What's New

Major version jump introduces Rust engine, breaking replication compatibility.

Breaking Changes

  • Cannot mix 4.x and 6.0 nodes in the same primary/replica set
  • Configuration change: `EFFECTS_THRESHOLD` is now ignored
  • Alpine and macOS images remain on 4.x; 6.0 has no Alpine images yet
  • Missing algorithms: A*, CCH, Leiden, and Louvain are not yet available in 6.0

New Features

  • New Rust query engine replaces the legacy C engine
  • Replication via effects (v3 format)
  • RediSearch 8.6.1 integration

Improvements

  • Docker images now support AMD64 and ARM64
  • Improved `GRAPH.BULK` memory handling

Upgrade Notes

Upgrade every node in a replication group together as 6.0 replicates writes only as effects in a new format. Note that `EFFECTS_THRESHOLD` is ignored and Alpine/macOS images remain on the 4.x C engine.
