Release 5.4.1

Changelog

Added

• Update Dependencies Maven Configuration
• Run Tests Maven Configuration
• Build Jar Maven Configuration
• A specialized, array-backed binary heap tailored for A*

Changed

• Revamp README for better engagement – add humor, benchmarks, and real-world demos to combat stagnation
• optimized core data structures for reduced GC pressure and cleaned up legacy code
• Switched internal Open Set implementation from Fibonacci to PrimitiveMinHeap.
• ~3x to 4.5x faster pathfinding in benchmarks due to improved CPU cache locality.
• Achieved true zero-allocation operations within the Open Set (eliminated millions of Node wrapper and Double boxing objects).
• Renamed NodeCostProcessor -> CostProcessor
• Renamed NodeValidationProcessor -> ValidationProcessor
• Renamed NodeEvaluationContext -> EvaluationContext

Fixed

• removed legacy lazy computing of hcost
• Fixed subtle yet crucial a control flow bug where updates to nodes in the Open Set were ignored, ensuring the optimal path is always prioritized.

• Experimental annotation

Changed

• Optimized tie-breaker calculations
• Cost now only can be positive

• Refactored heuristic implementations with DistanceCalculators

Fixed

• Fixed SquaredHeuristicStrategy with now a matching squared manhattan, octile and heightDiff calculation which improved performance

Removed
