Upgrading GitLab (FREE SELF)

Upgrading GitLab is a relatively straightforward process, but the complexity can increase based on the installation method you have used, how old your GitLab version is, if you're upgrading to a major version, and so on.

Make sure to read the whole page as it contains information related to every upgrade method.

NOTE: Upgrade GitLab to the latest available patch release, for example 13.8.8 rather than 13.8.0. This includes versions you must stop at on the upgrade path as there may be fixes for issues relating to the upgrade process.

The maintenance policy documentation has additional information about upgrading, including:

  • How to interpret GitLab product versioning.
  • Recommendations on the what release to run.
  • How we use patch and security patch releases.
  • When we backport code changes.

Upgrade based on installation method

Depending on the installation method and your GitLab version, there are multiple official ways to update GitLab:

Linux packages (Omnibus GitLab)

The package upgrade guide contains the steps needed to update a package installed by official GitLab repositories.

There are also instructions when you want to update to a specific version.

Installation from source

In the past we used separate documents for the upgrading instructions, but we have since switched to using a single document. The old upgrading guidelines can still be found in the Git repository:

Installation using Docker

GitLab provides official Docker images for both Community and Enterprise editions. They are based on the Omnibus package and instructions on how to update them are in a separate document.

Installation using Helm

GitLab can be deployed into a Kubernetes cluster using Helm. Instructions on how to update a cloud-native deployment are in a separate document.

Use the version mapping from the chart version to GitLab version to determine the upgrade path.

Plan your upgrade

See the guide to plan your GitLab upgrade.

Checking for background migrations before upgrading

Certain releases may require different migrations to be finished before you update to the newer version.

Batched migrations are a migration type available in GitLab 14.0 and later. Background migrations and batched migrations are not the same, so you should check that both are complete before updating.

Decrease the time required to complete these migrations by increasing the number of Sidekiq workers that can process jobs in the background_migration queue.

Background migrations

For Omnibus installations:

sudo gitlab-rails runner -e production 'puts Gitlab::BackgroundMigration.remaining'
sudo gitlab-rails runner -e production 'puts Gitlab::Database::BackgroundMigrationJob.pending.count'

For installations from source:

cd /home/git/gitlab
sudo -u git -H bundle exec rails runner -e production 'puts Gitlab::BackgroundMigration.remaining'
sudo -u git -H bundle exec rails runner -e production 'puts Gitlab::Database::BackgroundMigrationJob.pending.count'

Batched background migrations

GitLab 14.0 introduced batched background migrations.

Some installations may need to run GitLab 14.0 for at least a day to complete the database changes introduced by that upgrade.

Check the status of batched background migrations

To check the status of batched background migrations:

  1. On the top bar, select Menu > Admin.

  2. On the left sidebar, select Monitoring > Background Migrations.

    queued batched background migrations table

All migrations must have a Finished status before you upgrade GitLab.

The status of batched background migrations can also be queried directly in the database.

  1. Log into a psql prompt according to the directions for your instance's installation method (for example, sudo gitlab-psql for Omnibus installations).

  2. Run the following query in the psql session to see details on incomplete batched background migrations:

    select job_class_name, table_name, column_name, job_arguments from batched_background_migrations where status <> 3;

If the migrations are not finished and you try to update to a later version, GitLab prompts you with an error:

Expected batched background migration for the given configuration to be marked as 'finished', but it is 'active':

If you get this error, check the batched background migration options to complete the upgrade.

What do I do if my background migrations are stuck?

WARNING: The following operations can disrupt your GitLab performance. They run a number of Sidekiq jobs that perform various database or file updates.

Background migrations remain in the Sidekiq queue

Run the following check. If it returns non-zero and the count does not decrease over time, follow the rest of the steps in this section.

# For Omnibus installations:
sudo gitlab-rails runner -e production 'puts Gitlab::BackgroundMigration.remaining'

# For installations from source:
cd /home/git/gitlab
sudo -u git -H bundle exec rails runner -e production 'puts Gitlab::BackgroundMigration.remaining'

It is safe to re-execute the following commands, especially if you have 1000+ pending jobs which would likely overflow your runtime memory.

