New release 2.2.0 is available.
I see here on my system also some hashrate improvements for ProgPoW and MTP, but it may be my 'overoptimized' system.
So I do not know if you will see this improvements as well. I see them at default settings ( default intensity and default grid size).
Please let me know if you run into any issues.
Happy mining.
