What is CircleCI?

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

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.

What is Semgrep?

Semgrep 1.185 drops the SSH server from its Docker image and sharpens PHP call resolution.

Semgrep keeps a weekly cadence on two tracks, matcher depth and Supply Chain. 1.185 resolves virtual calls through basic PHP trait composition, extends range-based requirements.txt findings to the native resolver, adds structured JSON execution logs and secrets-validator telemetry, and removes sshd and sftp-server from the semgrep/semgrep Docker image. A 3% median scan speedup comes from simpler dataflow variable keys.

6.3

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

◆ 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.

5.0

Semgrep 1.185 drops the SSH server from its Docker image and sharpens PHP call resolution.

◆ Current state

Semgrep keeps a weekly cadence on two tracks, matcher depth and Supply Chain. 1.185 resolves virtual calls through basic PHP trait composition, extends range-based requirements.txt findings to the native resolver, adds structured JSON execution logs and secrets-validator telemetry, and removes sshd and sftp-server from the semgrep/semgrep Docker image. A 3% median scan speedup comes from simpler dataflow variable keys.

◆ Where it's heading

Supply Chain is closing the gaps where unpinned Python requirements used to go unseen, now in both resolvers. Alongside, Semgrep is investing in operability: structured logs, telemetry and a smaller container attack surface suggest more customers run it in their own pipelines and want to audit it.

◆ Prediction

Expect the requirements.txt range logic to spread to other ecosystems with loose version specs, and more structured log events following SEMGREP_LOG_JSON_FILE.
