This release contains an update (from the 1.03 release) to the locking protocols used within DBISAM and internal changes to the index format to fix a problem with deleted records showing up in filtered record counts. These locking changes require that the internal version number of the database system be incremented so that two different versions of DBISAM (with incompatible locking protocols) are not used in a multi-user application at the same time.
