2011-12-01: The Hatari project is moving to tuxfamily.org

Since the future of BerliOS is still unclear, we decided to move the Hatari project now to a new host. Starting with today, Hatari will now be hosted on tuxfamily.org. Our new homepage is http://hatari.tuxfamily.org/ – so please update your bookmarks!

Information about downloading Hatari releases and about how to clone the new Mercurial repository can be found here: http://hatari.tuxfamily.org/download.html

Of course we will also need a new mailing list since the list at BerliOS might not survive in 2012. Please visit the following page for information about how to join the new mailing lists: http://hatari.tuxfamily.org/contact.html

Please have a look at the new website, test the new mercurial repository, join the new mailing list(s) and if you hit a problem, get in touch with us.
