 - Scrollbar: Avoid overlapping the opposite side when window (often a child window) is forcibly too small.
+- Combo: Hide arrow when there's not enough space even for the square button.
+- TabBar: Fixed unfocused tab bar separator color (was using ImGuiCol_Tab, should use ImGuiCol_TabUnfocusedActive).
 - Word-wrapping: Fixed overzealous word-wrapping when glyph edge lands exactly on the limit. Because
   of this, auto-fitting exactly unwrapped text would make it wrap. (fixes initial 1.15 commit, 78645a7d).
 - Scrolling: Added SetScrollHereX(), SetScrollFromPosX() for completeness. (#1580) [@kevreco]
 - Style: Attenuated default opacity of ImGuiCol_Separator in Classic and Light styles.
+- Style: Added style.ColorButtonButton (left/right, defaults to ImGuiDir_Right) to move the color button
+  of ColorEdit3/ColorEdit4 functions to either side of the inputs.
 - Misc: Added IMGUI_DISABLE_METRICS_WINDOW imconfig.h setting to explicitly compile out ShowMetricsWindow().
+- Debug, Metrics: Added "Tools->Item Picker" tool which allow clicking on a widget to break in the debugger
+  within the item code. The tool calls IM_DEBUG_BREAK() which can be redefined in imconfig.h if needed.
 - ImDrawList: Fixed CloneOutput() helper crashing. (#1860) [@gviot]
 - ImDrawList::ChannelsSplit(), ImDrawListSplitter: Fixed an issue with merging draw commands between
   channel 0 and 1. (#2624)
 - ImDrawListSplitter: Fixed memory leak when using low-level split api (was not affecting ImDrawList api,
   also this type was added in 1.71 and not advertised as a public-facing feature).
+- Fonts: binary_to_compressed_c.cpp: Display an error message if failing to open/read the input font file.
 - Backends: SDL2: Added dummy ImGui_ImplSDL2_InitForD3D() function to make D3D support more visible.

 The demo applications are unfortunately not yet DPI aware so expect some blurriness on a 4K screen. For DPI awareness in your application, you can load/reload your font at different scale, and scale your Style with `style.ScaleAllSizes()`.
