Many CDP users have moved on to Release 4.5, which came out in November 2001. You would therefore belong in the '4.5 to 5' category when ordering Release 5 and be able to purchase at a reduced price.

The Upgrade to CDP Release 5 is a comprehensive package that contains the complete CDP System software and documentation.

Upgrade from 4.5 to 5.0 For MS Windows (Includes Single User License)	£39.00
Upgrade from P4.5 to 5.0 For MAC OS X (Includes Single User License)	£39.00

To keep things simple and encourage upgrades, we are allowing anyone with any version prior to 4.5 to upgrade at the same price. You would therefore belong to the 'Pre-4.5' category when ordering Release 5. Those with a Release 3 version will not have had the benefit of the new graphic user interfaces, so an upgrade to Release 5 will bring many benefits.

The Upgrade to CDP Release 5 is a comprehensive package that contains the complete CDP System software and documentation.

Upgrade from Pre-4.5 to 5.0 For MS Windows (Includes Single User License)	£69.00
Upgrade from Pre-4.5 to 5.0 For MAC OS X (Includes Single User License)	£69.00
