1+1.2.3.0

3+* `unsnoc` implemented

5+* Bug fix: the lazy `takeWhileEnd` function violated the

6+ [lazy text invariant](https://github.com/bos/text/blob/1.2.3.0/Data/Text/Internal/Lazy.hs#L51).

8+* Spec compliance: `toCaseFold` now follows the Unicode 9.0 spec

9+ (updated from 8.0)

10+

11+* Bug fix: Fixed usage of size hints causing incorrect behavior (gh-197).

12+

13+* Improve UTF8 decoder error-recovery (gh-182).

14+

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

16+

17+

18+1.2.2.2

19+

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

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

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

23+

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

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

26+ smaller code generated.

27+

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

29+ used after some rewrite rule tweaking.

30+

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

32+

33+* Bug fix: a logic error in `takeWord16` is fixed.

34+
