JMCF 2.1.0 brings the following improvements:

Jira 8 compatibility

JMWE 6JMCF 2.01.0 is  is fully compatible with Jira Software/Core 8, as well as with Jira Service Desk 4.0. JMWE 6.0 JMCF 2.1.0 is also backward compatible with Jira 7.0.11 and above.

...

Statistics-compatible duration fields

JMCF Calculated (Scripted) Duration fields and Time In Status fields can now use a statistics-compatible search template, which means that these fields can now be used in Statistics gadgets such as the Pie Chart.

Groovy improvements

• An isInternal() method on Comment objects to check whether a comment on a Jira Service Desk issue is Internal or Shared with customer
• A secondsBetween global function to easily calculate the duration, in seconds, between two dates
• A workdaysBetween global function to calculate the number of workdays (excluding weekends) between two dates
  
• The Groovy script tester page has been renamed to Groovy Console

...

• An asUser global function to run part of a calculated (scripted) custom field's script as a specific user. This is especially useful for scripts that need to access the API of another app, and this API relies on the "current user" to secure access to data.
