  - Mastodon-compatible `avatar_description` and `header_description` parameters are added to account API responses and as input for `PATCH /api/v1/accounts/update_credentials`
  - `pleroma.background_image_descripption` is added to account API responses
  - `pleroma_background_image_descripption` is added as a new parameter to `PATCH /api/v1/accounts/update_credentials`
+- `GET /api/v1/statuses/:id` contains the new `poll.akkoma.anonymous` parameter if `poll` is non-null.  
+    It relays if and whether the source instance promised to keep votes anonymous or disclose votes with voter identity.
+    There are no plans to enable creating non-anonymous polls in Akkoma, but some implementations do.

 ### Fixed
 - fix date-time format in `* /api/v1/markers` to strictly conform to Mastodon’s ISO 8061 subset

+- `anonymous`: relays whether the poll creator promised to process votes anonymously *(`true`)*,

+    Note this assumes any remote’s claim about its process are true and
+    even if this is truthfully set to `true`, while no regular users ought to have access to voter identities,
+    the server operator of the poll’s home instance may in principle still be able to

 The `GET /api/v1/statuses/:id/source` endpoint additionally has the following attributes:

 - `content_type`: The content type of the status source.
