The {productname} {release-version} release includes an accompanying release of the **PowerPaste** premium plugin.

**PowerPaste** includes the following fix.

==== Super and subscript text was not properly converted to `sub` or `sup` elements on newer versions of Firefox
// #TINY-14256

Previously, pasting content containing subscript or superscript text from Google Docs into {productname} on Firefox 149 and later did not properly convert the text to semantic `sub` or `sup` elements. Newer versions of Firefox use the `baseline-shift` CSS property instead of the `vertical-align` property for sub and superscript formatting, and PowerPaste did not recognize this property. As a result, the pasted text lost its subscript or superscript formatting.

In {productname} {release-version}, PowerPaste now correctly handles the `baseline-shift` CSS property during paste operations, converting content styled with `baseline-shift: sub` or `baseline-shift: super` into the corresponding `sub` and `sup` elements.
