Safari 9.1

Apple has released Safari 9.1 for OS X 10.9.5 Mavericks, 10.10.5 Yosemite, and 10.11 to 10.11.3 El Capitan — it’s bundled into 10.11.4 El Capitan (see “OS X 10.11.4 Improves Notes, iBooks, and Live Photo Support,” 21 March 2016). The update brings an updated version of WebKit with enhanced support for images, CSS, and Web formats, plus it improves Web Inspector performance and prevents JavaScript dialogs from blocking access to other Web pages. It also receives several security patches, including fixes for a cookie storage issue that existed in the Top Sites page, memory corruption issues that could lead to arbitrary code execution when
processing maliciously crafted Web content, and a caching issue with WebKit character encoding (see this security content article at Apple’s Support Web site). Safari 9.1 is available only via Software Update. (Free, 10.9+)
