We are thrilled to announce that Nokia has transferred the copyright of Plan 9 to the Plan 9 Foundation. This transfer applies to all of the Plan 9 from Bell Labs code, from the earliest days through their final release.

The most exciting immediate effect of this is that the Plan 9 Foundation is making the historical 1st through 4th editions of Plan 9 available under the terms of the MIT license. These are the releases as they existed at the time, with minimal changes to reflect the above.

    Hopefully there’ll be some new life to plan9 and its derivatives now.

    There’s far too many people out there that somehow believe UNIX is the final OS design. The more the counterexamples, the better.
