+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 
+Tcl/Tk Shop. Check it out!
