Windows/Mac: Safari 5.0.1 is out and it's much more than just a bug fix. Installing the update activates Safari's new extensions platform, which has roughly 100 extensions available through the Safari Extensions Gallery.
From an early look around, the majority of Safari's extensions are more akin to GreaseMonkey-style scripts than full-on Firefox extensions. Most appear to be related to the functionality of a single site or making certain web apps easier to access — not that there's anything wrong with that. Tools and offerings for Gmail, Instapaper, eBay and other popular services abound.
