Slackware is either 32 or 64 bit (unless you're using multilib) and SlackPack provides some packages (e.g. Skype) only in 32 bit version, because the vendor does not provide 64 bit version. So I decided to split the 'Latest packages' list in two - for 32 and 64 bit packages as you're normally interested in either, but not both. The old feed is still available, but you could now update the URL and use either of the feeds for 32 or 64 bit packages.
In addition to this Advanced search was fixed (so "Latest only" option works again). And News calendar is now groupped by years. Also many of the links on the site (and in the news) were fixed or updated to avoid not found (i.e. 404) errors or redirects.
Update 2017-01-09: A small adition to Quick search Advanced search is the possibiltiy for exact match of the terms between double quotes (").
Happy New Year! Keep the faith!
