Functions now available in beta
CircleCI launched Functions in beta, allowing developers and AI agents to define, version, pin, and reuse CI environment setup modules via CLI and MCP server.

Manage a project’s Slack notifications from the CLI
CircleCI CLI v1.11.0 adds commands to manage Slack notifications, allowing developers to script Slack channel configuration across projects.
OIDC tokens: new V3 token format with config source and ref claims
CircleCI now issues a third version of its OIDC (OpenID Connect) token, alongside the V1 and V2 tokens. In V3 the subject ( sub ) claim covers where the code was checked out from and where the pipeline config came from. What’s new Jobs now get the V3 token in $CIRCLE_OIDC_TOKEN_V3 , alongside $CIRCLE_OIDC_TOKEN and $CIRCLE_OIDC_TOKEN_V2 .
Xcode 27.2 Beta 3 Available
The Xcode 27.2 Beta 3 image is now available to be used in CircleCI pipelines. The full manifest of installed software can be found here .
Dynamic Parallelism for Smarter Testing
Instead of always starting with full parallelism as set in the config, Dynamic Parallelism can scale the number of parallel nodes your test job needs depending on the number of tests that were selected by Smarter Testing’s Intelligent Test Selection.
Additional AWS fallback regions for machine executor and remote Docker
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.
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.
Deprecation of v1 and v1.1 Trigger and Rerun APIs, February 1, 2027

CircleCI API v3 is now available
API v3 is CircleCI’s current API version, and all new API development happens in v3. Every endpoint follows the same conventions, so you can predict how the API works without reading a spec for each one: UUID resource IDs instead of project slugs Cursor-based pagination One error format with structured error objects Standard rate limit headers, so tools can...
Self-Hosted Runner: Bitbucket Cloud is retiring SSH access via bitbucket.org
Bitbucket Cloud is retiring SSH access via bitbucket.org on 12 November 2026 and moving it to ssh.bitbucket.org(Atlassian announcement). We are updating CircleCI’s build agent to use the new host so that Bitbucket Cloud checkouts continue to work after the cutover.
