  - 2024/08/22 (1.91.1) - moved some functions from ImGuiIO to ImGuiPlatformIO structure:
-                            - io.PlatformOpenInShellFn    -> platform_io.Platform_OpenInShellFn (#7660)
-                            - io.PlatformSetImeDataFn     -> platform_io.Platform_SetImeDataFn

                          some were introduced very recently and often automatically setup by core library and backends, so for those we are exceptionally not maintaining a legacy redirection symbol.
  - 2024/07/25 (1.91.0) - obsoleted GetContentRegionMax(), GetWindowContentRegionMin() and GetWindowContentRegionMax(). (see #7838 on GitHub for more info)
