New Feature: Workflows UI will now show actors who have taken the following actions:

• Rerun workflows
• Approved jobs
• Canceled jobs

New Feature We are excited to announce more Metrics! Nomad job metrics can be enabled and will be emitted by the Nomad Server. Please see Nomad Metrics documentation for instructions on how to configure Nomad Clients. The following five types of metrics are reported:

• circle.nomad.server_agent.poll_failure: Returns 1 if the last poll of the Nomad agent failed, otherwise it returns 0.
• circle.nomad.server_agent.jobs.pending: Returns the total number of pending jobs across the cluster.
• circle.nomad.server_agent.jobs.running: Returns the total number of running jobs across the cluster.
• circle.nomad.server_agent.jobs.complete: Returns the total number of complete jobs across the cluster.
• circle.nomad.server_agent.jobs.dead: Returns the total number of dead jobs across the cluster.

New Feature Host (Services VM) and docker metrics can now be forwarded via Telegraf , a plugin-driven server agent for collecting & reporting metrics, to DataDog or a custom location. To enable and/or configure please go tohttps://example.com/settings#metrics. For more information please see the Monitoring documentation.

Performance Improvement Reduced the load time for all workflows pages.

Performance Improvement CircleCI has upgraded the mechanism that returns gettimeofday calls. As a result, heavy users of syscall will see an aggregate improvement in performance. Most noticeably this will improve the run time of projects with heavy usage of debugging/profiling tools and Xdebug with PHP.

Updated JVM_HEAP_SIZE is configurable for frontend, output-processor, and test-result containers. Please see JVM Heap Size Configuration documentation.

Updated For customers running the Static installation, Ubuntu 16.04 (Xenial) has been added as a supported OS. For additional details please see the docs.

What’s New

Preview of improved builds service

CircleCI has developed an improved builds service that is ready for preview. The improved build service is the first step to a healthy roadmap of parameterized commands, config reuse across projects, improved DRY support, and better error reporting.

A preview is currently available for a few of our most adventurous organizations this week, and we plan on rolling it out to more projects in the coming weeks before it is publicly available. If you are adventurous and want to switch to the new service, be sure to read the preview docs before requesting approval.

What’s New in Release 2.14

This release contains service migrations for contexts and is a required upgrade. The following updates and fixes are also of note:

Fixed: Pre-allocated VMs not being used. Customers reported that jobs using machine executor and setup_remote_docker were continuing to spin up (and terminate) new VMs at runtime instead of the pre-allocated pool.

Fixed: Unable to build in AWS region eu-west-2.

Updated: The title of the Builds page in the CircleCI application was changed to Jobs in several places to better reflect the structure of builds.

Updated: Contexts are now checked for unique naming across your installation of CircleCI instead of just within an organization. You will no longer be able to create duplicate context names within an account. Existing duplicates will be honored by the system, but should be changed to avoid future collisions. Please see the Contexts documentation for further information.

Updated: The test-results services cleans up the /tmp directory on restart and the JVM heap size increased from 256m to 512m.

Known Issue(s)

When a saved context is removed during the build graph phase it can cause a silent failure during job execution.
When using the none storage driver, the cache will not be saved. This means that you currently cannot use caching in CircleCI when you are using the none storage driver.

Migration Tools: The 1.0 migration center was updated with additional content and helpful tools to migrate projects from CircleCI 1.0 to 2.0.

What’s New

The following features and additions are now available.

• New Workflows Feature: If your project has a large number of tests, you can use the circleci tests split command to reduce your job run time. This feature is now supported with Workflows. For more information on how to set up test splitting, see the Splitting Test Files section of the Running Tests in Parallel documentation.

• EOL Tools: The 1.0 migration center has been updated with additional content and helpful tools.

• Performance Improvement: CircleCI has upgraded the mechanism that returns gettimeofday calls. As a result, heavy users of syscall will see an aggregate improvement in performance. Most noticeably this will improve the run time of projects with heavy usage of profiling tools and Xdebug with PHP.

• Added: This release adds a Plan Overview page for customers on the Performance pricing plan to enable Admins to see their selection from the Settings.

• Added: Customers who are still building on CircleCI 1.0 will now get a reminder to upgrade to CircleCI 2.0 in build emails.

