Successfully updated from 2.1.3.7 to 2.1.4.13 on my XperiaX. Everything seems to work fine (including Patchmanager). Only warehouse which was removed during the update, but that was to be expected.

Edit: Successfully replaced it with storeman, v0.0.16-3 works like a charm.

Haven't found any issues yet, but the system somehow feels more responsive and fluent.
