One of the most interesting improvements of Liferay 6 for developers is that the plugin infrastructure has improved considerably. For example, the hook plugins are now much more powerful and allow customizing the platform in a very maintainable way. Also, the old extension environment has been moved inside the plugins SDK as what are known as Ext plugins.

After publishing our new set of documentation pages and specially the new Developer's Guide, we've been asked for more detailed documentation about Ext plugins. We've been working on it during the last few days and it's now ready and published in the documentation pages.

It includes information about how to migrate an ext environment as well as how to develop and deploy it. We hope you like it.
