If you are not in rush, you can get this info.

In nearest hours, we going to ship Valentina 3.3 release,
And we will start work on 3.4 build.

For this build we going to add at least basic features of replication, what
includes two aspects In fact:
    a) Vserver to Vserver replication
    b) off-line client to Vserver synch.


What is your task you need to solve?
