What is NanoMQ?
NanoMQ follows its hardening run by moving onto Zephyr microcontrollers.
NanoMQ 0.25.7, published on 21 October and described as a beta, runs on the Zephyr RTOS after platform-layer work on memory allocation for microkernel environments. It also pushes the multi-tenant mountpoint logic down into the transport layer, gives each bridge its own cache with REST control, lets operators kick clients by ID over the API, and supports PKCS#11 hardware keys with certificate-to-username mapping. 0.25.6 in August had been a protocol-conformance and auth-race fix release.
What is Subsplash?
Subsplash turns its Dashboard Home into one view across every church product
Subsplash runs giving, media, people and workflow tools for churches. Late September brought notes on People profiles and Workflow cards and gift totals in Giving; October added multi-select actions on People. On November 4 the Dashboard Home page expanded from app and media analytics to live cards for People, Giving, Events, Groups, Workflows and Forms, each with trend lines and quick actions.

NanoMQ
2.5COMMS
NanoMQ follows its hardening run by moving onto Zephyr microcontrollers.
◆ Current state
NanoMQ 0.25.7, published on 21 October and described as a beta, runs on the Zephyr RTOS after platform-layer work on memory allocation for microkernel environments. It also pushes the multi-tenant mountpoint logic down into the transport layer, gives each bridge its own cache with REST control, lets operators kick clients by ID over the API, and supports PKCS#11 hardware keys with certificate-to-username mapping. 0.25.6 in August had been a protocol-conformance and auth-race fix release.
◆ Where it's heading
0.25.5 dropped MIPS and ARMel binaries to concentrate on correctness, and 0.25.6 spent that effort on MQTT conformance. 0.25.7 points the broker at smaller and more locked-down hardware instead: an RTOS target, hardware security modules and per-device certificate identity. That is a move toward embedded, fleet-managed deployments rather than gateway servers.
◆ Prediction
Expect follow-up 0.25.x releases fixing Zephyr-specific issues, since 0.25.7 is labelled a first beta. The SipHash client ID question raised in 0.25.2 still has no resolution in these entries.
Subsplash
5.0COMMS
Subsplash turns its Dashboard Home into one view across every church product
◆ Current state
Subsplash runs giving, media, people and workflow tools for churches. Late September brought notes on People profiles and Workflow cards and gift totals in Giving; October added multi-select actions on People. On November 4 the Dashboard Home page expanded from app and media analytics to live cards for People, Giving, Events, Groups, Workflows and Forms, each with trend lines and quick actions.
◆ Where it's heading
The product is pulling its separate modules into one staff workspace: notes and multi-select made each module more usable, and Home now ties them together. The first-step prompts on Home also show an effort to get churches using products they have not tried.
◆ Prediction
Expect more cross-product actions from Home and further staff-workflow features in People and Workflows.
