[April 2021] New DB and OMEMO 0.7.0
Pre-releaseA LOT has changed in the last couple of months in UWPX.
I undertook the adventure of replacing the badly maintained SQLite-net DB backend with a new Entity Framework Core DB.
With this I was finally able to fix and update my OMEMO implementation to the latest version of the draft (OMEMO 0.7.0 (2020-09-05)).
This version is incompatible with all other previous versions of OMEMO and UWPX allows you now to only exchange OMEMO encrypted messages with contacts that support at least OMEMO 0.7.0 (2020-09-05) draft.
This should now finally allow UWPX to act as a client with a propper one to one OMEMO implementation!
Since we have new DB backend, the old DB is incompatible and you have to add your accounts again.
Please report bugs here!
