   Courtesy of legacy untangling commity: [@rokups, @ocornut, @thedmd]
 - ImDrawList: clarified that PathArcTo()/PathArcToFast() won't render with radius < 0.0f. Previously it sorts
   of accidentally worked but would lead to counter-clockwise paths which and have an effect on anti-aliasing.
+- InputText: renamed ImGuiInputTextFlags_AlwaysInsertMode to ImGuiInputTextFlags_AlwaysOverwrite, old name was an
+  incorrect description of behavior. Was ostly used by memory editor. Kept inline redirection function. (#2863)
 - Moved 'misc/natvis/imgui.natvis' to 'misc/debuggers/imgui.natvis' as we will provide scripts for other debuggers.
 - Style: renamed rarely used style.CircleSegmentMaxError (old default = 1.60f)
   to style.CircleTessellationMaxError (new default = 0.30f) as its meaning changed. (#3808) [@thedmd]

  - input text: access public fields via a non-callback API e.g. InputTextGetState("xxx") that may return NULL if not active.
  - input text: flag to disable live update of the user buffer (also applies to float/int text input) (#701)
  - input text: hover tooltip could show unclamped text
+ - input text: support for INSERT key to toggle overwrite mode. currently disabled because stb_textedit behavior is unsatisfactory on multi-line. (#2863)
  - input text: option to Tab after an Enter validation.
  - input text: add ImGuiInputTextFlags_EnterToApply? (off #218)
  - input text: easier ways to update buffer (from source char*) while owned. preserve some sort of cursor position for multi-line text.
