Apple has issued a new version of its Safari browser for Mac and Windows users, pushing version 5.1 and 5.0.6. The update includes fixes for Java, Webkit and a flaw in the browser s CFNetwork API that could enable cross-site scripting (XSS) attacks. Safari has enabled private autofill, allowing users to select how much of their contact information is saved, along with revamped cookie settings and sandboxing. Apple has added some Lion-specific features to Safari including an Instapaper-like Reading List and full-screen browsing.
