This is so far the most stable and most tested release. All previous versions incorporate bugs, some of them critical. I'm sorry about the trouble.
Update
F-Droid finally released this version! Download the official APK, to get the official app, which you could also install through F-Droid.
Due to incompatible signatures, you cannot use the APK from this release interchangeably with the official F-Droid release. However, you can create a backup in the official APK, uninstall it, then you install this version and import the backup.
Then, when an even newer version is released on F-Droid, you can repeat the above process and stay with the F-Droid APK.
Again, sorry about the trouble.
