What is NGINX?

nginx patched HTTP/3 twice in a month and is trimming old platform code on mainline.

nginx runs a 1.31 mainline and a 1.30 stable line. After 1.31.5 added a native control API, a JSON module and predicate locations in September, the following releases were mostly security: 1.31.6 and 1.30.5 fixed an HTTP/3 buffer overflow (CVE-2026-90439), then 1.31.7 and 1.30.6 fixed five more CVEs including HTTP/3 request body injection. 1.31.8 on October 21 removed the Win32 iocp event module and fixed further HTTP/3 issues.

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.

nginx patched HTTP/3 twice in a month and is trimming old platform code on mainline.

◆ Current state

nginx runs a 1.31 mainline and a 1.30 stable line. After 1.31.5 added a native control API, a JSON module and predicate locations in September, the following releases were mostly security: 1.31.6 and 1.30.5 fixed an HTTP/3 buffer overflow (CVE-2026-90439), then 1.31.7 and 1.30.6 fixed five more CVEs including HTTP/3 request body injection. 1.31.8 on October 21 removed the Win32 iocp event module and fixed further HTTP/3 issues.

◆ Where it's heading

HTTP/3 has needed fixes in each of the last three mainline releases, two of them CVEs. Mainline is adding features and removing legacy code at the same time, while stable gets the CVE backports.

◆ Prediction

More HTTP/3 fixes on both lines are likely; on mainline, follow-up work on the control API and JSON module is the next feature thread to watch.

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.
