    4. 01.03.2003 XPA: fixed a problem with 'xpaget ds9 regions selected'
    5. 01.28.2003 SAVEAS: now saves all slices of a data cube, if the display mode is single.
    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.
    17. 02.25.03 XPA: fixed a bug with loading an image from xpa stdin without a filename.
    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
    23. 02.27.03 HV: fixed some problems with tkhtml uri resolver. This cleans up a lot of tcl code.
    24. 03.04.03 HV: images are now scaled if the width/height args are provided in the html src.
    25. 03.04.03 ARCHIVE: add chandra archive web chaser.
    26. 03.12.03 COLORMAP: Fixed a problem with InitColorbar and a colormap of A or B.
    27. 03.12.03 ANALYSIS: all comments after # are ignored.
    28. 03.12.03 ANALYSIS: non macros can be escaped by using $$.
    29. 03.31.03 COMMAND: Add -frame command line option.
    30. 04.08.03 GUI: Remove Magnifier Mode option, along with Magnifier Replicate code.
    31. 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.
    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>
    33. 05.12.03 API: *** CHANGE *** shared memory loads no longer require the size of the memory segment.

    35. 05.20.03 AST: update to 2.0
    36. 05.22.03 GRID: fix a problem with grid.C interface to AST. The text bounding box code was returning the coordinates in a clockwise manner. It needs to be returned in an anti-clockwise manner.
    37. 05.22.03 GRID: Add support for user specified Grid Axes Numerics gap.
    38. 05.27.03 GRID: Fixed a problem with the bounding box of a publication grid. it was .5 pixels off.
    39. 05.28.03 GUI: Fixed a problem with 'get cursor'. Sometimes, as with loading dss images, the matrices were not updated in time, and 'get cursor' returned bogus values. Now all calls to 'get cursor' force an update.
    40. 06.02.03 GUI: fixed several problems with examine mode
    41. 06.02.03 ARCHIVE: add NOAO 4MASS and SIRTF and NOAO NSA to archive menu

    50. 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.
    51. 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.
    52. 06.26.03 FITS: Add support 3D array data cubes.
    53. 06.30.03 RGB: Add support for RGB array data cube.
    54. 07.01.03 DSS: Fixed namesrv.tcl and dss.tcl to promote more robust error handling. In particular, http error codes are now checked, and the results are verified before proceeding

    62. 07.11.03 XPA: add DATACUBE support.
    63. 07.14.03 WCS: Fixed a problem with WCS XLON-TAN (NPOLE) and AST. NPOLE is a special wcs equ coord system, and has to be handed by wcs2ast().
    64. 07.15.03 XPA: add xpa iis access port for control of some iis functionality.

    65. 07.17.03 RELEASE version 3.0b4

    77. 08.19.03 XPA: add options to xpa update so that 'update idletasks' is not run at the end of file loads. This allows the user to do several incremental loads without updating the screen.
    78. 08.19.03 API: only update idletasks for horz/vert graph if graphs are on
    79. 08.19.03 API: add debug idletasks support.

    160. 02.01.04 WCS: more on #50 and #141. If wcs projection is Zenithal, use CRPIX as reference point to determine wcs rotation and oriention. Otherwise, use image center point.
    161. 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.
    162. 02.04.04 CONTOUR: A .5 error has been removed from the BLOCK algorithm.
    163. 02.04.04 CONTOUR: the number of contour levels has been inconsistant in the pass. this has been fixed. If the number of levels is 1, the high cut value is used.
