I have a pair of S2 receivers and notice that most of the firmware upgrades for the past year or two at least, are related to features and fixes for the Duo and S3. My question is: what is the most stable and feature specific firmware version for the FDM-S2? I don't see that I need much of the newer firmware and am sure there are good opinions out there, specific to the S2 radio.

Also, any further news on an upgrade to DRM? A reasonable paid upgrade would be OK!
