90000.1.1

Bug fixes:

• The EnableSignUpWithGitLab field of ClientConfig is now optional using Maybe since some servers do not provide it. Prior to this change, the library would fail to decode the ClientConfig completely if the field was missing.

90000.1.0

API changes:

• The clientConfigRestrictDirectMessage field of ClientConfig is now optional (as a Maybe) in order to more accurately reflect configurations found in the wild.

Other changes:

• Raised upper bound on aeson to 2.3.

90000.0.0

Package changes:

• Updated the package to use crypton-connection since connection is now unmaintained.

API changes:

• Updated the ChannelMember type's channelMemberMsgCount field to have type Int, not Integer, to match all other numeric types in the API.
• Added support for multiple_channels_viewed websocket event added in Mattermost 9.0.

50200.15.0

API changes:

• The Post data type got a new postMetadata field of type PostMetadata which carries the metadata JSON data that the server provides in API responses. As of this implementation, only the file list (files) and reactions (reactions) are parsed from the post metdata.

50200.14.0

Package changes:

• Updated to build with mtl-2.3.* (thanks Ryan Scott)

50200.13.0

API changes:

• Added a wepParentId field to WEData and parsed parent_id in its JSON representation.

50200.12.0

Package changes:

• Changed Aeson dependency to 2.0 to support GHC 9.

New features:

• 2FA support (thanks @msm-code)

50200.11.0

API changes: (Thanks Ajay Eeralla)

• Added a new constructor PreferenceCategoryFavoriteChannel to the PreferenceCategory type and updated its JSON parser to recognize this category.
• Added a FavoriteChannelPreference type and preferenceToFavoriteChannelPreference smart constructor.

Other changes:

• Logging now uses show, not toJSON, for values to be logged. This changes the logging functionality to use simple Show instances instead of first converting internal data types back to AESON structures. That wasn't really providing any additional value, and the extra conversion was producing at least one inconsistency due to an unfinished ToJSON implementation. (Thanks to Karl Smeltzer (@karljs))

50200.10.0

API changes:

• Types got constructors for Preference values
• Types got a new PreferenceCategoryTeamsOrder constructor for PreferenceCategory

50200.9.0

API changes:

• Added Network.Mattermost.Types.Internal.connectionDataURL and its return type, ServerBaseURL, to obtain base URLs corresponding to a connection handle.

50200.8.0

API changes:

• Added a WMUnknownEvent constructor to the WebsocketEventType data type to hold unknown event types to avoid parse failures for new event types.
• Added mmListCommandsForTeam to get commands for a team and implemented a JSON parser for the Command type.

Package changes:

• Upgraded to HTTP 4000.3.15 to get an Eq instance fix for HTTP header name comparisons.

50200.7.0

• Added mmUpdateChannelNotifications and fixed the JSON encoding of the ChannelNotifyProps type.

50200.6.0

API changes:

• Version 4 API functions now all have the potential to raise a new exception type, RateLimitExceptions, when HTTP 429 (rate limiting) responses are received. The new exception type provides rate limit metadata received from the server so the caller can determine whether to attempt a request again, and how long to wait before attempting it.
• The ChannelNotifyProps type got a new channelNotifyPropsIgnoreChannelMentions field.
• The WEData type got a wepChannelMember field.

Other changes:

• channel_member_updated websocket events are now parsed.
• Some haddock syntax errors were fixed (thanks Eric Mertens)

50200.5.0

API changes:

• Added support for making connections to Mattermost servers that use non-root URL paths for their API endpoints. This change adds a new field, cdUrlPath, to the ConnectionData type. It also added a URL path argument of type Text to mkConnectionData. (Thanks Isaiah Mindich)
• Added Network.Mattermost.Endpoints.mmGetLimitedClientConfiguration (thanks Eric Mertens)

50200.4.0

• The post pinning API is now supported.

  • Adds a new postPinned field to the Post type to allow parsing "is_pinned" values in post editing websocket events. Typically "is_pinned" is not present in post structures, in which case this will take the value Nothing.
  • Exposes the new StatusOK type that is returned by new API functions.
  • Adds new API functions:
    • mmPinPostToChannel
    • mmUnpinPostToChannel
    • mmGetChannelPinnedPosts

• The library now supports connecting to HTTPS endpoints without valid certificates.

  This change gets rid of the initConnectionDataInsecure function and instead makes initConnectionData take a new argument of type 'ConnectionType' that describes how the connection should be made.

