[DRBD-user] confused with DRBD 9.0 and dual-primary

i found: 
"With current DRBD-9.0 version running in Dual-Primary mode is not recommended (because of lack of testing).
In DRBD-9.1 it will be possible to have more than two primaries at the same time."

Clear statement. I'm using SLES 12 SP3 with DRBD 9.0.8. Is DRBD 9.1 already available ?
I have a two-node cluster and like to have live migration with virtual machines as resources.
For that i need dual-primary, right ?

I found some tarballs:

The kernel modules are 9.0.x.
The drbd-utils i found are 9.x.

Are these already dual-primary capable ?

Thanks for a clarification.
