What is RabbitMQ?

RabbitMQ 4.4 moves to Erlang 28 and tightens OpenID Connect checks, with 4.3 still patched.

RabbitMQ shipped 4.4.0 on October 28 with full Erlang 28 support and stricter OpenID Connect discovery validation that can break setups with non-compliant identity providers. The 4.3 line keeps receiving maintenance releases: 4.3.6 in September fixed exchange deletion leaving behind bindings that pointed to it, quorum queue membership reconciliation adding too many replicas, and double-counted message store references in classic queue recovery; 4.3.7 followed in October.

What is Windmill?

Windmill adds workspace roles and AI decision steps as its agent tooling fills out.

Windmill is an open-source workflow and internal-tools platform adding AI and governance features quickly. Mid-September brought a headless Chat SDK for chat-mode flows, per-run tool selection for AI agent steps, origin allowlists for HTTP routes, GitHub CI gating and GitLab git-sync parity. October added an AI decision step, operator builder rights and default Developer and Operator workspace roles.

RabbitMQ vs Windmill: editorial side-by-side

5.0

RabbitMQ 4.4 moves to Erlang 28 and tightens OpenID Connect checks, with 4.3 still patched.

◆ Current state

RabbitMQ shipped 4.4.0 on October 28 with full Erlang 28 support and stricter OpenID Connect discovery validation that can break setups with non-compliant identity providers. The 4.3 line keeps receiving maintenance releases: 4.3.6 in September fixed exchange deletion leaving behind bindings that pointed to it, quorum queue membership reconciliation adding too many replicas, and double-counted message store references in classic queue recovery; 4.3.7 followed in October.

◆ Where it's heading

Feature work has moved to 4.4 while 4.3 absorbs correctness fixes, many in quorum queues and cleanup paths. The stricter OIDC validation in 4.4 continues the security tightening seen in 4.3.5's encrypted management login tokens.

◆ Prediction

Expect 4.4.x patches, likely including fixes for identity providers caught by the stricter OIDC checks, alongside further 4.3.x maintenance.

Windmill adds workspace roles and AI decision steps as its agent tooling fills out.

◆ Current state

Windmill is an open-source workflow and internal-tools platform adding AI and governance features quickly. Mid-September brought a headless Chat SDK for chat-mode flows, per-run tool selection for AI agent steps, origin allowlists for HTTP routes, GitHub CI gating and GitLab git-sync parity. October added an AI decision step, operator builder rights and default Developer and Operator workspace roles.

◆ Where it's heading

Windmill is building AI agents into flows as first-class steps with controls over which tools they can use, while adding the role and access model enterprises need to let more people build. Developer workflow parity across Git hosts continues in parallel.

◆ Prediction

Expect more AI agent controls and role-based permissions; whether the Chat SDK grows into a hosted chat product is unclear.
