 Breaking changes:
 
+- Commented out pre-1.87 IO system (equivalent to using IMGUI_DISABLE_OBSOLETE_KEYIO or IMGUI_DISABLE_OBSOLETE_FUNCTIONS before).
+  - io.KeyMap[] and io.KeysDown[] are removed (obsoleted February 2022).
+  - io.NavInputs[] and ImGuiNavInput are removed (obsoleted July 2022).
+  - Pre-1.87 backends are not supported:
+    - backends need to call io.AddKeyEvent(), io.AddMouseEvent() instead of writing to io.KeysDown[], io.MouseDown[] fields.
+    - backends need to call io.AddKeyAnalogEvent() for gamepad values instead of writing to io.NavInputs[] fields.
+  - For more reference:
+    - read 1.87 and 1.88 part of this section or read Changelog for 1.87 and 1.88.
+    - read https://github.com/ocornut/imgui/issues/4921
+  - 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?
+
 Other changes:
 
 - Selectable: selected Selectables use ImGuiCol_Header instead of an arbitrary lerp
   between _Header and _HeaderHovered which was introduced v1.91 (#8106, #1861)
+- Buttons: using ImGuiItemFlags_ButtonRepeat makes default button behavior use
+  PressedOnClick instead of PressedOnClickRelease when unspecified.
+- Fonts: removed const qualifiers from most font functions.
+- InputText: fixed a bug (regression in 1.91.2) where modifying text buffer within
+  a callback would sometimes prevents further appending to the buffer.
+- Log/Capture: better decorating of BeginMenu() and TabItem() output.
+- Log/Capture: a non terminated log ends automatically in the window which called it.
+- Log/Capture: added experimental io.ConfigWindowsCopyContentsWithCtrlC option to
+  automatically copy window contents into clipboard using CTRL+C. This is experimental
+  because (1) it currently breaks on nested Begin/End, (2) text output quality varies,
+  and (3) text output comes in submission order rather than spatial order.
 - Backends: DX12: Unmap() call specify written range. The range is informational and
   may be used by debug tools.
 - Backends: SDL2: Replace SDL_Vulkan_GetDrawableSize() forward declaration with the 
   actual include. (#8095, #7967, #3190) [@sev-] 
 - Backends: SDL2, SDL3: SDL_EVENT_MOUSE_WHEEL event doesn't require dividing 
   by 100.0f on Emscripten target. (#4019, #6096, #1463)

 Breaking Changes:
 
-Work on dear imgui has been gradually resuming. It means that fixes and new features should be tackled at a faster rate than last year. However, in order to move forward with the library and get rid of some cruft, I have taken the liberty to be a little bit more aggressive than usual with API breaking changes. Read the details below and search for those names in your code! In the grand scheme of things, those changes are small and should not affect everyone, but this is technically our most aggressive release so far in term of API breakage. If you want to be extra forward-facing, you can enable `#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS` in your imconfig.h to disable the obsolete names/redirection.

 - Marked the weird `IMGUI_ONCE_UPON_A_FRAME` helper macro as obsolete. Prefer using the more explicit `ImGuiOnceUponAFrame`.
-- Changed `ColorEdit4(const char* label, float col[4], bool show_alpha = true)` signature to `ColorEdit4(const char* label, float col[4], ImGuiColorEditFlags flags = 0)`, where flags 0x01 is a safe no-op (hello dodgy backward compatibility!).

There are a bunch of available flags, check the Demo window and comment for `ImGuiColorEditFlags_`. Some of the options it supports are: two color picker types (hue bar + sat/val rectangle, hue wheel + rotating sat/val triangle), display as u8 or float, lifting 0.0..1.0 constraints (currently rgba only), context menus, alpha bar, background checkerboard options, preview tooltip, basic revert. For simple use, calling the existing `ColorEdit4()` function as you did before will be enough, as you can now open the color picker from there.
