Apple's web browser has joined its latest OS, and joins the dots on a raft of new features that we've been promised for a while. These include iCloud tabs and a new tab view -- both Mountain Lion only -- alongside a new smart search and unified search (with support for Chinese search giant Baidu) and address bar. If your older OS is missing out on those iCloud tabs, there's some other good news, Reading Lists will now work without being online -- which all sounds very in-flight friendly. There's also a Do Not Track option to cover your internet tracks, but for all the minute detail on some new developer additions, we'd advise hitting the source below.
Update 1: We're not spotting a Windows release yet -- and nor can we see whether it will work on Snow Leopard. Let us know in the comments if you manage to grab the latest iteration. For anyone on Lion, the update will be available from the Mac App Store.
Update 2: The latest version may not arrive on Windows -- with all references to the old version now gone from Apple's site. As 9to5Mac notes, nightly WebKit builds are still out there if you have a sudden pang for Safari. We've reached out to Apple to confirm.
