What is Apache RocketMQ?

The RocksDB migration reaches native code as the legacy DLedger broker mode is marked for removal

The 5.x line continues to replace storage internals with RocksDB and to retire the mechanisms it supersedes. 5.5.1, the first release since April, swaps the pure-Java ConsumeQueue compaction filter for a native RocksDB CqCompactionFilter behind a cross-platform JNI shim, drops the shaded rocketmq-rocksdb dependency, and deprecates the legacy Broker DLedger mode. Lite Mode, introduced in 5.5.0, received stability work rather than the client-side adoption path it still needs. Alongside this sit fastjson 1.x removal and a long list of Proxy, Pop and Remoting fixes.

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.

Apache RocketMQ vs Superhuman: editorial side-by-side

A2.5

The RocksDB migration reaches native code as the legacy DLedger broker mode is marked for removal

◆ Current state

The 5.x line continues to replace storage internals with RocksDB and to retire the mechanisms it supersedes. 5.5.1, the first release since April, swaps the pure-Java ConsumeQueue compaction filter for a native RocksDB CqCompactionFilter behind a cross-platform JNI shim, drops the shaded rocketmq-rocksdb dependency, and deprecates the legacy Broker DLedger mode. Lite Mode, introduced in 5.5.0, received stability work rather than the client-side adoption path it still needs. Alongside this sit fastjson 1.x removal and a long list of Proxy, Pop and Remoting fixes.

◆ Where it's heading

The storage convergence is now deep enough to cross the JNI boundary — RocksDB is no longer an alternate index but the substrate, and the project is willing to take on native build complexity across platforms to get its performance. In parallel, deprecating legacy Broker DLedger narrows the replication story toward the jRaft controller, cutting a maintenance branch rather than carrying both. Lite Mode remains the open bet: it is being maintained but not yet extended outward to clients.

◆ Prediction

With legacy DLedger deprecated rather than removed, a following release that deletes it outright is the natural next step. Whether Lite Mode gains the client and proxy support it needs is still unresolved — 5.5.1 fixed it without broadening it.

S6.3

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.
