More information about updates, please

[r12a]

It's great that we're getting regular updates– thank you for that! However, it is also a problem.

The number of changed files is very large, and i'd like to be able to decide whether or not i need to update the webfonts and images i created using (in my case, a wide range of) Noto fonts.

Is there a way we could add more information about what the changes were, or at least which issues the commit fixes? That would help users avoid unnecessary work but catch things that are substantive changes.
