6. `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.`
7. `01.29.2003 GCC: add support for gcc 3.0/3.2`
8. `01.29.2002 GCC: updated saotk/FlexLexer.h from flex 2.5.27, available at http://lex.sourceforge.net/
   `
9. `02.04.2003 WINDOWS: modify configuration files for tkimg1.3 and tkhtml to support windows.
   `
10. `02.05.2003 WCS: upgrade to 3.3.0`
11. `02.06.2003 ARCHIVE: the default ADS max search size is now a radius of .1 arcmin.`
12. `02.06.2003 XPA: add '-xpa tcl' command line option. By default, disable xpa tcl access since it is a major security risk.`
13. `02.07.03 FITS: fixed a problem with loading fits files via the url menu or command line.
    `
14. `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.`
15. `02.07.03 PLOT: fixed a problem with global vars and the plot widget.`
16. `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.`

18. `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.`
19. `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.`
20. `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`
21. `02.25.03 XPA: add 'select group <groupname>' and 'delete select' to xpa regions access point.`
22. `02.26.03 HV: add support for gif,png,ppm,xbm,xpm file formats`

29. `03.31.03 COMMAND: Add -frame command line option.`
30. `04.08.03 GUI: Remove Magnifier Mode option, along with Magnifier Replicate code.`

32. `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: <frame> load fits|array <filename> mmap|alloc|alloc gz|channel|shared|socket|var <options>`

38. `05.27.03 GRID: Fixed a problem with the bounding box of a publication grid. it was .5 pixels off.`
