+One-line Summary: Change two files from NetCDF-4 format to NetCDF-3 (because some machines have trouble with NetCDF-4 in pnetcdf)
+
+Purpose of this version:
+------------------------
+
+There are two files in NetCDF-4 format that the model uses. Copy these files to NetCDF-3 classic format and point
+to the new version in the CLM XML database (use nccopy -k classic). There are some machines that have trouble with
+reading NetCDF-4 files in pnetcdf.
+
+There are still some NetCDF-4 files for mksurfdata_map, but some of these are required to be in NetCDF-4 format. And we only
+support mksurfdata_map and mkmapdata on cheyenne.
+
+
+CTSM Master Tag This Corresponds To: ctsm1.0.dev025 (with many other changes)
+
+Summary of changes:
+-------------------
+
+Issues fixed (include CTSM Issue #): #734
+  Fixes #734 -- Isotope historical files are in NetCDF-4 format need them in NetCDF-3 or NetCDF-5
