Comment 4 for bug 19421

I've been wondering when updates for individual packages are offered,
how to find out about the changes, notably: are changes of category
security fix, bug fix, added features etc.

This is relevant if pending updates require large downloads,
and the user wants to reduce downloading to the most urgent updates.

Would this be a separate wish (as it is about much more fine-grained
changelogs than the original post)?
