We should note that the "Highlights" below omit one important change in how Xyce binaries are deployed, and one significant bug fix.  Both of these are mentioned in the release notes and related documentation, but are worthy of amplification:

• Xyce binaries are no longer shipped with wrapper scripts "runxyce" and "xmpirun" --- one now runs Xyce in serial by invoking its binary directly, and in parallel by constructing an appropriate mpirun command line.  Both methods are documented in Chapter 2 of the Users' Guide.
• A long-standing bug relating to handling of hierarchical ".lib" statements has been fixed.  This is bug 907-SON, which should have been mentioned in the highlights, but appears only on the third page of the "Fixed Defects" table of the release notes.
