Congratulations to Projeto Fedora Brasil (Project Fedora Brazil) for releasing Fedora 7! Like Rodrigo de Oliveira already mentioned, the release notes are already available in Brazilian Portuguese. I can tell you it includes a lot of up-to-date software, including xorg-server 1.3 (which will be part of X.Org 7.3), GNOME 2.18, NetworkManager (which couldn’t be included in GNOME for now) and SCIM.

I met the project through Igor Soares, at the time of GNOME 2.18 translation. I wish you plenty of success!
