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 Elasticsearch?

Elastic moves to 9.5 and takes cross-project search GA on Serverless.

Elastic Stack is now maintained on the 9.5, 9.4 and 8.19 lines, with patch releases arriving together across branches. The one substantive move is cross-project search reaching GA on Serverless, which links projects and queries them from one Discover or ES|QL session.

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.

Elastic moves to 9.5 and takes cross-project search GA on Serverless.

◆ Current state

Elastic Stack is now maintained on the 9.5, 9.4 and 8.19 lines, with patch releases arriving together across branches. The one substantive move is cross-project search reaching GA on Serverless, which links projects and queries them from one Discover or ES|QL session.

◆ Where it's heading

Serverless is where the feature work shows up: cross-project search and Azure Private Link both landed there in about a month. The self-managed lines are getting steady patch trains, which keeps 8.19 viable as a long-lived branch.

◆ Prediction

Expect further Serverless parity with self-managed cluster features, and continued patch trains across branches. The patch notes shown here do not support a more specific call.
