 ## [Unreleased]
+### Security
+- OStatus: eliminate the possibility of a protocol downgrade attack.
+- OStatus: prevent following locked accounts, bypassing the approval process.
+
 ### Changed
 - **Breaking:** Configuration: A setting to explicitly disable the mailer was added, defaulting to true, if you are using a mailer add `config :pleroma, Pleroma.Emails.Mailer, enabled: true` to your config
 - **Breaking:** Configuration: `/media/` is now removed when `base_url` is configured, append `/media/` to your `base_url` config to keep the old behaviour if desired

 ### Fixed
 - Not being able to pin unlisted posts
+- Objects being re-embedded to activities after being updated (e.g faved/reposted). Running 'mix pleroma.database prune_objects' again is advised.
 - Metadata rendering errors resulting in the entire page being inaccessible
 - Federation/MediaProxy not working with instances that have wrong certificate order

 - ActivityPub S2S: sharedInbox usage has been mostly aligned with the rules in the AP specification.

 - 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

 # How to activate mediaproxy
 ## Explanation
 
-Without the `mediaproxy` function, Pleroma don't store any remote content like pictures, video etc. locally. So every time you open Pleroma, the content is loaded from the source server, from where the post is coming. This can result in slowly loading content or/and increased bandwidth usage on the source server.
