VERSION 1.90.4 (Released 2024-02-22)
-----------------------------------------------------------------------
Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.90.4
Other changes:
- Nav: Fixed SetKeyboardFocusHere() or programmatic tabbing API from not working on
windows with the ImGuiWindowFlags_NoNavInputs flag (regression in 1.90.2, which
among other things broke imgui_memory_editor).
- Menus, Popups: Fixed an issue where hovering a parent-menu upward would
erroneously close the window. (#7325, #7287, #7063)
- Popups: Fixed resizable popup minimum size being too small. Standardized minimum
size logic. (#7329).
- Modals: Temporary changes of ImGuiCol_ModalWindowDimBg are properly handled by
BeginPopupModal(). (#7340)
- Tables: Angled headers: fixed support for multi-line labels. (#6917)
- Tables: Angled headers: various fixes to accurately handle CellPadding changes. (#6917)
- Tables: Angled headers: properly registers horizontal component of angled headers
for auto-resizing of columns. (#6917)
- Tables: Angled headers: fixed TableAngledHeadersRow() incorrect background fill
drawn too low, particularly visible with tables that have no scrolling. (#6917)
- ProgressBar: Fixed a minor tesselation issue when rendering rounded progress bars,
where in some situations the rounded section wouldn't follow regular tesselation rules.
- Debug Tools: Item Picker: Promoted ImGui::DebugStartItemPicker() to public API. (#2673)
- Debug Tools: Item Picker: Menu entry visible in Demo->Tools but greyed out unless
io.ConfigDebugIsDebuggerPresent is set. (#2673)
- Misc: Added optional alpha multiplier parameter to GetColorU32(ImU32) variant.
- Demo: Custom Rendering: better demonstrate PathArcTo(), PathBezierQuadraticCurveTo(),
PathBezierCubicCurveTo(), PathStroke(), PathFillConvex() functions.

VERSION 1.90.3 (Released 2024-02-14)
-----------------------------------------------------------------------
Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.90.3
Breaking changes:
- Backends: SDL2: Removed obsolete ImGui_ImplSDL2_NewFrame(SDL_Window*) signature which
was obsoleted in 1.84. Calling ImGui_ImplSDL2_NewFrame() is fine.
- Backends: Vulkan: Moved RenderPass parameter from ImGui_ImplVulkan_Init() function to
ImGui_ImplVulkan_InitInfo structure. Not required when using dynamic rendering. (#7308) [@shawnhatori]
- Backends: Vulkan: Using dynamic rendering now require filling the PipelineRenderingCreateInfo
structure in ImGui_ImplVulkan_InitInfo, allowing to configure color/depth/stencil formats.
Removed ColorAttachmentFormat field previously provided for dynamic rendering.
(#7166, #6855, #5446, #5037) [@shawnhatori]
Other changes:
- Menus, Popups: Fixed menus and popups with ChildWindow flag erroneously not displaying
a scrollbar when contents is over parent viewport size. (#7287, #7063) [@ZingBallyhoo]
- Backends: SDL2, SDL3: Handle gamepad disconnection + fixed increasing gamepad reference
counter continuously. Added support for multiple simultaneous gamepads.
Added ImGui_ImplSDL2_SetGamepadMode()) function to select whether to automatically pick
first available gamepad, all gamepads, or specific gamepads.
(#3884, #6559, #6890, #7180) [@ocornut, @lethal-guitar, @wn2000, @bog-dan-ro]
- Backends: SDL3: Fixed gamepad handling. (#7180) [@bog-dan-ro]
- Backends: SDLRenderer3: query newly added SDL_RenderViewportSet() to not restore
a wrong viewport if none was initially set.
- Backends: DirectX9: Using RGBA format when allowed by the driver to avoid CPU side
conversion. (#6575) [@Demonese]
- Internals: Fixed ImFileOpen not working before context is created, preventing creation
of a font atlas before main context creation. (#7314, #7315) [@PathogenDavid, @ocornut]
-----------------------------------------------------------------------
VERSION 1.90.2 (Released 2024-02-09)
-----------------------------------------------------------------------
Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.90.2
Breaking changes:
- Commented out ImGuiIO::ImeWindowHandle obsoleted in 1.87 in favor of writing
to 'void* ImGuiViewport::PlatformHandleRaw'.
- Backends: WebGPU: ImGui_ImplWGPU_Init() now takes a ImGui_ImplWGPU_InitInfo structure
instead of variety of parameters, allowing for easier further changes. (#7240)
Other changes:
- Nav: keyboard/gamepad activation mark widgets as held to give better visual feedback.
- Nav: tweak to logic marking navigated item as hovered when using keyboard, allowing
the hover highlight to stay even while another item is activated.
- Nav: Fixed SetKeyboardFocusHere() not working when current nav focus is in different scope,
regression from 1.90.1 related to code scoping Tab presses to local scope. (#7226) [@bratpilz]
- Nav: Fixed pressing Escape while in a child window with _NavFlattened flag. (#7237)
- Nav: Improve handling of Alt key to toggle menu so that key ownership may be claimed on
individual left/right alt key without interfering with the other.
- Nav, Menus: Fixed click on a BeginMenu() followed by right-arrow from making the child menu
reopen and flicker (using ImGuiPopupFlags_NoReopen).
- Nav: ImGuiWindowFlags_NoNavInputs is tested during scoring so NavFlattened windows can use it.
- Popups: OpenPopup(): added ImGuiPopupFlags_NoReopen flag to specifically not close and reopen
a popup when it is already open. (#1497, #1533)
(Note that this differs from specific handling we already have in place for the case of calling
OpenPopup() repeatedly every frame: we already didn't reopen in that specific situation, otherwise
the effect would be very disastrous in term of confusion, as reopening would steal focus).
- Popups: Slight change to popup closing logic (e.g. after focusing another window) which skipped
over popups that are also child windows.
- Combo: Fixed not reusing windows optimally when used inside a popup stack.
- Debug Tools: Metrics: Fixed debug break in SetShortcutRouting() not handling ImGuiMod_Shortcut redirect.
- Debug Tools: Metrics: Improved Monitors and Viewports minimap display. Highlight on hover.
- Debug Tools: Debug Log: Added "Input Routing" logging.
- Debug Tools: Added "nop" to IM_DEBUG_BREAK macro on GCC to work around GDB bug (#7266) [@Peter0x44]
- Backends: Vulkan: Fixed vkAcquireNextImageKHR() validation errors in VulkanSDK 1.3.275 by
allocating one extra semaphore than in-flight frames. (#7236) [@mklefrancois]
- Backends: Vulkan: Fixed vkMapMemory() calls unnecessarily using full buffer size. (#3957)
- Backends: Vulkan: Fixed handling of ImGui_ImplVulkan_InitInfo::MinAllocationSize field. (#7189, #4238)
- Backends: WebGPU: Added ImGui_ImplWGPU_InitInfo::PipelineMultisampleState. (#7240)
- Backends: WebGPU: Filling all WGPUDepthStencilState fields explicitly as a recent Dawn
update stopped setting default values. (#7232) [@GrigoryGraborenko]
- Backends: WebGPU: Fixed pipeline layout leak. (#7245) [@rajveermalviya]
- Backends: OpenGL3: Backup and restore GL_PIXEL_UNPACK_BUFFER. (#7253)
- Internals: Many improvements related to yet unpublicized shortcut routing and input ownership systems.
- Internals: InputText: Added internal helpers to force reload of user-buf when active. (#2890) [@kudaba, @ocornut]
