The big change this cycle is the C compiler, which has now reached
the point of being useful.  We now need lots of volunteers to help
flesh out the C library, pnetC, to include all of the usual libc
features.  I'd also like to encourage everyone to try to port their
favourite Free Software libraries and applications, and report any
problems that are found.

There have also been a lot of bug fixes and performance improvements
in System.Windows.Forms, thanks to Neil Cawse.  And Richard Baumann
has completely rewritten the System.Xml parser, fixing many long-standing
issues with the XML library.

The "ml-pnet" package is a re-release of ml-pnet-0.6.2 with a new
version number, because there have been a lot of changes to Mono
recently and it is difficult to keep track of them all.  We need a
volunteer to maintain ml-pnet on a more regular basis.

Signed MD5 sums for the above files are appended to this message.

Cheers,

Rhys.
