Hello, I have cloned JRA-43658 since this is still reproducible on 7.0.5 and 7.0.9.
Regardless of the context path setup for JIRA, accessing the Release Notes link from a version's details page builds a URL with context path /jira, which possibly results in a 404 error.
- Setup a context path different than /jira for your JIRA instance;
- On a Scrum board, expand the Versions sidebar, then expand one of the versions and click Details;
- Click Release Notes, just below the version's name;
- Notice the URL built uses /jira for its context path, which results either on a blank page or a 404 error;
The context path should be retrieved from the application's Base URL, and not hard-coded.
Every time the URL for Release Notes is built, the context path is set to /jira.
You can manually edit the URL from your web browser, adding the right context path (as shown in screenshot below).
Add the following script in JIRA's Announcement Banner
