Subject: Tcl 8.0 and Tk 8.0 releases
Newsgroups: comp.lang.tcl.announce
Followup-To: comp.lang.tcl

This message is to announce the 8.0 releases of the Tcl scripting
language and the Tk toolkit.  These are major releases with many
exciting new features, including the following:

- Tcl has a new bytecode compiler that improves performance by a factor
  of 2-10x.
- Tcl now has namespaces for structuring variables and procedures.
- Binary data is now supported in Tcl.
- The Safe-Tcl security model has been fleshed out and improved in
  many ways.  It provides the most flexible approach to security for
  Internet applications available anywhere.
- The Windows registry is now supported.
- A package "http" is available for making HTTP requests.
- Tk now provides native look and feel on Macintosh and Windows platforms.
  Tcl and Tk now provide one of the best cross-platform development platforms
  available anywhere.
- Fonts and menus have been improved to provide much better cross-platform
  support.
- Text widgets allow images to be embedded directly in the text.

There are a few incompatibilities introduced by these releases (hence the
change in major version number) but they are small and should not affect
most scripts.  See the Tcl/Tk 8.0 Web page for more information on both
the new features and the incompatibilities:
