Apple has released the the fifth Safari 10 beta for the OS X 10.11.6 and OS X 10.10.5 for developers who want to further test out the upcoming Safari 10 version without the need of updating their Mac devices to the macOS Sierra from either OS X Yosemite or OS X El Capitan.

Available to download over-the-air and via the Apple Developer Center website for registered Apple developers, the new Safari 10 beta comes with some of the new features and functions of the official Safari 10 version that is slated for a fall release alongside the macOS Sierra, according to MacRumors.

The fifth developer Safari 10 beta has a new Bookmarks sidebar that lets users focus in on a specific folder with a double-click. In addition, the Bookmarks display has been redesigned along with the History list.

Developers who will be getting the Safari 10 beta 5 can also check out the improved ranking system of frequently visited websites, the site-specific zooming feature, the Web Inspector Timelines tab, the enhanced Autofill command that automatically fills out tabs with data from Contacts, HTML5 support and legacy Plug-ins and the new Spotlight feature that includes suggestions for Top Hits.

Just like the previous betas, this new one also comes with Safari Extensions, which means developers can use the preview in making extensions for the Safari 10 app and make them available later on the Mac App Store.

Though the Safari 10 beta 5 is pretty packed with many new features and improved implementations, there are still features not included in this one, such as the Apple Pay on the Web and Picture in Picture. Both features are only available on the macOS Sierra developer beta, as per 9To5Mac.

Meanwhile, the official Safari 10 version that will arrive with the macOS Sierra is said to disable Adobe Flash by default and only allows users to view flash content on a case-by-case basis. This functionality is being implemented to ensure that the Web browser would function more efficiently and securely.
