== What was done engineering wise? ==
This past week we uploaded the 3.2.0-19.30, 3.2.0-19.31, and 3.2.0-20.32
kernels. This included a rebase to upstream stable v3.2.12, removal of
the non-smp PowerPC kernel flavor, updated SECCOMP patches, updated
AppArmor patches, and misc config changes and bug fixes. 3.2.0-20.32 is
the last kernel we intend to upload prior to Beta-2.
We have a few remaining Beta-2 work items. None are release critical.
We'll get them closed or postponed accordingly.
== What's about to land that might impact the other teams? ==
As noted, we've dropped the non-smp PowerPC kernel flavor . Should
any issues arise which would require us to reinstate the non-smp PowerPC
flavor, we will proceed with the proposal outlined on the mailing list:
