+## [0.3.4] - 2025-06-28
+- Add `dijkstraAssocCost` and `dijstraAssocCostM`, which make it easier to

+- Fix bug in `dijkstraAssocM`, where the prior cost was not propagated to new states.
+
+## [0.3.3] - 2024-11-08
+- Add `pruningAssoc` and `pruningAssocM`, which allow for easy pruning of states based on cost.
+- Add monadic versions of `dijkstraAssoc` and `astarAssoc`
+
