Version 5.7.6 was just pushed to the Play store. It will be the last release that supports Android 4. All future releases will require Android 5 and above. This change is necessary to maintain what little stability the app has and stay current with Google’s latest libraries.
Specifically, the move to Android 5 means I can get rid of the AlarmManager and start using JobScheduler. It’s a much better way to run the auto refresh of threads. Battery life should go up overall, but at the expense of exact refresh times. Hopefully it ends up being worth it.
