- Added Horizontal Rule (HR) editing shortcut and dismissible “Paste as Text” notice in TinyMCE.
- Selective Refresh support is enabled for core themes titles and taglines, which allows shift-click to focus on controls and PHP filters to apply in the preview.
- Resolved a fatal error on image upload when ImageMagick could not complete stripping meta during resize (#33642).
