 .
   [ Martin Pitt ]
   * debian/control: Add X-Vcs-Bzr.
   * autostart/restricted-manager.desktop.in: Fix capitalization. (LP: #103248)
   * RestrictedManager/core.py: Keep track of whether a module's enable status
     has changed throughout program runtime, add method is_changed().
   * restricted-manager: Only set status 'needs computer restart' if the module
     actually has been enabled/disabled. This avoids marking modules as 'needs
     computer restart' which haven't been touched, but were not loaded due to
     missing hardware (such as the commercial OSS drivers). (LP: #102468)
   * restricted-manager: Disable tree view while enabling/disabling a driver
     (which takes a long time for X.org drivers). (LP: #103129)
   * RestrictedManager/xorg_driver.py: Move DefaultHandler enable/disable calls
     after package installation and check, so that aborted package operations
     do not cause the module to get (un)blacklisted and the UI to become
     inconsistent. (LP: #104111)
   * RestrictedManager/nvidia.py: Add class NewNvidiaDriver for the new
     nvidia-glx-new driver package.
 .
   [ Johan Kiviniemi ]
   * debian/apport_hook.py, debian/rules: Add an apport hook that attaches
     /etc/X11/xorg.conf and a list of connected devices to the bug report.
   * RestrictedManager/core.py: Also read the modalias overrides now provided
     by linux-restricted-modules.
   * modalias_override/{ath_hal,fglrx,nvidia}: Remove, since l-r-m provides
     them now.
