Today's hotpatch (08fd291) has the following changes:
- It's now possible to send links to objects you don't have access to, making it possible for teachers to easily send a link to a student asking them for permissions.
- The recipient in the To column in the outbox was not shown. The sender's name was shown instead. This has now been fixed.
- It was previously possible to iterate through containers forever by specifying an ever-increasing
list_start value to the read_container request handler. This should now emit an error.
