+    #750)
+  - Fixed background of `boolean` columns when using alternating row colors.
+    (issue #780)
+  - Fixed border arc of components in complex table cell editors. (issue #786)
 - TableHeader: No longer temporary replace header cell renderer while painting.
   This avoids a `StackOverflowError` in case that custom renderer does this too.
