Check current board version in incremental update packages

Support thread

User downloaded 3.0.7 to 3.0.7-pl1 update package and ran it on 3.0.6 board. The update process then executed "successfully" without making, supposedly, any of the 3.0.6 to 3.0.7 changes. The user then restored database from backup and reran the update using the correct package.

The suggestion is to check current board version in updating code when using version-specific incremental update packages.
