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 toExperimentalSettings.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
andplugin
packages, but now discretely versioned from the server. It is no longer necessary togo get
a particular commit hash, as Go programs and plugins can now opt-in to importinggithub.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 fromgithub.com/mattermost/mattermost-server/server/v8
togithub.com/mattermost/mattermost/server/v8
. But with the introduction of thepublic
submodule, it should no longer be necessary for third-party code to import thisserver
package.As part of the
public
submodule above, acontext.Context
is now passed tomodel.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
, andNotificationLogSettings.AdvancedLoggingJSON
which support multi-line JSON, escaped JSON as a string, or a filename that points to a file containing JSON. TheAdvancedLoggingConfig
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 yourmax_allowed_packet
setting is not 64MiB, then please update the MySQL config DSN with an additional param ofmaxAllowedPacket
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:All Mattermost-supported plugins are updated to the latest versions.
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 thesiteURL
is set correctly.In v8.0, the following repositories are merged into one:
mattermost-server
,mattermost-webapp
andmmctl
. 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.

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 ofReact
, it did not do the same forReactDOM
. Plugins need to update theirwebpack.config.js
directives to externalizeReactDOM
. 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 enableExperimentalSettings.PatchPluginsReactDOM
or just disable the affected plugin while it’s updated.
Denormalized
Threads
table by adding theThreadTeamId
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.

ThreadStore.MarkAllAsUnreadByTeam
.SQL migrations for PostgreSQL will now filter by the current schema name when checking for information from the

Boards linked to a channel you’re a member of do not automatically appear on your sidebar unless you’re an explicit member of the board. As a workaround, you can access the board from the channel RHS or by searching for the board via the board switcher (Ctrl/Cmd+K). Alternatively, you can ask the board admin to add you to the board as an explicit member. See the issue-focalboard-4179 for more details.
The Playbooks left-hand sidebar does not update when a user is added to a run or playbook without a refresh.

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 byMaxImageResolution * 24 bytes
. Therefore, we recommend thatMaxImageResolution * 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.

v7.0.1, released 2022-06-24
Fixed an issue where mmctl checked the server version incorrectly MM-45161.
Fixed an issue where the file icon was sometimes unresponsive MM-45097.
Fixed an issue with Compliance Exports where the zip file creation failed when adding attachments to a post MM-40179.

Important Upgrade Notes#
IMPORTANT: Session length configuration settings have changed from using a unit of days to hours. Instances using a config.json file or a database configuration for the following values should be automatically migrated to the new units, but instances using environment variables must make the following changes:
replace
MM_SERVICESETTINGS_SESSIONLENGTHWEBINDAYS
withMM_SERVICESETTINGS_SESSIONLENGTHWEBINHOURS
(x24 the value).replace
MM_SERVICESETTINGS_SESSIONLENGTHMOBILEINDAYS
withMM_SERVICESETTINGS_SESSIONLENGTHMOBILEINHOURS
(x24 the value).replace
MM_SERVICESETTINGS_SESSIONLENGTHSSOINDAYS
withMM_SERVICESETTINGS_SESSIONLENGTHSSOINHOURS
(x24 the value).
MySQL self-hosted customers may notice the migration taking longer than usual when having a large number of rows in the
FileInfo
table. For MySQL, it takes around 19 seconds for a table of size 700,000 rows. The time required for PostgreSQL is negligible. The testing was performed on a machine with specifications ofCPU - Intel i7 6-cores @ 2.6 GHz
andMemory - 16 GB
.When a new configuration setting via System Console > Experimental > Features > Enable App Bar is enabled, all channel header icons registered by plugins will be moved to the new Apps Bar, even if they do not explicitly use the new registry function to render a component there. The setting for Apps Bar defaults to
false
for self-hosted deployments.The value of
ServiceSettings.TrustedProxyIPHeader
defaults to empty from now on. A previous bug prevented this from happening in certain conditions. Customers are requested to check for these values in their config and set them to nil if necessary. See more details here.Upgrading the Microsoft Teams Calling plugin to v2.0.0 requires users to reconnect their accounts.

