@@ -43,12 +43,24 @@ Breaking Changes:
 
 - Tabs: Renamed ImGuiTabBarFlags_FittingPolicyResizeDown to ImGuiTabBarFlags_FittingPolicyShrink.
   Kept inline redirection enum (will obsolete). (#261, #351)
+- Backends: SDL_GPU3: changed ImTextureID type from SDL_GPUTextureSamplerBinding* to SDL_GPUTexture*,
+  which is more natural and easier for user to manage. If you need to change the current sampler,
+  you can access the ImGui_ImplSDLGPU3_RenderState struct. (#8866, #8163, #7998, #7988)
 
 Other Changes:
 
+- Fonts: fixed an issue when a font using MergeMode has a reference size
+  specified but the target font doesn't. Usually either all fonts should
+  have a reference size (only required when specifying e.g. GlyphOffset),
+  or none should have a reference size. 
+- Fonts: fixed a crash when changing texture format when using a legacy
+  backend. Most commonly would happen when calling GetTexDataAsRGBA32()
+  then immediately GetTexDataAsAlpha8(). (#8824)
 - Windows: fixed an issue where resizable child windows would emit border
   logic when hidden/non-visible (e.g. when in a docked window that is not
   selected), impacting code not checking for BeginChild() return value. (#8815)
+- Textures: Fixed support for `#define ImTextureID_Invalid` to non-zero value:
+  ImFontAtlas() was incorrectly cleared with zeroes. (#8860, #8745) [@cfillion]
 - Tables: fixed TableGetRowIndex() which never correctly worked when using
   a clipper (it exists for consistency but is almost never used, as it is 
   often more convenient to use index in caller-code, whereas TableGetRowIndex()

 - Tabs: fixed tab bar underline not drawing below scroll buttons, when
   they are enabled (minor regression from 1.90). (#6820, #4859, #5022, #5239)
+- Tabs: made scrolling buttons never keyboard/gamepad navigation candidates.
+- Nav: fixed a bug where GamepadMenu button couldn't toggle between main and
+  menu layers while navigating a Modal window. (#8834)
 - Error Handling: minor improvements to error handling for TableGetSortSpecs()
   and TableSetBgColor() calls. (#1651, #8499)
 - Misc: fixed building with IMGUI_DISABLE_DEBUG_TOOLS only. (#8796)
