 {productname} {release-version} also includes the following bug fix<es>:
 
-// === <TINY-vwxyz 1 changelog entry>
-// #TINY-vwxyz1
+=== The HTML schema did not treat `colgroup` or `col` elements as block elements.
+// #TINY-12092
 
-// CCFR here.
+In previous versions of {productname}, whitespace between `<colgroup>` and `<col>` tags was not removed by {productname}'s HTML schema. This behavior caused the editor to preserve unnecessary whitespace characters in the table markup.
+
+This issue has been resolved in `{release-version}`. Both `colgroup` and `col` elements are now treated as block-level elements, ensuring that extraneous whitespace is stripped from these areas. As a result, the editor now produces cleaner and more concise table markup.
