I'm quite certain "Grails" should not be fully capitalized as "GRAILS". Also, Grails 3.0 and Grails 2.5 have both just been released together, a few days apart,

I'm quite certain "Grails" should not be fully capitalized as "GRAILS". Also, Grails 3.0 and Grails 2.5 have both just been released together, a few days apart, as two separate products and I'm not sure how compatible they are with each other so you might want to specify Grails 2.x or Grails 3.x.
