chore(release): 3.0.0 [skip ci]

# [3.0.0](v2.3.2...v3.0.0) (2021-07-28)

### Bug Fixes

* conflation of a user's Sub and their Username ([ece63b6](ece63b6))

### BREAKING CHANGES

* potential -- the autogenerated Sub and user-supplied
Username were treated interchangeably before, but now are independent.
Previously lookups by the Sub attribute were possible, but it now
doesn't appear necessary so has been removed. Databases should be
unaffected.
