# API changelog
This page documents changes to the Zulip Server API over time. See also
the [Zulip server changelog][server-changelog].
The recommended way for a client like the Zulip mobile or desktop apps
that needs to support interaction with a wide range of different Zulip
server versions is to check the `zulip_feature_level` parameter in the
`/register` and `/server_settings` responses to determine which of the
below features are supported.
## Changes in Zulip 5.0
**Feature level 107**
* [`POST /register`](/api/register-queue), [`PATCH /settings`](/api/update-settings),
[`PATCH /realm/user_settings_defaults`](/api/update-realm-user-settings-defaults):
Added user setting `escape_navigates_to_default_view` to allow users to
[disable the keyboard shortcut](/help/configure-default-view) for the `Esc` key that
navigates the app to the default view.
**Feature level 106**
* [`PATCH /user/{user_id}`](/api/update-user): Removed unnecessary JSON-encoding of string
parameter `full_name`.
**Feature level 105**
* [`POST /register`](/api/register-queue), [`PATCH
/settings`](/api/update-settings), [`PATCH
/realm/user_settings_defaults`](/api/update-realm-user-settings-defaults):
Added three new privacy settings: `send_private_typing_notifications`,
`send_stream_typing_notifications`, and `send_read_receipts`.
**Feature level 104**
* [`PATCH /realm`]: Added `string_id` parameter for changing an
organization's subdomain. Currently, this is only allowed for
changing changing a demo organization to a normal one.
**Feature level 103**
* [`POST /register`](/api/register-queue): Added `create_web_public_stream_policy`
policy for which users can create web public streams.
* [`PATCH /realm`]: Added support for updating `create_web_public_stream_policy`.
* [`POST /register`](/api/register-queue): Added `can_create_web_public_streams` boolean
field to the response.
**Feature level 102**
* [`POST /register`](/api/register-queue), `PATCH /realm`: The
`create_stream_policy` setting was split into two settings for
different types of streams: `create_private_stream_policy` and
`create_public_stream_policy`.
* [`POST /register`](/api/register-queue): The `create_stream_policy`
property was deprecated in favor of the
`create_private_stream_policy` and `create_public_stream_policy`
properties, but it still available for backwards-compatibility.
**Feature level 101**
* [`POST /register`](/api/register-queue), `PATCH /realm`: Replaced
the `allow_message_deleting` boolean field with an integer field
`delete_own_message_policy` defining which roles can delete messages
they had sent.
**Feature level 100**
* [`POST /register`](/api/register-queue), [`GET
/events`](/api/get-events): `message_content_delete_limit_seconds`
now represents no limit using `null`, instead of the integer 0.
* `PATCH /realm`: One now sets `message_content_delete_limit_seconds`
to no limit by passing the string `unlimited`, rather than the
integer 0.
**Feature level 99**
* [`PATCH /realm/user_settings_defaults`](/api/update-realm-user-settings-defaults),
`PATCH /realm`: The `default_twenty_four_hour_time` parameter to
`PATCH /realm` has been replaced by the `twenty_four_hour_time` parameter
to `PATCH /realm/user_settings_defaults`, to match the new model for
user preference defaults settings.
* [`POST /register`](/api/register-queue): Removed `realm_default_twenty_four_hour_time`
from the response object. This value is now available in the
`twenty_four_hour_time` field of the `realm_user_settings_default` object.
**Feature level 98**
* [`POST /subscribe`](/api/subscribe): Added `is_web_public` parameter
for requesting the creation of a web-public stream.
* [`PATCH /streams/{stream_id}`](/api/update-stream): Added
`is_web_public` parameter for converting a stream into a web-public stream.
**Feature level 97**
* `GET /realm/emoji`, `POST /realm/emoji/{emoji_name}`, [`GET
/events`](/api/get-events), [`POST /register`](/api/register-queue):
Custom emoji objects may now contain a `still_url` field, with the
URL of a PNG still image version of the emoji. This field will only be
present for animated emoji.
**Feature level 96**
* [`PATCH /realm/user_settings_defaults`](/api/update-realm-user-settings-defaults):
Added new endpoint to update default values of user settings in a realm.
