                 VLT-SW-APR2004 - RELEASE NOTES FOR TCL/TK
                 =========================================

   The Tcl/Tk included with the VLT Common Software APR2004 release
   contains the following extensions, which are upgraded with respect
   to APR2003 as indicated:
        - Tcl/Tk 8.4.5     (updated from 8.3.5)
        - [incr Tcl] 3.3   (updated from 3.2.1)
        - iwidgets 4.0.2   (updated from 4.0.1)
        - TclX/TkX 8.4     (updated from 8.3.5)
        - BLT 2.4z
        - msqltcl 1.99     (modified to work with msql 2.x)
        - tkimg 1.3        (updated from 1.2.4)
        - Tktable 2.8
        - snack 2.2.1      (updated from 2.2)
        - expect 5.38
	- tcllib 1.3
        - tkman 2.2        (updated from 2.1)
        - Sybtcl
   Several of these extensions have been patched to deal with known
   problems.

   The VLT APR2004 release also provides the following Tcl/Tk based 
   utilities:
        - tclCheck 1.1.13
        - TclPro 1.5 (for HP-UX, Solaris and Linux)

   Changes (with respect to APR2003):
     - several newer versions (see above)
     - with Tk 8.4, a Tk-internal command "panedwindow" was
       introduced, which unfortunately conflicts with the iwidgets'
       "panedwindow" command. To avoid this conflict, we have renamed
       the iwidgets' version into "ipanedwindow". In other words,
       applications using this widget should apply the same renaming
       (although it is recommended on the long term to port 
       applications to use the Tk-version of that widget).

   New Features (with respect to APR2003):
     - as part of the new releases (see the individual manpages)
