                             - if you have trouble updating a very old codebase using legacy backend-specific key codes: consider updating to 1.91.4 first, then #define IMGUI_DISABLE_OBSOLETE_KEYIO, then update to latest.
                        - obsoleted ImGuiKey_COUNT (it is unusually error-prone/misleading since valid keys don't start at 0). probably use ImGuiKey_NamedKey_BEGIN/ImGuiKey_NamedKey_END?
+                       - fonts: removed const qualifiers from most font functions in prevision for upcoming font improvements.
  - 2024/10/18 (1.91.4) - renamed ImGuiCol_NavHighlight to ImGuiCol_NavCursor (for consistency with newly exposed and reworked features). Kept inline redirection enum (will obsolete).
  - 2024/10/14 (1.91.4) - moved ImGuiConfigFlags_NavEnableSetMousePos to standalone io.ConfigNavMoveSetMousePos bool.
                          moved ImGuiConfigFlags_NavNoCaptureKeyboard to standalone io.ConfigNavCaptureKeyboard bool (note the inverted value!).
