Sending an updated Kindle edition to previous customers

I created a new edition of my book, Castle Falcon, including a new map. While updating the book was simple enough in both Kindle and Createspace, I was hoping I could convince Amazon to provide free updates of the improved book to previous Kindle purchasers.

Guess not. From their Help section:

“Some examples of corrections that don’t justify sending updates to customers who previously purchased your book are:

•   New Content Added: Chapter(s) or page(s) added, deleted or revised; new images added; bonus chapter added.”

Oh, well.

For the record, there is a list of changes that do justify an update to Kindle customers at Amazon’s help site.  Mostly they involve major mistakes.
