14 DAY TRIAL // In addition to all the preview releases for Mac and iOS reported yesterday, Apple rolled out an additional beta that didn’t get much attention in the press.
That beta is Safari 6.1 Seed 4, a pre-release version of Safari 6.1 for OS X Mountain Lion and Lion (available from the Mac Dev Center).
The seed includes the new Safari Sidebar, which makes it easy to access Bookmarks, Reading List, and Shared Links, as well as other features like Continuous Reading, easy Retweeting, a redesigned Top Sites view, third-party data blocking, iCloud Tabs auto-complete, built-in Yandex search, PDF sandboxing, and a truckload of WebKit enhancements and tweaks.
Other new features include support for high DPI with the image-set function, making it easier to specify when to use higher-resolution images for displays with high pixel density, HTTP strict transport security, and page visibility events.
