   codepath that preserve last contents size when collapsed, resulting in
   programmatically uncollapsing auto-sizing windows having them flicker size
   for a frame. (#7691) [@achabense]
+- Windows: loosened code to allow hovering of resize grips, borders, and table
+  borders while hovering a sibling child window, so that the code in master matches
+  one in docking (they accidentally diverged). (#8554)
+- TreeNode: added flags to draw tree hierarchy outlines linking parent
+  and tree nodes: (#2920)
+  - ImGuiTreeNodeFlags_DrawLinesNone: No lines drawn.
+  - ImGuiTreeNodeFlags_DrawLinesFull: Horizontal lines to child nodes. Vertical line drawn down to TreePop() position: cover full contents.
+  - ImGuiTreeNodeFlags_DrawLinesToNodes: Horizontal lines to child nodes. Vertical line drawn down to bottom-most child node.
+  - Added style.TreeLinesFlags which stores the default setting, 
+    which may be overriden in individual TreeNode() calls.
+  - Added style.TreeLinesSize (default to 1.0f).
+  - Added ImGuiCol_TreeLines (in default style this is the same as ImGuiCol_Border).
+  - The feature adds a little cost as extra data needs to be stored.
 - Nav: fixed assertion when holding gamepad FaceLeft/West button to open
   CTRL+Tab windowing + pressing a keyboard key. (#8525)
 - Error Handling: added better error report and recovery for extraneous
   EndPopup() call. (#1651, #8499)
+- Fonts: word-wrapping code handle ideographic comma & full stop (U+3001, U+3002). (#8540)
+- Fonts: fixed CalcWordWrapPositionA() fallback when width is too small to wrap:
+  would use a +1 offset instead of advancing to the next UTF-8 codepoint. (#8540)
 - Style, InputText: added ImGuiCol_InputTextCursor to configure color of
   the InputText cursor/caret. (#7031)
 - Misc: added extra operators to ImVec4 in IMGUI_DEFINE_MATH_OPERATORS block. (#8510) [@gan74]
