POPFile 1.1.0 will be the first release to support SQLite 3.x databases. Although POPFile 1.1.0 will automatically upgrade old SQLite 2.x databases to the new format, the current installer code does not ensure that the upgrade progress messages are displayed.
Database upgrades can take some time so it is important that the user is informed that something is happening.
When updating the installer to handle the SQLite 2.x to 3.x upgrades, also need to take advantage of the recent changes which make POPFile 1.1.0 more installer-friendly. It should be possible to make this part of the installer code much simpler and therefore easier to maintain.