Native voice calling and screen sharing is now available. This is a Channels-specific integration.
Apps Bar (Beta)#
Channel header is now decluttered when a new configuration setting via System Console > Experimental > Features > Enable App Bar is enabled, to make it more obvious how to access Calls, Playbooks, and Boards when viewing a channel. All channel header icons registered by plugins will be moved to the new Apps Bar when the configuration setting is enabled, while Calls remains in the channel header. We recommend enabling the Apps Bar for servers with Calls enabled since the Apps Bar helps make space for the dedicated Start Call button in the channel header.
Playbooks Updates#
Users can now easily keep processes up-to-date with the inline playbook editor.
A new statistics dashboard was added that displays the number of playbooks and run instances within the server alongside other system statistics in the System Console.
Run triggers and actions now provide more control over where status updates are posted throughout a run.
Message Formatting Toolbar#
The new formatting toolbar makes Markdown accessible to everyone with easy to use controls for commonly used message formatting, such as bold, headings, links, and more.
Improvements#
User Interface (UI)#
For toggling the channel information in the right-hand pane, a shortcut CTRL/CMD+ALT+I was added.
Added an “Unread Channels” section to the channel switcher and included threads in the results.
Users are no longer hidden from search results in the “Add members” modal, even if they are already members of the channel.
Applied new designs for the Login screen.
Enabled the new onboarding task list for end users.
The legacy Settings > Advanced Settings > Preview Pre-release Features setting is now deprecated in favor of the the new formatting toolbar.
Romanian language support was downgraded to Beta.
Performance#
Improved the performance of aggregate queries related to Collapsed Reply Threads. Learn more about these server performance optimizations in this article.
Integrations#
To keep users in Mattermost when opening documentation links from the System Console > Plugin settings page, all the links now open in another tab.
Changed Actions post menu hover text to Message Actions.
Updated Apps Framework to version 1.1.0 to add improved logging.
Administration#
Timestamps are now enabled in the default audit configuration.
The Collapsed Reply Threads configuration option was moved in the System Console from Experimental to Site Configuration > Posts.
Enterprise Subscription#
Upgraded the minor version of the ElasticSearch development Docker image.
The Support Packet now contains two additional fields in the
support_packet.yaml
file: Active users and License-supported users.

Release v6.7 - Feature Release#
v6.7.2, released 2022-06-15
Fixed an issue with Compliance Exports where the zip file creation failed when adding attachments to a post MM-40179.
v6.7.1, released 2022-06-13
Mattermost v6.7.1 contains medium 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.
The value of
ServiceSettings.TrustedProxyIPHeader
defaults to empty from now on. A previous bug prevented this from happening in certain conditions. Customers are requested to check for these values in their config and set them to nil if necessary. See more details here.
v6.7.0, released 2022-05-16
Original 6.7.0 release
Mattermost v6.7.0 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.
Compatibility#
Updated Chrome recommended minimum version to v100+.
Important Upgrade Notes#
New schema changes were introduced in the form of a new index. The following summarizes the test results measuring how long it took for the database queries to run with these schema changes:
MySQL 7M Posts - ~17s (Instance: db.r5.xlarge)
MySQL 9M Posts - 2min 12s (Instance: db.r5.large)
Postgres 7M Posts - ~9s (Instance: db.r5.xlarge)
For customers wanting a zero downtime upgrade, they are encouraged to apply this index prior to doing the upgrade. This is fully backwards compatible and will not acquire any table lock or affect any existing operations on the table when run manually. Else, the queries will run during the upgrade process and will lock the table in non-MySQL environments. Run the following to apply this index:
For MySQL:
CREATE INDEX idx_posts_create_at_id on Posts(CreateAt, Id) LOCK=NONE;
For Postgres:
CREATE INDEX CONCURRENTLY IF NOT EXISTS idx_posts_create_at_id on posts(createat, id);
Important
If you upgrade from a release earlier than v6.6, please read the other Important Upgrade Notes.

