What’s New

On February 15, 2022, the Ubuntu 14.04 and 16.04 Linux VM images used with our machine executor were deprecated, meaning there will be no new releases or support for these images moving forward. When these images reach end of life (EOL) on May 31, 2022, any pipelines that utilize Ubuntu 14.04 or 16.04 images will fail.

In order to prevent unexpected failures and enable you to begin moving to newer images, CircleCI’s Ubuntu 14.04 and 16.04 Linux virtual machine (VM) images will be temporarily unavailable in late March 2022 and late April 2022, and will become permanently unavailable as of May 31, 2022. During these temporary “brown-out” periods, if you are currently using either of these images, be sure to update your config with a newer Ubuntu machine image before the 14.04 and 16.04 images are removed at the end of May 2022.

For more information about how CircleCI will manage these updates, please see the Deprecating Ubuntu 14.04 and 16.04 blog post.

What’s New

CircleCI now supports Windows Server 2022. CircleCI has released a new Windows Server 2022 image which enables customers using CircleCI’s Windows executors to take advantage of the latest operating system, IDE (Visual Studio 2022), and software from Microsoft.

At this time, the Windows Server 2022 image will co-exist with the Windows Server 2019 image allowing you to have the option to upgrade while not losing support to your existing image.

For more information about this update, please refer to the Discuss post that has details on how to adopt the image.

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

On March 15, 2022, GitHub will be changing which keys are supported in SSH and removing unencrypted Git protocol. As a result of this change, any image you have used in a job from a project created between November 2, 2021 and January 13, 2022 will require a version of OpenSSH greater than or equal to version 7.2.

CircleCI has updated the version of OpenSSH for supported machine images and next-generation Docker convenience images in anticipation of this breaking change.

To avoid pipeline failures on Tuesday, March 15, 2022, CircleCI recommends that if you are using deprecated Machine images or deprecated Docker convenience images, upgrade to a supported image. If upgrading an image is not possible, you can regenerate SSH keys for impacted projects to avoid pipeline failures on March 15, 2022.

For more information regarding this change and how to regenerate SSH keys, please refer to this support article.

Before Upgrading

See the What’s new in server 3.x doc for upgrade notes for this release.

What’s New in Release 3.3.1

Fixes

• CircleCI runner can now be used when server is installed behind a proxy.
• Fixed a bug that was causing some intermittent broken dependency caches.
• 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. For this reason, retry with SSH for jobs using the machine executor works as standard for private installations, but for public 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.
• The KOTS admin console cannot be upgraded if your installation is set up to be behind a proxy. The proxy settings will be deleted and cause the KOTS admin console to break.

To learn more about Server 3.x installation, migration, or operations please see our documentation.

What’s New

A new update has been released for the standard 20.04 Linux images for both amd64 and arm64.

For more detailed information about this update, please see the Linux Machine Executor Images Discuss post.

What’s New

The new Clojure Convenience Image (‘cimg/clojure’) is now generally available. This image replaces the soon-to-be-deprecated legacy image (‘circleci/clojure’).

For more information on this release, please see the CircleCI Discuss post.

You may also find more information in the Clojure image GitHub repository.

What’s New

We have released a new image update for Windows, in addition to an update for Visual Studio 2019 16.11.9.0. You can access these updates via our “edge” tags.

For more information about this update and refresh, please see the Windows image update Discuss post

Before Upgrading

See the What’s new in server 3.x doc for upgrade notes for this release.

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. For this reason, retry with SSH for jobs using the machine executor works as standard for private installations, but for public installs you would need to ensure that you can access the private IP advertised, for example, by using a VPN into your VPC.
• It is currently possible for multiple organizations under the same CircleCI server account to have contexts with identical names. This should be avoided as doing so could lead to errors and unexpected behavior.
• 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.
• The KOTS admin console cannot be upgraded if your installation is set up to be behind a proxy. The proxy settings will be deleted and cause the KOTS admin console to break.
• 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.

To learn more about Server 3.x installation, migration, or operations please see our documentation.
