We’ve found a problem that affected zero downtime upgrades, so we’ve fixed it and released another Release Candidate. You can still use it to test the changes released so far—the next stop is most likely the official release.
For details on the available changes, see Preparing for Jira 8.17 . You can download the RC from this page . If you’re using maven.atlassian.com, make sure to download 8.17.0-m0006.
Should you have any comments, just post them below.
Happy testing,
The Jira team
