Added
- The `all of the above` and `check others` modifiers for checkbox
fields.
- The `celery modules` Configuration directive.
- Recipe for calling background tasks from Flask endpoints.
Changed
- When setting up two factor authentication with the authenticator
app, a code is shown in addition to a QR code.
- The way that `objects from file` works has changed; it is no longer
treated as a `mandatory` block, but instead acts like an `objects`
block that is called upon when a variable is needed.