For Omnibus installations

# Start the rails console
sudo gitlab-rails c

# Execute the following in the rails console
scheduled_queue = Sidekiq::ScheduledSet.new
pending_job_classes = scheduled_queue.select { |job| job["class"] == "BackgroundMigrationWorker" }.map { |job| job["args"].first }.uniq
pending_job_classes.each { |job_class| Gitlab::BackgroundMigration.steal(job_class) }

For installations from source

# Start the rails console
sudo -u git -H bundle exec rails RAILS_ENV=production

# Execute the following in the rails console
scheduled_queue = Sidekiq::ScheduledSet.new
pending_job_classes = scheduled_queue.select { |job| job["class"] == "BackgroundMigrationWorker" }.map { |job| job["args"].first }.uniq
pending_job_classes.each { |job_class| Gitlab::BackgroundMigration.steal(job_class) }

Background migrations stuck in 'pending' state

GitLab 13.6 introduced an issue where a background migration named BackfillJiraTrackerDeploymentType2 can be permanently stuck in a pending state across upgrades. To clean up this stuck migration, see the 13.6.0 version-specific instructions.

GitLab 14.4 introduced an issue where a background migration named PopulateTopicsTotalProjectsCountCache can be permanently stuck in a pending state across upgrades when the instance lacks records that match the migration's target. To clean up this stuck migration, see the 14.4.0 version-specific instructions.

GitLab 14.8 introduced an issue where a background migration named PopulateTopicsNonPrivateProjectsCount can be permanently stuck in a pending state across upgrades. To clean up this stuck migration, see the 14.8.0 version-specific instructions.

GitLab 14.9 introduced an issue where a background migration named ResetDuplicateCiRunnersTokenValuesOnProjects can be permanently stuck in a pending state across upgrades when the instance lacks records that match the migration's target. To clean up this stuck migration, see the 14.9.0 version-specific instructions.

For other background migrations stuck in pending, run the following check. If it returns non-zero and the count does not decrease over time, follow the rest of the steps in this section.

# For Omnibus installations:
sudo gitlab-rails runner -e production 'puts Gitlab::Database::BackgroundMigrationJob.pending.count'

# For installations from source:
cd /home/git/gitlab
sudo -u git -H bundle exec rails runner -e production 'puts Gitlab::Database::BackgroundMigrationJob.pending.count'

It is safe to re-attempt these migrations to clear them out from a pending status:

For Omnibus installations

# Start the rails console
sudo gitlab-rails c

# Execute the following in the rails console
Gitlab::Database::BackgroundMigrationJob.pending.find_each do |job|
  puts "Running pending job '#{job.class_name}' with arguments #{job.arguments}"
  result = Gitlab::BackgroundMigration.perform(job.class_name, job.arguments)
  puts "Result: #{result}"
end

For installations from source

# Start the rails console
sudo -u git -H bundle exec rails RAILS_ENV=production

# Execute the following in the rails console
Gitlab::Database::BackgroundMigrationJob.pending.find_each do |job|
  puts "Running pending job '#{job.class_name}' with arguments #{job.arguments}"
  result = Gitlab::BackgroundMigration.perform(job.class_name, job.arguments)
  puts "Result: #{result}"
end

Batched migrations (GitLab 14.0 and later)

See troubleshooting batched background migrations.

Dealing with running CI/CD pipelines and jobs

If you upgrade your GitLab instance while the GitLab Runner is processing jobs, the trace updates fail. When GitLab is back online, the trace updates should self-heal. However, depending on the error, the GitLab Runner either retries or eventually terminates job handling.

As for the artifacts, the GitLab Runner attempts to upload them three times, after which the job eventually fails.

To address the above two scenario's, it is advised to do the following prior to upgrading:

  1. Plan your maintenance.
  2. Pause your runners.
  3. Wait until all jobs are finished.
  4. Upgrade GitLab.
  5. Update GitLab Runner to the same version as your GitLab version. Both versions should be the same.

Checking for pending Advanced Search migrations (PREMIUM SELF)

This section is only applicable if you have enabled the Elasticsearch integration (PREMIUM SELF).

Major releases require all Advanced Search migrations to be finished from the most recent minor release in your current version before the major version upgrade. You can find pending migrations by running the following command:

For Omnibus installations

sudo gitlab-rake gitlab:elastic:list_pending_migrations

For installations from source

cd /home/git/gitlab
sudo -u git -H bundle exec rake gitlab:elastic:list_pending_migrations

What do I do if my Advanced Search migrations are stuck?

