Update 1 for "NetBeans Platform for Beginners"
By Geertjan-Oracle on Mar 26, 2014
Books on Leanpub.com are never done. The authors of "NetBeans Platform for Beginners" plan to release a new update each month, which everyone who buys the book will automatically receive. With permission, below is the update page for the first update of the book, pretty cool stuff there.
I think "NetBeans Platform for Beginners" is a fantastic resource for NetBeans Platform developers, all the more so in combination with Leanpub.com, which is a simply wonderful authoring/publishing platform.
