Important Upgrade Notes 

  • Insights has been deprecated for all new instances and for existing servers that upgrade to v8.0. See more details in this forum post on why Insights has been deprecated.

  • The Focalboard plugin is now disabled by default for all new instances and can be enabled in the System Console > Plugin settings.

  • The Channel Export and Apps plugins are now disabled by default.

  • Apps Bar is now enabled by default for on-prem servers. ExperimentalSettings.EnableAppBar was also renamed to ExperimentalSettings.DisableAppBar. See more details at:

    • https://docs.mattermost.com/configure/experimental-configuration-settings.html#disable-app-bar

    • https://forum.mattermost.com/t/channel-header-plugin-changes/13551

  • Introduced the public submodule, housing the familiar model and plugin packages, but now discretely versioned from the server. It is no longer necessary to go get a particular commit hash, as Go programs and plugins can now opt-in to importing github.com/mattermost/mattermost-server/server/public and managing versions idiomatically. While this submodule has not yet shipped a v1 and will introduce breaking changes before stabilizing the API, it remains both forwards and backwards compatible with the Mattermost server itself.

  • In the main server package, the Go module path has changed from github.com/mattermost/mattermost-server/server/v8 to github.com/mattermost/mattermost/server/v8. But with the introduction of the public submodule, it should no longer be necessary for third-party code to import this server package.

  • As part of the public submodule above, a context.Context is now passed to model.Client4 methods.

  • Removed support for PostgreSQL v10. The new minimum PostgreSQL version is now v11.

  • The Mattermost public API for Go is now available as a distinctly versioned package. Instead of pinning a particular commit hash, use idiomatic Go to add this package as a dependency: go get github.com/mattermost/mattermost-server/server/public. This relocated Go API maintains backwards compatibility with Mattermost v7. Furthermore, the existing Go API previously at github.com/mattermost/mattermost-server/v6/model remains forward compatible with Mattermost v8, but may not contain newer features. Plugins do not need to be recompiled, but developers may opt in to using the new package to simplify their build process. The new public package is shipping alongside Mattermost v8 as version 0.5.0 to allow for some additional code refactoring before releasing as v1 later this year.

  • Three configuration fields have been added, LogSettings.AdvancedLoggingJSON, ExperimentalAuditSettings.AdvancedLoggingJSON, and NotificationLogSettings.AdvancedLoggingJSON which support multi-line JSON, escaped JSON as a string, or a filename that points to a file containing JSON. The AdvancedLoggingConfig fields have been deprecated.

  • The Go MySQL driver has changed the maxAllowedPacket size from 4MiB to 64MiB. This is to make it consistent with the change in the server side default value from MySQL 5.7 to MySQL 8.0. If your max_allowed_packet setting is not 64MiB, then please update the MySQL config DSN with an additional param of maxAllowedPacket to match with the server side value. Alternatively, a value of 0 can be set to to automatically fetch the server side value, on every new connection, which has a performance overhead.

  • Removed ExperimentalSettings.PatchPluginsReactDOM. If this setting was previously enabled, confirm that:

    1. All Mattermost-supported plugins are updated to the latest versions.

    2. Any other plugins have been updated to support React 17. See the Important Upgrade Notes for v7.7 for more information.

  • Removed deprecated PermissionUseSlashCommands.

  • Removed deprecated model.CommandArgs.Session.

  • Pass a context.Context to Client4 methods.

  • For servers wanting to allow websockets to connect from origins other than the origin of the site URL, please set the ServiceSettings.AllowCorsFrom configuration setting. Also ensure that the siteURL is set correctly.

  • In v8.0, the following repositories are merged into one: mattermost-server, mattermost-webapp and mmctl. Developers should read the updated Developer Guide for details.

  • Fixed an issue caused by a migration in the previous release. Query takes around 11ms on a PostgreSQL 14 DB t3.medium RDS instance. Locks on the preferences table will only be acquired if there are rows to delete, but the time taken is negligible.

  • Fixed an issue where a user would still see threads in the threads view of channels they have left. Migration execution time in PostgreSQL: Execution time: 58.11 sec, DELETE 2766690. Migration execution time in MySQL: Query OK, 2766769 rows affected (4 min 47.57 sec).

  • The file info stats query is now optimized by denormalizing the channelID column into the table itself. This will speed up the query to get the file count for a channel when selecting the right-hand pane. Migration times:

    • On a PostgreSQL 12.14 DB with 1731 rows in FileInfo and 11M posts, it took around 0.27s

    • On a MySQL 8.0.31 DB with 1405 rows in FileInfo and 11M posts, it took around 0.3s

IMPORTANT: If you upgrade from a release earlier than v7.10, please read the other Important Upgrade Notes.

Important Upgrade Notes 

  • Added a new index on Posts(OriginalId). For a database with 11.8 million posts, on a machine with a i7-11800H CPU (8 cores, 16 threads), 32GiB of RAM and SSD, the index creation takes 98.51s on MYSQL and 2.6s on PostgreSQL.

  • In PostgreSQL databases, the Posts table will be locked during index creation. To avoid locking this table, admins can create the index manually before performing the upgrade using the following non-blocking query: CREATE INDEX CONCURRENTLY idx_posts_original_id ON Posts(OriginalId);.

  • Admins managing PostgreSQL deployments containing fewer posts may prefer that the migration process creates the index, and accept that Posts table will remain locked until the migration is complete.

