Changelog

main

3.15

  • Add CCList.split_result (#459)
  • pretty printer in MultiSet
  • CCHeap: building a heap from an almost-sorted sequence
  • perf: CCHeap: building a heap from n elements is now in time O(n) instead of O(n log n)
  • perf: CCHeap: filter and delete_all are now in time O(n) instead of O(n log n), and they ensure physical equality (for delete_all this is a bugfix)

3.14

  • predicate combinators: and_pred and or_pred

  • feat pp: add a bunch of extensions

  • Kleisli Composition Operator and Apply_or for option/result/fun (#455)
