Changes (since v1.91.4)

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 enum 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 references:
    • read ocornut/imgui#4921
    • read Changelogs for 1.87 and 1.88. Read API BREAKING CHANGES section of imgui.cpp.
  • 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 was unusually error-prone/misleading since valid keys don't start at 0). Probably use ImGuiKey_NamedKey_BEGIN/ImGuiKey_NamedKey_END instead?
• Fonts: removed const qualifiers from most font functions in prevision for upcoming fonts improvements.

Other changes:

• Selectable: selected Selectable 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.
• InputText: fixed a bug (regression in 1.91.2) where modifying text buffer within a callback would sometimes prevents further appending to the buffer.
• Tabs, Style: made ImGuiCol_TabDimmedSelectedOverline alpha 0 (not visible) in default styles as the current look is not right (but ImGuiCol_TabSelectedOverline stays the same).
• 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.
• Log/Capture: better decorating of BeginMenu() and TabItem() output.
• Log/Capture: a non terminated log ends automatically in the window which called it.
• imgui_freetype: Fixed a crash in build font atlas when using merged fonts and the first font in a merged set has no loaded glyph. (#8081)
• 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)
• Examples: SDL3+Vulkan: Added example. (#8084, #8085)
• Examples: Android+OpenGL: Using ALooper_pollOnce() instead of ALooper_pollAll() which has been deprecated. (#8013) [feather179]

Changes from 1.91.4 to 1.91.5 in the Docking branch:

• Backends: GLFW: added Linux workaround for spurious mouse up events emitted while dragging and creating new viewports. Generally they would be interrupting a dragging operations. (#3158, #7733, #7922) [rokups, ocornut]
• Docking: fixed using ImGuiDockNodeFlags_KeepAliveOnly with DockSpaceOverViewport(): the normally invisible space did erroneously claim mouse hover and could be potentially focused. (#8125) [kcbanner]