Original 6.4.0 release
Mattermost v6.4.0 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 schema migration system has been introduced, so we strongly recommend backing up the database before updating the server to this version. The new migration system will run through all existing migrations to record them to a new table. This will only happen for the first run in order to migrate the application to the new system. The table where migration information is stored is called
db_migrations
. Additionally, adb_lock
table is used to prevent multiple installations from running migrations in parallel. Any downtime depends on how many records the database has and whether there are missing migrations in the schema. In case of an error while applying the migrations, please check this table first. If you encounter an issue please file an Issue by including the failing migration name, database driver/version, and the server logs.On MySQL, if you encounter an error “Failed to apply database migrations” when upgrading to v6.4.0, it means that there is a mismatch between the table collation and the default database collation. You can manually fix this by changing the database collation with
ALTER DATABASE <YOUR_DB_NAME> COLLATE = 'utf8mb4_general_ci',
. Then do the server upgrade again and the migration will be successful.It has been commonly observed on MySQL 8+ systems to have an error
Error 1267: Illegal mix of collations
when upgrading due to changing the default collation. This is caused by the database and the tables having different collations. If you get this error, please change the collations to have the same value with, for example,ALTER DATABASE <db_name> COLLATE = '<collation>'
.The new migration system requires the MySQL database user to have additional EXECUTE, CREATE ROUTINE, ALTER ROUTINE and REFERENCES privileges to run schema migrations.
Important
If you upgrade from a release earlier than v6.3, please read the other Important Upgrade Notes.
Highlights#
Playbook Updates#
The Team and Starter plans no longer have a limit to the number of playbooks that can be created.

Important Upgrade Notes#
Channel results in the channel autocomplete will include private channels. Customers using Bleve or Elasticsearch for autocomplete will have to reindex their data to get the new results. Since this can take a long time, we suggest disabling autocomplete and running indexing in the background. When this is complete, re-enable autocomplete. Note that only channel members will see private channel names in autocomplete results.
Collapsed Reply Threads, available in beta, are known to have a negative impact on server performance. If you cannot easily scale up and tune your database, or if you are running the Mattermost application server and database server on the same machine, we recommended disabling
ThreadAutoFollow
andCollapsedThreads
until Collapsed Reply Threads is promoted to general availability in Q2 2022. Learn more about these performance considerations here.

Mattermost v6.1.0 contains low 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#
Please refer to the schema migration analysis when upgrading to v6.1.
The Bleve index has been updated to use the scorch index type. This new default index type features some efficiency improvements which means that the indexes use significantly less disk space. To use this new type of index, after upgrading the server version, run a purge operation and then a reindex from the Bleve section of the System Console. Bleve is still compatible with the old indexes, so the currently indexed data will work fine if the purge and reindex is not run.
A composite index has been added to the jobs table for better query performance. For some customers with a large jobs table, this can take a long time, so we recommend adding the index during off-hours, and then running the migration. A table with more than 1 million rows can be considered as large enough to be updated prior to the upgrade.
For PostgreSQL:
create index concurrently idx_jobs_status_type on jobs (status,type);
For MySQL:
create index idx_jobs_status_type on Jobs (Status,Type);

