Hmm I don't really love the update! Not that I am really unlucky, there a lot of improvements. Update worked fine most things work smooth.
But I have formated my SD-Card with BTRFS and shared space with android. That doesn't work anymore. Not that I haven't expected that. But I don't really understand, why there is still no official solution for that problem. I hope that they will have a solution when they release the tablet and sailfish OS 2.0

So all in all Update is nice, but I don't want to tinker after every update.
