 - Please report any issue!
 
+-----------------------------------------------------------------------
+ VERSION 1.90.6 WIP (In Progress)
+-----------------------------------------------------------------------
+
+Breaking changes:
+
+Other changes:
+
+- Fonts: Fixed font ascent and descent calculation when a font hits exact integer values.
+  It is possible that some prior manual use of ImFontConfig::GlyphOffset may become
+  duplicate with this fix. (#7399, #7404) [@GamingMinds-DanielC]
+- Text, DrawList: Improved handling of long single-line wrapped text. Faster and
+  mitigitate issues with reading vertex indexing limits with 16-bit indices. (#7496, #5720)
+- Backends: SDL3: Fixed text inputs. Re-enable calling SDL_StartTextInput()/SDL_StopTextInput()
+  as SDL3 no longer enables it by default. (#7452, #6306, #6071, #1953) [@Green-Sky]
+
+
+-----------------------------------------------------------------------
+ VERSION 1.90.5 (Released 2024-04-11)
+-----------------------------------------------------------------------
+
+Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.90.5
+
+Breaking changes:
+
+- More formally obsoleted GetKeyIndex() when IMGUI_DISABLE_OBSOLETE_FUNCTIONS is set.
+  It has been unnecessary and a no-op since 1.87 (it returns the same value as passed
+  when used with a 1.87+ backend using io.AddKeyEvent() function). (#4921)
+  - IsKeyPressed(GetKeyIndex(ImGuiKey_XXX)) --> IsKeyPressed(ImGuiKey_XXX)
+- ImDrawList: Merged the radius_x/radius_y parameters in AddEllipse(), AddEllipseFilled()
+  and PathEllipticalArcTo() into a single ImVec2 parameter. Exceptionally, because those
+  functions were added recently in 1.90, we are not adding inline redirection functions.
+  The transition is easy and should affect few users. (#2743, #7417) [@cfillion]
+
+Other changes:
+
+- Windows: Scrollbar visibility decision uses current size when both size and contents
+  size are submitted by API. (#7252)
+- Windows: Double-click to collapse may be disabled via key-ownership mechanism. (#7369)
+- Windows: BeginChild(): Extend outer resize borders to the edges when there are no corner
+  grips. Essentially affects resizable child windows. (#7440, #1710) [@cfillion]
+- Windows: BeginChild(): Resizing logic for child windows evaluates whether per-axis clamping
+  should be applied based on parent scrollbars, not child scrollbars. (#7440, #1710) [@cfillion]
+  Adjust those resizing limits to match window padding rather than inner clipping rectangle.
+- Tables: Fixed auto-width columns when using synced-instances of same table, width of
+  one instance would bleed into next one instead of sharing their widths. (#7218)
+- Tables: Angled headers: fixed border hit box extending beyond when used within
+  non-scrollable tables. (#7416) [@cfillion]
+- Tables: Angled headers: fixed borders not moving back up after TableAngleHeadersRow()
+  stops being called. (#7416) [@cfillion]
+- Tables: Angled headers: rounding header size to nearest integers, fixes some issues
+  when using clipper.
+- Menus, Popups: Fixed an issue where sibling menu popups re-opening in successive
+  frames would erroneously close the window. While it is technically a popup issue
+  it would generally manifest when fast moving the mouse bottom to top in a sub-menu.
+  (#7325, #7287, #7063)
+- ProgressBar: Fixed passing fraction==NaN from leading to a crash. (#7451)

+  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

+- Popups: Fixed resizable popup minimum size being too small. Standardized minimum
+  size logic. (#7329).
+- Modals: Temporary changes of ImGuiCol_ModalWindowDimBg are properly handled by

+- Tables: Angled headers: properly registers horizontal component of angled headers
+  for auto-resizing of columns. (#6917)
+- Tables: Angled headers: fixed TableAngledHeadersRow() incorrect background fill

+

+
+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]
+

+- 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

+-----------------------------------------------------------------------
+
+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.

@@ -53,7 +53,7 @@ All loaded fonts glyphs are rendered into a single texture atlas ahead of time.
 This is often of byproduct of point 3. If you have large number of glyphs or multiple fonts, the texture may become too big for your graphics API. **The typical result of failing to upload a texture is if every glyph or everything appears as empty black or white rectangle.** Mind the fact that some graphics drivers have texture size limitation. If you are building a PC application, mind the fact that your users may use hardware with lower limitations than yours.
 
 Some solutions:
-- You may reduce oversampling, e.g. `font_config.OversampleH = 1`, this will half your texture size for a quality looss.
+- You may reduce oversampling, e.g. `font_config.OversampleH = 1`, this will half your texture size for a quality loss.
   Note that while OversampleH = 2 looks visibly very close to 3 in most situations, with OversampleH = 1 the quality drop will be noticeable. Read about oversampling [here](https://github.com/nothings/stb/blob/master/tests/oversample).
 - Reduce glyphs ranges by calculating them from source localization data.
   You can use the `ImFontGlyphRangesBuilder` for this purpose and rebuilding your atlas between frames when new characters are needed. This will be the biggest win!

 Omar: "I first discovered the IMGUI paradigm at [Q-Games](https://www.q-games.com) where Atman Binstock had dropped his own simple implementation in the codebase, which I spent quite some time improving and thinking about. It turned out that Atman was exposed to the concept directly by working with Casey. When I moved to Media Molecule I rewrote a new library trying to overcome the flaws and limitations of the first one I've worked with. It became this library and since then I have spent an unreasonable amount of time iterating and improving it."
