1. EPICS
u3hv-scpi guts torn out and started rebuild toward new SCPI command structure. Added an API layer between SCPI command handling and U3A library device interfaces. Debugging U3A readdefaults command problem where the "current" U3 state is not returned correctly. There was at least a problem in the readdefault opcode construction, so this is not a well-tested area. Fixed some U3A memory leaks. libusb seems to be a bit leaky itself. Did I ever tell you I hate USB?
2. Brini Tracker II
Buttons work after a week of runtime. GPS display update still stops responding after a few minutes.
3. Dodecahedron
Generating a polyhedron net using plotrb. Fixed plotrb GCC warning with ruby 2.7.2p137. Nice to see this library getting some use again.
4. ca-r
Added tier data. Have to scrape web page to get CSV data. Disappointing that the distributed CSV file isn't directly parsable because of the way the CSV header is constructed.
5. GEOS
No progress.
6. Books
A couple of books received at Christmas:

6.2. League of Regrettable Superheros
What some people will do to get a kid's dime. Hilarious! https://gone-and-forgotten.blogspot.com/2014/10/the-league-of-regrettable-superheroes.html
