"NetBSD is currently 0.1, with lots of patches applied. … It, like 386BSD, is intended to be used for research.Some could look at NetBSD as simply an interim release of 386BSD. We look it as more, and therefore have named it differently. The new name and version number reflect two of our goals for NetBSD: an escape from the political wars surrounding what we consider a wonderful operating system, and the rapid development of a stable release which we would consider of "production quality." …We intend to integrate free, positive changes from whatever sources will provide them, providing that they are well thought-out and increase the usability of the system. This includes integrating changes from 386BSD 0.2 when it appears, as well as from , and perhaps even going back to in order to re-integrate support for other architectures ….Above all, we hope to create a stable and accessible system, and to be responsive to the needs and desires of NetBSD users, because it is for and because of them that NetBSD exists."