**Feature level 95**
* [`POST /register`](/api/register-queue): Added
`realm_user_settings_defaults` object, containing default values of
personal user settings for new users in the realm.
* [`GET /events`](/api/get-events): Added
`realm_user_settings_defaults` event type, which is sent when the
organization's configured default settings for new users change.
**Feature level 94**
* [`POST /register`](/api/register-queue): Added
`demo_organization_scheduled_deletion_date` field to realm data.
**Feature level 93**
* [`POST /register`](/api/register-queue), [`GET /user_groups`](/api/get-user-groups),
[`GET /events`](/api/get-events): Added `is_system_group` field to user group
objects.
**Feature level 92**
* [`GET /messages`](/api/get-messages), [`POST
/register`](/api/register-queue), [`GET /users`](/api/get-users),
[`GET /users/{user_id}`](/api/get-user), [`GET
/users/{email}`](/api/get-user-by-email): The `client_gravatar`
parameter now defaults to `true`.
**Feature level 91**
* `PATCH /realm`, [`PATCH /streams/{stream_id}`](/api/update-stream):
These endpoints now accept `"unlimited"` for `message_retention_days`,
replacing `"forever"` as the way to encode a retention policy where
messages are not automatically deleted.
**Feature level 90**
* [`POST /register`](/api/register-queue): The `unread_msgs` section
of the response no longer includes `sender_ids` in the `streams`
dictionaries. These were removed because no clients were interested
in using the data, which required substantial complexity to
construct correctly.
**Feature level 89**
* [`GET /events`](/api/get-events): Introduced the `user_settings`
event type, unifying and replacing the previous
`update_display_settings` and `update_global_notifications` event
types. The legacy event types are still supported for backwards
compatibility, but will be removed in a future release.
* [`POST /register`](/api/register-queue): Added `user_settings` field
in the response, which is a dictionary containing all the user's
personal settings. For backwards-compatibility, individual settings
will still appear in the top-level response for clients don't
support the `user_settings_object` client capability.
* [`POST /register`](/api/register-queue): Added the
`user_settings_object` property to supported `client_capabilities`.
When enabled, the server will not include a duplicate copy of
personal settings in the top-level response.
* [`GET /events`](/api/get-events): `update_display_settings` and
`update_global_notifications` events now only sent to clients that
did not include `user_settings_object` in their
`client_capabilities` when the event queue was created.
**Feature level 88**
* [`POST /register`](/api/register-queue): Added `zulip_merge_base`
field to the response.
* [`GET /events`](/api/get-events): Added new `zulip_merge_base`
field to the `restart` event.
* [`GET /server_settings`](/api/get-server-settings): Added
`zulip_merge_base` to the responses which can be used to
make "About Zulip" widgets in clients.
**Feature level 87**
* [`PATCH /settings`](/api/update-settings): Added a new
`enable_drafts_synchronization` setting, which controls whether the
syncing drafts between different clients is enabled.
* [`GET /events`](/api/get-events), [`POST /register`](/api/register-queue):
Added new `enable_drafts_synchronization` setting under
`update_display_settings`.
* [`GET /drafts`](/api/get-drafts): Added new endpoint to fetch user's
synced drafts from the server.
* [`POST /drafts`](/api/create-drafts): Added new endpoint to create
drafts when syncing has been enabled.
* [`PATCH /drafts/{draft_id}`](/api/edit-draft): Added new endpoint
to edit a draft already owned by the user.
* [`DELETE /drafts/{draft_id}`](/api/delete-draft): Added new endpoint
to delete a draft already owned by the user.
**Feature level 86**
* [`GET /events`](/api/get-events): Added `emoji_name`,
`emoji_code`, and `reaction_type` fields to `user_status` objects.
* [`POST /register`](/api/register-queue): Added `emoji_name`,
`emoji_code`, and `reaction_type` fields to `user_status` objects.
* `POST /users/me/status`: Added support for new `emoji_name`,
`emoji_code`, and `reaction_type` parameters.
**Feature level 85**
* [`POST /register`](/api/register-queue), `PATCH /realm`: Replaced `add_emoji_by_admins_only`
field with an integer field `add_custom_emoji_policy`.
