-- Inputs: added Shortcut() function (w/ routing policies) in public API. (#456, #2637)
-  Added ImGuiInputFlags_RouteFocused, ImGuiInputFlags_RouteGlobalXXX and other routing policies.
-    e.g. ImGui::Shortcut(ImGuiMod_Ctrl | ImGuiKey_C); with default policy:
-    - check that CTRL+C is pressed,
-    - and that current window is in focus stack,
-    - and that no other requests for CTRL+C have been made from deeper locations of the window/item stack.
-- Fixed cases where CTRL+Tab or Modal can occasionally lead to the creation of ImDrawCmd with
-  zero triangles, which would makes the render loop of some backends assert (e.g. Metal with
-  debugging, Allegro). (#4857, #5937)
 - Tables, Nav, Scrolling: fixed scrolling functions and focus tracking with frozen rows and
   frozen columns. Windows now have a better understanding of outer/inner decoration sizes,
   which should later lead us toward more flexible uses of menu/status bars. (#5143, #3692)

   We expect this behavior to be further improved/tweaked. (#3795, #4559) [@ocornut, @folays]
+- InputText: fixed cursor navigation when pressing Up Arrow on the last character of a
+  multiline buffer which doesn't end with a carriage return. (#6000)
 - Text: fixed layouting of wrapped-text block when the last source line is above the
   clipping region. Regression added in 1.89. (#5720, #5919)
 - Misc: added GetItemID() in public API. It is not often expected that you would use this,
   but it is useful for Shortcut() and upcoming owner-aware input functions which wants to
   be implemented with public API.
+- Fonts: imgui_freetype: fixed a packing issue which in some occurrences would prevent large
+  amount of glyphs from being packed correctly. (#5788, #5829)
 - Fonts: added a 'void* UserData' field in ImFontAtlas, as a convenience for use by
   applications using multiple font atlases.
-- Demo: added "Inputs->Shortcut Routing" section.
 - Demo: simplified "Inputs" section, moved contents to Metrics->Inputs.
 - Debug Tools: Metrics: added "Inputs" section, moved from Demo for consistency.

 // (minor and older changes stripped away, please see git history for details)
+//  2023/01/04: fixed a packing issue which in some occurrences would prevent large amount of glyphs from being packed correctly.
 //  2021/08/23: fixed crash when FT_Render_Glyph() fails to render a glyph and returns NULL.
 //  2021/03/05: added ImGuiFreeTypeBuilderFlags_Bitmap to load bitmap glyphs.
 //  2021/03/02: set 'atlas->TexPixelsUseColors = true' to help some backends with deciding of a prefered texture format.
