The most recent Hugs release was in November 2002, and several bug fixes and improvements have been made in the development version since then. I'd like to appeal for testers willing to build and test a snapshot of the sources (Unix only, unfortunately, I don't know how to build on Windows), to help iron out the bugs, hopefully moving towards a release. To try it out, download http://www.soi.city.ac.uk/~ross/hugs98-Aug2003.tar.gz unpack it, and then cd hugs98-Aug2003/src/unix ./configure cd .. make install This installs in /usr/local -- to install at home, add --prefix=$HOME to the configure line. Please report bugs to hugs-bugs@haskell.org