**Feature level 84**
* [`POST /register`](/api/register-queue): The `enter_sends` setting
is now sent when `update_display_setting` is present in
`fetch_event_types` instead of `realm_user`.
**Feature level 83**
* * [`POST /register`](/api/register-queue): The `cross_realm_bots`
section of the response now uses the `is_system_bot` flag to
indicate whether the bot is a system bot.
**Feature level 82**
* [`PATCH /settings`](/api/update-settings) now accepts a new
`email_notifications_batching_period_seconds` field for setting the
time duration for which the server will collect email notifications
before sending them.
**Feature level 81**
* `POST /users/me/enter-sends` has been removed. The `enter_sends`
setting is now edited using the normal [`PATCH
/settings`](/api/update-settings) endpoint.
**Feature level 80**
* [`PATCH /settings`](/api/update-settings): The
`/settings/notifications` and `/settings/display` endpoints were
merged into the main `/settings` endpoint; now all personal settings
should be edited using that single endpoint. The old URLs are
preserved as deprecated aliases for backwards compatibility.
**Feature level 79**
* [`GET /users/me/subscriptions`](/api/get-subscriptions): The
`subscribers` field now returns user IDs if `include_subscribers` is
passed. Previously, this endpoint returned user display email
addresses in this field.
* `GET /streams/{stream_id}/members`: This endpoint now returns user
IDs. Previously, it returned display email addresses.
**Feature level 78**
* [`PATCH /settings`](/api/update-settings): Added
`ignored_parameters_unsupported` field, which is a list of
parameters that were ignored by the endpoint, to the response
object.
* [`PATCH /settings`](/api/update-settings): Removed `full_name` and
`account_email` fields from the response object.
**Feature level 77**
* [`GET /events`](/api/get-events): Removed `recipient_id` and
`sender_id` field in responses of `delete_message` event when
`message_type` is `private`.
**Feature level 76**
* [`POST /fetch_api_key`](/api/fetch-api-key), [`POST
/dev_fetch_api_key`](/api/dev-fetch-api-key): The HTTP status for
authentication errors is now 401. This was previously 403.
* All API endpoints now use the HTTP 401 error status for API requests
involving a deactivated user or realm. This was previously 403.
* Mobile push notifications now include the `mentioned_user_group_id`
and `mentioned_user_group_name` fields when a user group containing
the user is mentioned. Previously, these were indistinguishable
from personal mentions (as both types have `trigger="mention"`).
**Feature level 75**
* [`POST /register`](/api/register-queue), `PATCH /realm`: Replaced `allow_community_topic_editing`
field with an integer field `edit_topic_policy`.
**Feature level 74**
* [`POST /register`](/api/register-queue): Added `server_needs_upgrade`
and `event_queue_longpoll_timeout_seconds` field when fetching
realm data.
**Feature level 73**
* [`GET /users`](/api/get-users), [`GET /users/{user_id}`](/api/get-user),
[`GET /users/{email}`](/api/get-user-by-email) and
[`GET /users/me`](/api/get-own-user): Added is `user_billing_admin` field to
returned user objects.
* [`GET /events`](/api/get-events): Added `is_billing_admin` field to
user objects sent in `realm_user` events.
* [`POST /register`](/api/register-queue): Added `is_billing_admin` field
in the user objects returned in the `realm_users` field.
**Feature level 72**
* [`POST /register`](/api/register-queue): Renamed `max_icon_file_size` to
`max_icon_file_size_mib`, `realm_upload_quota` to `realm_upload_quota_mib`
and `max_logo_file_size` to `max_logo_file_size_mib`.
**Feature level 71**
* [`GET /events`](/api/get-events): Added `is_web_public` field to
`stream` events changing `invite_only`.
**Feature level 70**
* [`POST /register`](/api/register-queue): Added new top-level
`server_timestamp` field when fetching presence data, to match the
existing presence API.
Feature levels 66-69 are reserved for future use in 4.x maintenance
releases.