v6.0.0, released 2021-10-13
Original 6.0.0 release
Deprecations#
Legacy Command Line Tools. Most commands have been replaced by mmctl and new commands have been added over the last few months, making this tool a robust replacement.
Slack Import via the web app. The Slack import tool accessible via the Team Setting menu has been replaced by the mmetl tool that is much more comprehensive for the types of data it can assist in uploading.
MySQL versions below 5.7.12. Minimum support is now for 5.7.12+. This version introduced a native JSON data type that lets us improve performance and scalability of several database fields (most notably Users and Posts props). Additionally, version 5.6 (our current minimum version) reached EOL in February 2021.
Elasticsearch 5 and 6 - versions 5.x reached EOL in March of 2019, and versions 6.x reached EOL in November 2020. Our minimal supported version with Mattermost v6.0 is Elasticsearch version 7.0.
Windows 7 reached EOL in January 2020. We no longer provide support for Mattermost Desktop App issues on Windows 7.
DisableLegacyMFAEndpoint configuration setting.
ExperimentalTimezone configuration setting. The config setting is removed and the feature is promoted to general availability.
All legacy channel sidebar experimental configuration settings. We encourage customers using these settings to upgrade to v5.32 or later to access custom, collapsible channel categories among many other channel organization features. The deprecated settings include:
ExperimentalTownSquareIsReadOnly (Please see channel moderation settings, which allow you to set any channel as read-only, including Town Square)
All configuration settings previously marked as “Deprecated”.
Changes to
mattermost-server/model
for naming consistency.
Important Upgrade Notes#
Longer migration times can be expected. See this document for the estimated upgrade times with datasets of 10+ million posts. See this document for the estimated upgrade times with datasets of 70+ million posts. The field type of Data in model.ClusterMessage was changed to []byte from string. Therefore, a major thing to note is that a v6 server is incompatible to run along with a v5 server in a cluster. Customers upgrading from 5.x to 6.x cannot do a High Availability upgrade. While upgrading, it is required that no other v5 server runs when a v6 server is brought up. A v6 server will run significant database schema changes that can cause a large startup time depending on the dataset size. Zero downtime will not be possible, but depending on the efforts made during the migration process, it can be minimized to a large extent. It is recommended to start Mattermost directly and not through systemctl to avoid the server process getting killed during the migration. This can happen since the value of
TimeoutStartSec
in the provided systemctl service file is set to 1 hour. Customers using the Mattermost Kubernetes operator should be aware of the above migration information and choose the path that is most appropriate for them. If (1) is acceptable, then the normal upgrade process using the operator will suffice. For minimum downtime, follow (2) before using the operator to update Mattermost following the normal upgrade process.Low effort, long downtime - This is the usual process of starting a v6 server normally. This has 2 implications: during the migration process, various tables will be locked which will render those tables read-only during that period. Secondly, once the server finishes migration and starts the application, no other v5 server can run in the cluster.
Medium effort, medium downtime - This process will require SQL queries to be executed manually on the server. To avoid causing a table lock, a customer can choose to use the pt-online-schema-change tool for MySQL. For Postgres, the table locking is very minimal. The advantage is that since there are a lot of queries, the customer can take their own time to run individual queries during off-hours. All queries except #11 are safe to be executed this way. Then the usual method of (1) can be followed.
High effort, low downtime - This process requires everything of (2), plus it tries to minimize the impact of query #11. We can do this by following step 2, and then starting v6 along with a running v5 server, and then monitor the application logs. As soon as the v6 application starts up, we need to bring down a v5 node. This minimizes the downtime to only a few seconds.
While trying to upgrade to a Mattermost version >= 6.0.x, you might encounter the following error:
Failed to alter column type. It is likely you have invalid JSON values in the column. Please fix the values manually and run the migration again.
This means that the particular column has some invalid JSON values which need to be fixed manually. A common fix that is known to work is to wipe out all \u0000 characters. Please follow these steps:Check the affected values by:
SELECT COUNT(*) FROM <table> WHERE <column> LIKE '%\u0000%';
If you get a count more than 0, check those values manually, and confirm they are okay to be removed.
Remove them by
UPDATE <table> SET <column> = regexp_replace(<column>, '\\u0000', '', 'g') where <column> like '%\u0000%';
Then try to start Mattermost again.
Focalboard plugin has been renamed to Mattermost Boards, and v0.9.1 (released with Mattermost v6.0) is now enabled by default.
The advanced logging configuration schema changed. This is a breaking change relative to 5.x. See updated documentation.
Some breaking changes to plugins are included:
Support for left-hand side-specific bot icons was dropped.
Removed a deprecated “Backend” field from the plugin manifest.
Converted the “Executables” field in the plugin manifest to a map.
Collapsed Reply Threads, available in beta, are known to have a negative impact on server performance. If you cannot easily scale up and tune your database, or if you are running the Mattermost application server and database server on the same machine, we recommended disabling
ThreadAutoFollow
andCollapsedThreads
until Collapsed Reply Threads is promoted to general availability in Q2 2022. Learn more about these performance considerations here.
Important
If you upgrade from a release earlier than v5.39, please read the other Important Upgrade Notes.
Highlights#
Multi-Product Platform#
Mattermost now ships as one platform with three products - Channels, Playbooks, and Boards.
Playbooks and Boards are visible when plugins are enabled system-wide.
Global Product Launcher#
Added a global header for product navigation for Channels, Playbooks, and Boards. This is disabled on the mobile web view and mobile apps.
Branding Changes#
Added a new default brand theme named “Denim”.
The existing theme names and colors, including “Mattermost”, “Organization”, “Mattermost Dark”, and “Windows Dark” have been updated to the new “Denim”, “Sapphire”, “Quartz”, “Indigo”, and “Onyx” theme names and colors, respectively. Anyone using the existing themes will see slightly modified theme colors after their server or workspace is upgraded. The theme variables for the existing “Mattermost”, “Organization”, “Mattermost Dark”, and “Windows Dark” themes will still be accessible in our documentation, so a custom theme can be created with these theme variables if desired. Custom themes are unaffected by this change.
Added a new light theme named “Quartz” to the default available list of themes.
Updated email templates to the new branding.
Packaging Changes#
Updated in-product strings referencing E10 & E20 to new packaging.
Features moved from legacy E10 to all plans, including Team Edition:
System default permissions, e.g. permission to create and archive channels system-wide.
Specifically, “System Scheme” only in System Console > User Management > Permissions.
Existing permissions/policies in TE/E0 for “Enable Team Creation” and “Allow Team Administrators to edit others’ posts” are properly handled.
Team and Channel management pages (but without channel moderation, e.g. read-only channels).
Features moved from legacy E20 to Professional plan:
SSO with OpenID Connect, SAML, Google and Entra ID
O365 integrations including MS Teams Calling and MS Calendar
Jira multi-server support
Advanced team permissions
Channel moderation
E20, Professional, and Enterprise license SKUs are now supported for installing Enterprise plugins.
Beta features Promoted to General Availability#
Archived channels
Compliance exports
Custom terms of service
Guest accounts
System roles
Plugins
Permalink Previews#
Added support for permalink previews for posts in Mattermost. Previews are generated to minimize context switching when sharing message links in Channels.
Tutorial Updates#
Added a tip to the Getting Started page for downloading Desktop Apps.
Updated tutorial icons and changed text content in tutorial tips.
Updated the default treatment for the
Add channel
button to the current color and by team name.Added a tutorial tip for new settings and status buttons.

