 -autopkgtest (0.8.1feisty1~iwj2) feisty-updates; urgency=low
++autopkgtest (0.8.2) gutsy; urgency=low
+ 
+   * Fix fd handling to work around Python's habit of closing files
+     you specify in subprocess.Popen.
+   * Error handling bugfixes: say except (IOError,OSError) everywhere
+     rather than just one of those two; correct harmless bug in gpg key
+     generation error handling.
+   * Make adt-virt-null work properly (VirtSubProc runs `down' with
+     a single argument, so down must be sh -c and not []).
+   * In VirtSubProc close spurious copy of plumbing pipe, which prevents
+     certain hangs during error situations.
+   * Xen cleanup script runs dmsetup info / dmsetup remove several times
+     with some sleeps because xm destroy is not properly instantaneous.
+   * Fix handling of pre-built source trees.
+   * Fix cleanup handling not to delete tmpdir before resetting testbed's
+     apt.

    * Call dmsetup remove repeatedly instead of messing with udevsettle.
