Jason Greene reopened JBAS-8036:
--------------------------------



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.
