@@ -41,20 +41,105 @@ HOW TO UPDATE?
 
 Breaking changes:
 
+- Image: removed 'tint_col' and 'border_col' parameter from Image() function. (#8131, #8238)
+  - Old function signature:
+      void Image      (ImTextureID tex_id, ImVec2 image_size, ImVec2 uv0 = (0,0), ImVec2 uv1 = (1,1), ImVec4 tint_col = (1,1,1,1), ImVec4 border_col = (0,0,0,0));
+  - New function signatures:
+      void Image      (ImTextureID tex_id, ImVec2 image_size, ImVec2 uv0 = (0,0), ImVec2 uv1 = (1,1));
+      void ImageWithBg(ImTextureID tex_id, ImVec2 image_size, ImVec2 uv0 = (0,0), ImVec2 uv1 = (1,1), ImVec4 bg_col = (0,0,0,0), ImVec4 tint_col = (1,1,1,1));
+  - TL;DR: 'border_col' had misleading side-effect on layout, 'bg_col' was missing, parameter order couldn't be consistent with ImageButton().
+  - New behavior always use ImGuiCol_Border color + style.ImageBorderSize / ImGuiStyleVar_ImageBorderSize.
+  - Old behavior altered border size (and therefore layout) based on border color's
+    alpha, which caused variety of problems.
+  - Old behavior used a fixed value of 1.0f for border size which was not tweakable.
+  - Kept legacy signature (will obsolete), which mimics the old behavior,
+    but uses Max(1.0f, style.ImageBorderSize) when border_col is specified.
+  - Added ImageWithBg() function which has both 'bg_col' (which was missing) and 'tint_col'.
+    It was impossible to add 'bg_col' to Image() with a parameter order consistent with
+    other functions, so we decided to remove 'tint_col' and introduce ImageWithBg().
 - Renamed ImFontConfig::GlyphExtraSpacing.x option to GlyphExtraAdvanceX. (#242)
+- Renamed style.TabMinWidthForCloseButton to style.TabCloseButtonMinWidthUnselected.
+- Backends: Vulkan: Added 'uint32_t api_version' argument to ImGui_ImplVulkan_LoadFunctions().
+  Note that it was also added to ImGui_ImplVulkan_InitInfo but for the later it is optional.
+  (#8326, #8365, #8400)
 
 Other changes:
 
