But as someone who has done semver for mobile apps, this would suggest to me that they released 5.1.0 to some size of audience, it had issues, they released 5.1.1 to the same audience, it had issues, they released 5.1.2, and it performed well, so they gave it to everyone... or maybe I'm just in the 5% that's getting 5.1.2.

The only thing I noticed immediately (based on the changelog) was the Altitude card and the "use NEXUS for US check-in" option. I can do a proper test of the latter option on Thursday night.
