Jason Greene reopened JBAS-8369:
--------------------------------
Due to feedback from the community, I have split the AS7 and AS6 projects and reopened all
unscheduled AS6 issues that are a year or less old. This will make it easier community
members to find and work on them.
Future releases beyond 6.1 can be done provided a community member steps up to coordinate
them.
