Playback Designs MPS-5 firmware update version 029 - anybody updated?

Since we have a few owners on the forum and I have been unable to find anything on the web from owners - has anybody updated their PBD to this new firmware version? I am not sure when it was released, I only noticed it was available today. I updated my machine to 027 back in August '16 and gained a massive improvement in SQ, is this new version better again? I am only asking because I recall a few years ago some owners being unhappy with one of the updates but were unable to revert to the previous version.

Cheers,

Simon
