All xenial PPA Release files have now been re-signed with SHA-512 digests.

Depending on how recently they were changed, Release files for older Ubuntu series in PPAs may still be signed with SHA-1 digests, which may be noticeable for a small number of users who have pre-xenial PPAs enabled on xenial systems (myself included). We do plan to re-sign these as well; it involves some downtime for the PPA publication system, particularly for trusty, so we won't do it straight away, but it'll happen gradually over the coming weeks. I don't think there's further need to track it here, though.
