with columns>1,
+    and where some of the columns within that range were Hidable.
+    - Before: `TableSetupScrollFreeze(N, 0)`: include the N left-most visible columns as
+              part of the scroll freeze. So if you intentionally hide columns <N, the scroll
+              freeze area would start covering the subsequent/following columns (N+1) etc.
+    - After:  `TableSetupScrollFreeze(N, 0)`: include the N left-most columns (regardless of visibility),
+              as part of the scroll freeze. So if you intentionally hide columns <N, the scroll
+              freeze area will cover less columns.
+    - This is generally more sane and logical.
+  - Fixed dragging a header to reorder outside of visible bounds (due to horizontal scrolling)
+    from losing active id.
+  - Angled Headers: angled section for column being reordered via the regular headers
+    stays highlighted during reordering.
