 ### Changed
 - Return HTTP error 413 when uploading an avatar or banner that's above the configured upload limit instead of a 500.
 - Non-admin users now cannot register `admin` scope tokens (not security-critical, they didn't work before, but you _could_ create them)
+- Rich media will now backoff for 20 minutes after a failure
 
 ### Upgrade notes
 - Ensure `config :tesla, :adapter` is either unset, or set to `{Tesla.Adapter.Finch, name: MyFinch}` in your .exs config
