What is FusionPBX?

The release feed stops in 2018, so nothing here describes the current product

Every visible entry predates 2019. The newest is 4.4.1, a minor bug-fix release covering call centre login, device password propagation and call detail record naming. Below it sit 4.4.0 with user change logs, call recording management, QR-code provisioning and added translations, and two 4.2.x releases focused on bug fixes and SQL injection hardening in LUA scripts.

What is SRS?

SRS opens a 7.0 line built on a Go proxy tier, and drops features it no longer wants to carry.

SRS shipped the stable 6.0 line's first release on 12 August and, three hours later, the first development build of 7.0. The 6.0 line is now in pure maintenance — the r1 changelog is seven merges of DVR, WebRTC and edge fixes. Everything new is in 7.0-d0: RTSP playback, RTMPS, IPv6 across every protocol, HEVC in both directions between RTMP and WebRTC, and HLS fMP4 segments for HEVC and LL-HLS.

◆ Current state

Every visible entry predates 2019. The newest is 4.4.1, a minor bug-fix release covering call centre login, device password propagation and call detail record naming. Below it sit 4.4.0 with user change logs, call recording management, QR-code provisioning and added translations, and two 4.2.x releases focused on bug fixes and SQL injection hardening in LUA scripts.

◆ Where it's heading

What the archive shows is a project that treated security hardening as release-worthy in its own right and steadily broadened administrative tooling around FreeSWITCH. What it cannot show is anything about the last several years — the feed has been silent since 2018, so no current direction is observable.

◆ Prediction

There is not enough recent data to predict a next move. Until this feed carries releases again, the product's current state is unreadable from here.

SRS opens a 7.0 line built on a Go proxy tier, and drops features it no longer wants to carry.

◆ Current state

SRS shipped the stable 6.0 line's first release on 12 August and, three hours later, the first development build of 7.0. The 6.0 line is now in pure maintenance — the r1 changelog is seven merges of DVR, WebRTC and edge fixes. Everything new is in 7.0-d0: RTSP playback, RTMPS, IPv6 across every protocol, HEVC in both directions between RTMP and WebRTC, and HLS fMP4 segments for HEVC and LL-HLS.

◆ Where it's heading

The project is trading breadth of legacy surface for a narrower, better-covered core. 7.0-d0 removes the embedded GB28181 SIP server, multi-threading, Cygwin, and most configuration hot reload, while introducing a Go proxy server and origin-cluster architecture alongside the C++ media core. Protocol coverage keeps generalizing — each release makes a codec or an address family a property of the server rather than of one delivery path.

◆ Prediction

Expect the 7.0 line to run a long alpha and beta train the way 6.0 did, with the Go proxy and origin clustering carrying most of the remaining work and 6.0 continuing to receive backported fixes in parallel.
