2017.5 contains improvements to what is logged when things happen in process apps on Barium Live. Process Application administrators can now potentially see more and better logging information in the process application event log.
We have also made improvements to Drop-Down form fields making them load faster as well as being searchable. No changes have been made to the existing forms but all new drop down fields that are added to new or existing forms will have this improvement.
Go to the Barium Live Help Centre and the 2017.5 - Change log for full details about this upgrade.
