 ## [unreleased]
 
 ### Changed
+- **Breaking:** Elixir >=1.9 is now required (was >= 1.8)
+- In Conversations, return only direct messages as `last_status`
+- Using the `only_media` filter on timelines will now exclude reblog media
+- MFR policy to set global expiration for all local Create activities
+- OGP rich media parser merged with TwitterCard
+- Configuration: `:instance, rewrite_policy` moved to `:mrf, policies`, `:instance, :mrf_transparency` moved to `:mrf, :transparency`, `:instance, :mrf_transparency_exclusions` moved to `:mrf, :transparency_exclusions`. Old config namespace is deprecated.
+
 <details>
   <summary>API Changes</summary>
+
 - **Breaking:** Emoji API: changed methods and renamed routes.
+- Streaming: Repeats of a user's posts will no longer be pushed to the user's stream.
+</details>
+
+<details>
+  <summary>Admin API Changes</summary>
+
+- Status visibility stats: now can return stats per instance.
+
+- Mix task to refresh counter cache (`mix pleroma.refresh_counter_cache`)
 </details>
 
 ### Removed
 - **Breaking:** removed `with_move` parameter from notifications timeline.
 
 ### Added
+
+- Chats: Added support for federated chats. For details, see the docs.
+- ActivityPub: Added support for existing AP ids for instances migrated from Mastodon.
 - Instance: Add `background_image` to configuration and `/api/v1/instance`
 - Instance: Extend `/api/v1/instance` with Pleroma-specific information.
 - NodeInfo: `pleroma:api/v1/notifications:include_types_filter` to the `features` list.
 - NodeInfo: `pleroma_emoji_reactions` to the `features` list.
 - Configuration: `:restrict_unauthenticated` setting, restrict access for unauthenticated users to timelines (public and federate), user profiles and statuses.
 - Configuration: Add `:database_config_whitelist` setting to whitelist settings which can be configured from AdminFE.
+- Configuration: `filename_display_max_length` option to set filename truncate limit, if filename display enabled (0 = no limit).
 - New HTTP adapter [gun](https://github.com/ninenines/gun). Gun adapter requires minimum OTP version of 22.2 otherwise Pleroma won’t start. For hackney OTP update is not required.
 - Mix task to create trusted OAuth App.

 ### Docker
 While we don’t provide docker files, other people have written very good ones. Take a look at <https://github.com/angristan/docker-pleroma> or <https://glitch.sh/sn0w/pleroma-docker>.
 
+### Compilation Troubleshooting
+If you ever encounter compilation issues during the updating of Pleroma, you can try these commands and see if they fix things:
+
+- `mix deps.clean --all`
+- `mix local.rebar`
+- `mix local.hex`
+- `rm -r _build`
+
+If you are not developing Pleroma, it is better to use the OTP release, which comes with everything precompiled.

