What's New
Major version jump introduces Rust engine and parser changes, requiring careful query review.
Breaking Changes
- Parser rejects specific syntax patterns like `NOT NOT`, `MATCH MATCH`, and `SET [n)`.
- Index OPTIONS now strictly require `dimension` and `similarityFunction` for vectors.
- Parser now accepts `IS NULL IN` syntax, potentially breaking legacy code using `IN NULL`.
New Features
- Rust engine stabilization with improved subquery handling.
- Vector KNN queries optimized to clamp `k` instead of allocating memory.
- Parser enhanced to handle edge cases like named paths and block comments.
- Docker image updated to remove deprecated `util-linux` and fix permissions.
Improvements
- Vector KNN queries optimized for memory efficiency by clamping `k`.
- Rust toolchain updated to LLVM 23 and libc++ 23.
- Updated rustls dependency to version 0.23.45 for security.
- Prompt tracking speed improvements in the older release.
Bug Fixes
- Subqueries importing no variables no longer read outer query variables.
- Temporals are no longer matched by numeric range-index predicates.
- `startNode()` and `endNode()` now accept null values.
- Large prompt tracker exports no longer get stuck in progress.
Upgrade Notes
Review and update Cypher queries to remove rejected syntax patterns like `NOT NOT` or `MATCH MATCH`. Ensure vector index OPTIONS explicitly define `dimension` and `similarityFunction`. Update Rust toolchain to LLVM 23 and libc++ 23 to support new features.
