Beat writers may find the Fedora 16 Technical Notes helpful:
http://jjmcd.fedorapeople.org/Download/F16_Technical_Notes/index.html
This document lists all new and changed packages between the Fedora 15
GA release and the current Alpha repository. Packages are listed by RPM
group, which might not always make sense to you, so be creative when
browsing RPM groups. If you are looking for a particular package, there
is a complete index by package name.
If a package is not listed in the document it means it has not changed,
at least as of this morning. Of course, this document will change as
Fedora 16 development continues, but the significant changes should
already be in the repo (and hence in the document).
