Very true. I completely forgot about it because I don't use it.

But I have two comments.

1. Please don't use "-d", use "--devel-release" so that future
googlers don't think (as we've seen here in the past) that "-d" is
necessary for an upgrade to a non-development release.

2. If you're comfortable at the CLI, log out of GDM/KDM/... or boot
into single-user mode and use update-manager's CLI equivalent,
do-release-upgrade.
