This week, InfoQ published an updated version of the popular book, Getting Started with Grails, and it is now available for download as a free PDF 1 (+).  In addition to being the first book fully compatible with Grails 1.2, the second edition expands on the coverage of the first edition.  You'll find entire new sections tackling a variety of key topics from plugins, to codecs, to services, and more.  And thanks to the testability improvements introduced in Grails 1.1, you'll also find an increased emphasis on testing.
