That's the last version that was released before the transfer AFAIK. Someone in the linked thread also said they didn't see anything suspicious between 2.0.11.1 and 2.0.11.2.
Good to know, thank you. I think the only thing I worry about with BT is vulnerabilities. Not sure if ZigBee is any more secure but I've heard of a lot of BT vulns in the past. Probably doesn't matter for a temp sensor, so probably just important for the dongle/driver being used with HA.
Thanks for the tips, was planning on trying this out.
