Apache Druid
Druid 38 drops Java 17, recommends Java 25 and took longer to arrive than its predecessors
A side-by-side editorial comparison of Algolia and Apereo CAS — release velocity, themes, recent moves, and the top alternatives to consider.
Algolia's Agent Studio opens to outside agents and starts grading its own before they ship
October put Agent Studio in front. The A2A protocol lets external agents and orchestration frameworks discover and call Studio agents through standardized agent cards, and automated evaluations score an agent on relevance, faithfulness and tone before deployment, using test cases generated from the customer's search index. AI Assist gained a No results agent that diagnoses zero-result searches, and automated suggestions now recommend Dynamic Re-Ranking, Personalization and NeuralSearch from performance data. On the commerce side, retail media network orchestration reached general availability for Elevate Ecommerce customers.
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.

Two tracks are running together. Agent Studio is collecting what a production agent platform needs, an interoperability standard and a pre-deployment test loop, while AI Assist and automated suggestions turn the dashboard into something that tells merchandisers what to change. Retail media GA and the combined-signal setting in Dynamic Re-Ranking show the commerce core still shipping beside the agent work rather than giving way to it.
Automated suggestions is described as an initial release covering three features, so more features joining it is the safest call. Evaluations also let teams compare runs, which points toward using scores to gate a configuration change, though the entries do not say that is planned.

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.
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.