refactor: Eliminate checks in build_stream_dict_for_sub. We eliminate some redundant checks. We also consistently provide a `subscribers` field in our stream data with `[]`, even if our users can't access subscribers. We therefore bump the API version and tweak the docs. (See further down for a detailed justification of the change.) Even though it is sometimes fine to have redundant code that is defensive in nature, some upcoming changes are gonna move subscriber-related logic out of build_stream_dict_for_sub for certain codepaths as part of our effort to streamline the payload for subscribers within page_params. So we can't rely on the code that I removed here inside of build_stream_dict_for_sub. Anyway, it makes more sense to do these checks explicitly in the validate function. The code in build_stream_dict_for_sub was almost effectively a noop, since the validation function was already preventing us from getting subscriber info. The only difference it made was sometimes converting `[]` to `None`, and then subsequently omitting the subscribers field. Neither ZT nor the webapp make any distinction between `[]` or <missing key> for the `subscribers` data in `page_params`. The webapp has had this code for a long time (and now equivalent code elsewhere in this PR): if (!Object.prototype.hasOwnProperty.call(sub, "subscribers")) { sub.subscribers = new LazySet([]); } The webapp calculates access based on booleans, anyway: sub.can_access_subscribers = page_params.is_admin || sub.subscribed || (!page_params.is_guest && !sub.invite_only); And ZT would choke if `subscribers` were missing, except that it never gets to the relevant code due to other checks: def get_other_subscribers_in_stream(<snip>): assert stream_id is not None or stream_name is not None if stream_id: assert self.is_user_subscribed_to_stream(stream_id) return [sub for sub in self.stream_dict[stream_id]['subscribers'] if sub != self.user_id] else: return [sub for _, stream in self.stream_dict.items() for sub in stream['subscribers'] if stream['name'] == stream_name if sub != self.user_id] You could make a semantic argument that we should prefer <missing key> to `[]` when subscribers aren't even available, but we have precedent from the way that `bulk_get_subscriber_user_ids` has traditionally populated its result: result: Dict[int, List[int]] = {stream["id"]: [] for stream in stream_dicts} If we changed `stream_dicts` to `target_stream_dicts` we would faciliate a move toward `None`, but it would just cause headaches for other server code as well as the frontends (which, to reiterate, already prefer the empty array for convenience).
2021-01-14 16:18:42 +01:00
**Feature level 37**
* Consistently provide `subscribers` in stream data when
clients register for subscriptions with `include_subscribers`,
even if the user can't access subscribers.
**Feature level 36**
* [`POST /users`](/api/create-user): Restricted access to organization
administrators with the `can_create_users` permission.
2021-07-01 20:38:57 +02:00
* [Error handling](/api/rest-error-handling): The `code` property will
not be present in errors due to rate limits.
**Feature level 35**
* The peer_add and peer_remove subscription events now have plural
versions of `user_ids` and `stream_ids`.
**Feature level 34**
* [`POST /register`](/api/register-queue): Added a new `wildcard_mention_policy`
setting for controlling who can use wildcard mentions in large streams.
**Feature level 33**
* Markdown code blocks now have a `data-code-language` attribute
attached to the outer `div` element, recording the programming
language that was selecting for syntax highlighting. This field
supports the upcoming "view in playground" feature for code blocks.
**Feature level 32**
* [`GET /events`](/api/get-events): Added `op` field to
`update_message_flags` events, deprecating the `operation` field
(which has the same value). This removes an unintentional anomaly
in the format of this event type.
**Feature level 31**
* [`GET users/me/subscriptions`](/api/get-subscriptions): Added a
`role` field to Subscription objects representing whether the user
is a stream administrator.
* [`GET /events`](/api/get-events): Added `role` field to
Subscription objects sent in `subscriptions` events.
Note that as of this feature level, stream administrators are a
partially completed feature. In particular, it is impossible for a
user to be a stream administrator at this feature level.
**Feature level 30**
* [`GET users/me/subscriptions`](/api/get-subscriptions), [`GET
/streams`](/api/get-streams): Added `date_created` to Stream
objects.
* [`POST /users`](/api/create-user), `POST /bots`: The ID of the newly
created user is now returned in the response.
Feature levels 28 and 29 are reserved for future use in 3.x bug fix
releases.
## Changes in Zulip 3.1
**Feature level 27**
* The `short_name` field is removed from `display_recipients`
in `POST /users`.
