* Documents now load from database using write_key instead of public accessors which allows you to update public accessor and not affect querying/loading from the db
* Document.set now typecasts values before performing the set
* Times at the end of a month no longer round up. Milliseconds are now removed from times.
* Float.to_mongo(nil) now returns nil.
* MongoMapper::Query is now powered by Plucky. Deeper Plucky integration is slated for next release.
* Custom gemspec/rake tasks instead of jeweler. More simple.
