VerneMQ
A slow, careful MQTT broker that spent two years landing one breaking storage change.
A side-by-side editorial comparison of Apache RocketMQ and Zoho Mail — release velocity, themes, recent moves, and the top alternatives to consider.
RocketMQ built a stripped-down subscription mode for AI workloads — then went quiet for four months.
The 5.x line has spent this window replacing storage internals and tightening the security model. RocksDB moved from an experimental ConsumeQueue index to backing Pop consumption, timer messages, transaction messages and indexes; ACL 1.0 was removed outright in favour of ACL 2.0; priority messages arrived in 5.4.0. The most recent release, 5.5.0 in April, introduced Lite Mode — a lightweight subscription mechanism with its own message processor, long-polling service and protocol support, explicitly framed for AI scenarios. Nothing has shipped since.
Zoho Mail is annexing the workday around the inbox: web tabs, tasks, and an MCP endpoint.
Zoho Mail's feed is mostly explainer and positioning content, but the product moves inside it all point one direction: the inbox as a container for the rest of the workday. Web Tabs pins third-party sites beside the mailbox, Zoho ToDo carries tasks, and an MCP endpoint opens the mailbox to agents. The enterprise layer around it — admin console, journaling, admin reports — is being documented and rounded out rather than rebuilt.

Nothing has shipped since.
Two forces are shaping the project. Underneath, the storage layer is converging on RocksDB across every subsystem that used to have its own file format, which is a multi-release migration with a stated plan rather than an opportunistic change. Above it, Lite Mode is a bid to be the broker for many small, resource-light consumers rather than a few heavyweight ones — the shape AI agent and inference workloads take. The four-month gap since 5.5.0 makes it hard to tell whether that bid is being pressed or parked.
Lite Mode arrived without client-side adoption guidance, so the obvious next step is client and proxy support to make it usable end-to-end — but with no release since April, the entries do not support a confident read on timing.
Zoho Mail's feed is mostly explainer and positioning content, but the product moves inside it all point one direction: the inbox as a container for the rest of the workday.

The enterprise layer around it — admin console, journaling, admin reports — is being documented and rounded out rather than rebuilt.
The arc is consolidation rather than depth: instead of making email itself better, Zoho is absorbing the surfaces users leave the mailbox for. Two access paths are advancing in parallel — a human one through Web Tabs and ToDo, and a programmatic one through MCP and Client Scripting. The compliance and admin material signals who this is aimed at, and Microsoft's EWS retirement is being worked as a migration opening for displaced Exchange Online tenants.
Expect both paths to extend — more embeddable surfaces inside the mail UI, and more of the mailbox reachable through MCP and Client Scripting. The entries show no pricing or packaging changes, so which of these land in the paid enterprise tiers is unclear from this window.
