Safari 5.1.1 boosts JavaScript performance, fixes glitches

updated 05:05 pm EDT, Wed October 12, 2011

Simultaneous Mac, Windows updates

Included with OS X 10.7.2 and also available for Windows is Safari 5.1.1, an update of Apple's signature web browser. The release adds iCloud support and is said to increase JavaScript performance by as much as 13 percent over Safari 5.1. Much of the upgrade, though, is dedicated to patching up bugs, such as ones causing hangs, excessive memory use, instability and opening links in windows instead of tabs.

Efforts to smooth out the app have resulted in better handling of PDFs and printing, and more consistency when performing a pinch-to-zoom gesture. A Show Downloads option has been added to the View menu, and compatibility has been improved for embedded Flash video from sites like Vimeo. Similarly, East Asian characters should work more reliably in pages with Flash.

Fixed security holes include ones linked to Safari Extensions, file:// URLs, and Snow Leopard's treatment of SSL certificates. The bulk of the targeted vulnerabilities, however, were located in WebKit, the rendering engine underlying Safari and other web browsers like Google Chrome. In any case the fixes are directed at either both OS X and Windows, or OS X exclusively.

    Rubber band?

    Anyone know if this update allows you to disable the rubber band effect when scrolling with inertia?

    mp3 flash streaming

    This also fixes flash streaming of mp3 shoutcast and icecast stations broken since the first release of Lion.

    so far so good

    This update really increased safari's performance on my 10.6.8 iMac! It was getting out of hand: constant hang, reload, huge ram usage, etc.. this update seems to have fixed all that!
