As always, if Browser Actions is already running on your Mac, either wait for the automatic update to pop up on its own (which might take up to 24h), or open the app window, then select “Check for updates …” from the main menu.
Let me know if you come across any issues with the new version, please! 
No longer broken
Sometimes, after reboots, the license check would fail, and a purchase reminder would be shown. (Thanks for the heads-up, David!) I think I found and fixed the root cause for this. If the issue occurs again, please let me know!
Changes
- Browser Actions requires macOS 14 now (before: 13.7).
- Added a proper “What’s New” window.
