What is NanoMQ?

An edge MQTT broker hardening for vehicles — and dropping the old embedded arches to do it.

NanoMQ closed out the 0.24 line and moved to 0.25 over roughly five months, shipping through a string of pre-releases before 0.25.3 became the first official 0.25 build. The work splits between memory-safety hardening — fuzzing via OSS-Fuzz and ClusterFuzz is now routine after the maintainer noted production use in robotics and vehicles — and protocol-layer restructuring, with QoS acknowledgement handling moved out of the transport layer and configuration reloading rebuilt lock-free. Release notes are candid to a fault: the maintainer publishes AI-drafted changelogs with attribution and openly says he hasn't made up his mind about the SipHash change.

What is Proton Bridge?

Proton Bridge has re-accelerated, with a quality-and-security pass across error UX, FIDO2, and Go modernization.

After a long pause through mid-2025, Proton Bridge resumed steady releases in early 2026 and has now shipped four versions in five months (v3.22 through v3.25). The work is uniformly internal: friendlier error messages, a Go 1.26 toolchain bump, FIDO2 path fixes, IMAP robustness, certificate-chain validation tightening, and the March 2026 security-patch sweep. Visible user-facing additions are limited to MacOS26 icon support and quality-of-life polish.

NanoMQ vs Proton Bridge: editorial side-by-side

NanoMQ

6.3

An edge MQTT broker hardening for vehicles — and dropping the old embedded arches to do it.

◆ Current state

NanoMQ closed out the 0.24 line and moved to 0.25 over roughly five months, shipping through a string of pre-releases before 0.25.3 became the first official 0.25 build. The work splits between memory-safety hardening — fuzzing via OSS-Fuzz and ClusterFuzz is now routine after the maintainer noted production use in robotics and vehicles — and protocol-layer restructuring, with QoS acknowledgement handling moved out of the transport layer and configuration reloading rebuilt lock-free. Release notes are candid to a fault: the maintainer publishes AI-drafted changelogs with attribution and openly says he hasn't made up his mind about the SipHash change.

◆ Where it's heading

The project is trading breadth of hardware support for depth of correctness. 0.25.5 drops official MIPS and ARMel binaries because the build toolchain and MsQuic dependency moved on, while the same release adds hazard-pointer reclamation for hot config reload — a broker chasing safety-critical deployments rather than the widest possible router install base. Bridging is the other consistent thread: nng_bridge, then a nolocal parameter for bridge clients, then the earlier anti-loop work.

◆ Prediction

Expect the 0.25 line to keep tightening QoS and session persistence, and a decision on whether SipHash client ID hashing stays given its CPU cost. Whether dropped architectures return through community builds is not addressed in these entries.

P2.5

Proton Bridge has re-accelerated, with a quality-and-security pass across error UX, FIDO2, and Go modernization.

◆ Current state

After a long pause through mid-2025, Proton Bridge resumed steady releases in early 2026 and has now shipped four versions in five months (v3.22 through v3.25). The work is uniformly internal: friendlier error messages, a Go 1.26 toolchain bump, FIDO2 path fixes, IMAP robustness, certificate-chain validation tightening, and the March 2026 security-patch sweep. Visible user-facing additions are limited to MacOS26 icon support and quality-of-life polish.

◆ Where it's heading

The product is in active maintenance mode rather than feature expansion. Investment is going into making the local sync layer more robust — mailbox conflict resolution, IMAP IDLE kill switch, vault retries on Linux — and the auth surface harder, with FIDO2 polish and TLS pin scoping. The arc reads as catching up on technical debt and shoring up security posture after a quieter year, not reshaping the product.

◆ Prediction

Expect the v3.2x cadence to continue with similar bug-fix and security flavor: more Go toolchain work, incremental IMAP edge-case handling, and continued error-UX tightening. The release notes do not surface anything that would hint at a v4 reshape or a meaningful new capability in the near term.
