I'm holding off for a few days until people have highlighted the pros and cons.
I updated, and the major con is that
the manual update really sucks. I accidentally wiped my userdata and while I got backups, the magic root manager then failed to reinstall itself without throwing me into a boot loop, and the whole process was just a really frustrating waste of an entire day until I got things back working!
If you don't screw it up though, it works fine as far as I can tell. AudioFX (a sound equalizer) which I manually added/installed as a system up crashes regularly now on this new image, but that might be unrelated to the update, it has always been working unreliably. Other than that, everything works fine and my patchlevel is now September 2018. Edit: I forgot, I also got issues with Wifi, not sure if that's the new image...? I don't rely on that much so I don't really care, but it is a little annoying
But holy crap, updates with a complicated flashing tool only. What is planet computers thinking? I get it for complicated mixed installs, but just the regular plain android in the rooted variant? Come on...
