August 21, 2007 - Version 1.2.10
--------------------------------
Minor bug fixes.  It now works on Solaris.  We now disable all titles 
and footnotes at initialization; previous behavior was to go with SAS's
default, causing problems if you disable titles and such.  Unlike
previous versions, if you have a title statement, now it will show.


June 14, 2007 - Version 1.2.9
-----------------------------
No changes at all to the scripts.  Only change is the manual, which 
now has a table of contents and an index.


June 8, 2007 - Version 1.2.8
----------------------------
Windows scripts changed to work around NASTY incompatibilities among
various gawk implementations.  No changes to unix version.  


June 4, 2007 - Version 1.2.7
----------------------------
Minor bug fix on post-processing routine


June 1, 2007 - Version 1.2.6
----------------------------
Added one significant capability -- ability to split-up IML code
into more than one code chunk.  Also added three options: codesize,
outsize, and squeeze.


May 30, 2007 - Version 1.2.5
----------------------------
Minor change to the way files are named.  This brings it more
in line with Sweave in that if a label is provided, it is used in
place of the chunk number as a suffix for any graphics or split
files produced by a code chunk.

Our submission to Journal of Statistical software has been accepted
subject to minor revisions; we have replaced the earlier manual 
previously posted on this site with the revised JSS paper.


Apr. 20, 2007 - Version 1.2.4
-----------------------------
Minor bug corrections (see file CHANGES.txt in download package).
Windows installed revised to require Gawk.exe to be installed
separately beforehand.  This is necessary to ensure that user has
a running version of Gawk and that it doesn't conflict with
other applications installed on the system.  Windows associations
were shifted to current user only, thus allowing a non-Administrator
install.  Also added separate icons and actions for Sweave files.


Feb. 14, 2007 - Version 1.2.3
-----------------------------
SASweave.sty is renamed SasWeave.sty -- prevents a conflict
with Sweave (which searches for the string "Sweave}" in preamble)


Feb 13, 2007 - Version 1.2.2
----------------------------
Now uses its own LaTeX package (SASweave.sty) rather than
using Sweave.sty

Options inputsize and outputsize deprecated in favor of more
flexible codefmt and outfmt.



Feb 5, 2007 - Version 1.2.1
----------------------------
New options fig, figdir, infigdir, split, and and prefix.string.  

Enhancement to fig option so now you can get multiple figures with
one code chunk (e.g. options {fig=3, plotname=\myplot} allows for 3
figures, and defines macros \myplotA, \myplotB, and \myplotC (as
well as \myplot, which is the same as \myplotA).

Bug fixes: SAS macros now work; multiple \usepackage{Sweave}
commands are no longer generated; formchar option added in default
setup so that tables and lineprinter plots look better. 



Dec 19, 2006 - Version 1.2.0
----------------------------
Support is now included for source files that contain both SAS and R
code.  In fact, you can use SASweave instead of Sweave to process
Sweave source files.

The lengthy shell scripts for each OS are replaced by a single awk script
that works on both, and very short shell scripts to set them up.  

The Windows version is provided via an installer that leads you through 
the process and is (or seems to be) able to find the locations of SAS, 
pdflatex, and R.  It will install the required program gawk.exe if
needed, but it will use your existing gawk if found in your search path.
The installer also (at your option) sets up associations so that you
can weave or tangle codes using the right-button menu in Windows
Explorer.



Nov 22, 2006 - version 1.11
----------------------------
Windows scripts changed: previous use of " characters interfered with
processing when directory or file name contained spaces.



Nov 21, 2006 - version 1.1
--------------------------
There is now an updated version from the original one posted on November 17.
New capabilities include the addition of sastangle, being more forgiving
with whitespace, allowing continuation lines for options, and argument
substitution in reusable code.



Nov 17, 2006 - version 1.0
