Here is what I posted to our mailing list about the release:
The new release of Aleph One is available at our sourceforge page!
http://sf.net/projects/marathon
The biggest feature for this release is the Find Internet Game server,
which will bring players together from all over the world. If you're
still using AIM or IRC to find games, it's time to switch. Just start up
the new Aleph One, click "Join Network Game", then "Find Internet Game".
Or, if you want to gather, Gather Network Game, and make sure the
"Advertise Game on Internet" checkbox is checked.
Be sure to try out the new in-game chat (type backslash to activate, and
enter to send), and get ready for scenarios and net scripts to start
using new Lua functionality.
The new version also comes with lots of bug fixes. You can read the full
