Summary

tell user of KDBX old version incompatible

Motivation

Currently when I attempt to open a previously-created KDBX v3 db, the iOS app just says, “Database Open Error The database file is not a valid one.”

It should also say, “If you’re able to open this in other KeePass-compatible apps and the file extension ends in .kdbx, then this might be because the db is an older version (prior to kdbx v4).

As of this writing, this app only supports opening the latest version of keepass databases, which is kdbx version 4. “

Release 0.7.0 fixed the issue by adding proper error messages when user attempts to open a database with old format
