Stalwart
Stalwart is shipping email's next-generation auth stack while the specs are still in draft.
A side-by-side editorial comparison of Beeper and VerneMQ — release velocity, themes, recent moves, and the top alternatives to consider.
Beeper stopped aggregating apps and started merging the people inside them.
The bridge count keeps climbing, with LINE the most recent addition, but the more consequential work is identity-level. Merge Chats collapses conversations with the same person across multiple networks into a single thread. Around that sits a long run of parity work — group chat creation, delete chat, disappearing messages, message requests — closing the gaps that forced users back into native clients.
VerneMQ's 2.2.0 collects a year of cluster and connection fixes into one release.
VerneMQ ships infrequently — the six most recent releases span February 2025 to August 2026 — and 2.2.0 on 9 August gathers roughly a year of accumulated work. Its contents are broker internals: a socket-accounting fix for rapid connect/disconnect churn, MQTT v5 property handling in the Lua auth cache, ETS-mirrored event subscriptions in the SWC metadata store, parallelised inter-node readiness checks, and anonymous-override extended to WebSocket listeners. The 2.1.3 release candidate from April was folded in and the version renumbered.

Two tracks run in parallel. Parity work is making Beeper safe to use as the only client, and for the major networks it is close to finished. On top of that, the product is starting to add things no native app can do: cross-network chat merging, in-chat AI models, a unified requests folder. The public call for third-party bridges suggests network coverage is increasingly a community responsibility rather than an in-house roadmap item.
With conversations merged across networks, unified contacts and cross-network search are the natural follow-ons — the organizing primitive shifts from the chat to the person.

Work concentrates on cluster behaviour and connection churn — the failure modes large MQTT fleets actually hit — rather than on protocol surface. Defaults are being revisited alongside the fixes: the retain-expiry check is now off by default and SWC initial sync is set to off, both choices that favour predictable behaviour on busy clusters over automatic housekeeping. Development stays maintainer-paced, with dependency bumps making up a visible share of each changelog, and the commercial EULA on binary packages continues to sit alongside the open source.
The next release is most likely another long-cycle collection of cluster and listener fixes rather than a feature line. Nothing in these entries points to a 3.0 direction.
