FITS Software Libary Package - Version History

			Donald H. Gudehus

August, 2006 - Initial Version

September 2, 2006 - Prevented possible buffer overflow when entering file 
data format.  Improved scaling in saoload.for.

January 6-18, 2008 - Added ability for the output file to be the same as 
the input file for all cases.  One can now save to the same map after an
operation even if the size of the map is changed, and save to a new map
at the end of the same file, a different file, or a new file.  All of 
these choices also can be realized if one is looping over maps.  Previously
saving to the same map could only take place for simple updating of pixel
values.  Other changes are 1) the argument list in openfits.for has been
revised to reverse the order of NROWS and NCOLS, 2) FILENAME is now a
returned value in openfits.for, 3) the FITSFACTS common block is now an
include file, 4) the names of linepl.for, linepl1.for, and linepl2.for
were changed to linepl_fits.for, linepl1_fits.for, and line2_fits.for,
respectively, and 5) bugs in wrfitsmhst.for, where the value for the 
keyword XTENSION was sometimes getting corrupted, and where character
keywords were not getting written to multirecord headers, were fixed.

January 21, 2008 - Minor bug fix in save_save_as.for.

January 23, 2008 - Minor bug fixes.

January 24, 2008 - Minor compiler incompatibility fixes (as suggested by
Tobias Burnus)

January 26, 2008 - Added ability to work with FITS files in remote directories

January 28, 2008 - Improved the accuracy in wrfitsrow.for and wrfitsxy.for when
writing by taking the nearest integer for integer data types.

January 31, 2008 - Various minor fixes

February 6, 2008 - Various minor fixes

February 19, 2008 - In openfits.for, ensured that the number of rows and
columns would be returned when an old file was opened as a new file.

February 20, 2008 - Fixed bug in rwfitsxy.for which caused errors in writing
REAL*8 data under Linux.

February 21, 2008 - Fixed bug in the Mac version of save_save_as.for where the
prompt for saving was not operating correctly.  In open_temp_fits.for, NCOLS and
NROWS were made arrays so that several maps of differing sizes can be handled in
a loop.  Also, fixed a bug where IMNUM and IPNUM were being reset to 1 and 1 if 
openfits.fits was called in the case where the maps in the temporary file had
the same size as the maps in the input file.

March 24, 2008 - The library now includes an updated version of xyplot_ascii
which can plot data from one or more ASCII files.

April 2, 2009 - Fixed bug in xyplot.for where interactive command "v" was not
working properly.

April 14, 2009 - Fixed bug in sao_vect.for which was introduced in a previous

May 12, 2009 - Minor wording changes in testfits.for, wrfitsmhst.for, and 
wrfitsmhv.for.

oriented when more than 2 plots were written to a plot file.

September 23, 2013 - Updated code to allow for operation on 64-bit Intel systems