Increased the limit of uploaded file attachments per post from 5 to 10.
Added desktop notifications for followed Threads.
Hungarian and English-Australian are now official languages.
Added a Start Trial call-to action to the Main Menu.

Added a “rest field” to the App command parser.
Added support for React components in channel header tooltips registered by plugins.
Exported
ChannelInviteModal
andChannelMembersModal
components for plugins.
Administration#
Added
playbooks
andboards
to restricted team URLs list. Conflict exists if users hit the URL to the team directly without the trailing channel, permalink or threads information (ie server/team) and they have a team name “playbooks” or “boards”. User would expect to be taken to their messaging team.Added the ability for Team Edition to edit role permissions.
Removed a hard-coded override of
TeamSettings.MaxNotificationsPerChannel
on unlicensed servers (e.g. Team Edition).Migrated the extraction command to mmctl.
Removed the convert channel endpoint to use
/channels/{channel_id}/privacy
instead.Removed deprecated
Posts.ParentId
in favor of the semantically equivalentPosts.RootId

Known Issues#
Collapsed Reply Threads is currently in beta. Before enabling the feature, please ensure you are well versed in the known issues, particularly relating to database resource requirements and server performance implications. If you cannot easily scale up your database size, or are running the Mattermost application server and database server on the same machine, we recommended waiting to enable Collapsed Reply Threads until it is promoted to general availability in Q2 2022. Learn more about these performance considerations here.
Experimental timezones and custom statuses can cause an increase in CPU usage and database connections for servers with an E20 license. A current workaround is to disable custom statuses or to disable experimental timezones.
Adding an at-mention at the start of a post draft and pressing the leftwards or rightwards arrow can clear the post draft and the undo history MM-33823.
Pinned posts are no longer highlighted MM-34870.
Google login fails on the Classic mobile apps.
Status may sometimes get stuck as Away or Offline in High Availability mode with IP Hash turned off.
Searching stop words in quotation marks with Elasticsearch enabled returns more than just the searched terms.
The team sidebar on the desktop app does not update when channels have been read on mobile.
Slack import through the CLI fails if email notifications are enabled.
Push notifications don’t always clear on iOS when running Mattermost in High Availability mode.

