We try to ensure that all books in Early Access have code available to use, download, and fork on GitHub. This helps us be more agile in the development of the book, and helps keep the often changing code base of new versions and new technologies as up to date as possible. Unfortunately, however, there will be rare cases when it is not possible for us to have downloadable code samples available until publication.

When we publish the book, the code files will also be available to download from the Packt website.

The publication date is as accurate as we can be at any point in the project. Unfortunately, delays can happen. Often those delays are out of our control, such as changes to the technology code base or delays in the tech release. We do our best to give you an accurate estimate of the publication date at any given time, and as more chapters are delivered, the more accurate the delivery date will become.

All modern operating systems ship with ZIP file extraction built in. If you'd prefer to use a dedicated compression application, we've tested WinRAR / 7-Zip for Windows, Zipeg / iZip / UnRarX for Mac and 7-Zip / PeaZip for Linux. These applications support all extension files.