What’s New in Release 2.13*

• Fixed: Due to a certificate not being imported jobs were unable to submit after a container restart.
• Fixed: Stability issues within contexts service.
• Fixed: vm-service issue where AWS ECS and EBS volumes were left used. Added better idempotent client retries, API eventual consistency handling.
• Added: vm-service EBS Volumes cache evictor. Docker Layer Caching EBS volumes get deleted after 14 days of unused. You can control the inactivity period in Installation Admin Settings page.
• Added: Periodic checks to scale down any unused long running instances (e.g. due to reduction in prescaling configurations, or or due to a bug preventing termination of VMs in timely manner).
• Added: Optimizations to speed up provisioning. Resiliency to network/external changes.
• CircleCI is excited to announce that users on AWS can now forward host (Services VM) and docker metrics via Telegraf , a plugin-driven server agent for collecting & reporting metrics, to AWS CloudWatch. This is is the first step into bringing you greater observability into your installation. To enable and configure please go tohttps://example.com/settings#metrics. In this release the following metrics may be enabled: Docker , Networking , Disk , Memory, and CPU. For more information please see the Monitoring documentation.
• CircleCI is enhancing visibility by capturing usage statistics of CircleCI installations. This aggregate data will be used to better support you and ensure a smooth transition off 1.0. This optional feature is automatically available when you upgrade to the latest version of your installation or once a support bundle is downloaded. Below are the metrics being captured. If you would like access to this data in order to better understand your users please contact a CircleCI account representative. Please reference exhibit C within your terms of contract and our standard license agreement for our complete security and privacy disclosures.

• An issue involving pre-allocated remote docker, machine VM creation, and other VM usage on AWS when the on-host VM option is selected has been fixed.

• An issue with the VM provider timing out when waiting for SSH to connect has been fixed. This upgrade supersedes any custom values for the Number of SSH attempts for starting VM setting and adds an equivalent field named Timeout for waiting for SSH to connect to VM(s) that you must set.

The installable version of CircleCI 2.6.0 includes the following fixes and improvements:

• It is now possible to create multiple Contexts in the Organization Settings of the CircleCI app. See the Contexts documentation for details and naming conventions.

The installable version of CircleCI 2.5.0 includes the following fixes and improvements:

• This release fixes a problem with DNS resolution failure on alpine-based containers. This problem was observed in the 2.3 release and was fixed for some service containers in 2.4. The 2.5 update fixes the issue for all service containers.
• This release includes improvements to scaling and garbage collection in the VM Service that should improve performance for installations with heavy use of machine executors or remote Docker.

The installable version of CircleCI 2.4.0 includes the following improvements and changes:

• Audit logging - This feature makes available a downloadable log of system events from the CircleCI Admin dashboard. This is the first release of audit logging; more events and improved data in the logs will be delivered in subsequent releases. Find detailed information about the data fields for each event in the Audit Logging section of the Security Features document.

• LDAP integration - It is possible to enable a new CircleCI installation to authenticate users with OpenLDAP or Active Directory credentials. New installations may be configured to have users authenticate through LDAP, including Active Directory support. Refer to the Authentication document for instructions.

• New build-agent - The new build-agent fixes some cases in which users were unable to log into a running job with SSH.

• VM Service improvements - Autoscaling of the VM Service has been improved, so machine executors should have more consistent performance at scale.

• New visualization for Workflows - When you click on a workflow in the CircleCI application, a diagram appears with the relationship of your jobs to one another and the complete sequence of the workflow.
• Updates to the onboarding flow - We now show a new user only projects already building on CircleCI rather than a list of all projects found in source control. This change was made to prevent inadvertent adding of projects to CircleCI during the onboarding process. We also added a confirmation dialog for any user opting to follow more than six projects and made it clearer how to add new projects not yet building on CircleCI.
• Support for object stores other than S3 - CircleCI 2.2.0 now supports the same object store options that are supported in 1.x. This is a prerequisite to future releases that will allow non-AWS installations of CircleCI 2.x.
• Updates to the VM Service; ACTION MAY BE REQUIRED IF YOU ARE USING AWS - The VM service has been updated to use volumes rather than persistent instances. This change allows operators to accommodate Docker Layer Caching with a smaller number of long-running VMs. If you installed using the suggested IAM permissions from prior versions you must update your IAM permissions with this upgrade. Refer to the policy template for the complete set of permissions.
• New Contexts feature; ACTION MAY BE REQUIRED IF YOU ARE USING THE HIGH AVAILABILITY CONFIGURATION - The Contexts feature uses a HashiCorp Vault secure storage mechanism. If your installation is running in HA mode, HashiCorp Vault needs to be externalized similar to the Mongo and Postgres databases. Refer to the Configuring High Availability documentation for instructions.
