What is Snort 3?

Snort 3's release train is almost entirely appid: identifying traffic it can no longer read.

Every release in this window is dominated by two threads. The first is appid, the application identification engine, which keeps gaining ways to classify traffic that encryption has closed off: a QUIC extractor, preferring QUIC appid over SSL, midstream service discovery, SSL detection during midstream, and a fix for detection when the SNI is spoofed. The second is a sustained memory-safety campaign across dce_rpc, dce_smb, and appid, with use-after-frees, leaks, underflows, and out-of-bounds reads closed release after release.

What is Resend?

Resend is turning an email API into something other people build products on.

Two months of releases split cleanly. One half is dashboard housekeeping — template folders, suppression management, Open Graph previews in the editor, Message-ID exposed on webhooks for threading. The other half is platform plumbing: a hosted MCP server, OAuth 2.1 with PKCE, a Claude connector, a Codex marketplace plugin, and automatic revocation of API keys leaked to GitHub.

Snort 3's release train is almost entirely appid: identifying traffic it can no longer read.

◆ Current state

Every release in this window is dominated by two threads. The first is appid, the application identification engine, which keeps gaining ways to classify traffic that encryption has closed off: a QUIC extractor, preferring QUIC appid over SSL, midstream service discovery, SSL detection during midstream, and a fix for detection when the SNI is spoofed. The second is a sustained memory-safety campaign across dce_rpc, dce_smb, and appid, with use-after-frees, leaks, underflows, and out-of-bounds reads closed release after release.

◆ Where it's heading

Snort is adapting an inspection engine built for readable traffic to a network where most of it is not. The investment is in inferring application identity from what remains visible, and in doing so on flows the sensor joined late. Alongside that, output is becoming more machine-consumable, with appid in alert_json, binary flow state dumps, and new DNS counters. The C codebase is being hardened continuously, which suggests fuzzing and sanitizer work running behind the feature stream.

◆ Prediction

QUIC handling has moved from an extractor to an appid preference in consecutive releases while midstream detection keeps widening; extending the same treatment to more encrypted protocols is the clearest continuation these entries support.

Resend is turning an email API into something other people build products on.

◆ Current state

Two months of releases split cleanly. One half is dashboard housekeeping — template folders, suppression management, Open Graph previews in the editor, Message-ID exposed on webhooks for threading. The other half is platform plumbing: a hosted MCP server, OAuth 2.1 with PKCE, a Claude connector, a Codex marketplace plugin, and automatic revocation of API keys leaked to GitHub.

◆ Where it's heading

The center of gravity has moved from features a developer uses to interfaces another product consumes. OAuth is the hinge — with it, third parties can act on a user's Resend account without holding a key, which is the precondition for the connector and plugin distribution Resend is now shipping into Claude, Codex and Cursor. Tracking the 2026-07-28 MCP spec within nine days says they intend to stay current with that surface rather than treat it as a side project.

◆ Prediction

The pattern points to scoped OAuth permissions and a listing surface for third-party Resend apps, plus continued fast-following of MCP spec revisions. Nothing in these entries indicates a pricing or deliverability change.