    • Original 7.7.0 release

Mattermost v7.7.0 contains low severity level security fixes. Upgrading to this release is recommended. Details will be posted on our security updates page 30 days after release as per the Mattermost Responsible Disclosure Policy.

Important Upgrade Notes 

  • Plugins with a webapp component may need to be updated to work with Mattermost v7.7 release 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 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 to Mattermost v7.7 and is backwards compatible with older versions of Mattermost. If you run into issues, you can either enable ExperimentalSettings.PatchPluginsReactDOM or just disable the affected plugin while it’s updated.

  • Denormalized Threads table by adding the ThreadTeamId column. See details for schema changes in the Important Upgrade Notes.

  • Starting with the Calls version shipping with v7.7, there’s now a minimum version requirement when using the external RTCD service. This means that if Calls is configured to use the external service, customers need to upgrade RTCD first to at least version 0.8.0 or the plugin will fail to start.

IMPORTANT: If you upgrade from a release earlier than v7.5, please read the other Important Upgrade Notes.

Compatibility 

  • Updated the minimum version of MacOS to 11+.

Highlights 

Calls 

Boards 

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).

Global Drafts 

ServiceNow Integration 

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

ServiceNow Virtual Agent Integration 

GitLab Playbooks Integration 

Improvements 

User Interface (UI) 

  • Implemented progressive image loading in the webapp.

  • When the “Custom Brand Text” is left blank with custom branding enabled, the default text is now hidden.

  • The Mark as Unread option was added to the More (…) menu for channels in the left-hand side sidebar. Pressing Alt while selecting a channel on the left-hand side now also marks the last post in the channel as unread.

  • Channel members are now able to remove themselves from a channel via the right-hand side channel members list.

  • Removed video check to allow the browser to decide what video types it can play.

  • Added a tooltip to the right-hand side files filter icon.

  • The number of users that can be added to a user group at once was increased to 256.

  • Keyboard and focus handling was improved in profile popovers and @mentions.

Administration

  • Crashing jobs now sets the job status to “failed”.

  • Optimized ThreadStore.MarkAllAsUnreadByTeam.

  • SQL migrations for PostgreSQL will now filter by the current schema name when checking for information from the information_schema.columns view. This does not affect anything because usually there’s only one installation in a given database, but this gives flexibility to users to store multiple Mattermost instances under a single database.

  • My Insights was added to the Free plan.

  • Team scheme APIs are now allowed to be administered with a Professional plan.

  • A global banner as well as a notice banner are displayed to admins on the Invite modal and on System Console > Site Statistics > Total Activated Users page when the workspace exceeds the maximum number of users allowed. If the number of actual users exceeds the number of paid users by less than 5%, the banner is dismissible. If the number of actual users exceeds the number of paid users by more than 10%, the banner is non-dismissible until the license seat count has been updated.

  • For admins to see if the amount of users exceeds the license seats, a warning is now shown in the System Console > Team Statistics page.

  • Added a new menu item on the System Console > Users page that re-adds users to all of their default teams and channels associated with the groups they’re a member of.

  • Added acknowledgements field to the post’s metadata.

  • Added support for product websocket messages on high availability instances.

  • The import job now logs the progress of the import.

IMPORTANT: If you upgrade from a release earlier than v7.2, please read the other Important Upgrade Notes.

Mattermost v7.1.0 contains low severity level security fixes. Upgrading to this release is recommended. Details will be posted on our security updates page 30 days after release as per the Mattermost Responsible Disclosure Policy.

Important Upgrade Notes 

  • A new configuration option MaxImageDecoderConcurrency indicates how many images can be decoded concurrently at once. The default is -1, and the value indicates the number of CPUs present. This affects the total memory consumption of the server. The maximum memory of a single image is dictated by MaxImageResolution * 24 bytes. Therefore, we recommend that MaxImageResolution * MaxImageDecoderConcurrency * 24 should be less than the allocated memory for image decoding.

  • Mattermost v7.1 introduces schema changes in the form of a new column and its index. The following notes our test results for the schema changes:

    • MySQL 12M Posts, 2.5M Reactions - ~1min 34s (instance: PC with 8 cores, 16GB RAM)

    • PostgreSQL 12M Posts, 2.5M Reactions - ~1min 18s (instance: db.r5.2xlarge)

  • You can run the following SQL queries before the upgrade to obtain a lock on Reactions table, so that users’ reactions posted during this time won’t be reflected in the database until the migrations are complete. This is fully backwards-compatible.

    • For MySQL:

      • ALTER TABLE Reactions ADD COLUMN ChannelId varchar(26) NOT NULL DEFAULT "";

      • UPDATE Reactions SET ChannelId = COALESCE((select ChannelId from Posts where Posts.Id = Reactions.PostId), '') WHERE ChannelId="";

      • CREATE INDEX idx_reactions_channel_id ON Reactions(ChannelId) LOCK=NONE;

    • For PostgreSQL:

      • ALTER TABLE reactions ADD COLUMN IF NOT EXISTS channelid varchar(26) NOT NULL DEFAULT '';

      • UPDATE reactions SET channelid = COALESCE((select channelid from posts where posts.id = reactions.postid), '') WHERE channelid='';

      • CREATE INDEX CONCURRENTLY IF NOT EXISTS idx_reactions_channel_id on reactions (channelid);

IMPORTANT: If you upgrade from a release earlier than v7.0, please read the other Important Upgrade Notes.
