Apple today released Safari 8.0.6 which is recommended for all OS X Yosemite users.
Safari 8.0.6 contains improvements to security.
Apple today also released Safari 7.1.6 and Safari 6.2.6 for users of earlier OS X versions.

I note two whopping security holes that could PWN a Mac if exploited. This is, therefore, a critical update.
Also, I would never use Safari 5 at this point in time due to the above noted whopping security holes and others. Use something still being updated that is backwards compatible with older versions of OS X, such as Leopard Webkit or Firefox, which still runs on OS X 10.6.
This has not shown up in my Updates in App Store. Weird! I’m currently on Safari 8.0.5, I just checked.
Just showed for me at 9:25 EST
Got it last night. Less zip today though.
Not available for 10.10.4 beta testers yet (officially)
that’s why.
