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.

What is NGINX?

nginx patched HTTP/3 twice in a month and is trimming old platform code on mainline.

nginx runs a 1.31 mainline and a 1.30 stable line. After 1.31.5 added a native control API, a JSON module and predicate locations in September, the following releases were mostly security: 1.31.6 and 1.30.5 fixed an HTTP/3 buffer overflow (CVE-2026-90439), then 1.31.7 and 1.30.6 fixed five more CVEs including HTTP/3 request body injection. 1.31.8 on October 21 removed the Win32 iocp event module and fixed further HTTP/3 issues.

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.

nginx patched HTTP/3 twice in a month and is trimming old platform code on mainline.

◆ Current state

nginx runs a 1.31 mainline and a 1.30 stable line. After 1.31.5 added a native control API, a JSON module and predicate locations in September, the following releases were mostly security: 1.31.6 and 1.30.5 fixed an HTTP/3 buffer overflow (CVE-2026-90439), then 1.31.7 and 1.30.6 fixed five more CVEs including HTTP/3 request body injection. 1.31.8 on October 21 removed the Win32 iocp event module and fixed further HTTP/3 issues.

◆ Where it's heading

HTTP/3 has needed fixes in each of the last three mainline releases, two of them CVEs. Mainline is adding features and removing legacy code at the same time, while stable gets the CVE backports.

◆ Prediction

More HTTP/3 fixes on both lines are likely; on mainline, follow-up work on the control API and JSON module is the next feature thread to watch.
