FSI new features:

Fix ID / Description
81024048 / Provided support for clone operation to a different file system
81024779 / Support for larger than 8 Gb files
81024915 / Support for cloning a local directory
51005270 / Updated the CLI (ptcli) to support cloning a local directory.

VTL new features:

Fix ID / Description
81023691 / A new option was added:
'update_memory_requirements_file_max_tapes' to vtlutil utility.
This method updated the memory_requirement.xml file in order to
reduce the memory consumed by VTL tapes, according to the
following logic:
‐ The new limits fall between 128 and 256 on a 32-byte boundary (according to the current library configuration).
‐ The new value must be equal to or greater than the current number of CONFIGURED tapes.
‐ If the calculated new limit is greater than the current limit, no change is performed.
The backup configuration file with the current configuration is also generated.
