CircleCI will be moving to twice-yearly major and minor version releases of Server. Releases will be targeted for Spring (April) and Fall (October). Patch releases for bugs and security updates will be made monthly as needed.

We will support two minor releases or 1 year from the date of the release. This is a change from the current 4 minor releases or 1 year from the date of the release. After the April release of server 4.8, supported versions of server will include server 4.8 and server 4.7.

A catch-up release will be made available in the coming months that will allow existing customers to upgrade from 4.3, 4.5, and 4.6 variations to the most recent server version 4.7. Allowing customers to get to a supported version before we release 4.8 in April.

Server release 4.8 is planned to include some new features. The first enables more flexibility in defining which jobs or workflows run using conditional expressions. The second is the introduction of an observability stack that will enable proactive monitoring of the state of the server installations.

What’s changed?

• Authenticated users are now redirected from /server-login to the app subdomain’s dashboard.
• Users who require admin approval before logging in will now see an error message on the login screen.
• Improved error handling when retrieving pipeline values from GCS
• Default resource class can now be set via Repl.
• Project-based context restrictions now populate the project list.
• ~Improved k8s runner start up times. Task agent will now be initialized via init image rather than waiting to copy over the agent after the task pod has started.~

Update: Aug 12, 2024. We discovered that the init container changes were not included in this release and have updated the change log.

Before Upgrading

See the CircleCI server 4.3 release notes and upgrade guide for this release.

There is a background database migration job that is run on install/upgrade to server 4.3. Customers upgrading to 4.3 must ensure this job completes. Full details can be found in the Upgrade guide.

When upgrading from server v3.x you will need to install v4.0 and then follow the recommended upgrade path before installing this version.

What’s New in Release 4.3.1

CHANGES

• Removes non-configurable settings from values.yaml for Runner admin to reduce complexity
• Adds logic to check for suspended or deleted GitHub users before fetching config with OAuth tokens

KNOWN ISSUES

• The job concurrency limit per organization is hardcoded to 2500. This limit is configurable from version 4.3.2 onwards.
• Vault may not refresh its client token after a month of uptime.
• Retry with SSH for jobs using the machine executor advertises a private IP address. For this reason, retry with SSH for jobs using the machine executor works as standard for public installations, but for private installs you would need to ensure that you can access the private IP advertised. For example, by using a VPN into your VPC.
• CircleCI 1.0 builds are not supported. If an attempt is made to run a 1.0 build, no feedback will be available in the application to indicate the cause of the issue. If a build is run on your installation and does not show up in the CircleCI application, users should be directed to use the CircleCI CLI to validate the project configuration and get details of the possible cause of the issue.

To learn more about Server 4.3 installation, migration, or operations please see our documentation.

Before Upgrading

See the CircleCI server 4.2 release notes for upgrade notes for this release.

When upgrading from server v3.x you will need to install v4.0 before installing this version.

What’s New in Release 4.2.1 & 4.1.5

Changes

• Introduced the ability to disable the org-level concurrency limit in distributor. For more information, see the docs.

Fixes

• Fixed a bug that caused the /v2/tasks and /v2/tasks/running endpoints on the runner API to return errors.
• Fixed a bug that caused the self-hosted runners page to appear in the side navigation, but this page is unsupported on server at this time.
• Fixed a bug that caused the Insights page to crash if a user tried to view job resource usage, which is is unsupported on server at this time.
• Fixed a bug where the NGINX Deployment replicas were hard-coded to 1 and did not respect the nginx.replicas value in the Helm values.yaml file.

Fixes

• Query parameters are now supported on the task-agent download endpoint.

Known Issues

For example, by using a VPN into your VPC.
• CircleCI 1.0 builds are not supported. If an attempt is made to run a 1.0 build, no feedback will be available in the application to indicate the cause of the issue.

• Before upgrading to v3.4.x, delete the deployment named circleci-server-kube-state-metrics.
• Prometheus is broken in KOTS versions 1.65.0 - 1.67.0. If you rely on this feature, do not upgrade your KOTS version until this issue has been resolved.
• Retry with SSH for jobs using the machine executor advertises a private IP address. For this reason, retry with SSH for jobs using the machine executor works as standard for private installations, but for public installations you would need to ensure that you can access the private IP advertised (for example, by using a VPN into your VPC).

Fixes

• For runner installations on server, you can now directly clone a repository with just the checkout step in .circleci/config.yml.

Known issues

• When migrating from 3.x to 4.x, workflow configuration migrations will run as an init job and the workflows-conductor-event-consumer and the workflows-conductor-grpc-handler pods will not start until the migration completes. Customers with large PostgreSQL databases should plan accordingly. Migration time can be reduced by scaling the workflow-conductor pods.
• Vault may not refresh its client token after a month of uptime.

What’s New in Release 2.19.14

Notes

In March 2022 updates to CircleCI server v2.x will stop. Support for customers using CircleCI server v2.x will continue.

• There has been a change to how you will checkout using tags in jobs. Branch tags will now be referenced by either CIRCLE_TAG or +refs/heads/tag/path. For example, git checkout --force "$CIRCLE_TAG" or git fetch --force origin '+refs/heads/master:refs/remotes/origin/master'

Fixes

• Security patches for the exim image
• Replaced deprecated GitHub API endpoint for teams

Known Issues

• On static (non-AWS) installations with NONE selected under storage driver settings, tests can be split only by file name or file size. If a user attempts to split tests by timing data, static instances will split them by file name instead.
• If any changes have been made to your networking configuration from the default, you should run the following steps to ensure you can use SSH to inspect your builds (for further information on SSH reruns see the SSH Rerun Guide):
  • For customers using AWS, make sure that you have the latest Launch Configuration configured for Nomad clients, and that exiting Nomad clients were spun up using the Launch Configuration.
  • On each Nomad Client machine, create /etc/circleci/public-ipv4
  • This file should contain the public (if applicable) or private IP of the nomad client

What’s New in Release 3.3.1

Fixes

• Removed outdated cert trust stores from some images. They were found to be causing access issues to some server installations.
• Fixed a bug that was affecting runner updates.
• SSH reruns now work when server is installed behind a proxy.
• Replaced deprecated GitHub API endoint for teams.

Known Issues

• Retry with SSH for jobs using the machine executor advertises a private IP address.

What’s New in Release 3.2.2

Notes

• The rerun workflow endpoint now returns workflow ID rather than the message accepted.

Fixes

• TLS is terminated outside of frontend so the SSL server has been completely removed from the frontend container.
• Moved the default certificate logic from KOTS to helm.
• Fixed the build agent image version used in server v3.x. The image used previously was causing problems with runner.

Known Issues

• Retry with SSH for jobs using the machine executor advertises a private IP address.

If a build is run on your installation and does not show up in the CircleCI application, users should be directed to use the CircleCI CLI to validate the project configuration and get details of the possible cause of the issue.

• Runner cannot be used when server is installed behind a proxy.
• Let’s Encrypt certificate generation does not work. You will need to provide your own certificates or use the default certificates provided.