See how to retry a halted migration.

Upgrading without downtime

Read how to upgrade without downtime.

Upgrading to a new major version

Upgrading the major version requires more attention. Backward-incompatible changes and migrations are reserved for major versions. Follow the directions carefully as we cannot guarantee that upgrading between major versions is seamless.

A major upgrade requires the following steps:

  1. Start by identifying a supported upgrade path. This is essential for a successful major version upgrade.
  2. Upgrade to the latest minor version of the preceding major version.
  3. Upgrade to the "dot zero" release of the next major version (X.0.Z).
  4. Optional. Follow the upgrade path, and proceed with upgrading to newer releases of that major version.

It's also important to ensure that any background migrations have been fully completed before upgrading to a new major version.

If you have enabled the Elasticsearch integration (PREMIUM SELF), then ensure all Advanced Search migrations are completed in the last minor version within your current version before proceeding with the major version upgrade.

If your GitLab instance has any runners associated with it, it is very important to upgrade GitLab Runner to match the GitLab minor version that was upgraded to. This is to ensure compatibility with GitLab versions.

Upgrade paths

Upgrading across multiple GitLab versions in one go is only possible by accepting downtime. The following examples assume downtime is acceptable while upgrading. If you don't want any downtime, read how to upgrade with zero downtime.

Find where your version sits in the upgrade path below, and upgrade GitLab accordingly, while also consulting the version-specific upgrade instructions:

8.11.Z -> 8.12.0 -> 8.17.7 -> 9.5.10 -> 10.8.7 -> 11.11.8 -> 12.0.12 -> 12.1.17 -> 12.10.14 -> 13.0.14 -> 13.1.11 -> 13.8.8 -> 13.12.15 -> 14.0.12 -> latest 14.Y.Z

The following table, while not exhaustive, shows some examples of the supported upgrade paths. Additional steps between the mentioned versions are possible. We list the minimally necessary steps only.

Target version Your version Supported upgrade path Note
14.6.2 13.10.2 13.10.2 -> 13.12.15 -> 14.0.12 -> 14.6.2 Two intermediate versions are required: 13.12 and 14.0, then 14.6.2.
14.1.8 13.9.2 13.9.2 -> 13.12.15 -> 14.0.12 -> 14.1.8 Two intermediate versions are required: 13.12 and 14.0, then 14.1.8.
13.12.15 12.9.2 12.9.2 -> 12.10.14 -> 13.0.14 -> 13.1.11 -> 13.8.8 -> 13.12.15 Four intermediate versions are required: 12.10, 13.0, 13.1 and 13.8.8, then 13.12.15.
13.2.10 11.5.0 11.5.0 -> 11.11.8 -> 12.0.12 -> 12.1.17 -> 12.10.14 -> 13.0.14 -> 13.1.11 -> 13.2.10 Six intermediate versions are required: 11.11, 12.0, 12.1, 12.10, 13.0 and 13.1, then 13.2.10.
12.10.14 11.3.4 11.3.4 -> 11.11.8 -> 12.0.12 -> 12.1.17 -> 12.10.14 Three intermediate versions are required: 11.11, 12.0 and 12.1, then 12.10.14.
12.9.5 10.4.5 10.4.5 -> 10.8.7 -> 11.11.8 -> 12.0.12 -> 12.1.17 -> 12.9.5 Four intermediate versions are required: 10.8, 11.11, 12.0 and 12.1, then 12.9.5.
12.2.5 9.2.6 9.2.6 -> 9.5.10 -> 10.8.7 -> 11.11.8 -> 12.0.12 -> 12.1.17 -> 12.2.5 Five intermediate versions are required: 9.5, 10.8, 11.11, 12.0, and 12.1, then 12.2.5.
11.3.4 8.13.4 8.13.4 -> 8.17.7 -> 9.5.10 -> 10.8.7 -> 11.3.4 8.17.7 is the last version in version 8, 9.5.10 is the last version in version 9, 10.8.7 is the last version in version 10.

Upgrading between editions

GitLab comes in two flavors: Community Edition which is MIT licensed, and Enterprise Edition which builds on top of the Community Edition and includes extra features mainly aimed at organizations with more than 100 users.

Below you can find some guides to help you change GitLab editions.

