[Help-smalltalk] GNU Smalltalk 2.2d released

[Paolo Bonzini]

This should be the last release candidate for GNU Smalltalk 2.3.  In 
fact no change should be necessary between 2.2d and 2.3.

The release is available from:
ftp://alpha.gnu.org/gnu/smalltalk/smalltalk-2.2d.tar.gz

The changes from 2.2c are:

- An exception to the GPL is included in all the virtual machine's 
source files.  The exception allows Smalltalk programs to be combined 
with the virtual machine, and with any library bindings that bear the 
same exception, without the need to distribute the Smalltalk program 
under the GNU GPL too.  This of course does not invalidate any reason 
why the Smalltalk program would need to be distributed under the GNU GPL 
(including using GPLed class libraries, or dynamically linking GPLed 
libraries such as GNU readline).

- RegexResults objects are created from C code rather than Smalltalk 
code.  This should improve speed, even though it was done mostly for 
didactic reasons.

- C call-out do not necessarily create a new context.  This also causes 
performance improvements.

- Brad Watson's ncurses bindings are included.

- A severe bug in ObjectMemory class>>#quit: (latent since forever, but 
exposed recently) was fixed.

- A couple of packaging fixes, needed for Jochen Schmitt's Fedora RPMs.

Thanks to everybody who contributed to this release.
