## 0.1.0

* What every Halkyon server has, from Halkyon Learn's server: anonymous,
  GitHub and email code sign-in with their endpoints, the account's ways in
  and its deletion (with the host's own deletions, `HalkyonBase.deletePersonData`),
  the pruning of abandoned anonymous people, of sign-up attempts and of
  expired codes, and the instance's basics (`instance.basics()`). The tables
  `email_identity` and `email_code_request` are as Halkyon Learn has them.
