I'm unable to get MH-E 8.3 to build in the package tree. See
http://list-archive.xemacs.org/pipermail/xemacs-beta/2013-January/023770.html
for a description of the build problem. This is not an issue that the
upstream devs are familiar with, and my Lisp skills are inadequate for
figuring this out. Since this breaks the build, I am ceasing work on
this bug.
If anyone else would like to take over the bug, feel free to ask me for
the patches that I've accumulated so far.
The current mh-e package is 7.4.2. The latest upstream
version is 8.0.3. It has a variety of improvements; the one I
notice most often is improved search facilities.
