Hey guys,

I'm not very active lately due to the great growth that we are experiencing in Spain and the increasing work associated to the upcoming new version, Liferay 6.1. The reason for this blog post is to announce some great news: The second edition of the Developer's Guide is now available at www.liferay.com/documentation

The document is available online for browsing and searching and can also be downloaded in PDF. Note that the document has a Creative Commons license so feel free to distribute it to make sure it reaches every Liferay Developer out there.

This new edition comes with many many improvements and several new chapters. Here is a quick list of the most significant changes:

• Overall review of the style by Rich Sezov
• Overall review of the guide and rewrite of some sections by Jorge Ferrer.
• Rewrite of the introduction to make it more welcoming to new developers.
• New section: “Understanding the two phases of portlets: action and render”
• Extended information of the chapter about “Ext Plugins” by Tomas Polesovsky. New section on JSR-286 security by Tomas Polesovsky.
• New chapter about the Asset Framework and quick introduction to other Liferay frameworks.
• New chapter about Liferay IDE
• New chapter for Conclusions with information about how to learn more after reading this guide.
• New chapter with links to reference documentation.

But this is only the beginning. We know that you want even more developer documentation and we are already working on a new edition of the guide and additional reference materials for you. Keep an eye for updates in the near future.

I want to give an special THANKS to Tomas Poleovsky for his help extending two of the most important chapters of the guide and also with his help in the review. We also had a lot of help from reviewers, so thanks a lot also to Daniel Sanz, Alberto Montero, Sergio González, Juan Fernández, Julio Camarero from the office in Spain and Tobias Käfer, Oliver Bayer, Deb Troxel, Juan Gonzalez, Boubker Tagnaouti and David Nebinger from the Community Leadership team.

Remember that if you find any issue with any of the official guides or want to make suggestions you can use the Documentation Suggestions category in the message boards.
