Because yesterday was a holiday in the US, I cheated a bit. To wit, yesterday's release highlights included:
Fixing wikilinks in infoboxes captions
Gearing up for the opt-in period for our new skin: Fandom Desktop
And the release highlights for today include:
Adding a user preference for collapsed/extended right rail for the new skin
Adding a user preference for a light or dark theme on the new skin
Fixing an issue with closing the QuickTools modal on tablets
Making the "add new section" experience less confusing for editors on talk pages
