The Tcl 7.6 and Tk 4.2 releases

This page contains information about Tcl 7.6 and Tk4.2,
 which are the most recent
releases of the Tcl scripting language and the Tk toolk
it. The first beta versions of these
releases were released on August 30, 1996. These releas
es contain only minor changes,
so we hope to have only a single beta release and to 
go final in early October, 1996.


What's new 

The most important changes in the releases are summariz
ed below. See the README
and changes files in the distributions for more complet
e information on what has
changed, including both feature changes and bug fixes. 

     There are new options to the file command for 
copying files (file copy),
     deleting files and directories (file delete), 
creating directories (file
     mkdir), and renaming files (file rename). 
     The implementation of exec has been improved great
ly for Windows 95 and
     Windows NT. 
     There is a new memory allocator for the Macintosh 
version, which should be
     more efficient than the old one. 
     Tk's grid geometry manager has been completely 
rewritten. The layout
     algorithm produces much better layouts than before
, especially where rows or
     columns were stretchable. 
     There are new commands for creating common dialog 
boxes:
     tk_chooseColor, tk_getOpenFile, tk_getSaveFile and
     tk_messageBox. These use native dialog boxes if 
they are available.
     There is a new virtual event mechanism for handlin
g events in a more portable
     way. See the new command event. It also allows 
events (both physical and
     virtual) to be generated dynamically. 

Tcl 7.6 and Tk 4.2 are backwards-compatible with Tcl 
7.5 and Tk 4.1 except for
changes in the C APIs for custom channel drivers. Scrip
ts written for earlier releases
should work on these new releases as well. 

Obtaining The Releases

Binary Releases

Pre-compiled releases are available for the following 
platforms:

     Windows 3.1, Windows 95, and Windows NT: Fetch
     ftp://ftp.sunlabs.com/pub/tcl/win42b1.exe, then 
execute it. The file is a
     self-extracting executable. It will install the 
Tcl and Tk libraries, the wish and
     tclsh programs, and documentation. 
     Macintosh (both 68K and PowerPC): Fetch
     ftp://ftp.sunlabs.com/pub/tcl/mactk4.2b1.sea.hqx. 
The file is in binhex format,
     which is understood by Fetch, StuffIt, and many 
other Mac utilities. The
     unpacked file is a self-installing executable: 
double-click on it and it will create a
     folder containing all that you need to run Tcl 
and Tk.
        UNIX (Solaris 2.* and SunOS, other systems 
soon to follow). Easy to install
     binary packages are now for sale at the Sun Labs
