Even though the final and official announcement will be made around Tuesday (Wednesday in Indonesian time), the source of Mozilla Firefox 6 is already being put on the FTP and the news has spread to many people, including Patrick himself, thus he builds the Firefox 6 for Slackware users and put them on -Current branch. It's not a common release by Pat to release a package before the main official announcement, but i think it's a worthed and safe upgrade for most users.
wget package is also being upgraded to the latest version. It's a new update after around two years without any update from the wget developers. The last release was made on September 22, 2009
