DataMapper version 0.2.3 has just been released. DataMapper is a Ruby O/R Mapper based on the Data Mapper Design Pattern. It’s similar to ActiveRecord in usage, with an emphasis on Domain Models. CHANGELOG: – 0.2.3 - Added String#t for translation and overrides for default validation messages - MAJOR: Resolve issue with non-unique-hash values and #dirty?; now frozen original values are stored instead - Added Base#update\_attributes - MAJOR: Queries are now passed to the database drivers in a parameterized fashion Check it out at [http://datamapper.org](http://datamapper.org), or in #datamapper on [irc.freenode.net](http://irc.freenode.net). ---
