### New Features
- Implemented `/_telodendria/admin/v1/deactivate/[localpart]` for admins to be able to
deactivate users.
- Moved all administrator API endpoints to `/_telodendria/admin/v1`, because later revisions
of the administrator API may break clients, so we want a way to give those breaking revisions
new endpoints.
- Implemented `/_telodendria/admin/v1/deactivate/[localpart]` for admins to be able to
deactivate users.
- Implemented the following APIs for managing registration tokens:
- **GET** `/_telodendria/admin/tokens`
- **GET** `/_telodendria/admin/tokens/[token]`
- **POST** `/_telodendria/admin/tokens`
- **DELETE** `/_telodendria/admin/tokens/[token]`
## v0.3.0
