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 Fonoster?

Fonoster now cleans up deleted workspaces and stops exposing stored secrets.

Fonoster ships minor versions almost daily. v0.51 to v0.53 added Anthropic, Google and Groq models, TTS voice choice and one-switch call recording. From November 10, v0.54 to v0.56 added branded emails, legal pages, webhook event lookups and API key rotation, and v0.57 returns secret values only to API keys, cancels a deleted user's plan, and ends a deleted workspace's calls and resources.

Apache RocketMQ vs Fonoster: 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.

F7.5

Fonoster now cleans up deleted workspaces and stops exposing stored secrets.

◆ Current state

Fonoster ships minor versions almost daily. v0.51 to v0.53 added Anthropic, Google and Groq models, TTS voice choice and one-switch call recording. From November 10, v0.54 to v0.56 added branded emails, legal pages, webhook event lookups and API key rotation, and v0.57 returns secret values only to API keys, cancels a deleted user's plan, and ends a deleted workspace's calls and resources.

◆ Where it's heading

After a quick run of voice-AI options, Fonoster has turned to what a hosted service needs before paying customers rely on it: legal pages, billing correctness, webhook debugging and account deletion that actually removes data. The cadence stays daily and the changes stay incremental.

◆ Prediction

More account and billing lifecycle work is likely next, since v0.57 adds a billing test case and deletion rules in the same release.
