@ -43,6 +43,9 @@ Breaking changes:
Other changes:
- IO: Added GetPlatformIO() and ImGuiPlatformIO, pulled from 'docking' branch, which
is a centralized spot to connect os/platform/renderer related functions.
Clipboard, IME and OpenInShell hooks are moved here. (#7660)
- IO, InputText: fixed an issue where typing text in a InputText() would defer character
processing by one frame, because of the trickling input queue. Reworked interleaved
keys<>char trickling to take account for keys known to input characters. (#7889, #4921, #4858)
