      • [dictutils.FrozenDict][dictutils.FrozenDict] brings immutable mapping to a module near you (#105)
      • [setutils.complement()][setutils.complement] introduces "negative" sets, useful for exclusion and many other set operations
      • [iterutils.soft_sorted()][iterutils.soft_sorted] allows for looser, more flexible sorting of sequences
      • [iterutils.flatten_iter()][iterutils.flatten_iter] and [iterutils.flatten()][iterutils.flatten], to collapse nested iterables. (#118)

    • funcutils improvements
      • [FunctionBuilder][funcutils.FunctionBuilder] and [funcutils.wraps][funcutils.wraps] now support coroutines/async (#194)
      • [FunctionBuilder.add_arg()][funcutils.FunctionBuilder.add_arg] allows the addition of arguments to the signature, to match [FunctionBuilder.remove_arg()][funcutils.FunctionBuilder.remove_arg] (#201)
      • Similarly [funcutils.wraps()][funcutils.wraps] now takes an "expected" argument, to complement "injected" (#161)

      • [urlutils][urlutils] now has better IPv6 support and URL can be used more natively like a string
      • Improve singularization in [strutils][strutils]
      • Fix some deprecation warnings in Python 3.7 (#165, #196)
