Uhm, can't you just use an older installer and restore an auto-backup of your realm? (No Warranties) - I don't synch and never had to do it myself.
New version is just a tad slower. Will be fixed soon.
Agreeing with the QA, especially if the new features are just for the betas
Another recommendation - you are not forced to update, just work offline for some days after an update untill the dust has settled
