According to the Blue Series firmware changelog, version 2.15 is the latest release firmware, with 2.17 the latest beta. I have seven Blue switches installed. Four of them are on 2.15, one got updated to 2.17 before I noticed that Z2M was offering beta firmware. One is on 2.14 (an older beta version), and one newly installed switch is on 2.00. Z2M is offering a firmware upgrade for all of them, even the one on 2.17!
I don’t want to pull the trigger on the upgrades from 2.14 and 2.00 because I’d rather stick to production firmware. I have looked through the docs and settings for Z2M and can’t find a way to make it stick to production firmware.
Is there a way to keep Z2M from offering beta firmware?
