Simple Realtime Server, an open-source live streaming and WebRTC media server.
SRS now runs three release lines at once and publishes A/B CPU benchmarks with each build.

◆Current state
SRS, the open-source media streaming server, cut v6.0-r3, v7.0-a4 and v8.0-d3 within two minutes on 31 October. Each release now carries an A/B CPU benchmark across 16 delivery scenarios: 6.0-r3 trims 4-6% CPU on RTMP, HTTP-FLV and HTTP-TS, while both 7.0-a4 and 8.0-d3 show RTSP delivery using about 30% more CPU than the prior build. Release commits are co-authored with Claude.
◆Where it's heading
Release engineering is becoming the product's visible discipline: stable, alpha and dev lines ship together with measured performance deltas rather than feature notes. The 7.0 line has moved from dev snapshots into alphas, and 8.0 now takes the dev-snapshot slot.
◆Prediction
The shared RTSP regression in 7.0-a4 and 8.0-d3 is the obvious thing for the next alpha and dev builds to address, given the benchmarks now flag it on every release.
