  VERSION 1.89.3 (In Progress)
 -----------------------------------------------------------------------
 
+All changes:
+
+- Tables: Raised max Columns count from 64 to 512. (#6094, #5305, #4876, #3572)
+  The previous limit was due to using 64-bit integers but we moved to bits-array
+  and tweaked the system enough to ensure no performance loss.
+- Text: Fixed layouting of wrapped-text block skipping successive empty lines,
+  regression from the fix in 1.89.2. (#5720, #5919)
+- Text: Fix clipping of single-character "..." ellipsis (U+2026 or U+0085) when font
+  is scaled. Scaling wasn't taken into account, leading to ellipsis character straying
+  slightly out of its expected boundaries. (#2775)
+- Text: Tweaked rendering of three-dots "..." ellipsis variant. (#2775, #4269)
+- PlotHistogram, PlotLines: Passing negative sizes honor alignment like other widgets.

+For example, the [DirectX11 backend](https://github.com/ocornut/imgui/blob/master/backends/imgui_impl_dx11.cpp) does this:
+```cpp
+// Project scissor/clipping rectangles into framebuffer space
+ImVec2 clip_off = draw_data->DisplayPos;
+ImVec2 clip_min(pcmd->ClipRect.x - clip_off.x, pcmd->ClipRect.y - clip_off.y);
+ImVec2 clip_max(pcmd->ClipRect.z - clip_off.x, pcmd->ClipRect.w - clip_off.y);
+if (clip_max.x <= clip_min.x || clip_max.y <= clip_min.y)
+    continue;
 
+// Apply scissor/clipping rectangle
+const D3D11_RECT r = { (LONG)clip_min.x, (LONG)clip_min.y, (LONG)clip_max.x, (LONG)clip_max.y };
