6 concurrent RC2 related votes are occurring on https://lists.apache.org/list.html?dev@grails.apache.org, each votes lasts for a minimum of 72 hours. Since Grails is incubating at the Apache Software Foundation, then the same votes will occur again on https://lists.apache.org/list.html?dev@groovy.apache.org, Apache Groovy is our incubation host. Once those both pass, the projects will be released. You can easily subscribe to either mailing list using the 'Subscribe to list' button on the left navigation.