+# Chats
+
+Chats are a way to represent an IM-style conversation between two actors. They are not the same as direct messages and they are not `Status`es, even though they have a lot in common.
+
+## Why Chats?
+
+There are no 'visibility levels' in ActivityPub, their definition is purely a Mastodon convention. Direct Messaging between users on the fediverse has mostly been modeled by using ActivityPub addressing following Mastodon conventions on normal `Note` objects. In this case, a 'direct message' would be a message that has no followers addressed and also does not address the special public actor, but just the recipients in the `to` field. It would still be a `Note` and is presented with other `Note`s as a `Status` in the API.
+
+This is an awkward setup for a few reasons:
+
+- As DMs generally still follow the usual `Status` conventions, it is easy to accidentally pull somebody into a DM thread by mentioning them. (e.g. "I hate @badguy so much")
+- It is possible to go from a publicly addressed `Status` to a DM reply, back to public, then to a 'followers only' reply, and so on. This can be become very confusing, as it is unclear which user can see which part of the conversation.
+- The standard `Status` format of implicit addressing also leads to rather ugly results if you try to display the messages as a chat, because all the recipients are always mentioned by name in the message.
+- As direct messages are posted with the same api call (and usually same frontend component) as public messages, accidentally making a public message private or vice versa can happen easily. Client bugs can also lead to this, accidentally making private messages public.
+
+As a measure to improve this situation, the `Conversation` concept and related Pleroma extensions were introduced. While it made it possible to work around a few of the issues, many of the problems remained and it didn't see much adoption because it was too complicated to use correctly. 
+
+## Chats explained
+For this reasons, Chats are a new and different entity, both in the API as well as in ActivityPub. A quick overview:
+
+- Chats are meant to represent an instant message conversation between two actors. For now these are only 1-on-1 conversations, but the other actor can be a group in the future.
+- Chat messages have the ActivityPub type `ChatMessage`. They are not `Note`s. Servers that don't understand them will just drop them.
+- The only addressing allowed in `ChatMessage`s is one single ActivityPub actor in the `to` field.
+- There's always only one Chat between two actors. If you start chatting with someone and later start a 'new' Chat, the old Chat will be continued.
+- `ChatMessage`s are posted with a different api, making it very hard to accidentally send a message to the wrong person.
+- `ChatMessage`s don't show up in the existing timelines.
+- Chats can never go from private to public. They are always private between the two actors.
+
+## Caveats
+
+- Chats are NOT E2E encrypted (yet). Security is still the same as email.
+
+## API
+
+In general, the way to send a `ChatMessage` is to first create a `Chat`, then post a message to that `Chat`. `Group`s will later be supported by making them a sub-type of `Account`.
+
+This is the overview of using the API. The API is also documented via OpenAPI, so you can view it and play with it by pointing SwaggerUI or a similar OpenAPI tool to `https://yourinstance.tld/api/openapi`.
+
+### Creating or getting a chat.
+
+To create or get an existing Chat for a certain recipient (identified by Account ID)
+you can call:
+
+`POST /api/v1/pleroma/chats/by-account-id/:account_id`
+
+The account id is the normal FlakeId of the user
+```
+POST /api/v1/pleroma/chats/by-account-id/someflakeid
+```
+
+If you already have the id of a chat, you can also use
+
+```
+GET /api/v1/pleroma/chats/:id
+```
+
+There will only ever be ONE Chat for you and a given recipient, so this call
+will return the same Chat if you already have one with that user.
+
+Returned data:
+
+```json
+{
+  "account": {
+    "id": "someflakeid",
+    "username": "somenick",
+    ...
+  },
+  "id" : "1",
+  "unread" : 2,
+  "last_message" : {...}, // The last message in that chat
+  "updated_at": "2020-04-21T15:11:46.000Z"
+}
+```
+
+### Marking a chat as read
+
+To mark a number of messages in a chat up to a certain message as read, you can use
+
+`POST /api/v1/pleroma/chats/:id/read`
+
+
+Parameters:
+- last_read_id: Given this id, all chat messages until this one will be marked as read. Required.
+
+
+Returned data:
+
+```json
+{
+  "account": {
+    "id": "someflakeid",
+    "username": "somenick",
+    ...
+  },
+  "id" : "1",
+  "unread" : 0,
+  "updated_at": "2020-04-21T15:11:46.000Z"
+}
+```
+
+### Marking a single chat message as read
+
+To set the `unread` property of a message to `false`
+
+`POST /api/v1/pleroma/chats/:id/messages/:message_id/read`
+
+Returned data:
+
+The modified chat message
+
+### Getting a list of Chats
+
+`GET /api/v1/pleroma/chats`
+
+This will return a list of chats that you have been involved in, sorted by their

+   }
+]
+```
+
+The recipient of messages that are sent to this chat is given by their AP ID.
+No pagination is implemented for now.
+
+### Getting the messages for a Chat
+
+For a given Chat id, you can get the associated messages with
+
+`GET /api/v1/pleroma/chats/:id/messages`
+
+This will return all messages, sorted by most recent to least recent. The usual
+pagination options are implemented.
+
+Returned data:
+
+```json
+[
+  {
+    "account_id": "someflakeid",
+    "chat_id": "1",
+    "content": "Check this out :firefox:",
+    "created_at": "2020-04-21T15:11:46.000Z",
+    "emojis": [
+      {
+        "shortcode": "firefox",
+        "static_url": "https://dontbulling.me/emoji/Firefox.gif",
+        "url": "https://dontbulling.me/emoji/Firefox.gif",
+        "visible_in_picker": false
+      }
+    ],

+    "emojis": [],
+    "id": "12",
+    "unread": false
+  }
+]
+```
+
+### Posting a chat message
+
+Posting a chat message for given Chat id works like this:
+
+`POST /api/v1/pleroma/chats/:id/messages`
+
+Parameters:
+- content: The text content of the message. Optional if media is attached.
+- media_id: The id of an upload that will be attached to the message.
+
+Currently, no formatting beyond basic escaping and emoji is implemented.
+
+Returned data:
+
+```json
+{
+  "account_id": "someflakeid",
+  "chat_id": "1",
+  "content": "Check this out :firefox:",
+  "created_at": "2020-04-21T15:11:46.000Z",