Original 5.38.0 release
Mattermost v5.38.0 contains low to medium 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.
Deprecations#
The “config watcher” (the mechanism that automatically reloads the
config.json
file) has been removed in favor of themmctl config reload
command, which must be run to apply configuration changes after they are made on disk. This change improves configuration performance and robustness.
Important Upgrade Notes#
v5.38 adds fixes for some of the incorrect mention counts and unreads around threads and channels since the introduction of Collapsed Reply Threads (Beta). This fix is done through a SQL migration, and it may take several minutes to complete for large databases. The
fixCRTChannelMembershipCounts
fix takes 1 minute and 20 seconds for a database containing approximately 4 million channel memberships and about 130,000 channels. ThefixCRTThreadCountsAndUnreads
fix takes about 3 minutes and 30 seconds for a database containing 56367 threads, 124587 thread memberships, and 220801 channel memberships. These are on MySQL v5.6.51.Focalboard v0.8.2 (released with Mattermost v5.38.0) requires Mattermost v5.37+ due to the new database connection system.
Important
If you upgrade from a release earlier than v5.37, please read the other Important Upgrade Notes.

Please note there is a known issue where deleted posts get displayed in channels without new activity after the retention job is run. This issue is tracked with this ticket.
Enhanced User Onboarding Experience#
To help new users get started with Mattermost, new Getting Started steps have been added to the onboarding experience. These steps help users to complete their profile, name their teams, configure desktop notifications, and invite others to join their team. Additionally, once the onboarding is complete, users are provided with helpful tips to get started with channels, plugins, and more.

Important Upgrade Notes#
Collapsed Reply Threads are available as beta in Mattermost Server v5.37 and later. It’s expected that you may experience bugs as we stabilize the feature. In particular, please be aware of the known issues documented here.
v5.37 adds support for emoji standard v13.0. If you have added a custom emoji in the past that uses one of the new system names, then that custom emoji is going to get overwritten by the system emoji. The workaround is to change the custom emoji name.
Parts of Incident Collaboration are now available to all Mattermost editions. As part of this update, Incident Collaboration will require a minimum server version of v5.37. To learn more about what is available in each edition, visit our pricing page.
Support for Mattermost Server v5.31 Extended Support Release will come to the end of its life cycle on October 15, 2021. Upgrading to Mattermost Server v5.37 or later is required.
Collapsed Reply Threads, available in beta, are known to have a negative impact on server performance. If you cannot easily scale up and tune your database, or if you are running the Mattermost application server and database server on the same machine, we recommended disabling
ThreadAutoFollow
andCollapsedThreads
until Collapsed Reply Threads is promoted to general availability in Q2 2022. Learn more about these performance considerations here.

v5.36.0, released 2021-06-16
Original 5.36.0 release
Mattermost v5.36.0 contains a high level security fix. 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#
Gossip clustering mode is now in General Availability and is no longer available as an option. All cluster traffic will always use the gossip protocol. The config setting
UseExperimentalGossip
has no effect and has only been kept for compatibility purposes. The setting to use gossip has been removed from the System Console. Note: For High Availability upgrades, all nodes in the cluster must use a single protocol. If an existing system is not currently using gossip, one node in a cluster can’t be upgraded while other nodes in the cluster use an older version. Customers must either use gossip for their High Availability upgrade, or customers must shut down all nodes, perform the upgrade, and then bring all nodes back up.
Important
If you upgrade from a release earlier than v5.35, please read the other Important Upgrade Notes.
Highlights#
Focalboard (Beta)#
Focalboard is now integrated with Mattermost as a beta feature in v5.36. To enable Focalboard, open the Marketplace from the sidebar menu, install the Focalboard plugin, then click on Configure, enable it, and save. Update your NGINX or Apache web proxy config following these steps.

