Can't say for 100% for the CCC version since I have an E53, but the high version had a significant update. The 2008.1 disk had something like 1.5 million POI's while the new 2009.1 has 7.28 million POI's. They usually release 2 a year, but given the huge update, they only released 1 in 2008 (version 2008.1) and no 2008.2 version ever came out.
