ExpanDrive

Amit Singh at Google has released MacFUSE 1.5 into the wild, with a variety of changes and bug fixes. ExpanDrive uses the MacFUSE library to interface with the Mac filesystem, and the next reversion of ExpanDrive will integrate this revision. In addition, we’ll provide some more transparent facilities for users to uninstall MacFUSE if they desire.

For ExpanDrive, the most notable bug fix in MacFUSE 1.5 addresses the problem where ExpanDrive would occasionally show a mounted drive as having 0KB of free space, effectively disallowing writes to the volume.
