Development Handbook Changelog


This page will contain a list of most of the changes made to the ServiceNow Development Handbook

Since my goal was never to make money directly from the sales of this book (if it were, I'd have picked a wider niche!), I've decided to publish content updates directly within the same edition. This means that rather than asking everyone to pay for a new edition every a couple of months when there is a new platform version to worry about or when the standards are updated, I'll simply keep this edition up-to-date, and make those updates available for free. When a new edition does come out, it will constitute a major update to the content of the book, not minor changes, updates, or additions to the existing content.


If you purchased the a digital edition such as on Kindle, your content should be available for update automatically.
In order to ensure that you have the latest version, or to push the latest update to your Kindle or mobile device, click here then look for the Update Available button (as you can see on the right). Click that button to update the digital copy of the book on your device for free

If you purchased a paperback version rather than a digital version through Amazon, you can buy the Kindle edition for only $2 or $3. You can then just look up the specific changes you might be interested in, by referencing the changelog below.

You are of course also welcome to buy another paperback copy if you have another few bucks to spare, but I've set it up this way in order to make it as easy and cheap as possible for you to get the updates after you've bought the book.

First Edition

Version 1.4 - 2/17/18
