What is Apereo CAS?

Apereo CAS opens an 8.1 line while 8.0 is still working through release candidates.

CAS is running a long release-candidate train. The 8.0.0 line reached RC6 in late June after RC4 and RC5 in spring, and 8.1.0-RC1 has now appeared in August. A 7.3.7.1 patch in June addressed a published OIDC vulnerability on the maintenance branch. The release entries themselves carry only navigation links and contributor credits, so feature detail is not visible here.

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.

Apereo CAS opens an 8.1 line while 8.0 is still working through release candidates.

◆ Current state

CAS is running a long release-candidate train. The 8.0.0 line reached RC6 in late June after RC4 and RC5 in spring, and 8.1.0-RC1 has now appeared in August. A 7.3.7.1 patch in June addressed a published OIDC vulnerability on the maintenance branch. The release entries themselves carry only navigation links and contributor credits, so feature detail is not visible here.

◆ Where it's heading

Two lines are moving at once, which suggests 8.0 is close enough to final that work has begun branching forward rather than that the RC train has stalled. The contributor lists stay small and consistent across releases - a handful of recurring maintainers - and security handling happens on the older supported branch, as it should.

◆ Prediction

An 8.0.0 final is the obvious next milestone given RC6 was three months ago and an 8.1 branch is already open. The release bodies do not describe features, so what it contains cannot be read from this feed.

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.
