+One-line Summary: Fix some NFIX variables, update cime/cism for upgraded hobart new glade, new diagnostic fields, update cmip6 output
+
+Purpose of this version:
+------------------------
+
+Add some new diagnostic fields. Some needed for CMIP6. Update the CMIP6 user-mods output.
+Fix a couple issues. Get full list of history tapes working correctly. Check for valid range
+of CO2. New IC file interpolated from the previous one for f19_g17_gl4 for 2000 Clm50BgcCrop
+
+Update cime and cism so can work on upgraded hobart. Also fix an issue that the Nag6.2 compiler found
+in CTSM. Also get working with glade changes that happened on cheyenne, DIN_LOC_ROOT_CLMFORC was
+changed to a new directory.
+
+Nitrogen Fixation flux arrays were being set to missing value over non-vegetated landunits. This sets them to zero everywhere
+and averages in the zero's at the gridcell level for history output. It also reads in restarts with missing values and converts
+them to zero's.
+
+There are also some tools updates, getting the tools working on the new upgraded hobart.cgd.ucar.edu.
+
+And mksurfdata_map is updated to add some *_MAX files on the landuse.timeseries files that will allow us to conserve memory
+for transient cases.
+
+
+CTSM Master Tag This Corresponds To: ctsm1.0.dev004 (minus ctsm1.0.dev001)
+
+Summary of changes:
+-------------------
+
+Issues fixed (include CTSM Issue #): 
+
+   #210 -- increase number of history tapes
+   $427 -- Check for zero CO2
+   #429 -- New IC for present day
+   #441 -- Changes in glade invalidate previous softlinks and data locations
+   #438 -- Illegal argument aliasing caught by nag6.2
+   #433 -- with hobart upgrade CTSM not working
+   #435 -- intel build for tools
+   #426 -- Nitrogen Fixation flux variables
+   #433 -- hobart broken, got it working for tools
+
+Science changes since: release-clm5.0.03
+
+   Changes to Nitrogen fixation flux arrays so that they are zero everywhere and the zeros are averaged in for history output.
+   Answers change because of interpolated initial conditions for 2000 simulation year at f19_g17_gl4
+
+Software changes since: release-clm5.0.03
+
+   Get working on updated hobart. Add some new fields to mksurfdata_map tool.
+
+Changes to User Interface since: release-clm5.0.03
+
