Changelog, minor tweaks. (#2585)

docs/CHANGELOG.txt

@@ -62,6 +62,7 @@ Other Changes:
 - Demo: Added full "Dear ImGui" prefix to the title of "Dear ImGui Demo" and "Dear ImGui Metrics" windows.
 - Backends: Add native Mac clipboard copy/paste default implementation in core library to match what we are
   dealing with Win32, and to facilitate integration in custom engines. (#2546) [@andrewwillmott]
+- Backends: OSX: imgui_impl_osx: Added mouse cursor support. (#2585, #1873) [@actboy168]
 - Examples/Backends: Don't filter characters under 0x10000 before calling io.AddInputCharacter(),
   the filtering is done in io.AddInputCharacter() itself. This is in prevision for fuller Unicode
   support. (#2538, #2541)

 // dear imgui: Platform Binding for OSX / Cocoa

-// [BETA] Beta bindings, not well tested. If you want a portable application, prefer using the Glfw or SDL platform bindings on Mac.
+// [ALPHA] Early bindings, not well tested. If you want a portable application, prefer using the GLFW or SDL platform bindings on Mac.
 
+// Implemented features:
+//  [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
+//  [X] Platform: OSX clipboard is supported within core Dear ImGui (no specific code in this back-end).
 // Issues:
 //  [ ] Platform: Keys are all generally very broken. Best using [event keycode] and not [event characters]..
-// [ ] Platform: Mouse cursor shapes and visibility are not supported (see end of https://github.com/glfw/glfw/issues/427)
