Get excited - 5.2 is finally here! 
If you have zypper ref; zypper duped recently, you’ll have the Verdanditeam GUI updater available under ‘Settings → Sailfish OS updates’ and should be able to use that to update your system from 5.1.0.11 to 5.2.0.22. Otherwise, please follow the below instructions to update from the command line:
devel-su ssu re 5.2.0.22
devel-su zypper clean -a
devel-su zypper ref -f
version --dup
reboot
I will build a new set of flashable images for 5.2 later today (including all the improvements to the port since day 1) and make them available on Github & the Verdanditeam website.
5.2 is a fantastic improvement over 5.1. IMO the best advantages are the better browser and full camera support, but new fixes are still coming all the time. Stay tuned, and please let me know if you have any dramas.
