 - Rich Media: The crawled URL is now spliced into the rich media data.
 - ActivityPub S2S: sharedInbox usage has been mostly aligned with the rules in the AP specification.
 - ActivityPub S2S: remote user deletions now work the same as local user deletions.
+- ActivityPub S2S: POST requests are now signed with `(request-target)` pseudo-header.
 - Not being able to access the Mastodon FE login page on private instances
 - Invalid SemVer version generation, when the current branch does not have commits ahead of tag/checked out on a tag
 - Pleroma.Upload base_url was not automatically whitelisted by MediaProxy. Now your custom CDN or file hosting will be accessed directly as expected.
 - Report email not being sent to admins when the reporter is a remote user
 - MRF: ensure that subdomain_match calls are case-insensitive
 - Reverse Proxy limiting `max_body_length` was incorrectly defined and only checked `Content-Length` headers which may not be sufficient in some circumstances
+- MRF: fix use of unserializable keyword lists in describe() implementations
 
 ### Added
+- Conversations: Add Pleroma-specific conversation endpoints and status posting extensions. Run the `bump_all_conversations` task again to create the necessary data.
 - **Breaking:** MRF describe API, which adds support for exposing configuration information about MRF policies to NodeInfo.
   Custom modules will need to be updated by adding, at the very least, `def describe, do: {:ok, %{}}` to the MRF policy modules.
 - MRF: Support for priming the mediaproxy cache (`Pleroma.Web.ActivityPub.MRF.MediaProxyWarmingPolicy`)

+# Pleroma Conversations
+
+Pleroma Conversations have the same general structure that Mastodon Conversations have. The behavior differs in the following ways when using these endpoints:
+
+1. Pleroma Conversations never add or remove recipients, unless explicitly changed by the user. 
+2. Pleroma Conversations statuses can be requested by Conversation id.
+3. Pleroma Conversations can be replied to.
+
+Conversations have the additional field "recipients" under the "pleroma" key. This holds a list of all the accounts that will receive a message in this conversation.
+
+The status posting endpoint takes an additional parameter, `in_reply_to_conversation_id`, which, when set, will set the visiblity to direct and address only the people who are the recipients of that Conversation.
+
+
+## `GET /api/v1/pleroma/conversations/:id/statuses`
+### Timeline for a given conversation
+* Method `GET`
+* Authentication: required
+* Params: Like other timelines
+* Response: JSON, statuses (200 - healthy, 503 unhealthy).
+
+## `GET /api/v1/pleroma/conversations/:id`
+### The conversation with the given ID.
+* Method `GET`
+* Authentication: required
+* Params: None
+* Response: JSON, statuses (200 - healthy, 503 unhealthy).
+
+## `PATCH /api/v1/pleroma/conversations/:id`
+### Update a conversation. Used to change the set of recipients.
+* Method `PATCH`
+* Authentication: required
+* Params:
+    * `recipients`: A list of ids of users that should receive posts to this conversation. This will replace the current list of recipients, so submit the full list. The owner of owner of the conversation will always be part of the set of recipients, though.