**Feature level 26**
* The `sender_short_name` field is no longer included in
`GET /messages`.
* The `short_name` field is removed from `display_recipients`
in `GET /messages`.
## Changes in Zulip 3.0
2020-07-16 11:13:43 +02:00
**Feature level 25**
No changes; feature level used for Zulip 3.0 release.
markdown: Remove !avatar() and !gravatar() syntax. This particular commit has been a long time coming. For reference, !avatar(email) was an undocumented syntax that simply rendered an inline 50px avatar for a user in a message, essentially allowing you to create a user pill like: `!avatar(alice@example.com) Alice: hey!` --- Reimplementation If we decide to reimplement this or a similar feature in the future, we could use something like `<avatar:userid>` syntax which is more in line with creating links in markdown. Even then, it would not be a good idea to add this instead of supporting inline images directly. Since any usecases of such a syntax are in automation, we do not need to make it userfriendly and something like the following is a better implementation that doesn't need a custom syntax: `![avatar for Alice](/avatar/1234?s=50) Alice: hey!` --- History We initially added this syntax back in 2012 and it was 'deprecated' from the get go. Here's what the original commit had to say about the new syntax: > We'll use this internally for the commit bot. We might eventually > disable it for external users. We eventually did start using this for our github integrations in 2013 but since then, those integrations have been neglected in favor of our GitHub webhooks which do not use this syntax. When we copied `!gravatar` to add the `!avatar` syntax, we also noted that we want to deprecate the `!gravatar` syntax entirely - in 2013! Since then, we haven't advertised either of these syntaxes anywhere in our docs, and the only two places where this syntax remains is our game bots that could easily do without these, and the git commit integration that we have deprecated anyway. We do not have any evidence of someone asking about this syntax on chat.zulip.org when developing an integration and rightfully so- only the people who work on Zulip (and specifically, markdown) are likely to stumble upon it and try it out. This is also the only peice of code due to which we had to look up emails -> userid mapping in our backend markdown. By removing this, we entirely remove the backend markdown's dependency on user emails to render messages. --- Relevant commits: - Oct 2012, Initial commit c31462c2782a33886e737cf33424a36a95c81f97 - Nov 2013, Update commit bot 968c393826f8846065c5c880427328f6e534c2f5 - Nov 2013, Add avatar syntax 761c0a0266669aca82d134716a4d6b6e33d541fc - Sep 2017, Avoid email use c3032a7fe8ed49b011e0d242f4b8a7d756b9f647 - Apr 2019, Remove from webhook 674fcfcce1fcf35bdc57031a1025ef169d495d36

**Feature level 24**
* The `!avatar()` and `!gravatar()` Markdown syntax, which was never
documented, had inconsistent syntax, and was rarely used, was
removed.
markdown: Remove !avatar() and !gravatar() syntax. This particular commit has been a long time coming. For reference, !avatar(email) was an undocumented syntax that simply rendered an inline 50px avatar for a user in a message, essentially allowing you to create a user pill like: `!avatar(alice@example.com) Alice: hey!` --- Reimplementation If we decide to reimplement this or a similar feature in the future, we could use something like `<avatar:userid>` syntax which is more in line with creating links in markdown. Even then, it would not be a good idea to add this instead of supporting inline images directly. Since any usecases of such a syntax are in automation, we do not need to make it userfriendly and something like the following is a better implementation that doesn't need a custom syntax: `![avatar for Alice](/avatar/1234?s=50) Alice: hey!` --- History We initially added this syntax back in 2012 and it was 'deprecated' from the get go. Here's what the original commit had to say about the new syntax: > We'll use this internally for the commit bot. We might eventually > disable it for external users. We eventually did start using this for our github integrations in 2013 but since then, those integrations have been neglected in favor of our GitHub webhooks which do not use this syntax. When we copied `!gravatar` to add the `!avatar` syntax, we also noted that we want to deprecate the `!gravatar` syntax entirely - in 2013! Since then, we haven't advertised either of these syntaxes anywhere in our docs, and the only two places where this syntax remains is our game bots that could easily do without these, and the git commit integration that we have deprecated anyway. We do not have any evidence of someone asking about this syntax on chat.zulip.org when developing an integration and rightfully so- only the people who work on Zulip (and specifically, markdown) are likely to stumble upon it and try it out. This is also the only peice of code due to which we had to look up emails -> userid mapping in our backend markdown.

