It's not the biggest of releases, but progress is progress at this point. Since launching in late April, Microsoft has been rather mum on the future of its latest Windows Home Server build. This week, however, the second major beta release has been let loose into the wilds, with Vail's most recent build now available to download there in the source link. The Big M doesn't go into great detail on what all has been added and / or changed, only saying that this new version has "plenty of enhancements and improvements over the original." The so-called "Preview" also adds support for Mac OS X backups, though users should know that storage check and repair (among other things, most likely) aren't exactly working seamlessly.
