Not only is the new stable there, cketti has been posting all of the betas leading up to this on F-Droid for quite awhile. :) You have to manually look once in awhile in the F-Droid client for newer beta builds to opt into using.
You can enable the 'Unstable updates' option in F-Droid's settings to receive notifications for new beta versions to avoid having to check manually. The downside is that you'll receive these updates for all apps, so be sure to check if a new version is a beta version for apps that you want to keep on stable versions.
