The beta release (this is the final release of Jira 8 EAP and is the version that will be Jira 8.0 unless any major issues are found) was released on Friday. So to answer your question, yes Jira 8.0 is imminent and will probably drop in about 2 weeks as that’s been the cycle for EAP releases.
What is a Beta Release?
We’ve heard from developers in the past that the last EAP version doesn’t match what gets released as the final version. To address this concern we have added a beta release version into the EAP pipeline. This release is the planned bits we will release to the public. This allows you to test any apps/integrations on the actual bits to be released before they are released.
