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 Superhuman?
Superhuman rebuilt its mobile apps and wired every inbox into AI assistants — the email client is becoming a suite.
Superhuman has evolved from a keyboard-shortcut email client into an AI-native communication platform covering email, calendar, and AI drafting agents — all gated on Business/Enterprise tiers. The mobile apps, long a weak point relative to desktop, received their first major overhaul in years with a redesigned navigation model and native iOS/Android aesthetics. MCP support with multi-account access is live, letting AI assistants like Claude and ChatGPT operate across all connected inboxes simultaneously. Calendar coverage now spans desktop, Android, and iOS with room booking and multi-day views.

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.
Superhuman
6.3COMMS
Superhuman rebuilt its mobile apps and wired every inbox into AI assistants — the email client is becoming a suite.
◆ Current state
Superhuman has evolved from a keyboard-shortcut email client into an AI-native communication platform covering email, calendar, and AI drafting agents — all gated on Business/Enterprise tiers. The mobile apps, long a weak point relative to desktop, received their first major overhaul in years with a redesigned navigation model and native iOS/Android aesthetics. MCP support with multi-account access is live, letting AI assistants like Claude and ChatGPT operate across all connected inboxes simultaneously. Calendar coverage now spans desktop, Android, and iOS with room booking and multi-day views.
◆ Where it's heading
Superhuman is building toward a unified communication suite — the rebranded 'Superhuman Mail' name explicitly anticipates Mail, Docs, and Go as sibling products. The heavy investment in calendar (rooms, Android, multi-day iOS views) signals calendar parity with email as a near-term priority. AI drafting is moving toward full automation: Auto Drafts 2.0 already completes 60% of replies without editing, and the team has announced a voice mode and a rewritten email engine as the next milestones.
◆ Prediction
Voice mode and a rewritten email engine are both on the stated roadmap. The most likely next shipping moment is deeper tool integrations for Auto Drafts — Slack and meeting-notes context were specifically teased — which would close the gap between drafting and the rest of a user's work context.
