Apache RocketMQ
RocketMQ built a stripped-down subscription mode for AI workloads — then went quiet for four months.
A side-by-side editorial comparison of Elastic Email and VerneMQ — release velocity, themes, recent moves, and the top alternatives to consider.
A deliverability vendor ships DMARCRadar and lets case studies do the rest of the talking.
Most of this feed is customer proof and category education — two case studies, an explainer on what an email service provider actually does, and an agency-scaling piece. Two entries carry product substance: DMARCRadar, a new DMARC monitoring tool introduced alongside a primer on why domain authentication exists, and a Pipedrive integration that syncs CRM contacts into email lists without CSV round trips.
A slow, careful MQTT broker that spent two years landing one breaking storage change.
VerneMQ is in low-cadence maintenance on the 2.1.x line, with releases spaced months apart and a 2.1.3 release candidate open since April. The work is concentrated in the clustering metadata store (vmq_swc), the MQTT session state machine, and WebSocket listener behaviour — the parts operators actually file bugs against. Commercial binaries remain EULA-gated, so the open-source repo is the product surface and the packages are the business.

Elastic Email is expanding from sending infrastructure into the authentication and reputation layer around it. DMARCRadar is the clearest expression of that, taking a compliance problem senders currently solve with a separate vendor and folding it into the platform that already handles delivery. The integration work points the other way, toward the CRM systems where contact data originates, while the case studies consistently emphasize customer tenure and API-based usage rather than campaign features.
Expect DMARCRadar to gain enforcement guidance that walks senders from monitoring policy toward quarantine and reject, and expect more native CRM connectors following the Pipedrive pattern.

The centre of gravity is correctness in clustered deployments, not new protocol capability. Recent releases keep tightening the same three areas — connection accounting under churn, proxy-header handling behind load balancers, and metadata sync for joining nodes — which reads as a broker being hardened for larger clusters rather than broadened. The RC-heavy release pattern (three RCs before 2.1.0, one open for 2.1.3) suggests a small team leaning on community testing before committing.
2.1.3 ships as a fix-consolidation release absorbing the remaining open PRs, with the retain-expiry default change carried through. Nothing in these entries points to a new protocol or storage direction after that.
