Changes

0.9.0

This version changes the way Float and Double are serialized to a more compact format. Old data should be migrated automatically. As a result, however, the Float and Double data serialized by this version can not be read by older versions of safecopy.

This change originated as a modification to the way cereal 0.5 serializes Float and Double.
