Apple Discontinues ZFS Project26 Oct 2009
Apple has replaced its ZFS project page with a notice that 'The ZFS project has been discontinued.
All signs point to licensing issues being the primary reason for Apple to cease development on the project. It is an unfortunate loss because ZFS was one of the more promising things I wanted to see included in MacOS X. Some have pointed out that <a href="http://devwhy.blogspot.com/2009/10/loss-of-zfs.html>all is not lost</a> because Apple may replace HFS with an even better alternative than ZFS might have been.