Community to Enterprise Edition

NOTE: The following guides are for subscribers of the Enterprise Edition only.

If you wish to upgrade your GitLab installation from Community to Enterprise Edition, follow the guides below based on the installation method:

  • Source CE to EE update guides - The steps are very similar to a version upgrade: stop the server, get the code, update configuration files for the new functionality, install libraries and do migrations, update the init script, start the application and check its status.
  • Omnibus CE to EE - Follow this guide to update your Omnibus GitLab Community Edition to the Enterprise Edition.
  • Docker CE to EE - Follow this guide to update your GitLab Community Edition container to an Enterprise Edition container.

Enterprise to Community Edition

If you need to downgrade your Enterprise Edition installation back to Community Edition, you can follow this guide to make the process as smooth as possible.

Version-specific upgrading instructions

Each month, major, minor or patch releases of GitLab are published along with a release post. You should read the release posts for all versions you're passing over. At the end of major and minor release posts, there are three sections to look for specifically:

  • Deprecations
  • Removals
  • Important notes on upgrading

These include:

  • Steps you need to perform as part of an upgrade. For example 8.12 required the Elasticsearch index to be recreated. Any older version of GitLab upgrading to 8.12 or higher would require this.
  • Changes to the versions of software we support such as ceasing support for IE11 in GitLab 13.

Apart from the instructions in this section, you should also check the installation-specific upgrade instructions, based on how you installed GitLab:

NOTE: Specific information that follow related to Ruby and Git versions do not apply to Omnibus installations and Helm Chart deployments. They come with appropriate Ruby and Git versions and are not using system binaries for Ruby and Git. There is no need to install Ruby or Git when utilizing these two approaches.

14.10.0

  • The upgrade to GitLab 14.10 executes a concurrent index drop of unneeded entries from the ci_job_artifacts database table. This could potentially run for multiple minutes, especially if the table has a lot of traffic and the migration is unable to acquire a lock. It is advised to let this process finish as restarting may result in data loss.

14.9.0

  • Database changes made by the upgrade to GitLab 14.9 can take hours or days to complete on larger GitLab instances. These batched background migrations update whole database tables to ensure corresponding records in namespaces table for each record in projects table.

    After you update to 14.9.0 or a later 14.9 patch version, batched background migrations need to finish before you update to a later version.

    If the migrations are not finished and you try to update to a later version, you'll see an error like:

    Expected batched background migration for the given configuration to be marked as 'finished', but it is 'active':

  • GitLab 14.9.0 includes a background migration ResetDuplicateCiRunnersTokenValuesOnProjects that may remain stuck permanently in a pending state.

    To clean up this stuck job, run the following in the GitLab Rails Console:

    Gitlab::Database::BackgroundMigrationJob.pending.where(class_name: "ResetDuplicateCiRunnersTokenValuesOnProjects").find_each do |job|
  puts Gitlab::Database::BackgroundMigrationJob.mark_all_as_succeeded("ResetDuplicateCiRunnersTokenValuesOnProjects", job.arguments)
end

14.8.0

  • If upgrading from a version earlier than 14.6.5, 14.7.4, or 14.8.2, please review the Critical Security Release: 14.8.2, 14.7.4, and 14.6.5 blog post. Updating to 14.8.2 or later will reset runner registration tokens for your groups and projects.

  • The agent server for Kubernetes is enabled by default on Omnibus installations. If you run GitLab at scale, such as the reference architectures, you must disable the agent on the following server types, if the agent is not required.

    • Praefect
    • Gitaly
    • Sidekiq
    • Redis (if configured using redis['enable'] = true and not via roles)
    • Container registry
    • Any other server types based on roles(['application_role']), such as the GitLab Rails nodes

    The reference architectures have been updated with this configuration change and a specific role for standalone Redis servers.

    Steps to disable the agent:

    1. Add gitlab_kas['enable'] = false to gitlab.rb.
    2. If the server is already upgraded to 14.8, run gitlab-ctl reconfigure.

  • GitLab 14.8.0 includes a background migration PopulateTopicsNonPrivateProjectsCount that may remain stuck permanently in a pending state.

