msitarzewski/agency-agentsSep 30, 2026 → Sep 30, 20260 days between releases
What's New
Introduces advanced path-finding algorithms and a new CCH path index, alongside crash and replication fixes.
New Features
- A* search with admissible haversine heuristic for time-weighted networks.
- Yen's k-shortest paths algorithm with goal-directed spur search.
- CCH path index for faster repeated shortest-path queries.
- db.idx.cch.query procedure for rank-pruned bidirectional Dijkstra.
Improvements
- RDB encoding upgraded from v19 to v20 to support CCH serialization.
- Replication fixes for SIGSEGV during UPDATE_EDGE and UPDATE_NODE operations.
- Crash fixes for MERGE operations and mid-plan-build clause errors.
Bug Fixes
- Crash on MERGE preceded by an erroring clause.
- Crash when a clause errors mid plan-build.
- Replica SIGSEGV applying UPDATE_EDGE/UPDATE_NODE with diverging IDs.
Upgrade Notes
Requires DDL changes to create or drop the new CCH index. Ensure your RDB encoding is compatible with version 20 to support the new serialization format.
