 -----------------------------------------------------------------------
 
+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.
