   * pm-utils power.d updates now in Precise (thanks to pitti, slangasek)

=== Status: Precise Development Kernel  ===
  We rebased to v3.2.1 and uploaded linux-3.2.0-9.16 last friday.  I've
  also started prepping Precise LBM and plan to also open the Q git repo.
  Please keep in mind that Alpha 2 is nearing (Thurs Feb 2).  I plan on
  uploading our final Alpha2 kernel on either the Friday or Monday prior
  to the milestone.  For any patches needing to land in Alpha2, they need
  to be sent and applied before next Friday, Jan 27.

  In the last two weeks there have been 19 CVE added.  Many of these were
  older CVEs where fixes have already hit our trees so the fallout is
  somewhat mitigated.
