JMWE 6.0.0 brings the following improvements:

Jira 8 compatibility

JMWE 6.0.0 is fully compatible with Jira Software/Core 8, as well as with Jira Service Desk 4.0. JMWE 6.0.0 is also backward compatible with Jira 7.0.11 and above.

Conditional validation

JMWE Validators now support a new Conditional Validation option that allows you to specify under which circumstances validation should occur. For example, if you want to make a field mandatory only if the issue is of Blocking priority, you can use the Field Required Validator together with the following condition: issue.getAsString("priority") == "Blocker"

Groovy improvements

And a few bug fixes
