@ -34,9 +34,14 @@ HOW TO UPDATE?
 -----------------------------------------------------------------------

 Other Changes:
+
 - ArrowButton: Fixed to honor PushButtonRepeat() setting (and internals' ImGuiItemFlags_ButtonRepeat).
 - ArrowButton: Setup current line text baseline so that ArrowButton() + SameLine() + Text() are aligned properly.
-
+ - Window: Allow menu windows from ignoring the style.WindowMinSize values so short menus are not padded. (#1909)
+ - Misc: Added ImGuiMouseCursor_Hand cursor enum + corresponding software cursor. (#1913, 1914) [@aiekick, @ocornut] 
+ - Misc: Tweaked software mouse cursor offset to match the offset of the corresponding Windows 10 cursors.
+ - Fixed a include build issue for Cygwin in non-POSIX (Win32) mode. (#1917, #1319, #276)
+ - Examples: Win32, Glfw, SDL: Added support for the ImGuiMouseCursor_Hand cursor.
