What is VerneMQ?
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.
What is Respond.io?
Respond.io upgraded its AI Agents to GPT-5.6 and added TikTok Business Messaging for US accounts.
Respond.io is shipping across three tracks simultaneously: AI Agent improvements (GPT-5.6 model upgrade, pre-publish instruction review), channel expansion (TikTok Business Messaging for US, Microsoft 365/Outlook email), and workflow automation (missed call auto-follow-up, Google Calendar integration). The status persistence fix — keeping agents online as long as the tab is open — addresses a real reliability concern for teams that rely on online/offline presence for routing.

VerneMQ
2.5COMMS
VerneMQ's 2.2.0 collects a year of cluster and connection fixes into one release.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
Respond.io
7.5COMMSSUPPORT
Respond.io upgraded its AI Agents to GPT-5.6 and added TikTok Business Messaging for US accounts.
◆ Current state
Respond.io is shipping across three tracks simultaneously: AI Agent improvements (GPT-5.6 model upgrade, pre-publish instruction review), channel expansion (TikTok Business Messaging for US, Microsoft 365/Outlook email), and workflow automation (missed call auto-follow-up, Google Calendar integration). The status persistence fix — keeping agents online as long as the tab is open — addresses a real reliability concern for teams that rely on online/offline presence for routing.
◆ Where it's heading
The product is converging on a model where AI Agents handle routine conversations while human agents handle escalations, with channels increasingly auto-enrolled (missed calls become conversations, calendar events surface in the inbox). The channel expansion pace (TikTok, Microsoft 365, Google Calendar within weeks) suggests a deliberate push to cover every channel a business customer might use.
◆ Prediction
Voice channel integration — handling inbound calls with AI Agents rather than just converting missed calls into follow-ups — would complete the omnichannel picture respond.io is assembling.
