hyphenation-0.4: CHANGELOG.markdown

0.4
---
* Removed Farsi. We had no pattern files.

0.3
---
* Added Friulan, Piedmontese, Romansh and Thai language hyphenations.

0.2.2
-----
* Flagged `Text.Hyphenation.Language` as `Trustworthy`. It has benign side-effects that cause it to read hyphenation files lazily from the installed `data-dir` but nothing else.
