Release 2023-01-12

Highlights

Calls

• An important change was made to calls participants limits. The Cloud free plan now supports up to 8 participants per call in group messages, public, or private channels (it was previously direct messages only).

• Audio calling and screen sharing in channels is now generally available to all Mattermost customers.

• The template picker has been improved to make it easier for users to find the best template for their project.

Playbooks

• Added an option to run playbooks without creating a new channel every time in order to reduce the unnecessary overhead.

• In addition to the daily digest, users can now also view a task inbox from the global header bar while in Playbooks.

Message Priority and Acknowledgments

• Added message priority labels to the Threads view.

• Added support for users to request acknowledgements on posts and to acknowledge posts (Professional license).

• Added a centralized Drafts view for draft messages.

ServiceNow Integration

• ServiceNow customers can now access and share their ServiceNow data from within Mattermost.

Improvements

User Interface (UI)

• Corrected in-product System Console legacy link to the Cloud Administrator’s Guide.

• Updated prepackaged NPS version to 1.3.1.

• Updated prepackaged version of Apps plugin to 1.2.0.

• Added group members count to the group autocomplete.

• Updated in-product confirmation modal for @here mentions to clarify that people & timezone counts don’t include the current user.

• Added support for multiple users and channels to the /invite slash command.

• Downgraded French language support to Beta.

Administration

• The export file now contains the server version and a creation timestamp.

• Plugins with a webapp component may need to be updated to work with Mattermost and the updated React v17 dependency. This is to avoid plugins crashing with an error about findDOMNode being called on an unmounted component. While our starter template <https://github.com/mattermost/mattermost-plugin-starter-template>_ depended on an external version of React, it did not do the same for ReactDOM. Plugins need to update their webpack.config.js directives to externalize ReactDOM. For reference, see https://github.com/mattermost/mattermost-plugin-playbooks/pull/1489. Server-side only plugins are unaffected. This change can be done for existing plugins any time prior to upgrading Mattermost and is backwards compatible with older versions of Mattermost.

• Compliance export job can now cancel the SQL query execution during server shutdown which will allow the job to exit faster.

• Shared Channels (Experimental) is now available with a Professional license.

• Removed Cloud Professional file storage limits.

• The message export compliance job can now survive server restarts. The job will pause and save state when the server is shutting down, and resume from the previously saved state when the server starts back up.

• Only one instance of the job will be automatically scheduled to run as per the MessageExportSettings.DailyRunTime config value.

• Mattermost will throw an error if it detects an Elasticsearch version greater than 7.

API Changes

Highlights

Apps Framework (Developer Preview)

• The Mattermost Apps Framework introduces a new way to integrate with external tools to allow developers to create interactive Apps in Mattermost using any development language they’re comfortable with. These Apps work seamlessly across mobile and desktop clients. This is a developer preview that is not yet intended for production instances of Mattermost. The Apps Framework will be available for self-managed customers in Mattermost v5.35 once the Apps Framework Plugin is loaded on an instance. Until then, developers can use the cloud branch to get a local test environment running. The launch for the Developer Preview of the Apps Framework is scheduled for April 29th, 2021. Learn more: https://developers.mattermost.com/integrate/apps/.

Search Results Are Returned on File Search

For example, fixed an issue where recently selected statuses were missing from the Set a Status confirmation screen, and updated the Mobile Push Notifications text in Account Settings to refer to user availability instead of online status.

• Moved the user status in the channel switcher to overlap with user avatars, and added URL ‘Slug’ information to channel names in the channel switcher.

Administration

• Paused admin advisor notifications from triggering.

Release 2021-04-07

Improvements

User Interface (UI)

• Added a string field to configuration for restricted domains with the key RestrictLinkPreviews and added a UI field for restricted domains under System Console > Site Configuration > Posts. Also expanded the logic that determines whether a post has a preview or not.

• Removed Beta tags from Swedish and Bulgarian languages.

• Added profile pictures to the Direct Messages channel list.

• Added channel icons for email notifications as part of email notification redesigns.

• Direct Messages More… modal is now sorted by recent conversations when the modal is opened.

• Removed legacy Open-Sans fonts and upgraded Open-Sans to v18.

Administration

• Removed the utility function model.GeneratePassword() for security reasons. An improved version is now being used internally to generate passwords for bulk-imported users.

• Only the System Admin is allowed to have the ability to assign system roles.

• Two new gauge metrics were added: mattermost_db_replica_lag_abs and mattermost_db_replica_lag_time, both containing a label of “node”, signifying which database host is the metric from.

  • These metrics signify the replica lag in absolute terms and in the time dimension capturing the whole picture of replica lag. To use these metrics, a separate config section ReplicaLagSettings was added under SqlSettings. This is an array of maps which contain three keys: DataSource, QueryAbsoluteLag, and QueryTimeLag. Each map entry is for a single replica instance. DataSource contains the database credentials to connect to the replica instance. QueryAbsoluteLag is a plain SQL query that must return a single row of which the first column must be the node value of the Prometheus metric, and the second column must be the value of the lag. QueryTimeLag is the same as above, but used to measure the time lag.

  • As an example, for AWS Aurora instances, the QueryAbsoluteLag can be: select server_id highest_lsn_rcvd-durable_lsn as bindiff from aurora_global_db_instance_status() where server_id=<> and QueryTimeLag can be: select server_id, visibility_lag_in_msec aurora_global_db_instance_status() where server_id=<>. For MySQL Group Replication, the absolute lag can be measured from the number of pending transactions in the applier queue: select member_id, count_transactions_remote_in_applier_queue FROM performance_schema.replication_group_member_stats where member_id=<>. Overall, what query to choose is left to the administrator, and depending on the database and need, an appropriate query can be chosen.

Bug Fixes

• Fixed an issue where users were unable to deactivate MFA for their accounts even if MFA was disabled on the server.

• Fixed an issue where user settings on API could be set if LDAP Sync was on. For LDAP and SAML users, the following fields cannot be changed via the API if the corresponding LDAP/SAML attributes have been set: first name, last name, position, nickname, email, profile picture. For OAUTH users (i.e., Gitlab, Google, Office365 and OpenID), the following fields cannot be changed via the API: first name, last name. All users who authenticate via a method other than email cannot change their username via the API.

• Fixed a possible panic on post creation when the collapsed threads feature was enabled.

• Fixed a database deadlock that could happen if a sidebar category was updated and deleted at the same time.

• Fixed an issue where the sidebar Text Hover BG Theme color didn’t work on the left-hand side.

• Fixed an issue where the Team Admin’s current role was presented inconsistently in the different areas of the System Console.

• Improved the websocket implementation by using epoll to manually read from a websocket connection. As a result, the number of goroutines is expected to go down by half.