+      "visible_in_picker": false
+    }
+  ],
+  "id": "13",
+  "unread": false
+}
+```
+
+### Deleting a chat message
+
+Deleting a chat message for given Chat id works like this:
+
+`DELETE /api/v1/pleroma/chats/:chat_id/messages/:message_id`
+
+Returned data is the deleted message.
+
+### Notifications
+
+There's a new `pleroma:chat_mention` notification, which has this form. It is not given out in the notifications endpoint by default, you need to explicitly request it with `include_types[]=pleroma:chat_mention`:
+
+```json
+{
+  "id": "someid",
+  "type": "pleroma:chat_mention",
+  "account": { ... } // User account of the sender,
+  "chat_message": {
+    "chat_id": "1",
+    "id": "10",
+    "content": "Hello",
+    "account_id": "someflakeid",
+    "unread": false
+  },
+  "created_at": "somedate"
+}
+```
+
+### Streaming
+
+There is an additional `user:pleroma_chat` stream. Incoming chat messages will make the current chat be sent to this `user` stream. The `event` of an incoming chat message is `pleroma:chat_update`. The payload is the updated chat with the incoming chat message in the `last_message` field.
+
+### Web Push
+
+If you want to receive push messages for this type, you'll need to add the `pleroma:chat_mention` type to your alerts in the push subscription.

+# ChatMessages
+
+ChatMessages are the messages sent in 1-on-1 chats. They are similar to
+`Note`s, but the addresing is done by having a single AP actor in the `to`
+field. Addressing multiple actors is not allowed. These messages are always
+private, there is no public version of them. They are created with a `Create`
+activity.
+
+Example:
+
+```json
+{
+  "actor": "http://2hu.gensokyo/users/raymoo",
+  "id": "http://2hu.gensokyo/objects/1",
+  "object": {
+    "attributedTo": "http://2hu.gensokyo/users/raymoo",
+    "content": "You expected a cute girl? Too bad.",
+    "id": "http://2hu.gensokyo/objects/2",
+    "published": "2020-02-12T14:08:20Z",
+    "to": [
+      "http://2hu.gensokyo/users/marisa"
+    ],
+    "type": "ChatMessage"
+  },
+  "published": "2018-02-12T14:08:20Z",
+  "to": [
+    "http://2hu.gensokyo/users/marisa"
+  ],
+  "type": "Create"
+}
+```
+
+This setup does not prevent multi-user chats, but these will have to go through
+a `Group`, which will be the recipient of the messages and then `Announce` them
+to the users in the `Group`.

+# Optimizing your PostgreSQL performance
+
+Pleroma performance depends to a large extent on good database performance. The default PostgreSQL settings are mostly fine, but often you can get better performance by changing a few settings.
+
+You can use [PGTune](https://pgtune.leopard.in.ua) to get recommendations for your setup. If you do, set the "Number of Connections" field to 20, as Pleroma will only use 10 concurrent connections anyway. If you don't, it will give you advice that might even hurt your performance.
+
+We also recommend not using the "Network Storage" option.
+
+## Example configurations

+Here are some configuration suggestions for PostgreSQL 10+.

+# Introduction to Pleroma
+## What is Pleroma?
+Pleroma is a federated social networking platform, compatible with Mastodon and other ActivityPub implementations. It is free software licensed under the AGPLv3.
+It actually consists of two components: a backend, named simply Pleroma, and a user-facing frontend, named Pleroma-FE. It also includes the Mastodon frontend, if that's your thing.
+It's part of what we call the fediverse, a federated network of instances which speak common protocols and can communicate with each other.
+One account on an instance is enough to talk to the entire fediverse!
+
+## How can I use it?
+
+Pleroma instances are already widely deployed, a list can be found at <https://the-federation.info/pleroma> and <https://fediverse.network/pleroma>.
+
+If you don't feel like joining an existing instance, but instead prefer to deploy your own instance, that's easy too!
+Installation instructions can be found in the installation section of these docs.
+
+## I got an account, now what?
+Great! Now you can explore the fediverse! Open the login page for your Pleroma instance (e.g. <https://pleroma.soykaf.com>) and login with your username and password. (If you don't have an account yet, click on Register)
+
+### Pleroma-FE
+The default front-end used by Pleroma is Pleroma-FE. You can find more information on what it is and how to use it in the [Introduction to Pleroma-FE](../frontend).
+
+### Mastodon interface
+If the Pleroma interface isn't your thing, or you're just trying something new but you want to keep using the familiar Mastodon interface, we got that too!
+Just add a "/web" after your instance url (e.g. <https://pleroma.soycaf.com/web>) and you'll end on the Mastodon web interface, but with a Pleroma backend! MAGIC!
+The Mastodon interface is from the Glitch-soc fork. For more information on the Mastodon interface you can check the [Mastodon](https://docs.joinmastodon.org/) and [Glitch-soc](https://glitch-soc.github.io/docs/) documentation.
+
+Remember, what you see is only the frontend part of Mastodon, the backend is still Pleroma.

