From the Garmin MapSource Software Update page:

Changes made from version 6.1 to 6.3:

* Changed software version number from 6.1 to 6.3.
* Fixed issue with searching in multi-product families where a map from the wrong product could be shown behind the search result.
* Fixed some alignment issues in the Japanese and Korean resource localizations.

Uhh, thanks for letting us how about the version change, Garmin.
