What's New
Introduces advanced path-finding algorithms, CCH path index, and RDB encoding v20 upgrade.
Breaking Changes
- RDB encoding v20 changes serialization format.
- Decoder logic changes remove full-sync requirement.
New Features
- A* search with admissible haversine heuristic.
- Yen's k-shortest paths with goal-directed spur search.
- CCH path index supporting DDL and Query operations.
- All-shortest-paths and k-shortest-paths procedures.
Improvements
- Incremental maintenance for CCH path index.
- Optimality and cost-model fixes for path algorithms.
- Decoder logic improvements removing full-sync requirement.
Bug Fixes
- Fixes crash on MERGE preceded by an erroring clause.
- Fixes crash when a clause errors mid plan-build.
- Fixes Replica SIGSEGV applying UPDATE_EDGE/UPDATE_NODE.
Upgrade Notes
Requires migration due to RDB encoding v20 serialization format changes. Decoder logic updated to remove full-sync requirement.
