Difference between Java EE 5 and Java EE 6

What a开发者_StackOverflow社区re the main differences of Java EE 5 and Java EE 6 ?

Oracle has a three part article detailing the changes: Introducing the Java EE 6 Platform: Part 1

I know it's kind of nitpicky but the enterprise editions dropped the "2" from their acronyms sometime ago, it's Java EE 5 / Java EE 6 now. For differences between the two, its easy enough to simply look at the specs:

Java EE 5 http://jcp.org/en/jsr/detail?id=244
Honestly some of the major things that they have added have been available in Spring for quite some time dependency injection and bean validation.
