NanoMQ vs Pixelfed: at a glance
What is NanoMQ?
A protocol-layer correctness pass, delivered largely by first-time contributors
0.25.6 is a bug-fix release the maintainer recommends to every user on an earlier tag, and its weight sits in NanoNNG rather than the broker: unsuccessful CONNACK negotiation is now rejected, Session Expiry Interval is accepted in CONNACK, pipes closed during the unlocked auth window are no longer registered, receive pipes unlink on session handoff, and a strict property checker guards against malformed input. Two potential security issues are patched, SCRAM handling hardened, and a workaround added for an NNG TLS idle bug. Four of the contributors are making their first commit to the project.
What is Pixelfed?
Pixelfed 0.15.2 ships the PHP RCE patches and turns cached timelines on for everyone.
Pixelfed v0.15.2 is an urgent security update: Docker images pick up the patched PHP for this month's two remote code execution CVEs and are rebuilt with updated CAs after the eMudhra compromise. It also makes cached timelines the default, removing two experimental flags, and bundles timeline and WebFinger fixes.

NanoMQ
6.3COMMS
A protocol-layer correctness pass, delivered largely by first-time contributors
◆ Current state
0.25.6 is a bug-fix release the maintainer recommends to every user on an earlier tag, and its weight sits in NanoNNG rather than the broker: unsuccessful CONNACK negotiation is now rejected, Session Expiry Interval is accepted in CONNACK, pipes closed during the unlocked auth window are no longer registered, receive pipes unlink on session handoff, and a strict property checker guards against malformed input. Two potential security issues are patched, SCRAM handling hardened, and a workaround added for an NNG TLS idle bug. Four of the contributors are making their first commit to the project.
◆ Where it's heading
The hardening campaign that began with fuzzing on the 0.24 line has moved up into MQTT protocol conformance — this release is dense with spec-edge handling and lifecycle races rather than crashes. The more interesting shift is social: after 0.25.5 traded architecture breadth for correctness depth, the protocol layer is now attracting outside contributors, with four newcomers landing fixes in NanoNNG in a single release. That is a different growth mode than the maintainer-driven cadence of the 0.24 line.
◆ Prediction
The 0.25 line looks set to continue on protocol conformance and session lifecycle correctness rather than new features. The SipHash client ID hashing question the maintainer raised in 0.25.2 is still open in these entries, with no resolution either way.
Pixelfed
5.0COMMS
Pixelfed 0.15.2 ships the PHP RCE patches and turns cached timelines on for everyone.
◆ Current state
Pixelfed v0.15.2 is an urgent security update: Docker images pick up the patched PHP for this month's two remote code execution CVEs and are rebuilt with updated CAs after the eMudhra compromise. It also makes cached timelines the default, removing two experimental flags, and bundles timeline and WebFinger fixes.
◆ Where it's heading
Pixelfed has moved quickly through 0.14.5 and 0.15 with federation fixes and new APIs, and now an upstream security patch. The notes say heavy refactoring will continue toward a Nuxt-based web UI, so the near term is more churn in the front end.
◆ Prediction
Expect more 0.15.x patches for regressions from the refactor, with the Nuxt web UI as the next visible milestone.
