What is Madeleine?

  "Are you still using a database?"

  Madeleine is a Ruby implementation of Object Prevalence: 
  Transparent persistence of business objects using command
  logging and snapshots.

It's been a while, so it felt like a good time to do a new release!

News in Madeleine 0.4:

  * Deprecated ClockedSnapshotMadeleine
  * Added execute_query()
  * API documentation in RDoc format

The new execute_query() method allows you to easily do consistent
queries on your system. (It keeps a lock while running to prevent
updates from happening at the same time).

Have fun!
