Changelog available here[github.com].

New versions may take a while to be available in the Chrome / Firefox stores. They should be updated automatically in 24 hours, at most.

If you're a userscript user, it will not auto update, because the script is no longer located in the repository. Now the script will be handled by releases, so you'll have to go here[github.com] and click on userscript.user.js to force an update. Also, I think you'll have to do this every time there's an update, because it looks like Tampermonkey isn't able to detect an update by using the userscript.meta.js file from the release.
