We use the MaterMost docker image for detecting changes in the API. See
.travis.yml or the Mattermost
for the details.
If you are testing your changes locally during development, you will want to run
local_test_mm.sh script will stop and remove a docker container
Note: The tests can only be run once against a given Mattermost instance. This is because the scripts currently assume they can create an initial admin user.
Note: The scripts assume the instance is reachable on
localhost:8065 over plain
For use in production we use TLS, but for testing purposes we avoid the certificate setup.
Our Versioning Scheme
This library uses the same versioning scheme as
matterhorn, see Our
The short version is that in
ABBCC corresponds to Mattermost
A.BB.CC and the
X.Y portion of the version string corresponds
to the version of
mattermost-api package releases.
API changes: The postRootId of Post is now a Maybe PostId to better reflect the actual wire format. MinCommand now has fields for reply parent and root post IDs to support replying to posts with commands such as /me. CommandResponse's commandResponseType is now Maybe to permit optional types. PreferenceCategory got a new constructor, PreferenceCategoryLast, mapping to the "last" preference category. Added functions for bulk fetching for channel/user data: mmGetAllChannelsForUser mmGetAllChannelDataForUser mmGetAllChannelsWithDataForUser
Added support for the
emoji_added websocket event type.
WEData's JSON parser now permits both null and empty channel IDs.
Package changes: * Added lower bound for binary to avoid build failures in the websocket package on GHC 7.10 (see https://github.com/jaspervdj/websockets/pull/155)
* Added support for the
API changes: Added flagged posts API: Types: FlaggedPost mmGetFlaggedPosts mmFlagPost mmUnflagPost Added preferences API: Types: Preference, PreferenceCategory, PreferenceName, PreferenceValue mmDeletePreferences mmSavePreferences mmGetMyPreferences Added PostType for post types (joins, parts, header changes, etc.) and changed the type of Post.postType to use this new type. Added a new field WEData.wepMentions so that websocket events can include the set of UserIds in a mention set. Made most fields of PostPropAttachment optional. Added a new PostPropAttachment type as defined by Slack and used by Mattermost. Allow null for the "fields" field of PostPropAttachment. Extended PostPropAttachment with additional fields to better match the upstream spec.
Other changes: Improved the LoginFailureException message format. Refrain from logging passwords when logging login requests. * Logging operations seek to the end of the log in case of a shared log file.
This release supports server version 3.8.2.
Made the PendingPost
created_at field optional. It defaults to 0.
This behavior is due to Mattermost's support for admins setting the
creation timestamp to values in the past. A value of zero causes
the server to use the server's clock to set the creation timestamp.
Any other value is only permitted for users with administrative
Moved some types to a new Types.Internal module and exposed that
module for testing purposes. It should not be used by anyone wanting
a stable API. For a stable API, see the export list for the Types
This release supports server version 3.8.2.
Network.Mattermost.Types module is now directly exported and all
clients should obtain their types from this import. The types are
still exported from
Network.Mattermost to allow time for this change
but this export is deprecated will be removed in a future version.
Added the CommandResponse type for the execute endpoint.
mmGetMoreChannels, mmGetChannelMembers, and mmGetProfiles now take
mmGetFile now supports v4 file-fetching.
Added new constructors to the WebsocketEventType corresponding to
server websocket events.
mmUpdateLastViewedAt was replaced with mmViewChannel.
Added the WithDefault type to wrap around bools and NotifyOptions.
Added NotifyProps types.
Token type has been replaced with a
representing a combination of a
Token and a
type. All exposed API functions which require an authenticated
connection will use this instead. This is a major breaking change,
but makes the API significantly cleaner.
UserProfile type in favor of single pervasive
* Replaced the return type of
mmGetTeamMembers to use a
instead of raw JSON
Documentation: * All API functions how have corresponding HTTP route documentation.
Source repository was updated.
Constrained 'memory' version to avoid 'foundation' dependency.
Network.Mattermost.Websocket module now exports everything
Network.Mattermost.Websocket.Types in order to cut
down on the number of imports needed by users.
Supports server version 3.7.1.
Tests now provide websocket event testing infrastructure
The Channel data type now supports Group channels (type "G")
Added mmGetTeamMembers to get the users in a channel
Added support for the Post type
system_header_change and the post
old_header as described at
* Removed the UserProfile type in favor of the User type (fixed #23)
* WebSocket.Types: permit empty
team_id in event data
* Support optional
Package changes: * Renamed ChangeLog.md to CHANGELOG.md.
Testing changes: * Added support for testing websocket events and updated the test suite to check for expected websocket events.
API changes: * Export FileInfo type
Bug fixes: Fixed parsing of nullable width/height fields in FileInfo Fixed parsing of createat, updateat, and delete_at timestamp fields in FileInfo
API changes: Added mmDeletePost Added mmUpdatePost for editing posts Post: make deletion time optional to match server API, do millisecond conversion on JSON encoding PendingPost: add fields for setting parents in case of replies * Export PendingPost type so it can be modified for replies and edits
Bug fixes: * Post: do millisecond conversion of timestamps on JSON encoding
API changes: * MinCommand lost its unused minComSuggest field
Bug fixes: * The JSON format of MinCommand got its channelId field (3.5.0) renamed to channel_id (3.6.0). See also: https://github.com/mattermost/platform/issues/5281
Other: * mmGetJSONBody got a debugging label that it now uses to generate exception messages to indicate what kind of value it was attempting to parse.
Initial release for server version 3.6.0.
