Things are looking pretty good in this release. We'd love to make this the last release candidate before the official release of "FreeDOS 1.3." You can help make that happen by downloading FreeDOS 1.3 RC5 and testing all the programs! Let us know of any bugs or compatibility issues so we can fix them.