    To clean up this stuck job, run the following in the GitLab Rails Console:

        Gitlab::Database::BackgroundMigrationJob.pending.where(class_name: "PopulateTopicsNonPrivateProjectsCount").find_each do |job|
      puts Gitlab::Database::BackgroundMigrationJob.mark_all_as_succeeded("PopulateTopicsNonPrivateProjectsCountq", job.arguments)
    end

  • If upgrading from a version earlier than 14.3.0, to avoid an issue with job retries, first upgrade to GitLab 14.7.x and make sure all batched migrations have finished.

  • If upgrading from version 14.3.0 or later, you might notice a failed batched migration named BackfillNamespaceIdForNamespaceRoute. You can ignore this. Retry it after you upgrade to version 14.9.x.

14.7.0

  • See LFS objects import and mirror issue in GitLab 14.6.0 to 14.7.2.

  • If upgrading from a version earlier than 14.6.5, 14.7.4, or 14.8.2, please review the Critical Security Release: 14.8.2, 14.7.4, and 14.6.5 blog post. Updating to 14.7.4 or later will reset runner registration tokens for your groups and projects.

  • GitLab 14.7 introduced a change where Gitaly expects persistent files in the /tmp directory. When using the noatime mount option on /tmp in a node running Gitaly, most Linux distributions run into an issue with Git server hooks getting deleted. These conditions are present in the default Amazon Linux configuration.

    If your Linux distribution manages files in /tmp with the tmpfiles.d service, you can override the behavior of tmpfiles.d for the Gitaly files and avoid this issue:

    sudo printf "x /tmp/gitaly-%s-*\n" hooks git-exec-path >/etc/tmpfiles.d/gitaly-workaround.conf

14.6.0

14.5.0

  • When make is run, Gitaly builds are now created in _build/bin and no longer in the root directory of the source directory. If you are using a source install, update paths to these binaries in your systemd unit files or init scripts by following the documentation.

  • Connections between Workhorse and Gitaly use the Gitaly backchannel protocol by default. If you deployed a gRPC proxy between Workhorse and Gitaly, Workhorse can no longer connect. As a workaround, disable the temporary workhorse_use_sidechannel feature flag. If you need a proxy between Workhorse and Gitaly, use a TCP proxy. If you have feedback about this change, please go to this issue.

  • In 14.1 we introduced a background migration that changes how we store merge request diff commits in order to significantly reduce the amount of storage needed. In 14.5 we introduce a set of migrations that wrap up this process by making sure that all remaining jobs over the merge_request_diff_commits table are completed. These jobs will have already been processed in most cases so that no extra time is necessary during an upgrade to 14.5. However, if there are remaining jobs or you haven't already upgraded to 14.1, the deployment may take multiple hours to complete.

    All merge request diff commits will automatically incorporate these changes, and there are no additional requirements to perform the upgrade. Existing data in the merge_request_diff_commits table remains unpacked until you run VACUUM FULL merge_request_diff_commits. But note that the VACUUM FULL operation locks and rewrites the entire merge_request_diff_commits table, so the operation takes some time to complete and it blocks access to this table until the end of the process. We advise you to only run this command while GitLab is not actively used or it is taken offline for the duration of the process. The time it takes to complete depends on the size of the table, which can be obtained by using select pg_size_pretty(pg_total_relation_size('merge_request_diff_commits'));.

    For more information, refer to this issue.

14.4.4

  • For zero-downtime upgrades on a GitLab cluster with separate Web and API nodes, you need to enable the paginated_tree_graphql_query feature flag before upgrading GitLab Web nodes to 14.4. This is because we enabled `paginated_tree_graphql_query by default in 14.4, so if GitLab UI is on 14.4 and its API is on 14.3, the frontend will have this feature enabled but the backend will have it disabled. This will result in the following error:

    bundle.esm.js:63 Uncaught (in promise) Error: GraphQL error: Field 'paginatedTree' doesn't exist on type 'Repository'

14.4.0

14.3.0

14.2.0

14.1.0

  • Instances running 14.0.0 - 14.0.4 should not upgrade directly to GitLab 14.2 or later but can upgrade to 14.1.Z.

    It is not required for instances already running 14.0.5 (or higher) to stop at 14.1.Z. 14.1 is included on the upgrade path for the broadest compatibility with self-managed installations, and ensure 14.0.0-14.0.4 installations do not encounter issues with batched background migrations.

