Windup has another version out - 2.7.0.Final.
Download at the Windup website.
The main addition is the rules for EAP 5 to EAP 7 rules.
Use the --target eap:7 parameter to use them.
Thanks Marek for all the hard work and all who contributed the knowledge.
PS: There's one little, tiny, bug which was not found until a live demo, so if you hit that, please wait for next release or fix with the jar in the attachment.
