Plan 9 transferred to the Plan 9 Foundation

The funky second OS from the Unix masterminds, Plan 9, has been fully transferred to the Plan 9 Foundation, and it’s been released under the MIT license.

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.

The historical releases are at the Foundation’s website. Nokia also posted a press release which gives some more background about Plan 9 for those who may not know about its history.
