3CX lands V20 Update 9 — redesigned web client and AI assistants in the PBX
A side-by-side editorial comparison of BigBlueButton and Restream — release velocity, themes, recent moves, and the top alternatives to consider.
BigBlueButton's 4.0 beta defaults to a Unified layout and ships a WASM audio processor.
BigBlueButton is running two parallel tracks: aggressive maintenance on the 3.0 line (six security-and-improvement releases between January and March, with LiveKit audio stabilization the recurring theme) and a 4.0 beta cycle that just hit beta.3 with substantial UX work. v4.0.0-beta.3 makes the Unified layout the default, adds a WASM-based audio processor on the mic stream, introduces user search, a 3-state presenter lock policy, pinned moderator messages, a viewer 'Request to Become Presenter' flow, and Ubuntu 24.04 support.
Restream opens an MCP server so AI assistants can run live streams in plain language.
Restream is shipping at a high weekly cadence across its three surfaces: multistreaming (new destinations like Patreon and embedded web players), clip automation (autoposting by virality score, reusable Editor templates), and analytics (a public API plus shareable reports). The standout move is a Model Context Protocol server that lets Claude, ChatGPT, or Cursor manage streams, destinations, and post-stream analytics through natural language.

BBB is preparing for the 4.0 line as the long-term successor to 3.0. The Unified layout (introduced opt-in in 3.0.19 back in January) is becoming the default; audio infrastructure is being modernized via WASM. The pattern of security patches every two to four weeks on 3.0 signals strong institutional-deployment support discipline. Beta cadence on 4.0 suggests GA is still some months out.
Expect a few more 4.0 beta iterations before release candidates, with feature work converging toward GA in Q3 2026. The 3.0 line will continue to receive security-focused maintenance — institutional users (universities, training orgs) tend to lag on majors, so the dual-track will continue past 4.0 GA.

The standout move is a Model Context Protocol server that lets Claude, ChatGPT, or Cursor manage streams, destinations, and post-stream analytics through natural language.
Restream is turning its multistream studio into something both automation-heavy and AI-operable. AI is showing up as a control layer (the MCP server, AI-generated titles and descriptions) and as an automation layer (autoposted clips, scheduled events). The destination list keeps widening while the clipping and analytics tooling gets deeper, suggesting a platform that wants to run more of the broadcast lifecycle without manual touch.
Restream has signaled MCP tools for Studio, Clips, and uploads plus one-click Claude and ChatGPT apps, so expect the assistant-driven control surface to expand from stream management into live production. Analytics and clip automation are the likeliest areas for the next incremental releases.
