Was there a change in the way b2 works sometime in the last 12 months, or did I set up the system incorrectly?

Yes, it appears that there was a change, judging by the history of link.jam: https://github.com/boostorg/build/commits/develop/src/tools/link.jam Specifically, it looks like it was this Feb 5 change: https://github.com/boostorg/build/commit/3116da2b95ad02748c744a44ecec67789a9... In summary, you did nothing wrong, you just did your setup before this change. Life in develop is sometimes like that, and having to delete boost/ and rerun b2 headers a few times a year is nothing extraordinary. :-)
