 Other changes:
 
+- Fonts: added ImFontAtlas::SetFontLoader() to dynamically change font
+  loader at runtime without using internal API. (#8752, #8465)
+- Fonts: for large size fonts, layout/size calculation only load glyphs metrics.
+  Actual glyphs are renderer+packed when used by drawing functions. (#8758, #8465)
+- Fonts: set a maximum font size of 512.0f at ImGui:: API level to reduce
+  edge cases (e.g. out of memory errors). ImDrawList:: API doesn't have the
+  constraint. (#8758)
+- Textures: Fixed support for `#define ImTextureID_Invalid` to non-zero value:
+  ImTextureData() was incorrectly cleared with zeroes. (#8745) [@rachit7645]
+- Demo: Added "Text -> Font Size" demo section. (#8738) [@Demonese]
+- CI: Fixed dllimport/dllexport tests. (#8757) [@AidanSun05]
 - Backends: SDL3: avoid calling SDL_StartTextInput() again if already active.
   (#8727) [@morrazzzz]
 - Backends: OSX: added ImGuiMouseCursor_Wait and ImGuiMouseCursor_Progress

 ## Using Custom Glyph Ranges
 
-🆕 **Since 1.92, with an up to date backend: specifying glyph ranges is necessary, so this is not needed.**
+🆕 **Since 1.92, with an up to date backend: specifying glyph ranges is unnecessary. Therefore this is not really useful any more.**
 
 :rewind: You can use the `ImFontGlyphRangesBuilder` helper to create glyph ranges based on text input. For example: for a game where your script is known, if you can feed your entire script to it and only build the characters the game needs.
