   from the tested windows when combined with _ChildWindows.
 - InputTextMultiline: Fixed label size not being included into window contents rect unless
   the whole widget is clipped.
-- InputText: Allow cancelling/validating input with gamepad nav events to facilitate undoing
-  an accidental press on NavInput (Triangle button on PS4/PS5) without a wired keyboard. (#2321)
+- InputText: Allow activating/cancelling/validating input with gamepad nav events. (#2321, #4552)
 - TextUnformatted: Accept null ranges including (NULL,NULL) without asserting, in order to conform
   to common idioms (e.g. passing .data(), .data() + .size() from a null string). (#3615)
+- Disabled: Added assert guard for mismatching BeginDisabled()/EndDisabled() blocks. (#211)
 - Nav: Fixed toggling menu layer with Alt or exiting menu layer with Esc not moving mouse when
   the NavEnableSetMousePos config flag is set.

   the arrow section of TreeNode(), the +/- buttons of InputInt()/InputFloat(), Selectable() with
   ImGuiSelectableFlags_SelectOnRelease. More generally: any direct use of ButtonBehavior() with
   the PressedOnClick/PressedOnDoubleClick/PressedOnRelease button policy.
+- Nav: Fixed an issue with losing focus on docked windows when pressing Alt while keyboard navigation
+  is disabled. (#4547, #4439) [@PathogenDavid]
+- TreePush(): removed unnecessary/inconsistent legacy behavior where passing a NULL value to
+  the TreePush(const char*) and TreePush(const void*) functions would use an hardcoded replacement.
+  The only situation where that change would make a meaningful difference is TreePush((const char*)NULL)
+  (_explicitely_ casting a null pointer to const char*), which is unlikely and will now crash.
+  You may replace it with anything else.
+- ColorEdit4: Fixed not being able to change hue when saturation is 0. (#4014) [@rokups]
+- ColorEdit4: Fixed hue resetting to 0 when it is set to 255. [@rokups]
+- ColorEdit4: Fixed hue value jitter when source color is stored as RGB in 32-bit integer and perform
+  RGB<>HSV round trips every frames. [@rokups]
+- ColorPicker4: Fixed picker being unable to select exact 1.0f color when dragging toward the edges
+  of the SV square (previously picked 0.999989986f). (#3517) [@rokups]
 - Menus: Fixed vertical alignments of MenuItem() calls within a menu bar. (broken in 1.84). (#4538)
 - Menus: Adjust closing logic to accomodate for varying font size and dpi.
 - Menus: Fixed crash when navigating left inside a child window inside a sub-menu. (#4510).
 - Drag and Drop: Fixed using BeginDragDropSource() inside a BeginChild() that returned false. (#4515)
 - PlotHistogram: Fixed zero-line position when manually specifying min<0 and max>0. (#4349) [@filippocrocchini]
+- Misc: Added asserts for missing PopItemFlag() calls.
 - IO: Added 'io.WantCaptureMouseUnlessPopupClose' alternative to `io.WantCaptureMouse'. (#4480)
   This allows apps to receive the click on void when that click is used to close popup (by default,
   clicking on a void when a popup is open will close the popup but not release io.WantCaptureMouse).
 - Fonts: imgui_freetype: Fixed crash when FT_Render_Glyph() fails to render a glyph and returns NULL
   (which apparently happens with Freetype 2.11). (#4394, #4145?).
 - Fonts: Fixed ImFontAtlas::ClearInputData() marking atlas as not built. (#4455, #3487)
+- Backends: Added more implicit asserts to detect invalid/redundant calls to Shutdown functions. (#4562)
 - Backends: OpenGL3: Fixed our custom GL loader conflicting with user using GL3W. (#4445) [@rokups]
 - Backends: WebGPU: Fixed for latest specs. (#4472) [@Kangz]
+- Backends: SDL_Renderer: Added SDL_Renderer backend compatible with upcoming SDL 2.0.18. (#3926) [@1bsyl]
 - Backends: Metal: Fixed a crash when clipping rect larger than framebuffer is submitted via
   a direct unclipped PushClipRect() call. (#4464)
+- Backends: OSX: Use mach_absolute_time as CFAbsoluteTimeGetCurrent can jump backwards. (#4557, #4563) [@lfnoise]
 - Backends: All renderers: Normalize clipping rect handling across backends. (#4464)
+- Examples: Added SDL + SDL_Renderer example in "examples/example_sdl_sdlrenderer/" folder. (#3926) [@1bsyl]
