 - ColorEdit4: Alpha default to 255 (instead of 0) when omitted in hex input. (#3973) [@squadack]
+- InputText: Do not filter private unicode codepoints (e.g. icons) when pasted from clipboard. (#4005) [@dougbinks]
 - Popups: Added 'OpenPopup(ImGuiID id)' overload to facilitate calling from nested stacks. (#3993, #331) [@zlash]
 - Backends: SDL: Rework global mouse pos availability check listing supported platforms explicitly,
   effectively fixing mouse access on Raspberry Pi. (#2837, #3950) [@lethal-guitar, @hinxx]