2020-07-06 23:01:38 +02:00
**Feature level 23**
* `GET/PUT/POST /users/me/pointer`: Removed. Zulip 3.0 removes the
`pointer` concept from Zulip; this legacy data structure was
replaced by tracking unread messages and loading views centered on
the first unread message.
**Feature level 22**
* [`GET /attachments`](/api/get-attachments): The date when a message
using the attachment was sent is now correctly encoded as
`date_sent`, replacing the confusingly named `name` field. The
`date_sent` and `create_time` fields of attachment objects are now
encoded as integers; (previously the implementation could send
floats incorrectly suggesting that microsecond precision is
relevant).
* `GET /invites`: Now encodes the user ID of the person who created
the invitation as `invited_by_user_id`, replacing the previous
`ref` field (which had that user's Zulip display email address).
* [`POST /register`](/api/register-queue): The encoding of an
unlimited `realm_message_retention_days` in the response was changed
from `null` to `-1`.
**Feature level 21**
* `PATCH /settings/display`: Replaced the `night_mode` boolean with
`color_scheme` as part of supporting automatic night theme detection.
**Feature level 20**
* Added support for inviting users as organization owners to the
invitation endpoints.
**Feature level 19**
* [`GET /events`](/api/get-events): `subscriptions` event with
`op="peer_add"` and `op="peer_remove"` now identify the modified
stream by a `stream_id` field, replacing the old `name` field.
**Feature level 18**
* [`POST /register`](/api/register-queue): Added
`user_avatar_url_field_optional` to supported `client_capabilities`.
**Feature level 17**
* [`GET users/me/subscriptions`](/api/get-subscriptions),
[`GET /streams`](/api/get-streams): Added
`message_retention_days` to Stream objects.
* [`POST users/me/subscriptions`](/api/subscribe), [`PATCH
streams/{stream_id}`](/api/update-stream): Added `message_retention_days`
parameter.
**Feature level 16**
* [`GET /users/me`]: Removed `pointer` from the response, as the
"pointer" concept is being removed in Zulip.
* Changed the rendered HTML markup for mentioning a time to use the
`<time>` HTML tag. It is OK for clients to ignore the previous time
mention markup, as the feature was not advertised before this change.
**Feature level 15**
* Added [spoilers](/help/format-your-message-using-markdown#spoilers)
to supported Markdown features.
**Feature level 14**
* [`GET users/me/subscriptions`](/api/get-subscriptions): Removed
the `is_old_stream` field from Stream objects. This field was
always equivalent to `stream_weekly_traffic != null` on the same object.
**Feature level 13**
* [`POST /register`](/api/register-queue): Added
`bulk_message_deletion` to supported `client_capabilities`.
* [`GET /events`](/api/get-events): `message_deleted`
events have new behavior. The `sender` and `sender_id` fields were
removed, and the `message_id` field was replaced by a `message_ids`
list for clients with the `bulk_message_deletion` client capability.
All clients should upgrade; we expect `bulk_message_deletion` to be
required in the future.
**Feature level 12**
* [`GET users/{user_id}/subscriptions/{stream_id}`](/api/get-subscription-status):
New endpoint added for checking if another user is subscribed to a stream.
**Feature level 11**
* [`POST /register`](/api/register-queue): Added
`realm_community_topic_editing_limit_seconds` to the response, the
time limit before community topic editing is forbidden. A `null`
value means no limit. This was previously hard-coded in the server
as 86400 seconds (1 day).
* [`POST /register`](/api/register-queue): The response now contains a
`is_owner`, similar to the existing `is_admin` and `is_guest` fields.
* [`POST /set-typing-status`](/api/set-typing-status): Removed legacy support for sending email
addresses, rather than user IDs, to encode private message recipients.
**Feature level 10**
* [`GET users/me`](/api/get-own-user): Added `avatar_version`, `is_guest`,
`is_active`, `timezone`, and `date_joined` fields to the User objects.
