I am not sure if I am the only one or not, but my updates seem to be inline with Google's roll out, not T-Mobile's. For instance, I received the update to MMB29S on the 6th and it included January 2016's Security Patch. I am not sure if anybody else has received the update or if this is just a bug in the system. I am not complaining, I like getting these updates swiftly!
There's monthly security patches.
T-Mobile may not be updating the Software Versions DOC, but you can always look to see valid Nexus image versions at Factory Images for Nexus Devices | Nexus Files for Developers | Google Developers
That is what I have been checking. Thanks for the info, I really did not think about T-Mobile not updating their Version Docs.
