Releasesby IbisAdditional AWS fallback regions for machine executor and remote Docker
UpdateyesterdayUnverifiedAdded Oct 15, 2026
We are adding two AWS compute regions, us-west-1 and us-west-2 . They join us-east-2 as fallback regions. CircleCI uses a fallback region when capacity is not available in the primary region. This change improves availability. What is affected Machine executor jobs and remote Docker can run in a fallback region.

Every CircleCI releaseSmarter Testing is now generally available
Smarter Testing is now generally available for all Cloud customers. Since beta, teams have used test impact analysis, dynamic test splitting, and automatic rerun of failed tests to run fewer tests, run them faster, and get signal sooner, while maintaining full confidence. What’s included Smarter Testing is a comprehensive set of testing capabilities.
Xcode 27.1 Available
The Xcode 27.1 image is now available to be used in CircleCI pipelines. The full manifest of installed software can be found here .
Machine Runner Orchestrator Release 1.0.1
New Run runner VMs on spot nodes to cut compute costs, without failing jobs when a node is reclaimed. Set runner.enableUnsafeRetries on a resource class, and a job that is still running when its VM shuts down is retried on another VM instead of failing. The job restarts from the beginning, so only enable it for jobs that are safe to run more than once.
Runner Release 3.1.13
Machine Runner: Run machine runners on spot or preemptible instances to cut compute costs, without failing jobs when an instance is reclaimed. With the new runner.enable_unsafe_retries option, a job that is still running when the runner receives SIGINT , SIGTERM or SIGHUP is retried on another runner instead of failing.
Introducing Gen2 Arm Resource Classes (Beta)
Gen2 Arm resource classes for Docker and Linux VM / Remote Docker are now available in Beta on CircleCI, delivering priority access to newer-generation Arm CPUs that are up to 94% faster than gen1 for your Linux workloads, at a lower credit cost.
The CircleCI plugin for JetBrains IDEs: watch, debug and manage your runs without leaving the IDE
The CircleCI plugin for JetBrains IDEs is now available on the JetBrains Marketplace . It brings your CircleCI runs, jobs and config into IntelliJ IDEA and the other JetBrains IDEs, so you can see what CI is doing and act on it without switching to the browser.
Teardown now available for run steps
For customers needing cleanup work to run no matter how a job ends, we now support teardown steps. Add a teardown list to any run step, and CircleCI runs those steps at the end of the job, including when the job fails, is canceled, or times out.
Approve or cancel on-hold jobs directly from Slack
Slack notifications for on-hold workflows are now actionable. When a workflow is paused at an approval job, the Slack notification includes Approve and Cancel buttons, so you can act on it without opening the CircleCI web app. The buttons appear in both project channel notifications and direct messages, and each action asks for confirmation before it runs.