* [`GET users/me`](/api/get-own-user): Removed `client_id` and `short_name`
from the response to this endpoint. These fields had no purpose and
were inconsistent with other API responses describing users.
**Feature level 9**
* [`POST users/me/subscriptions`](/api/subscribe), [`DELETE
/users/me/subscriptions`](/api/unsubscribe): Other users to
subscribe/unsubscribe, declared in the `principals` parameter, can
now be referenced by user_id, rather than Zulip display email
address.
* [PATCH /messages/{message_id}](/api/update-message): Added
`send_notification_to_old_thread` and
`send_notification_to_new_thread` optional parameters.
**Feature level 8**
* [`GET /users`](/api/get-users), [`GET /users/{user_id}`](/api/get-user)
and [`GET /users/me`](/api/get-own-user): User objects now contain the
`is_owner` field as well.
* Added [time mentions](/help/format-your-message-using-markdown#mention-a-time)
to supported Markdown features.
**Feature level 7**
* [`GET /events`](/api/get-events): `realm_user` and
`realm_bot` events no longer contain an `email` field to identify
the user; use the `user_id` field instead. Previously, some (but
not all) events of these types contained an `email` key in addition to
to `user_id`) for identifying the modified user.
* [`PATCH /users/{user_id}`](/api/update-user): The `is_admin` and
`is_guest` parameters were removed in favor of the more general
`role` parameter for specifying a change in user role.
* [`GET /events`](/api/get-events): `realm_user` events
sent when a user's role changes now include `role` property, instead
of the previous `is_guest` or `is_admin` booleans.
* `GET /realm/emoji`: The user who uploaded a given custom emoji is
now indicated by an `author_id` field, replacing a previous `author`
object with unnecessary additional data.
**Feature level 6**
* [`GET /events`](/api/get-events): `realm_user` events to
update a user's avatar now include the `avatar_version` field, which
is important for correctly refetching medium-size avatar images when
the user's avatar changes.
* [`GET /users`](/api/get-users) and [`GET
/users/{user_id}`](/api/get-user): User objects now contain the
`avatar_version` field as well.
**Feature level 5**
* [`GET /events`](/api/get-events): `realm_bot` events,
sent when changes are made to bot users, now contain an
integer-format `owner_id` field, replacing the `owner` field (which
was an email address).
**Feature level 4**
* `jitsi_server_url`, `development_environment`, `server_generation`,
`password_min_length`, `password_min_guesses`, `max_file_upload_size_mib`,
`max_avatar_file_size_mib`, `server_inline_image_preview`,
`server_inline_url_embed_preview`, `server_avatar_changes_disabled` and
`server_name_changes_disabled` fields are now available via
`POST /register` to make them accessible to all the clients;
they were only internally available to Zulip's web app prior to this.
**Feature level 3**:
* `zulip_version` and `zulip_feature_level` are always returned
in `POST /register`; previously they were only returned if `event_types`
included `zulip_version`.
* Added new `presence_enabled` user notification setting; previously
[presence](/help/status-and-availability) was always enabled.
**Feature level 2**:
* [`POST /messages/{message_id}/reactions`](/api/add-reaction):
The `reaction_type` parameter is optional; the server will guess the
`reaction_type` if it is not specified (checking custom emoji, then
Unicode emoji for any with the provided name).
* `reactions` objects returned by the API (both in `GET /messages` and
in `GET /events`) now include the user who reacted in a top-level
`user_id` field. The legacy `user` dictionary (which had
inconsistent format between those two endpoints) is deprecated.
**Feature level 1**:
* [`GET /server_settings`](/api/get-server-settings): Added
`zulip_feature_level`, which can be used by clients to detect which
of the features described in this changelog are supported.
* [`POST /register`](/api/register-queue): Added `zulip_feature_level`
to the response if `zulip_version` is among the requested
`event_types`.
* [`GET /users`](/api/get-users): User objects for bots now
contain a `bot_owner_id`, replacing the previous `bot_owner` field
(which had the email address of the bot owner).
* [`GET /users/{user_id}`](/api/get-user): Endpoint added.
