### Release 4.1: DB_INCOMPLETE

The DB_INCOMPLETE error has been removed from the 4.1 release, and is no longer returned by the Berkeley DB library. Applications no longer need to check for this error return, as the underlying Berkeley DB interfaces that could historically fail to checkpoint or flush the cache and return this error can no longer fail for that reason. Applications should remove all uses of DB_INCOMPLETE.

Additionally, the DbEnv.checkpoint and Db.sync methods have been changed from returning int to returning void.
