Roundcube
Roundcube is shipping matched security pairs across 1.7 and 1.6 LTS, roughly monthly.
A side-by-side editorial comparison of Salesmsg and NanoMQ — release velocity, themes, recent moves, and the top alternatives to consider.
Salesmsg keeps shipping AI agents that close the loop without a human touching the thread.
Weekly posts alternate between monthly roundups and single-feature launches, and the AI agent is the through-line. The Booking Agent runs a full scheduling flow over SMS into HubSpot including reschedules and cancellations; the Unified Agent consolidates agent building into one place with conversational setup and live testing before launch. Around that, the calling side has grown real infrastructure — Smart Call Flows with routing actions, business hours, a custom IVR, and concurrent incoming call handling. Reviews arrived in late July as a new module rather than an extension of an existing one.
An edge MQTT broker hardening for vehicles — and dropping the old embedded arches to do it.
NanoMQ closed out the 0.24 line and moved to 0.25 over roughly five months, shipping through a string of pre-releases before 0.25.3 became the first official 0.25 build. The work splits between memory-safety hardening — fuzzing via OSS-Fuzz and ClusterFuzz is now routine after the maintainer noted production use in robotics and vehicles — and protocol-layer restructuring, with QoS acknowledgement handling moved out of the transport layer and configuration reloading rebuilt lock-free. Release notes are candid to a fault: the maintainer publishes AI-drafted changelogs with attribution and openly says he hasn't made up his mind about the SipHash change.

Two expansions are running at once. The first is depth: the agent is moving from replying to executing, taking actions in Salesforce and HubSpot that previously required a rep, with MCP tools letting the same account be driven from an external AI client. The second is breadth: reputation collection is a different business from conversational messaging, and shipping it as a branded review page with routing to public platforms puts Salesmsg into territory occupied by local-business reputation tools. Credit tracking per workflow, agent and broadcast suggests automated volume is now large enough that customers need to see where spend goes.
Expect agent actions to keep extending into whatever the connected CRM supports, and the per-automation credit reporting to harden into spend controls or limits rather than reporting alone.

The project is trading breadth of hardware support for depth of correctness. 0.25.5 drops official MIPS and ARMel binaries because the build toolchain and MsQuic dependency moved on, while the same release adds hazard-pointer reclamation for hot config reload — a broker chasing safety-critical deployments rather than the widest possible router install base. Bridging is the other consistent thread: nng_bridge, then a nolocal parameter for bridge clients, then the earlier anti-loop work.
Expect the 0.25 line to keep tightening QoS and session persistence, and a decision on whether SipHash client ID hashing stays given its CPU cost. Whether dropped architectures return through community builds is not addressed in these entries.