* [`GET /messages`](/api/get-messages): Add support for string-format
values for the `anchor` parameter, deprecating and replacing the
`use_first_unread_anchor` parameter.
* [`GET /messages`](/api/get-messages) and [`GET
/events`](/api/get-events): Message objects now use
`topic_links` rather than `subject_links` to indicate links either
present in the topic or generated by linkifiers applied to the topic.
* [`POST /users/me/subscriptions`](/api/subscribe): Replaced
`is_announcement_only` boolean with `stream_post_policy` enum for
specifying who can post to a stream.
* [`PATCH /streams/{stream_id}`](/api/update-stream): Replaced
`is_announcement_only` boolean with `stream_post_policy` enum for
specifying who can post to a stream.
* [`GET /streams`](/api/get-streams): Replaced
`is_announcement_only` boolean with `stream_post_policy` enum for
specifying who can post to a stream.
* `GET /api/v1/user_uploads`: Added new endpoint for requesting a
temporary URL for an uploaded file that does not require
authentication to access (e.g. for passing from a Zulip desktop,
mobile, or terminal app to the user's default browser).
* Added `EMAIL_ADDRESS_VISIBILITY_NOBODY` possible value for
`email_address_visibility`.
* Added `private_message_policy` realm setting.
* `muted_topic` objects now are a 3-item tuple: (`stream_id`, `topic`,
`date_muted`). Previously, they were a 2-item tuple.
* `GitLab` authentication is now available.
* Added `None` as a video call provider option.
## Changes in Zulip 2.1
* [`GET /users`](/api/get-users): Added `include_custom_profile_fields`
to request custom profile field data.
* [`GET /users/me`](/api/get-own-user): Added `avatar_url` field,
containing the user's avatar URL, to the response.
* [`GET /users/me/subscriptions`](/api/get-subscriptions): Added
`include_subscribers` parameter controlling whether data on the
other subscribers is included. Previous behavior was to always send
subscriber data.
* [`GET /users/me/subscriptions`](/api/get-subscriptions):
Stream-level notification settings like `push_notifications` were
changed to be nullable boolean fields (true/false/null), with `null`
meaning that the stream inherits the organization-level default.
Previously, the only values were true/false. A client communicates
support for this feature using `client_capabilities`.
* [`GET /users/me/subscriptions`](/api/get-subscriptions): Added
`wildcard_mentions_notify` notification setting, with the same
global-plus-stream-level-override model as other notification settings.
* [`GET /server_settings`](/api/get-server-settings): Added
`external_authentication_methods` structure, used to display login
buttons nicely in the mobile apps.
* Added `first_message_id` field to Stream objects. This is helpful
for determining whether the stream has any messages older than a
window cached in a client.
* Added `is_web_public` field to Stream objects. This field is
intended to support web-public streams.
* Added `/export/realm` endpoints for triggering a data export.
* `PATCH /realm`: Added `invite_to_stream_policy`,
`create_stream_policy`, `digest_emails_enabled`, `digest_weekday`,
`user_group_edit_policy`, and `avatar_changes_disabled` organization settings.
* Added `fluid_layout_width`, `desktop_icon_count_display`, and
`demote_inactive_streams` display settings.
* `enable_stream_sounds` was renamed to
`enable_stream_audible_notifications`.
* Deprecated `in_home_view`, replacing it with the more readable
`is_muted` (with the opposite meaning).
* Custom profile fields: Added `EXTERNAL_ACCOUNT` field type.
## Changes in Zulip 2.0
* [`POST /messages`](/api/send-message): Added support for using user
IDs and stream IDs for specifying the recipients of a message.
* [`POST /messages`](/api/send-message), [`POST
/messages/{message_id}`](/api/update-message): Added support for
encoding topics using the `topic` parameter name. The previous
`subject` parameter name was deprecated but is still supported for
backwards-compatibility.
* [`POST /set-typing-status`](/api/set-typing-status): Added support for specifying the
recipients with user IDs, deprecating the original API of specifying
them using email addresses.
------------------
## Changes not yet stabilized
* [`POST /register`](/api/register-queue): Added `slim_presence`
parameter. Changes the format of presence events, but is still
being changed and should not be used by clients.