Upcoming Deprecations in Mattermost v6.0#
The following deprecations are planned for the Mattermost v6.0 release, which is scheduled for 2021/10/15. This list is subject to change prior to the release.
Legacy Command Line Tools. All commands have been fully replaced by mmctl and new commands have been added over the last few months, making this tool a full and robust replacement.
Slack Import via the web app. The Slack import tool accessible via the Team Setting menu is being replaced by the mmetl tool that is much more comprehensive for the types of data it can assist in uploading.
MySQL versions below 5.7.7. Minimum support will now be for 5.7.12. This version introduced a native JSON data type that lets us improve performance and scalability of several database fields (most notably Users and Posts props). Additionally, version 5.6 (our current minimum version) reached EOL in February 2021.
Elasticsearch 5 and 6 - versions 5.x reached EOL in March of 2019, and versions 6.x reached EOL in November 2020. Our minimal supported version with Mattermost v6.0 will be Elasticsearch version 7.0.
Windows 7 reached EOL in January 2020. We will no longer provide support for the Desktop App issues on Windows 7.
DisableLegacyMFA configuration setting.
ExperimentalTimezone configuration setting.
All legacy channel sidebar experimental configuration settings. We encourage customers using these settings to upgrade to v5.32 or later to access custom, collapsible channel categories among many other channel organization features. The settings being deprecated include:
All configuration settings previously marked as “Deprecated”.
Changes to
mattermost-server/model
for naming consistency.

should be used instead. MM-35767
v5.35.0, released 2021-05-16
Original 5.35.0 release
Mattermost v5.35.0 contains low and medium 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#
Due to the introduction of backend database architecture required for upcoming new features, including Shared Channels and Collapsed Reply Threads, the performance of the migration process for the v5.35 release (May 16, 2021) has been noticeably affected. Depending on the size, type, and version of the database, longer than usual upgrade times should be expected. This can vary from a couple of minutes (average case) to hours (worst case, MySQL 5.x only). A moderate to significant spike in database CPU usage should also be expected during this process. More details on the performance impact of the migration and possible mitigation strategies are provided here.
v5.35.0 introduces a new feature to search for files. Search results for files shared in the past may be incomplete until a content extraction command is executed to extract and index the content of files already in the database. Instances running Elasticsearch or Bleve search backends will also need to execute a Bulk Indexing after the content extraction is complete. Please see more details in this blog post.
The existing password generation logic used during the bulk user import process was comparatively weak. Hence it’s advised for admins to immediately reset the passwords for all the users who were generated during the bulk import process and whose password has not been changed even once.
In the v5.38 release (August 16, 2021), we will deprecate “config watcher” (the mechanism that automatically reloads the
config.json file
), in favor of an mmctl command that will need to be run to apply configuration changes after they are made. This change will improve configuration performance and robustness.
Important
If you upgrade from a release earlier than v5.34, please read the other Important Upgrade Notes.
Highlights#
Apps Framework (Developer Preview)#
Apps Framework is a new way to integrate with external tools, and allows developers to create interactive apps in Mattermost, using any development language they’re comfortable with. The new apps work seamlessly across mobile and desktop clients. This is a developer preview and is not intended for production instances of Mattermost yet. This feature is available for self-managed customers with v5.35 when the Apps Framework Plugin is loaded on an instance.
Search for files and document contents#
Searching in Mattermost now finds both relevant messages and files in your team’s conversation history. Search will return results for attachments that match the file name or contain matching text content within supported document types. Learn more.
Granular Access to System Console Pages (Enterprise E20 Edition)#
Migrated Experimental, About, Reporting, Environment, Site Configuration, Authentication, Integrations, and Compliance sections to their respective sub-section permissions.
Enterprise Trial Enhancements (Enterprise E20 Edition)#
Added banners to alert System Admins when an Enterprise Edition E20 trial has started, when there are three days left of the trial, and when the trial is on the last day.
Incident Collaboration (Enterprise Edition E20)#
Updated prepackaged Incident Collaboration plugin with to include ad hoc tasks, stakeholder overview, and more.
Improvements#
User Interface (UI)#
Added support to collapse in-line images over 100px in height.
Implemented maximum length validation on the status modal for custom statuses.
Synchronized collapsed channel sidebar categories on the server to keep category collapse states in-sync across devices.
Empty state is no longer off-centered in the Channel Switcher.
Ephemeral message created from call response
markdown
field is now posted by bot.Added various enhancements to custom status to allow users to switch to recent statuses with less clicks.
Users can now see online status on user profile images in the channel switcher.
Added a string field to restricted domains configuration 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.Added an unread badge to the Main Menu icon and the Plugin Marketplace menu that displays until a System Admin visits the Plugin Marketplace for the first time.
Profile images are now visible on Direct Messages in the channel sidebar.
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#
Paused Admin Advisor notifications from triggering.
Added a command line document extraction command that allows indexing documents by content.
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
andmattermost_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 underSqlSettings
. This is an array of maps which contain three keys:DataSource
,QueryAbsoluteLag
, andQueryTimeLag
. 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()
whereserver_id=<>
andQueryTimeLag
can be:select server_id, visibility_lag_in_msec aurora_global_db_instance_status()
whereserver_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
wheremember_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 link previews on a number of websites, including Reddit.
Fixed an issue where SAML assigned Mattermost
UserID
as username if the value was invalid and did not log this.Fixed an issue where hover effects for category sorting and Direct Messages category limit submenus were too dark on a dark theme.
Fixed an issue where users were unable to drag the vertical scroll bar on a PDF preview.
Fixed an issue with animations on long posts when highlighted as a permalink.
Fixed an issue where the user’s nickname was not shown on channel switch.
Fixed an issue where deactivated users were not marked as Deactivated in the channel switcher.
Fixed an issue where queries executed during the upgrade process would pre-emptively time out on the application side.
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.
Fixed an issue where the Show more background color on long posts was broken for permalinks.
Fixed an issue where redirecting with JS failed when Content Security Policy was enabled and restricted with
unsafe-inline
.

