+August 15, 2000: VIC release 4.0.3
+
+This release fixes a problem with the implementation of va_arg that 
+causes run time errors on some systems.  Previous releases of the code 
+worked correctly on the LINUX and freeBSD systems where it was tested. 
+However on some systems (including Sun Ultra-2s) character variables 
+passed with va_arg are changed into integers so reading a character from 
+the argument list does not produce the value sent to the routine.  The
+character flags used by VIC to indicate if there is snow present and if
+the frozen soil algorithm has been activated have now been converted to 
+integers, which should make the va_arg call work on all systems.
+
+Also fixed in this release was a check in dist_prec.c to see if it is 
+still raining which actually used the memory address of the 
+precipitation variable rather than the daily value in the check.
+
+MODIFIED FILES:
+	read_atmos_data.c	-	Fixed input file time step check
+	write_forcing_files.c	-	Added free statements for pointers
+	calc_surf_energy_bal.c	-	Converted char flags to int
+	dist_prec.c		-	Fixed logical statement error
+	frozen_soil.c		-	Converted char flags to int
+	func_surf_energy_bal.c	-	Converted char flags to int
+	initialize_atmos.c	-	Added flag for output forcing
+	vicNl.h			-	Converted char flags to int
+	vicNl_def.h		-	Converted char flags to int
+
+July 19, 2000: VIC release 4.0.2
+
+Two new pre-processor options have been added to VIC as well as minor 
+modifications to two subroutines.  
+
+If set to TRUE the NO_REWIND pre-processor option stops the VIC model from
+rewinding the soil and vegetation parameter input files for each new grid
+cell.  This reduces run times but requires that all input files are in the
+same order as the soil parameter file.  
+
+If set TRUE the OUTPUT_FORCE pre-processor option blocks off the main
+model and only reads the provided forcing files. Once VIC has estimated
+the missing forcing parameters the full forcing data set for the defined
+simulation period is output to a series of gridded forcing files.  The
+gridded forcing files are written to the RESULTS directory defined in the
+global control file with the prefix "full_data_".  The new files are in
+Binary or ASCII depending on the setting of BINARY_OUTPUT.
+
+The error messages in get_global_param.c have been modified so that the
+correct file is referenced when telling the user to change values found in
+the model source code.
+
+In read_soilparam.c, the soil parameters are defined only if the current
+grid cell is run, otherwise the line in the file is skipped and soil_con
+is retruned without new data values.
+
+May 30, 2000: VIC release 4.0.1
+
+Increased use of the released VIC model code has lead to the
+discovery of a couple of minor bugs.  This release fixes those bugs as
+well as introducing a improved precipitation correction algorithm based on 
+Yang et al. 1998.  Unless you have encountered these problems or are
+trying to correct precipitation undercatch due to wind, in the VIC
+model, your results will not be impacted by these fixes.
+
+MODIFIED FILES:

+                             NWS 8" standard gauge.
+    full_energy.c          - modified to handle WMO correction.
+    initialize_atmos.c     - modified to handle WMO correction.
+                             fixed error in estimating minimum daily 
+                             temperature from sub-daily temperatures.
+    make_in_and_outfiles.c - removed line that opened the state file
+                             again for each new grid cell.
+    open_state_file.c      - modified comments.
+    put_data.c             - modified to handle WMO correction.

+
+Topic: Release of VIC 4.0.0
+
+The code for VIC release 4.0.0 has undergone several months of tests (as
+VIC release 3.3.0 Beta) and has now been deemed ready for release to the
+general public.  This document is designed to provide information
+concerning changes in the model between the last release version (3.2.1)
+and the current version.
+
+There is no formal users manual, information about how to use the current
+version can be found at
+http://www.hydro.washington.edu/Lettenmaier/Models/VIC/VIChome.html.  
+Information about the basic model design can be found in Liang, et al.
+(1994), while the rewrite of the source code as well as the addition of
+cold season processes is described in Cherkauer and Lettenmaier (1999).
+
+The VIC macroscale hydrologic model was developed as a research tool.  As
+such it is the users responsibility to verify that it is working correctly
+when applied to new situations.  When using the VIC model reference should
+be made to Liang, et al. (1994) and Cherkauer and Lettenmaier (1999) as
+well as an acknowledgment that the code was received from the University
+of Washington.  Other important papers relating to the development of the
+VIC model are included on the home page and in the source code.
+
+Possible bugs in the code should be reported to
+vicadmin@hydro.washington.edu.  ALWAYS CHECK YOUR INPUT FILES!  Most
+"bugs" are actually caused by trying to run the model with bad parameters
+or forcing data.  The VIC model will run limited checks to find common
+major errors but in most cases it will attempt to run with the bad values.  
+If after checking all of your input data you still believe you have found
+a bug in the model, send an e-mail including the complete output from the
+model as well as a description of the problem and the files necessary to
+run the model to recreate the code (if files are large please put a
+compressed tar file in
+ftp://ftp.ce.washington.edu/pub/HYDRO/vicadmin/TEMP).  Outdated and
+modified versions of the code are the responsibility of the user to debug.  
+Modifications made to the code, which may improve the general model
+performance, may be submitted to vicadmin@hydro.washington.edu for
+possible inclusion in future versions of the code.
+
+VIC release 4.0.0 represents a major change to the source code from
+version 3.2.1.  It is strongly recommended that if you were using version
+3.2.1 or earlier versions that you update with a complete copy of the new
+code.
+
+Major changes from release version 3.2.1 to 4.0.0:
+
+- Radiation Estimation Update: The routines to estimate shortwave and
+longwave radiation as well as vapor pressure from daily minimum and
+maximum temperature and precipitation have been updated to correspond to
+the algorithm described by Thornton and Running (1999).  These routines
+provide significantly improved radiation estimates especially in regions
+outside the continental United States.
+
+- Model Core Update: The core of the VIC model was rewritten so that all
+modes of the model (water balance, energy balance, etc.) make use of the
+same model code.  This makes it easier to modify the model and have
+modifications apply to sll modes, it also allows the model to run with new
+combinations of algorithms (i.e. full energy balance mode with the finite
+difference ground heat flux solution).
+
+- Soil Moisture Transport Update: The frozen and thawed sub-layers added
+to the model for the original frozen soil algorithm have been removed.  
+This makes the soil drainage routine cleaner and faster.  Frozen soils now
+estimate full layer ice contents from the ice content at each soil thermal
+node.  Without being confined by sub-layers, the frozen soil algorithm can
+now be applied to regions of permafrost.
+
+- Forcing File Control Added: Version 4.0.0 moves controls of the forcing
+file format and data types into the global control file.  The model can
+now handle most ASCII column and short int Binary files without writing
+new subroutines and recompiling the source code.
+
+- Pre-processor Options Added: There are now more option flags in the
+source code headers to control which parts of the model are in fact
+compiled.  This allows the model functionality to be adjusted without the
+addition of computationally intensive conditional switching statements.
+
+- Model State File: With the release of version 4.0.0 separate snow and
+soil initialization files have been combined into a single model state
+file.  The state file can be created outside the model for starting
+simulations with prescribed initial conditions, or the model state can be
+saved by VIC at a specified date.  Note that currently there will be small
+differences between a full and a warm started simulation because radiation
+and vapor pressure are estimated using forcing data from the simulation
+period, not from the full dataset included in the forcing file.  It also
+does not store wet and dry fraction information, when running with
+distributed precipitation the model is restarted using average soil
+conditions.
