Apple released today Safari 4 beta, bringing their latest browser developments to the public including a revamped UI that happens to look a lot like Google's Chrome and an overhaul to its supported web standards. For an inadvertent release, Apple seems to feel pretty confident about their latest Safari 4 beta browser which is now touted as the default browser download from its official website for both Windows and OS X.


Similar to other tier 1 web browsers that are soon to get updated, namely the betas for Firefox 3.1 and Opera 10, the new Safari is boasting of a new JavaScript engine called Nitro that Apple claims performs up to 4.2 times faster than Safari 3. Support for the latest web standards also form part of this release which include implementations of HTML 5 and CSS 3.

If you've used Google's Chrome in the recent months, you will feel right at home with Safari considering they are both built around Apple’s own WebKit engine. In fact, Safari 4 replicates Chrome's bookmarks home screen with Top Sites which renders your most visited websites in real time. Other new and improved features include full history search, cover flow history browsing and full page zoom.
