2. By Daniel Stone <email address hidden>

* Include patch from Ben Herrenschmidt to fix assertion of DDC GPIO lines
  after a DDC probe had finished, which would render Apple Studio Displays
  useless.
* Don't reset all templates when migrating from xserver-xfree86; this will
  render the template migration useless. Don't mess with $RECONFIGURE when
  migrating from xfree86. Set use_sync_ranges true when upgrading from
  xfree86 (closes: Ubuntu#8562, Ubuntu#8626).
* Use debug_echo liberally in xserver-xorg.postinst.in to tell us why we're
  writing out sync ranges.
