What's New

Complete rewrite of the query engine to Rust while maintaining API compatibility.

Breaking Changes

Mixed 4.x and 6.0 nodes cannot replicate in the same primary/replica set.
The `EFFECTS_THRESHOLD` configuration is now ignored as effects are the only replication mechanism.
Docker tags `latest` now point to the Rust engine, while `latest-alpine` remains on the C engine.

New Features

Rust-based query engine.
RediSearch 8.6.1 integration.
Faster query execution for filters, label checks, and aggregations.
Lower memory usage on write-heavy workloads.

Improvements

Replicas now apply effects instead of re-running queries.
Upgraded to RediSearch 8.6.1 from 2.6.23.
`GRAPH.BULK` no longer reserves memory based on client declarations.

Upgrade Notes

Do not mix 4.x and 6.0 nodes in the same primary/replica set. The `EFFECTS_THRESHOLD` config is ignored, and `TIMEOUT` is deprecated in favor of `TIMEOUT_DEFAULT` and `TIMEOUT_MAX`. Docker `latest` now points to the Rust engine.
