They decided to put some useless push notifications.
And now, when I run the app I get a wonderful message saying that "google play services is not installed, contact the manufacturer" and the app closes.
I don't know why it's required since many apps work just fine without gapps (obviously without push notifications working). As I do not wish to have google play services installed (I use OmniROM + NOGAPPS) I had to revert to the previous version (long live nightly TitaniumBackup jobs).
It worked for a while, then I got the warning "Update available, get it now - or later". The later worked and now it simply said I must update. So I had to uninstall it. I'll use the web interface in firefox (although I don't have the pay to phone contact which I only used a few times a year anyway).
Sigh. I'm wondering how much life AOSP will have left and when it will go (completely) closed source.