  The ConnectionType type indicates that a connection should be HTTP, HTTPS with cert validation, or HTTPS without cert validation.

  This change also modified ConnectionData to carry the connecion type rather than just a Bool indicating HTTP/HTTPS.

• Websocket action responses are now parsed properly.

  Websocket actions, such as "user typing" notifications, generate server responses that we previously could not parse. We weren't parsing them because the parser for websocket events wasn't aware of an alternative response message structure. This patch adds a new type for action responses. It adds a new type rather than adding a new constructor to the event type because I think that's a less ugly API (the API in this patch is not ideal). This patch also adds logic to the websocket response parser to first attempt to parse incoming messages as websocket events (the most common case) and then fall back to attempting a parse as a websocket action response. If both fail, the message and the parse exceptions are all logged.

50200.3.0

Bug fixes:

• Fixed a bug in the Team JSON decoder where the invite_id field was required despite it truly being optional (see also https://github.com/matterhorn-chat/matterhorn/issues/550)

50200.2.0

API changes:

• Added Network.Mattermost.Endpoints.mmDeleteReaction to delete reactions.
• Added Network.Mattermost.Endpoints.mmPostReaction to add reactions.
• Added an Emoji data type and functions for custom emoji search and listing:
  • Network.Mattermost.Endpoints.mmSearchCustomEmoji
  • Network.Mattermost.Endpoints.mmGetListOfCustomEmoji

New features:

• Add support for SOCKS proxies via standard environment variables HTTPS_PROXY and ALL_PROXY.
• Support NO_PROXY to blacklist proxied hosts.

50200.1.4

Bug fixes:

• Content-type headers in server API responses are now parsed correctly in the presence of media type parameters as per RFC 2616.

50200.1.3

API changes:

• The PostProps type got support for the from_webhook prop

50200.1.2

Bug fixes:

• The server response to an uploaded file may report "null" for client_ids. This previously failed the parse attempt to create a Seq ClientId; this fix updates to conver null to an empty Seq. This typically manifested in attempting to attach a file in a common channel.

Compatibility:

• Updated supported/tested GHC versions: 8.2.2, 8.4.4, and 8.6.3.

50200.1.1

Bug fixes:

• The userCreateAt, userUpdateAt, and userAuthData fields of User are now permitted to be optional in the user JSON encoding to be consistent with the server.

50200.1.0

• Added mmUploadFile and exposed its UploadResponse result type.
• Fixed the FileInfo JSON decoder to permit post_id to be omitted.
• Added RestrictDirectMessageSetting data type for clientConfigRestrictDirectMessage field of ClientConfig.
• Added mmAutocompleteUsers.
• Added mmAutocompleteChannels.
• Added DirectChannelShowStatus preference type and constructor.

Bug fixes:

• mkQueryString now properly URI-encodes keys and values.

50200.0.1

Bug fixes:

• Fix the specification of the QuerySince time for fetching channel posts. The previous version generated a user-displayable date-time which contained spaces and created a malformed URL as well as not being in the proper format for the server.

50200.0.0

API changes:

• Expose new type, TeammateNameDisplayMode, as the type of the clientConfigTeammateNameDisplay field
• Removed various fields from TeamSettings and ClientConfig that seem to have been removed in 4.9
• Remove parent_id fields from Post and PendingPost since they are unused and thus confusing
• Added basic parsing support for websocket events new in 5.2 (fixes #408)
• ClientConfig: removed EnableUserCreation field that is removed in 5.0
• Removed extra_update_at channel data field

Bug fixes:

• Fixed examples and tests to use the UserText type instead of Data.Text (thanks Carlos D m@cdagostino.io)

40900.1.0

API changes:

• Added a newtype, UserText, to wrap many API response fields to indicate that they may contain unsafe or unsanitized user input. Also added unsafeUserText to unwrap such values when the caller knows that using the unsafe value is appropriate.

40900.0.0

• Endpoints: enabled mmPatchPost and removed duplicate argument type for PostUpdate.
• Ensure that file fetching uses the V4 API endpoint.

40800.0.2

• The websocket connection now uses the V4 API endpoint.
• submitRequest now also retries on "resource vanished" exceptions.

40800.0.1

• createPool now requires a secure connection argument. Previously it always defaulted to True which broke insecure connection setups.
• Removed the upper bound from memory to support GHC 8.4.

