This is a pre-announcement so that people who are thinking of attending LinuxCon and/or Plumbers Conference can take advantage of the first level of early registration for LinuxCon, which ends June 1st (this Monday).
A full announcement for the SELinux developer summit with a CfP will follow shortly.
