	</details>

	## [1.1.6] - 2019-11-19
	### Fixed
	- Not being able to log into to third party apps when the browser is logged into mastofe
	- Email confirmation not being required even when enabled
	- Mastodon API: conversations API crashing when one status is malformed

	### Bundled Pleroma-FE Changes
	#### Added
	- About page
	- Meme arrows

	#### Fixed
	- Image modal not closing unless clicked outside of image
	- Attachment upload spinner not being centered
	- Showing follow counters being 0 when they are actually hidden

	## [1.1.5] - 2019-11-09
	### Fixed
	- Polls having different numbers in timelines/notifications/poll api endpoints due to cache desyncronization
	- Pleroma API: OAuth token endpoint not being found when ".json" suffix is appended

	### Changed
	- Frontend bundle updated to [044c9ad0](https://git.pleroma.social/pleroma/pleroma-fe/commit/044c9ad0562af059dd961d50961a3880fca9c642)

	## [1.1.4] - 2019-11-01
	### Fixed
	- Added a migration that fills up empty user.info fields to prevent breakage after previous unsafe migrations.
	- Failure to migrate from pre-1.0.0 versions
	- Mastodon API: Notification stream not including follow notifications

	## [1.1.3] - 2019-10-25
	### Fixed
	- Blocked users showing up in notifications collapsed as if they were muted
	- `pleroma_ctl` not working on Debian's default shell

	## [1.1.2] - 2019-10-18
	### Fixed
	- `pleroma_ctl` trying to connect to a running instance when generating the config, which of course doesn't exist.

	## [1.1.1] - 2019-10-18
	### Fixed
	- One of the migrations between 1.0.0 and 1.1.0 wiping user info of the relay user because of unexpected behavior of postgresql's `jsonb_set`, resulting in inability to post in the default configuration. If you were affected, please run the following query in postgres console, the relay user will be recreated automatically:
	```
	delete from users where ap_id = 'https://your.instance.hostname/relay';
	```
	- Bad user search matches

	## [1.1.0] - 2019-10-14
	Breaking: The stable branch has been changed from `master` to `stable`. If you want to keep using 1.0, the `release/1.0` branch will receive security updates for 6 months after 1.1 release.

	OTP Note: `pleroma_ctl` in 1.0 defaults to `master` and doesn't support specifying arbitrary branches, making `./pleroma_ctl update` fail. To fix this, fetch a version of `pleroma_ctl` from 1.1 using the command below and proceed with the update normally:
	```
	curl -Lo ./bin/pleroma_ctl 'https://git.pleroma.social/pleroma/pleroma/raw/develop/rel/files/bin/pleroma_ctl'
	```

	# Differences in Mastodon API responses from vanilla Mastodon

	A Pleroma instance can be identified by "<Mastodon version> (compatible; Pleroma <version>)" present in `version` field in response from `/api/v1/instance`

	## Flake IDs

	Pleroma uses 128-bit ids as opposed to Mastodon's 64 bits. However just like Mastodon's ids they are sortable strings

	## Attachment cap

	Some apps operate under the assumption that no more than 4 attachments can be returned or uploaded. Pleroma however does not enforce any limits on attachment count neither when returning the status object nor when posting.

	## Timelines

	Adding the parameter `with_muted=true` to the timeline queries will also return activities by muted (not by blocked!) users.
	Adding the parameter `exclude_visibilities` to the timeline queries will exclude the statuses with the given visibilities. The parameter accepts an array of visibility types (`public`, `unlisted`, `private`, `direct`), e.g., `exclude_visibilities[]=direct&exclude_visibilities[]=private`.

	## Statuses

	- `visibility`: has an additional possible value `list`

	Has these additional fields under the `pleroma` object:

	- `local`: true if the post was made on the local instance
	- `conversation_id`: the ID of the AP context the status is associated with (if any)
	- `direct_conversation_id`: the ID of the Mastodon direct message conversation the status is associated with (if any)
	- `in_reply_to_account_acct`: the `acct` property of User entity for replied user (if any)
	- `content`: a map consisting of alternate representations of the `content` property with the key being it's mimetype. Currently the only alternate representation supported is `text/plain`
	- `spoiler_text`: a map consisting of alternate representations of the `spoiler_text` property with the key being it's mimetype. Currently the only alternate representation supported is `text/plain`
	- `expires_at`: a datetime (iso8601) that states when the post will expire (be deleted automatically), or empty if the post won't expire
	- `thread_muted`: true if the thread the post belongs to is muted

	## Attachments

	Has these additional fields under the `pleroma` object:

	- `mime_type`: mime type of the attachment.

	## Accounts

	The `id` parameter can also be the `nickname` of the user. This only works in these endpoints, not the deeper nested ones for following etc.

	- `/api/v1/accounts/:id`
	- `/api/v1/accounts/:id/statuses`

	Has these additional fields under the `pleroma` object:

	- `tags`: Lists an array of tags for the user
	- `relationship{}`: Includes fields as documented for Mastodon API https://docs.joinmastodon.org/api/entities/#relationship
	- `is_moderator`: boolean, nullable, true if user is a moderator
	- `is_admin`: boolean, nullable, true if user is an admin
	- `confirmation_pending`: boolean, true if a new user account is waiting on email confirmation to be activated
	- `hide_followers`: boolean, true when the user has follower hiding enabled
	- `hide_follows`: boolean, true when the user has follow hiding enabled
	- `hide_followers_count`: boolean, true when the user has follower stat hiding enabled
	- `hide_follows_count`: boolean, true when the user has follow stat hiding enabled
	- `settings_store`: A generic map of settings for frontends. Opaque to the backend. Only returned in `verify_credentials` and `update_credentials`
	- `chat_token`: The token needed for Pleroma chat. Only returned in `verify_credentials`
	- `deactivated`: boolean, true when the user is deactivated
	+- `allow_following_move`: boolean, true when the user allows automatically follow moved following accounts
	- `unread_conversation_count`: The count of unread conversations. Only returned to the account owner.

