There are three key new features in 8.1 that establish Tcl as the leader
among scripting languages, making it the industry's first scripting
solution capable of handling enterprise-scale application integration
tasks. No other cross-platform scripting language has all of these key
features:
* Full Unicode support and a message catalog for internationalization.
* Thread-safety for Tcl and Tk.
* A new regular expression package by Henry Spencer that adds many
advanced features: non-greedy quantifiers, bounds, positive
and negative lookahead, collating elements, equivalence classes,
several built-in character classes, and comments. In addition,
the regular expression engine works on Unicode strings to make
this the best regular expression package available anywhere.

Bugs fixed since the 8.1b3 release:
-----------------------------------
There were only a few critical changes made since the last beta:
* Fixed a deadlock in the notifier that had caused focus.test to hang.
* Fixed bug where socket -async combined with fileevent for writing
did not work under Windows NT.
* Restored the double byte definition of GB2312 and added the EUC-CN
encoding. EUC-CN is a variant of GB2312 that shifts the characters
into bytes with the high bit set and includes ASCII as a subset.
* Added 'extern "C" {}' block around the stub table pointer declaration
so the stub library can be used from C++.
* Set the -translation and -encoding options to binary for image files.
* Fixed a memory leak in "info complete" with long, incomplete commands.
