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 Harbor?

Harbor 2.16 RC1 brings official arm64 builds, custom project roles and smarter proxy caching.

Harbor spent September and October on security patch candidates and rolling back defaults that broke webhooks and legacy signer pulls. The first 2.16.0 candidate is the first feature release in that window. It adds full amd64 and arm64 builds, custom project roles in the UI, proxy-cache repository filters and referrer API proxying, and member audit events.

Apache Airflow vs Harbor: editorial side-by-side

Apache Airflow

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.

Harbor

5.0

Harbor 2.16 RC1 brings official arm64 builds, custom project roles and smarter proxy caching.

◆ Current state

Harbor spent September and October on security patch candidates and rolling back defaults that broke webhooks and legacy signer pulls. The first 2.16.0 candidate is the first feature release in that window. It adds full amd64 and arm64 builds, custom project roles in the UI, proxy-cache repository filters and referrer API proxying, and member audit events.

◆ Where it's heading

The 2.16 line shifts Harbor from patching toward enterprise registry features: finer RBAC, deeper audit trails, and a proxy cache that handles OCI referrers such as signatures and SBOMs. Multi-arch builds make Harbor a straightforward fit for arm64 clusters. Security fixes keep landing alongside, so the 2.14 and 2.15 patch lines will likely continue.

◆ Prediction

Expect further 2.16.0 release candidates before GA, plus more 2.14.x and 2.15.x patch tags. Whether custom roles get a matching API-level story is not yet clear from these notes.