  • Upgrading to GitLab 14.5 (or later) may take a lot longer if you do not upgrade to at least 14.1 first. The 14.1 merge request diff commits database migration can take hours to run, but runs in the background while GitLab is in use. GitLab instances upgraded directly from 14.0 to 14.5 or later must run the migration in the foreground and therefore take a lot longer to complete.

  • See Maintenance mode issue in GitLab 13.9 to 14.4.

14.0.0

Upgrading to later 14.Y releases

13.12.0

See Maintenance mode issue in GitLab 13.9 to 14.4.

13.11.0

13.10.0

See Maintenance mode issue in GitLab 13.9 to 14.4.

13.9.0

  • We've detected an issue with a column rename that prevents upgrades to GitLab 13.9.0, 13.9.1, 13.9.2, and 13.9.3 when following the zero-downtime steps. It is necessary to perform the following additional steps for the zero-downtime upgrade:

    1. Before running the final sudo gitlab-rake db:migrate command on the deploy node, execute the following queries using the PostgreSQL console (or sudo gitlab-psql) to drop the problematic triggers:

      drop trigger trigger_e40a6f1858e6 on application_settings;
drop trigger trigger_0d588df444c8 on application_settings;
drop trigger trigger_1572cbc9a15f on application_settings;
drop trigger trigger_22a39c5c25f3 on application_settings;

    2. Run the final migrations:

      sudo gitlab-rake db:migrate

    If you have already run the final sudo gitlab-rake db:migrate command on the deploy node and have encountered the column rename issue, you see the following error:

    -- remove_column(:application_settings, :asset_proxy_whitelist)
rake aborted!
StandardError: An error has occurred, all later migrations canceled:
PG::DependentObjectsStillExist: ERROR: cannot drop column asset_proxy_whitelist of table application_settings because other objects depend on it
DETAIL: trigger trigger_0d588df444c8 on table application_settings depends on column asset_proxy_whitelist of table application_settings

    To work around this bug, follow the previous steps to complete the update. More details are available in this issue.

  • See Maintenance mode issue in GitLab 13.9 to 14.4.

  • For GitLab Enterprise Edition customers, we noticed an issue when subscription expiration is upcoming, and you create new subgroups and projects. If you fall under that category and get 500 errors, you can work around this issue:

    1. SSH into you GitLab server, and open a Rails console:

      sudo gitlab-rails console

    2. Disable the following features:

      Feature.disable(:subscribable_subscription_banner)
Feature.disable(:subscribable_license_banner)

    3. Restart Puma or Unicorn:

      #For installations using Puma
sudo gitlab-ctl restart puma

#For installations using Unicorn
sudo gitlab-ctl restart unicorn

13.8.8

GitLab 13.8 includes a background migration to address an issue with duplicate service records. If duplicate services are present, this background migration must complete before a unique index is applied to the services table, which was introduced in GitLab 13.9. Upgrades from GitLab 13.8 and earlier to later versions must include an intermediate upgrade to GitLab 13.8.8 and must wait until the background migrations complete before proceeding.

If duplicate services are still present, an upgrade to 13.9.x or later results in a failed upgrade with the following error:

PG::UniqueViolation: ERROR:  could not create unique index "index_services_on_project_id_and_type_unique"
DETAIL:  Key (project_id, type)=(NNN, ServiceName) is duplicated.

13.6.0

Ruby 2.7.2 is required. GitLab does not start with Ruby 2.6.6 or older versions.

The required Git version is Git v2.29 or higher.

GitLab 13.6 includes a background migration BackfillJiraTrackerDeploymentType2 that may remain stuck permanently in a pending state despite completion of work due to a bug.

To clean up this stuck job, run the following in the GitLab Rails Console:

Gitlab::Database::BackgroundMigrationJob.pending.where(class_name: "BackfillJiraTrackerDeploymentType2").find_each do |job|
  puts Gitlab::Database::BackgroundMigrationJob.mark_all_as_succeeded("BackfillJiraTrackerDeploymentType2", job.arguments)
end

13.4.0

GitLab 13.4.0 includes a background migration to move all remaining repositories in legacy storage to hashed storage. There are known issues with this migration which are fixed in GitLab 13.5.4 and later. If possible, skip 13.4.0 and upgrade to 13.5.4 or higher instead. Note that the migration can take quite a while to run, depending on how many repositories must be moved. Be sure to check that all background migrations have completed before upgrading further.

