This is the first CI release of the r2book. Major changes are on the build system which is now based on pandoc (pdf/epub) and mdbook (html). Autogenerated builds of the book will be published in the release page from now on. So everything is contained and the users have full control to build their own books without depending on privative solutions.

Don't take this tag as a big milestone for the book. it's just one more iteration of lazy improvements, there are still a lot of chapters in the book to review, update, fix and write to cover all the r2 features and capabilities!
Enjoy it back! Thanks for contributing!
