I shipped new dm-datastore-adapter today.

• http://github.com/genki/dm-datastore-adapter/tree/master

This update is a long jump from previous version. It includes following functions

• Transaction. It utilizes the DataStore's Transaction API
• OR conditions
  ruby>>
  Post.all(:id => [1,2])
  <<--
• NOT conditions
  ruby>>
  Post.all(:id.not => 4)
  <<--

So now we can use most of functions defined in DM by using this adapter.

Enjoy!
