JMWE 6.4.0 brings the following improvements and bug fixes:

Improvements

• The Jira Service Management (formerly Jira Service Desk) request "channel" is now available from the Issue interface as the channel property
• The Organizations field of Jira Service Management requests can now be set by organization name in addition to organization ID
• Emails sent by the Email Issue(s) Post-Function now include an "In-Reply-To" header
• The Set Field Value Post-function now support the "run as" option
• The Comment [Related] Issues post-functions now always add the sd.public.comment comment property, even for public comments
• The Email Issue post-function now ignores recipients without an email address instead of raising an error
• The Transition related issues post-function now includes an option to trigger the WorkflowManualTransitionExecutionEvent event
• Groovy scripting: a new DateOnly class extends the Date class and allows creating date-only values, which can be created in a user's time zone. This is useful to set fields like the Due Date field.

• [JMWE-838] - java.lang.NoClassDefFoundError exception while testing or running a Groovy script
• [JMWE-881] - Transition current issue should not have a "workflow name" column in the transition table
• [JMWE-886] - Cannot set Customer Request Type by name after changing project key
• [JMWE-890] - the setFieldValue method can only modify one field on jqlSearch results
