What's New
Introduces graph database pathfinding (A*, Yen's) and CCH indexes, replacing keyboard control logic.
Breaking Changes
- RDB encoding updated from v19 to v20, requiring migration for persistence compatibility.
New Features
- A* search algorithm with optional heuristic for optimal pathfinding.
- Yen's k-shortest paths algorithm for finding multiple shortest routes.
- CCH path index for bidirectional Dijkstra queries.
Improvements
- Optimality fixes for path accounting and cost-model logic.
- Replication decoder no longer requires full-sync.
- Incremental maintenance for CCH indexes.
Bug Fixes
- Crash fixes for MERGE and UPDATE_EDGE clauses.
- Fix for replica SIGSEGV on id divergence.
Upgrade Notes
Migrate database persistence as RDB encoding was updated from v19 to v20; decoder changes require attention for replication setups.
