What is CircleCI?

CircleCI Server 4.10.2 and 4.9.7 carry the eMudhra distrust to self-hosted installs.

CircleCI spent late October on two surfaces. In the cloud product, GitHub check runs now explain on-hold jobs and re-runs run as the person who clicked, and CLI 1.11 can script Slack notifications. On Oct 28, Server 4.10.2 and 4.9.7 stopped trusting the compromised eMudhra intermediates and fixed Details links, proxy-related 500s and a tracing crash loop. Vault is deprecated and will be unsupported in Server 5.0, with a script to migrate to Tink.

What is CRI-O?

CRI-O ships patch releases across three branches with empty change notes

CRI-O's changelog is patch releases across supported branches, now including v1.35.x alongside v1.34.x. The three newest notes, v1.35.10, v1.34.15 and v1.34.14, list empty Dependencies and Feature sections with no items. Earlier 1.34 patches carried dependency updates and regression fixes.

CircleCI Server 4.10.2 and 4.9.7 carry the eMudhra distrust to self-hosted installs.

◆ Current state

CircleCI spent late October on two surfaces. In the cloud product, GitHub check runs now explain on-hold jobs and re-runs run as the person who clicked, and CLI 1.11 can script Slack notifications. On Oct 28, Server 4.10.2 and 4.9.7 stopped trusting the compromised eMudhra intermediates and fixed Details links, proxy-related 500s and a tracing crash loop. Vault is deprecated and will be unsupported in Server 5.0, with a script to migrate to Tink.

◆ Where it's heading

The platform keeps pulling identity and permission checks onto the real actor: scoped tokens, V3 OIDC claims and re-run attribution. The self-hosted line follows with its own permission and link repairs. Server 5.0 is taking shape as a breaking release, at least for secret storage.

◆ Prediction

Expect more Server 4.x patches ahead of 5.0, with Tink migration guidance repeated until Vault support ends.

CRI-O ships patch releases across three branches with empty change notes

◆ Current state

CRI-O's changelog is patch releases across supported branches, now including v1.35.x alongside v1.34.x. The three newest notes, v1.35.10, v1.34.15 and v1.34.14, list empty Dependencies and Feature sections with no items. Earlier 1.34 patches carried dependency updates and regression fixes.

◆ Where it's heading

The project is in steady maintenance on several Kubernetes-aligned branches. The published notes have stopped describing changes, so users cannot see what a patch contains from the feed.

◆ Prediction

More patch releases on 1.34 and 1.35 are likely at the same cadence; whether notes will return is unclear.
