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.

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.

Pixelfed vs Apache RocketMQ: editorial side-by-side

P5.0

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.

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.
