The Mainstore Dump Copy screens now have a column that indicates the size of a dump to help plan for proper handling of the dump.

There is now an option on the Remote Modern Support screens to configure LAN, making it easier to set up access for remote support. 

Limits for Licensed Internal Code (LIC) log have been increased so important debug information does not wrap out of the log too soon. Note that the LIC Log sizes are selectable by the customer, but have minimum, default, and maximum values. Sizes that were previously shown in kilobytes are now shown in megabytes.  This table shows the new limits and values, as compared with the previous release:
