Due to improvements in message store system (and new support for identities), starting with next version, OE Classic will no longer support older beta version database formats (last version which used these was released on Jun 20th, 2011). As program automatically upgrades database format every time you install new version, most likely you can safely ignore this notification. We will of course, be providing older version (on demand) which you can use to convert older messages database.
Program will also notify you if you need to take any action (if it detects older database format).
