The second one, flagged as "version 2". But this is a good question, and something I forgot to take care of. I'll work to make the TA selection clear. Thanks for bringing it up!
The app at this location (https://splunkbase.splunk.com/app/1564/) has been updated to mirror the main "Fire Brigade" app selection. If you're already running version 2.0.1 (the prior release) of the TA-fire_brigade, no upgrade is required; the functionality is the same.