Improved typing performance on busy servers with lots of active users and with the new sidebar enabled. MM-30407

v5.33.0, released 2021-03-17
Original 5.33.0 release
Mattermost v5.33.0 contains low-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#
Deleting a reaction is now a soft delete in the
Reactions
table. A schema update is required and may take up to 15 seconds on first run with large data sets.WebSocket handshakes done with an HTTP version lower than 1.1 will result in a warning, and the server will transparently upgrade the version to 1.1 to comply with the WebSocket RFC. This is done to work around incorrect Nginx (and other proxy) configs that do not set the
proxy_http_version
directive to 1.1. This facility will be removed in a future Mattermost version. It is strongly recommended to fix the proxy configuration to correctly use the WebSocket protocol.
Important
If you upgrade from a release earlier than v5.32, please read the other Important Upgrade Notes.
Highlights#
OpenID Connect for OAuth 2.0 Authentication (E20 Edition)#
OpenID Connect enables authentication to Mattermost using any OAuth 2.0 provider that adheres to the OpenID Connect specification. This feature is available for Mobile Apps in the v1.40 release.
Support Packet Generation (E10 & E20 Editions)#
Mattermost provides the ability to download configuration details, logs, and other deployment information when requesting commercial support for Mattermost self-managed E10 or E20 Enterprise editions, or Mattermost Cloud editions.
Updated Incident Collaboration Plugin to 1.4.0 (E20 Edition)#
Added an Incident Timeline to support status updates and other key events shown chronologically in the right-hand sidebar. The timeline enables users to easily gather information for post-incident reports.
Custom Statuses#
Users now gain the flexibility to express their current status in any way they prefer. Set a custom status to add a descriptive status message and emoji that’s visible to everyone throughout the app.
Improvements#
User Interface (UI)#
Improved the Add Members to channel modal.
Added Formatting shortcut keys to the Shortcut modal.
Added localization to the date picker used when searching for posts around a given date.
The autocomplete popover is now positioned relative to the @, ~, or / trigger in the post draft.
Removed the 5-page limit on previewing PDFs.
Added
files
as a reserved team name.Searching for a channel by URL now returns the channel.
Users are now provided with feedback when creating a custom category name that exceeds the character limit.

mattermost_system_server_start_time
andmattermost_jobs_active
metrics for improved debugging with Grafana dashboards.Deleting a reaction is now a soft delete in the

Server crashes due to runtime panics are now captured as a log line.
Optimized Direct Message creation by fetching all users involved in a single database call.
During the user import process, a change in a user’s
NotifyProps

Fixed an issue where creation of a bot would fail due to replica lag.
The
DownloadComplianceReport
