What’s new in Release 4.5.0

The v4.5 release introduces security and performance improvements.

New features

• You can now restrict access to contexts using expression restrictions. Read more in the docs.
• You can now configure the Nomad Autoscaler evaluation_interval and cooldown.

Changes

• Very large and complex configuration files, notably those using a high number of pipeline parameters, will now have a shorter compile time.
• Optimizations have been made in orb-service for a reduction in both storage space used and timeouts for very large configuration compilation.
• The login page has been replaced with a new one. When logging in to server now you will be redirected to /server-login. The banner from the login page has been removed.
• Selecting items in the navigation bars of the settings pages no longer triggers a full page reload.
• Project and personal access tokens are now hashed rather than being stored as plaintext.
• Obsolete caches have been removed leading to improve Workflows Conductor performance and reduced Redis usage.
• Required domain-service caching variables are now defined by default.
• Various changes have been made in the UI to standardize style and icon usage.
• CircleCI 1.0 notify feature will no longer function, outbound webhooks should be used in the place of the notify feature
• We are introducing parameter limits to improve responsiveness of the trigger pipeline API and limit potential abuse. The new limits will be as follows: 100 max entries, 128 maximum key length, 512 maximum value length.

Bug fixes

• Fixed a bug that was causing duplicate workflows showing in the UI.
• Fixed a bug that was causing config compliation checks to attempt to access an invalid subdomain.
• The self-hosted runners Create Resource Class button in the web app has been fixed.

New services

New services introduced with this release:

• ciam-gateway
• ciam
• web-ui-authentication

Database migrations

The following databases will run migrations when upgrading to this version:

• builds_service
• permissions
• runneradmin
• conductor_production

Known issues

• Vault may not refresh its client token after a month of uptime. Migrate to Tink to resolve this issue.
• 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, use the CircleCI CLI to validate the project configuration and get details of the possible cause of the issue.
• Customers installing Server to GKE should wait to upgrade until further notice. There is an issue preventing a successful upgrade. New installations are not impacted.

Fixes

• Fixed a bug that caused the Runners page to appear in the side navigation on the Projects page, which is unsupported on server at this time.
• Fixed a bug that caused the Docker Layer Caching (DLC) settings to appear in Project Settings, which is only supported in server 4.3+.
• Bumped Nomad Autoscaler to version 0.3.7 to resolve an upstream regression that broke the default AWS credential chain for Nomad.

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 4.3.0

The v4.3 release introduces upgraded execution architecture. Previously, VM service was responsible for creating virtual machines for machine and remote Docker jobs. This has been replaced with machine provisioner. The new architecture has improved efficiency and stability. This upgrade also brings server inline with CircleCI cloud execution, meaning server will benefit from future updates faster. Some specific benefits include:

• A new UI for step output, which is better at handling larger output and colour.
• New systems for processing job output (step data, caches, artifacts etc.) is much more efficient.
• Machine and remote Docker jobs no longer run through Nomad so compute costs are cut down significantly.
• You do not need to run a Nomad cluster if you just want to run machine (and/or remote Docker jobs) on your server instance.
• DLC is now configured to run through S3, which is cheaper than running on SSD volumes, and there is no longer a limit on the amount of DLC jobs that can be run in parallel. DLC stays more consistent with better pruning and is shared between all jobs in a project instead of each cache being different.
• VM service could fall back to another region/zone, but machine provisioner can handle gaps in availability through:
  • Distributing load across availability zones through round-robining
  • Sending a percentage of traffic to a different zone
  • Instance type fallbacks based on deficits and success

New features

• Server execution architecture has been upgraded from VM service to machine provisioner. For further information, see the Installation guide.
• Server now ships with a custom postgreSQL image which now supports pg_crypto, pg_partman, and pg_cron support extensions.
• Added a REPL toggle to turn on a background which deletes workflow data older than 1 year. This is off by default.
• Config policies are now fully supported on server. _compiled_ is now a reserved word in config policies, so that parameterized configuration is fully available to the config policies engine. For further information see the Config policies overview docs.
• The circleci env subst command is now supported. See the Environment variables docs for more information.
• Added support overriding non-CircleCI-managed images.

Changes

• Nomad Autoscaler has been updated to 0.3.7.
• Server no longer deploys the Prometheus chart.
• The artifact paths have changed to improve download performance. The new path will now be <server-domain>/output/job/<job-id>/artifacts/0/home/circleci/artifacts/<artifact-file>

• If a job is retried due to an infrastructure failure, it should no longer cause a workflow to get stuck
• Fixed a bug that would try and pull a project’s config with a suspended user’s token.

Known issues

• All pipelines must re-run from start due to architectural changes.
• 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.

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.

From server v4.2, CircleCI server auto-generates some secrets if they are not present in the Kubernetes namespace. If you are upgrading from v4.1.x to 4.2, and you have managed Kubernetes secrets yourself, you will need to follow the steps outlined in the CircleCI server 4.2 upgrade guide to ensure the system knows some secrets already exist.

