NetBSD 8.0 RC1 is available now

Mr Martin Husemann on behalf of NetBSD project has announced the availability of NetBSD 8.0 RC1, first release candidate for upcoming NetBSD 8.0 stable release. NetBSD is an independently developed, BSD like operating system that support a wide variety of architectures.

NetBSD 8.0 RC1 being a development release is most likely to contain bugs and stability issues, hence it is not recommended to use in production systems. The main audience of a release candidate is the community testers and curious users who are eager to see the new features. This release candidate will give a clear idea on what we can expect from the final release.
