What is NGINX?

Mainline and stable now move in lockstep, and almost every move is a CVE.

NGINX is running 1.31.x mainline and 1.30.x stable in parallel, cutting matched pairs of releases minutes apart whenever a security fix lands. Every release in the window is security-driven: buffer overflows in map-with-regex and the rewrite module, memory disclosure in the slice module, use-after-free in SSI and HTTP/3, buffer overreads in charset, SCGI and uWSGI. Feature work is confined to what rides along — a SipHash-based request ID, an $ssl_sigalgs variable.

What is Resend?

Resend is wiring itself into every agent runtime it can reach, and now adding the controls to stop a send.

Most recent entries are about who or what can call Resend rather than about email delivery itself: OAuth 2.1 with PKCE, a remote MCP server tracking the current spec, a Codex plugin, a one-click Claude connector, and support for the Agent Plugins Standard. The email product still gets attention — suppressions, template folders, a compatibility checker in the code editor, and now cancellation of scheduled or queued Broadcasts from the API. Entries are terse one-liners, so the shipping cadence reads faster than the surface area actually changing.

NGINX vs Resend: editorial side-by-side

NGINX
INFRA · APIS
5.0

Mainline and stable now move in lockstep, and almost every move is a CVE.

◆ Current state

NGINX is running 1.31.x mainline and 1.30.x stable in parallel, cutting matched pairs of releases minutes apart whenever a security fix lands. Every release in the window is security-driven: buffer overflows in map-with-regex and the rewrite module, memory disclosure in the slice module, use-after-free in SSI and HTTP/3, buffer overreads in charset, SCGI and uWSGI. Feature work is confined to what rides along — a SipHash-based request ID, an $ssl_sigalgs variable.

◆ Where it's heading

The 1.30.0 stable branch pulled in a substantial feature set from 1.29.x — Early Hints, HTTP/2 to backend, Encrypted ClientHello, sticky upstream sessions, Multipath TCP, HTTP/1.1 keep-alive as the proxy default — and 1.31.0 added HTTP forward proxy and least_time load balancing. Since those, the project has been consolidating: hardening the newer protocol modules, particularly HTTP/2 and HTTP/3, where most of the recent CVEs cluster.

◆ Prediction

Expect the paired mainline/stable security releases to continue at this cadence, with the vulnerability reports staying concentrated in HTTP/2, HTTP/3 and the proxying modules that 1.30 broadened.

6.3

Resend is wiring itself into every agent runtime it can reach, and now adding the controls to stop a send.

◆ Current state

Most recent entries are about who or what can call Resend rather than about email delivery itself: OAuth 2.1 with PKCE, a remote MCP server tracking the current spec, a Codex plugin, a one-click Claude connector, and support for the Agent Plugins Standard. The email product still gets attention — suppressions, template folders, a compatibility checker in the code editor, and now cancellation of scheduled or queued Broadcasts from the API. Entries are terse one-liners, so the shipping cadence reads faster than the surface area actually changing.

◆ Where it's heading

Resend is treating agents as the next class of sending client and building the authorization and discovery plumbing they need before that traffic arrives. The progression is legible: authenticate third parties (OAuth), be callable (MCP), be installable per vendor (Codex, Claude), then be installable by standard. The Cancel Broadcast API is the first sign of the next phase — once non-human callers can schedule sends, the ability to revoke one programmatically stops being a convenience.

◆ Prediction

Authorization and discovery are covered and reversibility has now started; the remaining gap is what an agent is permitted to send in the first place, so scoped per-agent sending limits or approval gates before dispatch are the natural next piece.
