What's New

Adds advanced pathfinding algorithms and a CCH path index for faster query performance

Breaking Changes

  • RDB encoding updated to v20

New Features

  • A* search algorithm with haversine heuristic
  • Yen's k-shortest paths algorithm
  • CCH (Contraction Hierarchies) path index
  • RDB encoding v20

Improvements

  • Optimality fixes for pathCost and hop-count accounting

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

Upgrade Notes

Upgrading requires updating to RDB encoding v20. The decoder's full-sync requirement has been removed. Fixes for MERGE and plan-build errors should be tested thoroughly.
