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 Routinator?

Routinator 0.16 will validate ASPA and BGPsec, and run strict, by default

Routinator is a mature RPKI validator with a slow, release-candidate-gated cadence. After a run of security work, including an external audit's four CVEs in 0.15.2 and resource-exhaustion fixes in 0.15.3, 0.16.0-rc1 changes defaults: ASPA and BGPsec are on, strict validation is on, and the old enable flags become --disable-aspa, --disable-bgpsec and --relaxed. It also adds Resource Signed Checklists (RFC 9323), SLURM v2 with ASPA filtering, and a new repository logging scheme that changes the /status JSON.

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.

Routinator 0.16 will validate ASPA and BGPsec, and run strict, by default

◆ Current state

Routinator is a mature RPKI validator with a slow, release-candidate-gated cadence. After a run of security work, including an external audit's four CVEs in 0.15.2 and resource-exhaustion fixes in 0.15.3, 0.16.0-rc1 changes defaults: ASPA and BGPsec are on, strict validation is on, and the old enable flags become --disable-aspa, --disable-bgpsec and --relaxed. It also adds Resource Signed Checklists (RFC 9323), SLURM v2 with ASPA filtering, and a new repository logging scheme that changes the /status JSON.

◆ Where it's heading

Having spent 2026 hardening the validator, the maintainers are now changing what operators get out of the box. Defaults moving toward ASPA and strictness put newer RPKI object types on equal footing with route origin validation.

◆ Prediction

A final 0.16.0 following one or more release candidates is the likely next step, as with 0.15.0.
