+One-line Summary: Turn irrigation on for 2300 SSP extensions
+
+Purpose of this version:

+Issues fixed (include CTSM Issue #): #974 #972 #966
+  #974 -- Python3 problem in SSP test
+  #972 -- Irrigate is turned off for the 2300 extensions
+  #966 -- Units for a few history fields needs to change for ILAMB
+
+Science changes since: release-clm5.0.32
+  Irrigation is now properly turned on for the 2100-2300 SSP extensions
+  Change some units of history fields
