William,
With the MyEclipse 2015 CI (Continuous Integration) stream, you will have access to new features and important fixes without having to wait for a GA release that could be a few months down the road. MyEclipse 2015 CI will receive frequent updates as development progresses towards our GA release.
While CI builds are stable and are tested, a few omissions and rough edges are to be expected. GA is currently scheduled for release between mid September and October.
Let us know if you have further questions.
