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 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.

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.

5.0

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.