What’s New in Release 4.2.0

New Features

• Config policies now available as a preview on server. Use config policies to create organization-level policies to impose rules and scopes to govern which configuration elements are required, allowed, not allowed etc. See the Config policies overview for guidance on setting up config policies. To use config policies CLI commands with server v4.2, append all commands shown in the docs with --policy-base-url https://<CIRCLECI-SERVER-DOMAIN>.com
• You can now find your current server version by running: curl http(s)://<CIRCLECI-SERVER-DOMAIN>/version
• The 2xlarge+ resource class (32 vCPUs, 64 GB RAM) is now available for use with the Linux VM execution environment

Changes

• Introduced the ability to disable the org-level concurrency limit in distributor. For more information, see the docs
• By default, Server 4.2 auto-generates some secrets. If you wish to manage these secrets yourself, you should create these secrets (if not done already) and ensure Helm is aware so that auto-generation is skipped. See the CircleCI server 4.2 upgrade guide for steps.
• RabbitMQ version upgraded from 8.6.4 to 11.15.1.

• 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.
• 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.

What’s New in Release 3.2.0

New Features

• Customers who require a fully private installation can now access a setting in the KOTS admin console to ensure public IPs are not assigned to VMs. Note that with this non-public IP setting enabled, a work-around will be needed if SSH access to running jobs is required, for example, by using a VPN into your VPC.
• Customers that manage outbound traffic through a proxy can now configure proxy settings through the KOTS admin console. Please see our documentation for specifics on proxy support for server.
• We have expanded the machine execution environment options available to include additional resource classes, sizes, and executors. You now have access to Arm (medium, large), Linux (medium, large, X large, and XX large), and Windows (medium, large, XX large) resource classes.
• The insights API is now available to all server customers. Leverage build and other data to better understand the performance of teams and the health of your build and testing efforts.
• We have revamped the admin UI, and updated our installation instructions, making it easier to set up and manage server.
• You can now supply a custom Linux AMI for VM service.
• SSL termination can now be disabled - If you have put server login behind a firewall, this will enable SSL termination at the firewall.
• You can now control the size of persistent volumes. For larger customers, the initial persistent volume size was too small, by default. You can now set this at install time, providing an easier migration for those customers that require it. For further information see the Internal Database Volume Expansion doc.
• We have added an auto-scaling example to the nomad client terraform.
• You can now choose to serve ‘unsafe’ build artifacts. Previously this option was hidden, meaning potentially unsafe artifacts were rendered as plain text. For more information see the Build Artifacts doc.

Fixes

• The default windows executor was not as documented, we have increased the size to align with documentation and cloud.

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.

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

Before Upgrading

IMPORTANT: With this release, the frontend-external load balancer has been removed. The traefik load balancer now handles all incoming traffic. When updating from a previous server 3.x version, you will need to update the DNS record that was pointing to the frontend-external load balancer and have it point to the circleci-server-traefik load balancer instead. Remember, you can retrieve the external IP address or DNS name of your traefik load balancer by typing kubectl get svc/circleci-server-traefik in a terminal that has access to the cluster.

For further information see the What’s New doc.

What’s New in Release 3.1.0

New Features

• Telegraf plugins can now be added to server and customized to use third party monitoring solutions, for example, Datadog. For more information, see the Metrics and Monitoring doc.
• The option to use only private load balancers has been introduced for customers who want a fully private installation. For more information see the Load Balancers guide.
• Server 3.x hosts build artifacts, test results, and other state in object storage. We support any S3-compatible storage and Google Cloud Storage. For more information, see the Installation guide for further information.
• Dynamic config via setup workflows is now available on server installations. For more information see our blog post and the Dynamic Configuration docs page.
• Runner is now available on server. For further information, including installation steps, see the Runner docs. Runner allows the use of the macOS executor in server installations and VM service functionality for customers with server installed in a private data centre.
• The frontend load balancer from v3.0 has been removed and replaced with an Ingress resource and the Traefik Ingress controller. This is a breaking change requiring you to reconfigure your DNS. See the What’s New in server docs for further information and guidance.
• The following services can now be externalized. For setup information, see the server v3.x installation guide:
  • Postgres
  • MongoDB
  • Vault
• Backup and restore functionality is now available. For more information see the Backup and Restore guide.
• Prometheus is now deployed by default with server to monitor your cluster health and usage. Prometheus can be managed and configured from the KOTS admin UI. For further information, see the Metrics and Monitoring doc.
• Server now supports the 2XL resource class. The Nomad cluster needs to be made large enough to account for larger resource classes.
• The lifecycle of build artifacts and test results can now be configured from the KOTS admin console under Storage Object Expiry, including the option to disable the expiration and retain artifacts and test results indefinitely.

Fixes

• Resolved a collection of bugs that were causing sensitive information to be leaked into CircleCI support bundles:
  • Instances of faulty and partial redactions of secrets were detected, in part due to 3rd party bugs.
  • PostgresDB leaking sensitive information to STDOUT.
  • Several CircleCI services were logging secrets.
• Tightened network security in the Nomad terraform module.
• Terraform v0.15.0 and up are now supported.

• Resolved a bug that caused contexts-service to fail on expiration of Vault client tokens.
• Resolved a bug that was causing legacy-notifier to report readiness prematurely.
• The JVM heap size parameter has been removed for all services. The heap size is set to be half of the memory limit.
• Changes to networking config and certs are now picked up automatically by Traefik. Previously, a restart would have been required.
• Minimum requirements for CPU and memory have changed. For the new values, see the Installation Prerequisites doc.

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.

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 3.0 installation, migration, or operations please see our documentation.
