What is Apereo CAS?

Apereo CAS 8.1.0 reaches a third release candidate with 8.0.0 still not final.

CAS runs long release-candidate trains. 8.0.0 reached RC6 in June without a final in this feed, and the 8.1.0 line has since moved through RC1 in August, RC2 in September and RC3 in October. A 7.3.7.1 patch in June fixed a published OIDC vulnerability on the maintenance branch. The release entries list only documentation links and contributor credits, so their contents are not visible here.

What is Skipper?

Skipper now serves zone-filtered routes only when its own ingress is balanced across zones.

Skipper, Zalando's HTTP router and Kubernetes ingress, tags a release for nearly every merge, so most entries are dependency bumps. The substantive ones this autumn are about zone-aware routing: v0.28.56 made routesrv recompress only zones whose routes changed, and v0.28.60 on November 2 serves zone-filtered routes only when skipper-ingress is balanced across zones, falling back to the global table otherwise.

Apereo CAS 8.1.0 reaches a third release candidate with 8.0.0 still not final.

◆ Current state

CAS runs long release-candidate trains. 8.0.0 reached RC6 in June without a final in this feed, and the 8.1.0 line has since moved through RC1 in August, RC2 in September and RC3 in October. A 7.3.7.1 patch in June fixed a published OIDC vulnerability on the maintenance branch. The release entries list only documentation links and contributor credits, so their contents are not visible here.

◆ Where it's heading

Candidates arrive about monthly, and 8.1 has overtaken 8.0 as the active line. Without notes in the entries, the feed tracks timing rather than content.

◆ Prediction

An 8.1.0-RC4 or an 8.1.0 final is the next likely entry, on the same roughly monthly rhythm.

Skipper now serves zone-filtered routes only when its own ingress is balanced across zones.

◆ Current state

Skipper, Zalando's HTTP router and Kubernetes ingress, tags a release for nearly every merge, so most entries are dependency bumps. The substantive ones this autumn are about zone-aware routing: v0.28.56 made routesrv recompress only zones whose routes changed, and v0.28.60 on November 2 serves zone-filtered routes only when skipper-ingress is balanced across zones, falling back to the global table otherwise.

◆ Where it's heading

Zone-aware routing is being made safe for production, with guards against skew and fixes for a data race and silent misconfiguration. It currently works only in the routesrv mode, and the release notes say the direct Kubernetes mode needs the same filtering.

◆ Prediction

Expect zone filtering to be extended to the skipper-to-Kubernetes mode in a coming tag, as the v0.28.60 notes say is needed.
