This version has two major improvements : it's able to index mail messages with content held in a file outside the mbox, and to get the system's battery status via DeviceKit-power or upower.
Several bugs were fixed (including Debian bug #556062). I would encourage anyone using an 0.9x release to upgrade to this.
Note that if you have Xapian 1.2.0 or newer installed, Pinot will use its new smaller, faster Chert back-end.
Special thanks go to Jens Wilhelm Wulf for his feedback and patience ;-)
