Enterprise Application Platform
Background
So this post is more of a reference for myself, since I frequently get asked these questions by customers. What used to be just called JBoss, in version 4 and 5, eventually got rebranded as JBoss Enterprise Application Platform, or EAP for short.
JBoss AS was the community project, which has evolved into a new community project called Wildfly.
Versions of EAP don’t directly correspond with versions of Wildfly though, as EAP is the “product” and Wildfly is the “project”.
A lot of bug fixes happen upstream, and eventually get ported back into the product by the Red Hat engineering team. Since EAP is their supported offering, the bug fixes actually get ported back into multiple versions of EAP.

These are awesome pages that get updated regularly, that describe the capabilities of the platform. Unfortunately, you gotta have a Red Hat account to view them, so not everyone can see how great they are.
