openMSX 18.0—Lucky Number—is again a release with mostly bug fixes and smaller improvements. And of course a little more blasphemy out there adding support for Sega SG-1000. Together with openMSX an updated version of Catapult, our user-friendly GUI, was released, but there were no functional changes this time. Please read the release notes for details of the openMSX changes. Special thanks to all the contributors of this release who are not in the core team! Keep these pull requests coming!
