What is Apache Airflow?

Airflow 3.4 reaches its first release candidate, a week after the 10-20 provider wave.

Airflow published constraints for 3.4.0rc1 on Oct 28, which means core 3.4 has moved from beta to release candidate. The surrounding activity is the 2026-10-20 provider batch (Snowflake 6.20, SMTP 3.2, OpenSearch 1.15, OpenAI 2.2, Standard 1.21 and others), all published without release notes, plus a TypeScript SDK 1.0.0-beta1.

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.

Apache Airflow vs Apereo CAS: editorial side-by-side

5.0

Airflow 3.4 reaches its first release candidate, a week after the 10-20 provider wave.

◆ Current state

Airflow published constraints for 3.4.0rc1 on Oct 28, which means core 3.4 has moved from beta to release candidate. The surrounding activity is the 2026-10-20 provider batch (Snowflake 6.20, SMTP 3.2, OpenSearch 1.15, OpenAI 2.2, Standard 1.21 and others), all published without release notes, plus a TypeScript SDK 1.0.0-beta1.

◆ Where it's heading

Core 3.4 is following the usual beta-to-RC path while providers ship on their own batch schedule. The TypeScript SDK beta and the common-ai provider suggest Airflow is widening who can author tasks, though the feed shows tags rather than feature notes.

◆ Prediction

Expect further 3.4.0 release candidates and then a 3.4.0 final within a few weeks; the entries don't show which features anchor it.

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.
