The ones currently in my mirage-dev branch are:

https://github.com/mirage/mirage-dev/compare/master...talex5:better-errors?expand=1

- functoria (allow wrapping for with_mirage_logging and remove old
built-in error handling)
- mirage-{block,net}-{unix,xen} (add pp_error)
- mirage (generate new error handling code)
- mirage-types (change error types, add pp_error)
- tcpip (add pp_error, use logs, new connect sigs)

(and also:
- charrua (just fixes unit-test failure)
- mirage-skeleton (updated configs and network setup)
)
