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 Signal Desktop?

Signal adds granular notification controls: badge content, muted threads, restore defaults

Signal Desktop is in a steady beta cadence, shipping routine maintenance alongside occasional UX expansions. The most substantive recent change is a notification settings overhaul in v8.27 giving users per-badge and per-muted-thread control — filling a settings gap that had been there since Signal's desktop client launched. The v8.28 beta series has been pure maintenance so far.

Apache RocketMQ vs Signal Desktop: 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.

S5.0

Signal adds granular notification controls: badge content, muted threads, restore defaults

◆ Current state

Signal Desktop is in a steady beta cadence, shipping routine maintenance alongside occasional UX expansions. The most substantive recent change is a notification settings overhaul in v8.27 giving users per-badge and per-muted-thread control — filling a settings gap that had been there since Signal's desktop client launched. The v8.28 beta series has been pure maintenance so far.

◆ Where it's heading

Signal's desktop releases follow a consistent pattern: one meaningful UX addition per minor version cycle, surrounded by maintenance betas. The direction is toward finer user control over notification behavior and UI density (zoom levels, group member search improvements shipped in prior cycles). No architectural pivots are visible — Signal is not moving toward richer media, AI features, or monetization hooks.

◆ Prediction

The v8.27 notification changes will land in stable shortly. The v8.28 beta series suggests another incremental UX feature is in development, though the entries don't reveal what.
