JBoss Enterprise Application Platform 8.1 Update 6 Release Notes
Updated
In order to better meet customer expectations, micro releases for JBoss EAP 8 have been discontinued and replaced with updates delivered on a repeating schedule.
Each new update will contain a number of bug fixes for customer reported issues and potentially a number of security fixes. We expect that the updates will substantially reduce the number of individual patches that we produce and that customers must manage to keep their installations up to date.
