Ubuntu Software Updater provides no grub info and broken link too

[LukeKendall]

I noted that for some reason, there is no information about changes provided for this critical piece of software (grub2), and worse than that, the link provided in the Software Updater leads you to a page that does not exist. E.g. it reports:

Installed version: 1.66.6+2.02~beta2-36ubuntu3.6
Available version: 1.66.7+2.02~beta2-36ubuntu3.7

The list of changes is not yet available.

Please use http://launchpad.net/ubuntu/+source/grub2-signed/1.66.7+2.02~beta2-36ubuntu3.7/+changelog
until the changes become available or try again later.

I find it reprehensible that the changelog is not provided for such a critical piece of system software.
