2.0.0 (2026-06-30)

Bug Fixes

  • correct sift-down child selection and pop in Heap (6452fcc)
  • drop null labels from filtered outNeighborLabels (efada0e)
  • key Dijkstra distance/prev maps by node label (ef75be4)
  • ringbuffer: reject capacity < 1 to avoid modulo-by-zero (7b56140)
  • spatialhash: reject cellSize <= 0 to avoid division-by-zero (5075e24)
  • Remove C# build for now. (f537e65)
  • astar: reopen closed nodes for non-consistent heuristics (046167a)
  • Try to fix cs build by removing trailing / (265bb99)

Features

  • add 7 new data structures, A*, MST, traversal, and project setup (7430f30)
  • Add graph, node interfaces. Add BF DF iterators. (2af5219)
  • graph filter, weighted Dijkstra, heap remove, iterator inline (0cc0197)

Performance Improvements

  • traversal: count nodes during in-degree build in topologicalSort (5f71094)
  • replace JSON default hasher in Set with identity-based hashing (4d636a0)

Reverts

  • restore object-keyed Dijkstra distance/prev maps (f72fe2d)

BREAKING CHANGES

  • default equality for objects is now identity-based (same
    reference = same item). Callers needing structural equality should
    pass an explicit hasher.
