14+* Reduce memory overhead in `encodeUTF8` (gh-194).

15+

17+

18+* Minor documentation improvements (`@since` annotations, more

19+ examples, clarifications).

22+

23+* The `toTitle` function now correctly handles letters that

24+ immediately follow punctuation. Before, `"there's"` would turn into

25+ `"There'S"`. Now, it becomes `"There's"`.

26+

27+* The implementation of unstreaming is faster, resulting in operations

28+ such as `map` and `intersperse` speeding up by up to 30%, with

29+ smaller code generated.

30+

31+* The optimised length comparison function is now more likely to be

32+ used after some rewrite rule tweaking.

33+

34+* Bug fix: an off-by-one bug in `takeEnd` is fixed.