	### Source

	Has these additional fields under the `pleroma` object:

	- `show_role`: boolean, nullable, true when the user wants his role (e.g admin, moderator) to be shown
	- `no_rich_text` - boolean, nullable, true when html tags are stripped from all statuses requested from the API

	## Conversations

	Has an additional field under the `pleroma` object:

	- `recipients`: The list of the recipients of this Conversation. These will be addressed when replying to this conversation.

	## GET `/api/v1/conversations`

	Accepts additional parameters:

	- `recipients`: Only return conversations with the given recipients (a list of user ids). Usage example: `GET /api/v1/conversations?recipients[]=1&recipients[]=2`

	## Account Search

	Behavior has changed:

	- `/api/v1/accounts/search`: Does not require authentication


	## Notifications

	Has these additional fields under the `pleroma` object:

	- `is_seen`: true if the notification was read by the user

	+### Move Notification
	+
	+The `type` value is `move`. Has an additional field:
	+
	+- `target`: new account
	+
	## GET `/api/v1/notifications`

	Accepts additional parameters:

	- `exclude_visibilities`: will exclude the notifications for activities with the given visibilities. The parameter accepts an array of visibility types (`public`, `unlisted`, `private`, `direct`). Usage example: `GET /api/v1/notifications?exclude_visibilities[]=direct&exclude_visibilities[]=private`.

	## POST `/api/v1/statuses`

	Additional parameters can be added to the JSON body/Form data:

	- `preview`: boolean, if set to `true` the post won't be actually posted, but the status entitiy would still be rendered back. This could be useful for previewing rich text/custom emoji, for example.
	- `content_type`: string, contain the MIME type of the status, it is transformed into HTML by the backend. You can get the list of the supported MIME types with the nodeinfo endpoint.
	- `to`: A list of nicknames (like `lain@soykaf.club` or `lain` on the local server) that will be used to determine who is going to be addressed by this post. Using this will disable the implicit addressing by mentioned names in the `status` body, only the people in the `to` list will be addressed. The normal rules for for post visibility are not affected by this and will still apply.
	- `visibility`: string, besides standard MastoAPI values (`direct`, `private`, `unlisted` or `public`) it can be used to address a List by setting it to `list:LIST_ID`.
	- `expires_in`: The number of seconds the posted activity should expire in. When a posted activity expires it will be deleted from the server, and a delete request for it will be federated. This needs to be longer than an hour.
	- `in_reply_to_conversation_id`: Will reply to a given conversation, addressing only the people who are part of the recipient set of that conversation. Sets the visibility to `direct`.

	## GET `/api/v1/statuses`

	An endpoint to get multiple statuses by IDs.

	Required parameters:

	- `ids`: array of activity ids

	Usage example: `GET /api/v1/statuses/?ids[]=1&ids[]=2`.

	Returns: array of Status.

	The maximum number of statuses is limited to 100 per request.

	## PATCH `/api/v1/update_credentials`

	Additional parameters can be added to the JSON body/Form data:

	- `no_rich_text` - if true, html tags are stripped from all statuses requested from the API
	- `hide_followers` - if true, user's followers will be hidden
	- `hide_follows` - if true, user's follows will be hidden
	- `hide_followers_count` - if true, user's follower count will be hidden
	- `hide_follows_count` - if true, user's follow count will be hidden
	- `hide_favorites` - if true, user's favorites timeline will be hidden
	- `show_role` - if true, user's role (e.g admin, moderator) will be exposed to anyone in the API
	- `default_scope` - the scope returned under `privacy` key in Source subentity
	- `pleroma_settings_store` - Opaque user settings to be saved on the backend.
	- `skip_thread_containment` - if true, skip filtering out broken threads
	+- `allow_following_move` - if true, allows automatically follow moved following accounts
	- `pleroma_background_image` - sets the background image of the user.

	### Pleroma Settings Store
	Pleroma has mechanism that allows frontends to save blobs of json for each user on the backend. This can be used to save frontend-specific settings for a user that the backend does not need to know about.

	The parameter should have a form of `{frontend_name: {...}}`, with `frontend_name` identifying your type of client, e.g. `pleroma_fe`. It will overwrite everything under this property, but will not overwrite other frontend's settings.

	This information is returned in the `verify_credentials` endpoint.

	## Authentication

	*Pleroma supports refreshing tokens.

	`POST /oauth/token`
	Post here request with grant_type=refresh_token to obtain new access token. Returns an access token.

	## Account Registration
	`POST /api/v1/accounts`

	Has theses additionnal parameters (which are the same as in Pleroma-API):
	* `fullname`: optional
	* `bio`: optional
	* `captcha_solution`: optional, contains provider-specific captcha solution,
	* `captcha_token`: optional, contains provider-specific captcha token
	* `token`: invite token required when the registerations aren't public.
