Naturally, we'll be adding new information to our Art Head Start eBook from time to time. Minor additions will be added to the existing version number. For example, if you have version 2b, the next minor version update will be version 2c. You may obtain these minor upgrades for free by sending an email request to the author at: email@example.com.
Major eBook updates will have a new version number, such as Version 3a. These major updates will be sold as a new eBook, at the price which is current at the time.
