If you're looking for the latest browser release, feed reader or video player check out Download.com. Run by the computing and technology supersite CNET, Download.com has release notes and reviews from CNET editors and users. You can also search the downloads by operating system or type of license (free, free-to-try, or pay.)
You can also find older versions of software downloads at OldVersion.com. There you'll find hundreds of versions of about 80 popular programs like iTunes, Yahoo! Messenger and Winamp. This site is particularly helpful if you're running an older operating system or working with an older computer that doesn't have a lot of memory resources.
