What is PeerJS?

PeerJS keeps publishing release candidates that restate the same two fixes.

Every entry in PeerJS's feed is a release candidate, and each one repeats the bug list of the one before it — the unreliable close event and the data channel ordering fix appear in all four, spanning fourteen months. The genuinely new content per release is thin: a CSP fix removing the need for unsafe-eval, Blob support inside nested objects, and dependency updates. The most recent publication is from April 2024.

What is 3CX?

3CX is rebuilding the PBX around MCP and a dedicated AI server, then letting admins self-serve the rest.

The V20 line is where the product is changing: Update 10 in alpha brings MCP support, a dedicated AI Server for deploying AI infrastructure, and more administrative control, while Update 9 already ships email delivery of AI agent call details, summaries, and transcripts. Around that core, the surfaces are being tidied — the Windows Softphone V5.7 migrates extensions and accounts to the desktop app in one click, and the customer portal now lets subscribers downgrade a self-managed edition or remove hosting without going through support. Routine IP phone firmware updates and a summer support-hours notice fill out the rest of the feed.

0.0

PeerJS keeps publishing release candidates that restate the same two fixes.

◆ Current state

Every entry in PeerJS's feed is a release candidate, and each one repeats the bug list of the one before it — the unreliable close event and the data channel ordering fix appear in all four, spanning fourteen months. The genuinely new content per release is thin: a CSP fix removing the need for unsafe-eval, Blob support inside nested objects, and dependency updates. The most recent publication is from April 2024.

◆ Where it's heading

The changelog reads as a project maintained rather than developed, and one that never quite finishes a release cycle — candidates accumulate, notes carry forward, and stable releases do not appear in this feed. For a WebRTC wrapper this is a specific kind of risk: the browser layer underneath moves regardless, and the fixes that do land here are reactions to it, such as dropping unsafe-eval so the library survives strict Content Security Policies.

◆ Prediction

There is no signal in these entries about what comes next, and no publication in roughly two years; the honest read is that the release cadence has stopped rather than that a particular change is pending.

3CX is rebuilding the PBX around MCP and a dedicated AI server, then letting admins self-serve the rest.

◆ Current state

The V20 line is where the product is changing: Update 10 in alpha brings MCP support, a dedicated AI Server for deploying AI infrastructure, and more administrative control, while Update 9 already ships email delivery of AI agent call details, summaries, and transcripts. Around that core, the surfaces are being tidied — the Windows Softphone V5.7 migrates extensions and accounts to the desktop app in one click, and the customer portal now lets subscribers downgrade a self-managed edition or remove hosting without going through support. Routine IP phone firmware updates and a summer support-hours notice fill out the rest of the feed.

◆ Where it's heading

3CX is treating AI as infrastructure a customer runs rather than a service it resells: a separate AI Server to deploy and manage, knowledge sources you prepare yourself as Markdown, and MCP as the interface for connecting outside assistants. That fits the self-hosted, admin-controlled identity the product has always sold on, and it is the opposite of the hosted-only approach most of the unified-communications field is taking. The portal changes point the same way — the subscription mechanics that used to require a conversation are becoming self-service, which is what a vendor does when it wants administrators, not account managers, driving the relationship.

◆ Prediction

Expect Update 10 to move from alpha to general availability with the AI Server as its headline, and expect the MCP surface to grow from connecting assistants into exposing call data and agent actions as tools other systems can call.