 - Fixed IsItemDeactivatedAfterEdit() signal being broken for Checkbox(),
   RadioButton(), Selectable(). Regression from 2025/01/13. (#8370)
+- Windows: Fixed an issue where BeginChild() inside a collapsed Begin()
+  wouldn't inherit the SkipItems flag, resulting in missing coarse clipping
+  opportunity for code not checking the BeginChild() return value.
+- Windows, Style: Added style.WindowBorderHoverPadding setting to configure
+  inner/outer padding applied to hit-testing of windows borders and detection
+  of hovered window.
+- InputText: Allow CTRL+Shift+Z to redo even outside of OSX. (#8389) [@tanksdude]
 - InputTextWithHint(): Fixed buffer-overflow (luckily often with no visible effect)
   when a user callback modified the buffer contents in a way that altered the
   visibility of the preview/hint buffer. (#8368) [@m9710797, @ocornut]
 - Scrollbar: Rework logic that fades-out scrollbar when it becomes too small,
   which amusingly made it disappear when using very big font/frame size.
+- Tables: fixed calling SetNextWindowScroll() on clipped scrolling table
+  to not leak the value into a subsequent window. (#8196)
+- Tables: fixed an issue where Columns Visible/Width state wouldn't be correctly
+  restored when hot-reloading .ini state. (#7934)
+- Tables: tamed some .ini settings optimizations to more accurately allow
+  overwriting/hot-reloading settings in more situations. (#7934)
+- Tables, Error Handling: Recovery from invalid index in TableSetColumnIndex(). (#1651)
+- Image: Added ImageWithBg() variant with bg color and tint color. (#8131, #8238)
+- Image, Style: Added style.ImageBorderSize, ImGuiStyleVar_ImageBorderSize. (#8131, #8238)
+- Selectable: Fixed horizontal label alignment with SelectableTextAlign.x > 0 and
+  specifying a selectable size. (#8338)
+- Tabs, Style: made the Close Button of selected tabs always visible by default,
+  without requiring to hover the tab. (#8387)
+  - Added style.TabCloseButtonMinWidthSelected/TabCloseButtonMinWidthUnselected settings
+    to configure visibility of the Close Button for selected and unselected tabs.
+    (-1: always visible. 0.0f: visible when hovered. >0.0f: visible when hovered if minimum width)
+  - Default for selected tabs: TabCloseButtonMinWidthSelected = -1.0f (always visible)
+  - Default for unselected tabs: TabCloseButtonMinWidthUnselected = 0.0f (visible when hovered)
+- Tabs: fixed middle-mouse-button to close tab not checking that close button
+  is hovered, merely it's visibility. (#8399, #8387) [@nicovanbentum]
+- TextLink(), TextLinkOpenURL(): fixed honoring text baseline alignment.
+  (#8451, #7660) [@achabense]
+- TextLinkOpenURL(): fixed default Win32 io.PlatformOpenInShellFn handler to
+  handle UTF-8 regardless of system regional settings. (#7660) [@achabense]
+- Disabled: Fixed an issue restoring Alpha in EndDisabled() when using nested
+  BeginDisabled() calls with PushStyleVar(ImGuiStyleVar_DisabledAlpha) within. (#8454, #7640)
+- Clipper: Fixed an issue where passing an out of bound index to IncludeItemByIndex()
+  could incorrectly offset the final cursor, even if that index was not iterated through.
+  One case where it would manifest was calling Combo() with an out of range index. (#8450)
+- Debug Tools: Added io.ConfigDebugHighlightIdConflictsShowItemPicker (defaults to true)
+  to allow disabled Item Picker suggestion in user facing builds. (#7961, #7669)
+- Misc: Added ImGuiMouseCursor_Wait and ImGuiMouseCursor_Progress mouse cursors
+  (busy/wait/hourglass shape, with or without an arrow cursor).
+- Demo: Reorganized "Widgets" section to be alphabetically ordered and split in more functions.
+- Demo: Combos: demonstrate a very simple way to add a filter to a combo,
+  by showing the filter inside the combo contents. (#718)
+- Backends: GLFW: Fixed clipboard handler assertion when using GLFW <= 3.2.1 compiled
+  with asserts enabled. (#8452)
+- Backends: SDL2, SDL3: Using SDL_OpenURL() in platform_io.Platform_OpenInShellFn
+  handler. (#7660) [@achabense]
+- Backends: SDL2, SDL3, Win32, Allegro5: Added support for ImGuiMouseCursor_Wait
+  and ImGuiMouseCursor_Progress cursors.
+- Backends: SDL2, SDL3: Avoid calling SDL_GetGlobalMouseState() when mouse is in
+  relative mode. (#8425, #8407) [@TheMode]
+- Backends: SDL2, SDL3: Only start SDL_CaptureMouse() when mouse is being dragged,
+  to mitigate issues with e.g. Linux debuggers not claiming capture back. (#6410, #3650)
+- Backends: OpenGL3: Lazily reinitialize embedded GL loader for when calling backend
+  from e.g. other DLL boundaries. (#8406)
+- Backends: DirectX12: Fixed an issue where pre-1.91.5 legacy ImGui_ImplDX12_Init()
+  signature started breaking in 1.91.8 due to missing command queue. (#8429)
 - Backends: Metal: Fixed a crash on application resources. (#8367, #7419) [@anszom]
-- Backends: WebGPU: Fix for DAWN API rename WGPUProgrammableStageDescriptor -> WGPUComputeState.

+                            - TL;DR: 'border_col' had misleading side-effect on layout, 'bg_col' was missing, parameter order couldn't be consistent with ImageButton().
+                            - new behavior always use ImGuiCol_Border color + style.ImageBorderSize / ImGuiStyleVar_ImageBorderSize.
+                            - old behavior altered border size (and therefore layout) based on border color's alpha, which caused variety of problems + old behavior a fixed 1.0f for border size which was not tweakable.
+                            - kept legacy signature (will obsolete), which mimics the old behavior,  but uses Max(1.0f, style.ImageBorderSize) when border_col is specified.
+                            - added ImageWithBg() function which has both 'bg_col' (which was missing) and 'tint_col'. It was impossible to add 'bg_col' to Image() with a parameter order consistent with other functions, so we decided to remove 'tint_col' and introduce ImageWithBg().
  - 2025/02/06 (1.91.9) - renamed ImFontConfig::GlyphExtraSpacing.x to ImFontConfig::GlyphExtraAdvanceX.
  - 2025/01/22 (1.91.8) - removed ImGuiColorEditFlags_AlphaPreview (made value 0): it is now the default behavior.
                          prior to 1.91.8: alpha was made opaque in the preview by default _unless_ using ImGuiColorEditFlags_AlphaPreview. We now display the preview as transparent by default. You can use ImGuiColorEditFlags_AlphaOpaque to use old behavior.
