Will I get updates for the book?

Content in this industry is always changing, which is why we're always working on updates as needed for our content.

If we update the book, whether you’ve bought it individually or as part of a Subscription, we’ll replace the old edition with the new one, so instead of buying the book again, you can simply log in to your account and read the new edition.


However, we don’t guarantee updates for any particular book. If we choose to simply update the book to be compatible with a newly released version of an OS or a library, you will receive that update for free. Some books may be discontinued, in which case there won’t be any future updates. In other cases, we may significantly or completely rewrite a book based on changes to the technology; in that case, the re-written book will not be considered an update and will instead be available as a new book.
