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 Certbot?

Certbot is consolidating its plugin architecture and quietly expanding into IP address certificate support.

Certbot is in a steady maintenance and architectural consolidation phase. The nginx and apache plugins have been moved into the core certbot package as private modules (certbot-apache and certbot-nginx now exist primarily to register the plugin), the OCSP module is deprecated, and pyOpenSSL dependencies are being systematically removed in favor of the cryptography library. Version 5.8.0 bumped the cryptography floor to >=47.0.0 and fixed a bug where removed domains were omitted from renewal confirmation prompts — a correctness issue for users who remove SANs from existing certificates.

Apache Airflow vs Certbot: editorial side-by-side

A
Apache Airflow
INFRA · APIS
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.

2.5

Certbot is consolidating its plugin architecture and quietly expanding into IP address certificate support.

◆ Current state

Certbot is in a steady maintenance and architectural consolidation phase. The nginx and apache plugins have been moved into the core certbot package as private modules (certbot-apache and certbot-nginx now exist primarily to register the plugin), the OCSP module is deprecated, and pyOpenSSL dependencies are being systematically removed in favor of the cryptography library. Version 5.8.0 bumped the cryptography floor to >=47.0.0 and fixed a bug where removed domains were omitted from renewal confirmation prompts — a correctness issue for users who remove SANs from existing certificates.

◆ Where it's heading

The architectural direction is a leaner, more self-contained core with fewer external dependencies. The IP address issuance capability added across the 5.3-5.4 cycle reflects Let's Encrypt's expanding IP certificate program — Certbot is tracking the CA's capabilities rather than driving its own feature agenda. The pyOpenSSL removal, when complete, will eliminate a long-standing external dependency that complicated builds and tested certification paths.

◆ Prediction

pyOpenSSL removal will complete in a future major release. IP address certificate workflows will mature as Let's Encrypt's IP cert program broadens. The certbot-nginx/certbot-apache split (now thin wrappers over the core package) may eventually collapse entirely.
