The full tarballs for 1.8.3p8 are pennmush-1.8.3p8.tar.gz and
pennmush-1.8.3p8.tar.bz2.  The latter was compressed with pbzip2, a
parallel bzip2 implementation that can take advantage of multiple
CPUs/cores to speed up decompression. The file is compatible with
plain bzip2 as well. If you have pbzip2, decompress the tar file with
'pbzip2 -d FILENAME.tar.bz2', and extract it with 'tar xf
FILENAME.tar'. Otherwise, use 'tar xjf FILENAME.tar.bz2' to use bzip2.

There's also a version in zip format for Windows users.

The destination directory of the tarballs has changed: Instead of
unpacking into pennmush/, files go into pennmush-1.8.3p8/ so they do
not clobber an existing source tree.

1.8.3-patch08 is the patchfile to apply to existing 1.8.3p7 source
trees. 

A gzip-compressed versions of the patch file is included.  Download
it, uncompress them with gunzip, and follow the instructions at the
top of the patch file.

Also please note that the old 'patch -p1' invocation has changed to
'patch -p0'.

You can track PennMUSH via subversion, too:

svn checkout svn://svn.pennmush.org/svn/pennmush/1.8.3/tags/p8

If you already have a 1.8.3p7 tree checked out of subversion, update via:
svn merge svn://svn.pennmush.org/svn/pennmush/1.8.3/tags/p7 svn://svn.pennmush.org/svn/pennmush/1.8.3/tags/p8

You can also track up-to-the-minute fixes by checking out
svn://svn.pennmush.org/svn/pennmush/1.8.3/trunk and doing regular svn
updates. Tracking .../branches/devel instead of .../trunk gets you
(Potentially unstable) new features as well as fixes.

SHA1 checksums for the various files are in 1.8.3p8.checksums. There
is not yet a GPG signature for the tar file.
