CircleCI's SSH reruns now open from the browser, through one trusted address.

ci/cddebuggingapi deprecationconfig validationcoding agents
◆Current state
CircleCI is tidying both ends of the pipeline before December. Config warnings become hard failures on December 14, and the v1 project APIs lose their branches field on December 7 after brownouts on November 17 and December 1. On November 12 Rerun job with SSH moved to a single host, ssh.circleci.com, on ports 22 or 443 with fixed IPs, plus a terminal that opens from the job page. Functions, versioned job-setup programs agents can configure, entered beta on November 4.
◆Where it's heading
CircleCI is closing old paths (lenient config, v1 API fields, old Xcode images) while making failures easier to reach: job-linked commit statuses last week, browser SSH this week. The newer Functions beta and API v3 are where users are being steered.
◆Prediction
Expect more debug tools on the job page and further v1 API removals pointing users to v3 before year end.

    CircleCI opens SSH reruns from the browser via one host

    SSH reruns now go through one address and host key, work on port 443 from locked-down networks, and can open as a terminal in the web app. It pairs with last week's job-linked commit statuses: getting from a red build to the failing job takes fewer steps.

    CircleCI drops branches from v1 project APIs on December 7

    The v1 and v1.1 project and settings endpoints lose the branches field on December 7, with full-day brownouts on November 17 and December 1. Another push toward API v3, alongside the October trigger and rerun deprecation.

    Config validation warnings will block pipelines on December 14, 2026

    Configs CircleCI used to tolerate will stop running pipelines on December 14, after a warning-only period. It is the strict foundation the Functions and agent work rely on, and `circleci config validate --next` lets agents apply the fixes.

    Improved commit status links and failure details

    Commit statuses now link to the specific workflow and job and replace 'Your tests failed' with a pointer to the CircleCI CLI. Written for agents as much as people, it follows the GitHub check-run improvements from October.

    Server 4.9.8 moves Nomad clients to Ubuntu 24.04

    The older Server line gets new VM images and Nomad client images on Ubuntu 24.04 to patch two kernel CVEs, and Vault is flagged for removal in Server 5.0. Self-hosted users on 4.9 need to update modules and mirror a new NGINX image before upgrading.