13.3.0

The recommended Git version is Git v2.28. The minimum required version of Git v2.24 remains the same.

13.2.0

GitLab installations that have multiple web nodes must be upgraded to 13.1 before upgrading to 13.2 (and later) due to a breaking change in Rails that can result in authorization issues.

GitLab 13.2.0 remediates an email verification bypass. After upgrading, if some of your users are unexpectedly encountering 404 or 422 errors when signing in, or "blocked" messages when using the command line, their accounts may have been un-confirmed. In that case, please ask them to check their email for a re-confirmation link. For more information, see our discussion of Email confirmation issues.

GitLab 13.2.0 relies on the btree_gist extension for PostgreSQL. For installations with an externally managed PostgreSQL setup, please make sure to install the extension manually before upgrading GitLab if the database user for GitLab is not a superuser. This is not necessary for installations using a GitLab managed PostgreSQL database.

13.1.0

In 13.1.0, you must upgrade to either:

  • At least Git v2.24 (previously, the minimum required version was Git v2.22).
  • The recommended Git v2.26.

Failure to do so results in internal errors in the Gitaly service in some RPCs due to the use of the new --end-of-options Git flag.

Additionally, in GitLab 13.1.0, the version of Rails was upgraded from 6.0.3 to 6.0.3.1. The Rails upgrade included a change to CSRF token generation which is not backwards-compatible - GitLab servers with the new Rails version generate CSRF tokens that are not recognizable by GitLab servers with the older Rails version - which could cause non-GET requests to fail for multi-node GitLab installations.

So, if you are using multiple Rails servers and specifically upgrading from 13.0, all servers must first be upgraded to 13.1.Z before upgrading to 13.2.0 or later:

  1. Ensure all GitLab web nodes are running GitLab 13.1.Z.

  2. Enable the global_csrf_token feature flag to enable new method of CSRF token generation:

    Feature.enable(:global_csrf_token)

  3. Only then, continue to upgrade to later versions of GitLab.

Custom Rack Attack initializers

From GitLab 13.0.1, custom Rack Attack initializers (config/initializers/rack_attack.rb) are replaced with initializers supplied with GitLab during upgrades. We recommend you use these GitLab-supplied initializers.

If you persist your own Rack Attack initializers between upgrades, you might get 500 errors when upgrading to GitLab 14.0 and later.

12.2.0

In 12.2.0, we enabled Rails' authenticated cookie encryption. Old sessions are automatically upgraded.

However, session cookie downgrades are not supported. So after upgrading to 12.2.0, any downgrades would result to all sessions being invalidated and users are logged out.

12.1.0

If you are planning to upgrade from 12.0.Z to 12.10.Z, it is necessary to perform an intermediary upgrade to 12.1.Z before upgrading to 12.10.Z to avoid issues like #215141.

12.0.0

In 12.0.0 we made various database related changes. These changes require that users first upgrade to the latest 11.11 patch release. After upgraded to 11.11.Z, users can upgrade to 12.0.Z. Failure to do so may result in database migrations not being applied, which could lead to application errors.

It is also required that you upgrade to 12.0.Z before moving to a later version of 12.Y.

Example 1: you are currently using GitLab 11.11.8, which is the latest patch release for 11.11.Z. You can upgrade as usual to 12.0.Z.

Example 2: you are currently using a version of GitLab 10.Y. To upgrade, first upgrade to the last 10.Y release (10.8.7) then the last 11.Y release (11.11.8). After upgraded to 11.11.8 you can safely upgrade to 12.0.Z.

See our documentation on upgrade paths for more information.

Maintenance mode issue in GitLab 13.9 to 14.4

When Maintenance mode is enabled, users cannot sign in with SSO, SAML, or LDAP.

Users who were signed in before Maintenance mode was enabled will continue to be signed in. If the admin who enabled Maintenance mode loses their session, then they will not be able to disable Maintenance mode via the UI. In that case, you can disable Maintenance mode via the API or Rails console.

This bug was fixed in GitLab 14.5.0 and backported into 14.4.3 and 14.3.5.

LFS objects import and mirror issue in GitLab 14.6.0 to 14.7.2

When Geo is enabled, LFS objects fail to be saved for imported or mirrored projects.

This bug was fixed in GitLab 14.8.0 and backported into 14.7.3.
