Legacy Tablo app for Roku

On a forum I am on for Roku devices, they mention a Tablo TV update to 3.1.0. Not sure if there was a real update. It didn’t do anything with audio on a remote TV connecting to an HDMI Legacy. Was there an actual update, or did they get the Legacy and Gen4 updates mixed up?

The only update we’ve released today has been Roku v. 0.8.900 for 4th Generation.