-# Introduction to Pleroma
-## What is Pleroma?
-Pleroma is a federated social networking platform, compatible with GNU social, Mastodon and other OStatus and ActivityPub implementations. It is free software licensed under the AGPLv3.
-It actually consists of two components: a backend, named simply Pleroma, and a user-facing frontend, named Pleroma-FE. It also includes the Mastodon frontend, if that's your thing.
-It's part of what we call the fediverse, a federated network of instances which speak common protocols and can communicate with each other.
-One account on an instance is enough to talk to the entire fediverse!
-
-## How can I use it?
-
-Pleroma instances are already widely deployed, a list can be found at <http://distsn.org/pleroma-instances.html>. Information on all existing fediverse instances can be found at <https://fediverse.network/>.
-
-If you don't feel like joining an existing instance, but instead prefer to deploy your own instance, that's easy too!
-Installation instructions can be found in the installation section of these docs.
-
-## I got an account, now what?
-Great! Now you can explore the fediverse! Open the login page for your Pleroma instance (e.g. <https://pleroma.soykaf.com>) and login with your username and password. (If you don't have an account yet, click on Register)
-
-At this point you will have two columns in front of you.
-
-### Left column
-
-- first block: here you can see your avatar, your nickname and statistics (Statuses, Following, Followers). Clicking your profile pic will open your profile.
-Under that you have a text form which allows you to post new statuses. The number on the bottom of the text form is a character counter, every instance can have a different character limit (the default is 5000).
-If you want to mention someone, type @ + name of the person. A drop-down menu will help you in finding the right person.
-Under the text form there are also several visibility options and there is the option to use rich text.
-Under that the icon on the left is for uploading media files and attach them to your post. There is also an emoji-picker and an option to post a poll.
-To post your status, simply press Submit.
-On the top right you will also see a wrench icon. This opens your personal settings.
-
-- second block: Here you can switch between the different timelines:
-   - Timeline: all the people that you follow
-   - Interactions: here you can switch between different timelines where there was interaction with your account. There is Mentions, Repeats and Favorites, and New follows
-   - Direct Messages: these are the Direct Messages sent to you
-   - Public Timeline: all the statutes from the local instance
-   - The Whole Known Network: all public posts the instance knows about, both local and remote!
-   - About: This isn't a Timeline but shows relevant info about the instance. You can find a list of the moderators and admins, Terms of Service, MRF policies and enabled features.
-- Optional third block: This is the Instance panel that can be activated, but is deactivated by default. It's fully customisable and by default has links to the pleroma-fe and Mastodon-fe.
-- fourth block: This is the Notifications block, here you will get notified whenever somebody mentions you, follows you, repeats or favorites one of your statuses.
-
-### Right column
-This is where the interesting stuff happens!
-Depending on the timeline you will see different statuses, but each status has a standard structure:
-
-- Profile pic, name and link to profile. An optional left-arrow if it's a reply to another status (hovering will reveal the reply-to status). Clicking on the profile pic will uncollapse the user's profile.
-- A `+` button on the right allows you to Expand/Collapse an entire discussion thread. It also updates in realtime!
-- An arrow icon allows you to open the status on the instance where it's originating from.
-- The text of the status, including mentions and attachements. If you click on a mention, it will automatically open the profile page of that person.
-- Three buttons (left to right): Reply, Repeat, Favorite. There is also a forth button, this is a dropdown menu for simple moderation like muting the conversation or, if you have moderation rights, delete the status from the server.
-
-### Top right
-
-- The magnifier icon opens the search screen where you can search for statuses, people and hashtags. It's also possible to import statusses from remote servers by pasting the url to the post in the search field.
-- The gear icon gives you general settings
-- If you have admin rights, you'll see an icon that opens the admin interface
-- The last icon is to log out
-
-### Bottom right
-On the bottom right you have a chatbox. Here you can communicate with people on the same instance in realtime. It is local-only, for now, but there are plans to make it extendable to the entire fediverse!
-
-### Mastodon interface
-If the Pleroma interface isn't your thing, or you're just trying something new but you want to keep using the familiar Mastodon interface, we got that too!
-Just add a "/web" after your instance url (e.g. <https://pleroma.soycaf.com/web>) and you'll end on the Mastodon web interface, but with a Pleroma backend! MAGIC!
-The Mastodon interface is from the Glitch-soc fork. For more information on the Mastodon interface you can check the [Mastodon](https://docs.joinmastodon.org/) and [Glitch-soc](https://glitch-soc.github.io/docs/) documentation.
