A side-by-side editorial comparison of Element X Android and NanoMQ — release velocity, themes, recent moves, and the top alternatives to consider.
Element X Android turns on multi-select forwarding and better search in v26.11.0.
Element X Android v26.11.0 enables multi-select forwarding by default, renders media captions and updated display names in the new timeline renderer, and keeps previous results visible while searching with the 3-month limit shown. It also fixes voice-message playback sync and a crash on logout. It follows v26.10.0's multi-account and global search launch.
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.

It also fixes voice-message playback sync and a crash on logout. It follows v26.10.0's multi-account and global search launch.
The app is moving its new timeline renderer toward default and polishing the October features: forwarding, search and multi-account. Releases arrive every one to three weeks.
Expect the new timeline renderer to become the default within the next one or two releases.
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.
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.
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.
