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.

What is Redocly?

Redocly's reunite.agent gets per-duty cron schedules, rules and source repos.

Redocly shipped three Reunite releases and a config release on Oct 28. The feedback and discovery duties in reunite.agent can now each run on their own UTC cron trigger, follow their own rules and read only listed source repositories. SCIM provisioning now accepts identity-provider groups of any size, where pushes over 1,000 members used to fail. @redocly/config 0.69.0 also adds per-rule impact settings for the experimental diff command.

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.

Redocly's reunite.agent gets per-duty cron schedules, rules and source repos.

◆ Current state

Redocly shipped three Reunite releases and a config release on Oct 28. The feedback and discovery duties in reunite.agent can now each run on their own UTC cron trigger, follow their own rules and read only listed source repositories. SCIM provisioning now accepts identity-provider groups of any size, where pushes over 1,000 members used to fail. @redocly/config 0.69.0 also adds per-rule impact settings for the experimental diff command.

◆ Where it's heading

Two threads run together: an agent inside Reunite that does recurring docs work (feedback and discovery) and is gaining scheduling and scoping controls, and enterprise plumbing such as SCIM scale, Git token rotation and permission fixes. Last week's configurable docs MCP server points the same way, with Redocly adding AI surfaces and making them configurable in redocly.yaml.

◆ Prediction

Expect more reunite.agent duty types or options in @redocly/config, and the experimental diff command moving toward a documented API-change check.