40800.0.0

• Fixed the URI for the mmUnflagPost API call.
• Some JSON instances now more precisely handle missing optional fields.
• mattermost-api now supports connection pooling with persistent server connections. A connection pool configuration is required to connect to Mattermost servers (thanks to Abhinav Sarkar)

40700.0.0

API changes:

• Added a websocket event constructor for the delete_team event added in 4.7.

40600.1.0

API changes:

• The UserSearch type now wraps optional fields with Maybe. The field types changed from Text to the appropriate ID type.
• Removed defunct Network.Mattermost.Types.mkSession function.
• Added an API endpoint function mmGetUsersByIds for getting users by ID.

Other changes:

• The doRequest function used by APIv4 endpoint functions now invokes the connection's logger to log request method and URI.

40600.0.0

API changes:

• This release provides implementations of many of Mattermost's version 4 API endpoints in the new Network.Mattermost.Endpoints module. The old version 3 API is still provided by Network.Mattermost but will be deprecated in a future release, and removed after that. Note that this release chiefly exposes version 4 endpoints used by the Matterhorn application; endpoints not used there have not been tested and so are left commented out in this release and may be enabled in future releases as needed.
• This release also provides first-class Haskell types corresponding to the server-side configuration; see Network.Mattermost.Types.Config.
• The Post data type got a new postEditAt field corresponding to the (at the time) undocumented edit_at field of posts.
• Websockets got action support; see Network.Mattermost.WebSocket.mmSendWSAction and the new WebsocketAction type (thanks to Abhinav Sarkar for this change)
• All UTCTimes received from the Mattermost server are wrapped in a ServerTime newtype to ensure that users cannot accidentally compare such timestamps to local UTCTimes, since the server time is not necessarily comparable.
• Added Network.Mattermost.Endpoints.mmGetClientConfig to get the client configuration from the server (Thanks to Kelly McLaughlin for this change)

40400.0.0

API changes:

• Added endpoints for some preference endpoints, group channels, and post search:
  • mmChannelRemoveUser
  • mmCreateGroupChannel
  • mmSearchPosts
  • mmSetPreferences
• Added GroupChannelPreferences type for showing/hiding group channels
• Separated the previous NotifyProps type into UserNotifyProps and ChannelNotifyProps.
• Websocket parse failures are now captured and appear to the library user as an Either String WebsocketEvent, where the String represent a parse failure.
• Add support for user_role_updated websocket event type.

40000.1.0

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

40000.0.1

API changes:

• Added support for the emoji_added websocket event type.
• WEData's JSON parser now permits both null and empty channel IDs.

40000.0.0

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)

API changes:

• Added support for the channel_viewed and channel_updated websocket events

31000.0.0

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.

30802.1.0

This release supports server version 3.8.2.

API changes:

• 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 privileges.
• 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 module.

30802.0.0

This release supports server version 3.8.2.

API changes:

• The 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 limit/offset parameters.
• 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.
• The Token type has been replaced with a Session type, representing a combination of a Token and a ConnectionData 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.
• Removed UserProfile type in favor of single pervasive User type.
• Replaced the return type of mmGetTeamMembers to use a TeamMember instead of raw JSON Values.

Documentation:

• All API functions how have corresponding HTTP route documentation.

Package changes:

• Source repository was updated.
• Constrained 'memory' version to avoid 'foundation' dependency.
• Include Network.Mattermost.TH.
• The Network.Mattermost.Websocket module now exports everything exported by Network.Mattermost.Websocket.Types in order to cut down on the number of imports needed by users.

30701.0.0

• Supports server version 3.7.1.

API changes:

• 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 properties new_header and old_header as described at https://github.com/mattermost/platform/pull/4209
• Removed the UserProfile type in favor of the User type (fixed #23)

Bug fixes:

• WebSocket.Types: permit empty team_id in event data

30600.2.2

Bug fixes:

• Support optional notify_props and last_password_update in mmGetUser responses.

Package changes:

• Renamed ChangeLog.md to CHANGELOG.md.

Testing changes:

API changes:

• Export FileInfo type

Bug fixes:

• Fixed parsing of nullable width/height fields in FileInfo
• Fixed parsing of create_at, update_at, and delete_at timestamp fields in FileInfo

30600.2.0

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

30600.1.0

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.

30600.0.0

Initial release for server version 3.6.0.
