1.10      2013-09-27
[FEATURES]
- added 'no_wide_chars' option to strip words with such characters
  from the output.  This may help spellcheckers that can't cope
  with UTF-8
[CHANGED]
- improved punctuation stripping algorithm for better word
  isolation (example C<< "hello". >> now is found as "hello")
- strips all word that do not have at least one \w character
  as a spellchecker isn't likely to do anything useful with them
[DOCUMENTED]
- added recommendations for dealing with character encoding

1.09      2013-09-25
[FIXED]
- stopwords with 's are learned without 's to match how they are
  checked
[CHANGED]
- leading and trailing punctuation is entirely stripped since the
  spellchecker won't care anyway.  Trailing periods are *not*
  stripped as they might be abbreviations ("Ph.D."), but such words
  are checked against the stoplist both with and without
  trailing periods to account for abbreviations and words at the
  end of a sentence.
