The new release includes quite a few refinements such as auto registering the vocabularies via the inherited hook and adding various DataTypes such as Boolean, Float, ISO8601Date, etc. To improve output when using pp or y on Item#to_h the vocabulary has been removed.

There are a couple of changes to watch out for:

• When describing a vocabulary types has been deprecated in favour of extract. This was done in case greater flexibility was needed at a later date by providing extract with a block. If this happens extract would make more sense as a name.
• String can no longer be used as a type when describing a Vocabulary, instead use DataType::Text
• Properties marked as has_one now output a single value instead of an Array
• Document#search now only uses a Regexp to search with as this greatly simplified the code

The project would benefit from greater collaboration, to aid this Bundler support has been added.
