+ <li> <tt>01.03.2003 XPA: fixed a problem with 'xpaget ds9 regions
+selected'</tt></li>
+ <li><tt>01.28.2003 SAVEAS: now saves all slices of a data cube, if
+the display mode is single.</tt></li>
+ <li><tt>01.28.2003 GUI: Add 'wm protocol . WM_DELETE_WINDOW
+QuitDS9' for main window so that tcl/tk 8.4 does not segv when a user
+double clicks on a close window icon.</tt></li>
+ <li><tt>01.29.2003 GCC: add support for gcc 3.0/3.2</tt></li>
+ <li><tt>01.29.2002 GCC: updated saotk/FlexLexer.h from flex 2.5.27,
+available at http://lex.sourceforge.net/<br>
+ </tt></li>
+ <li><tt>02.04.2003 WINDOWS: modify configuration files for tkimg1.3
+and tkhtml to support windows.<br>
+ </tt></li>
+ <li><tt>02.05.2003 WCS: upgrade to 3.3.0</tt></li>
+ <li><tt>02.06.2003 ARCHIVE: the default ADS max search size is now
+a radius of .1
+arcmin.</tt></li>
+ <li><tt>02.06.2003 XPA: add '-xpa tcl' command line option. By
+default, disable xpa tcl access since it is a major security risk.</tt></li>
+ <li><tt>02.07.03 FITS: fixed a problem with loading fits files via
+the url menu or command line.<br>
+ </tt></li>
+ <li><tt>02.07.03 HTTP: loading images via url http processes the
+image based on the http header mime type and encoding, not the file
+name. images loaded via url ftp are still processed based on file name.</tt></li>
+ <li><tt>02.07.03 PLOT: fixed a problem with global vars and the
+plot widget.</tt></li>
+ <li><tt>02.11.03 BINNING: fixed a bug with the bin table smoothing
+support. If the bin factor is large enough to bin the entire image in
+the bin buffer, ds9 would segv by trying to read out of bounds.</tt></li>
+ <li><tt>02.25.03 XPA: fixed a bug with loading an image from xpa
+stdin without a filename.</tt></li>
+ <li><tt>02.25.03 XPA: add 'fillbuf=false' to all xpa receive
+commands that do not use $buf. This will speed up processing because
+the data socket is not opened.</tt></li>
+ <li><tt>02.25.03 XPA: fixed a problem with appending an wcs via
+xpa. The appended wcs is now positioned at the end, not the beginning.
+also, a problem occurred when the 'END' card was not the last card of
+the header. This has been fixed.</tt></li>
+ <li><tt>02.25.03 XPA: changes to xpa regions syntax.
+'moveback'/'movefront' are now 'move back'/'move front',
+'selectall'/'selectnone' are now 'select all'/'select none', and
+'deleteall' is 'delete all'. Backward compatibility has
+bee maintained</tt></li>
+ <li><tt>02.25.03 XPA: add 'select group &lt;groupname&gt;' and
+'delete select' to xpa regions access point.</tt></li>
+ <li><tt>02.26.03 HV: add support for gif,png,ppm,xbm,xpm file
+formats</tt></li>
+ <li><tt>02.27.03 </tt><tt>HV: </tt><tt>fixed some problems with
+tkhtml uri resolver. This cleans up a lot of tcl code.</tt></li>
+ <li><tt>03.04.03 HV: images are now scaled if the width/height args
+are provided in the html src.</tt></li>
+ <li><tt>03.04.03 ARCHIVE: add chandra archive web chaser.</tt></li>
+ <li><tt>03.12.03 COLORMAP: Fixed a problem with InitColorbar and a

+ <li><tt>03.31.03 COMMAND: Add -frame command line option.</tt></li>
+ <li><tt>04.08.03 GUI: Remove Magnifier Mode option, along with
+Magnifier Replicate code.</tt></li>
+ <li><tt>04.23.03 HST WFPC: Mosaic images must be loaded directly.
+this fixes a problem in that it was not possible to autodect a WFPC2
+image in an incoming data stream, such as stdin.</tt></li>
+ <li><tt>05.12.03 API: *** CHANGE *** Frame load syntax has changed
+to make it consistent across all modes and file formats. In particular,
+the general syntax is: &lt;frame&gt; load fits|array &lt;filename&gt;
+mmap|alloc|alloc gz|channel|shared|socket|var &lt;options&gt;</tt></li>
+ <li><tt>05.12.03 API: *** CHANGE *** shared memory loads no longer
+require the size of the memory segment.</tt></li>
+ <li><tt>05.20.03 WCS: update to 3.3.4</tt></li>
+ <li><tt>05.20.03 AST: update to 2.0</tt></li>
+ <li><tt>05.22.03 GRID: fix a problem with grid.C interface to AST.

+Numerics gap.</tt></li>
+ <li><tt>05.27.03 GRID: Fixed a problem with the bounding box of a
+publication grid. it was .5 pixels off.</tt></li>
+ <li><tt>05.28.03 GUI: Fixed a problem with 'get cursor'. Sometimes,
+as with loading dss images, the

+values. Now all calls to 'get cursor' force an update.</tt></li>
+ <li><tt>06.02.03 GUI: fixed several problems with examine mode</tt></li>
+ <li><tt>06.02.03 ARCHIVE: add NOAO 4MASS and SIRTF and NOAO NSA to
+archive menu</tt></li>

+coordinates and save/load regions.</tt></li>
+ <li><tt>06.18.03 WCS: fix a problem with determining the rotation
+of a wcs coordinate system. previously, CRPIX was used as the start
+point. This does not work in cases where the tangent point is very far
+off the image. Instead, (1,1) is used.</tt></li>
+ <li><tt>06.18.03 WCS: Remove preference Panner WCS origin. This is
+stupid and breaks with the previous change. Just remove it instead of
+trying to fix it.</tt></li>
+ <li><tt>06.26.03 FITS: Add support 3D array data cubes.</tt></li>
+ <li><tt>06.30.03 RGB: Add support for RGB array data cube.</tt></li>

+still restricted to ~2.5Gb.</tt></li>
+ <li><tt>07.10.03 FITS: add FLUSH parameter for fitsy++ array.</tt></li>
+ <li><tt>07.10.03 FITS: Major change in behavior of fitsy++ streams
+and FLUSH. Only socket and socketgz will flush, all others will not
+flush the buffer after
+an error, or after successfull loading a fits image.</tt></li>
+ <li><tt>07.11.03 XPA: add DATACUBE support.</tt></li>
+ <li><tt>07.14.03 WCS: Fixed a problem with WCS XLON-TAN (NPOLE) and

+script of mktclapp. The first sees that the the virtual file system is

+oriention. Otherwise, use image center point.</tt></li>
+ <li><tt>02.04.04 CONTOUR: modified smooth algorithm. We now SMOOTH
+the entire image with a gaussian kernal. Previously, we would block by
+2 before smoothing with a boxcar kernal. Finally, the default method is
+BLOCK.</tt></li>

+from the BLOCK algorithm.</tt></li>
+ <li><tt>02.04.04 CONTOUR: </tt><tt>the number of contour levels
