This public release has come after a developer release of the browser early last month.
Apple outlines the following changes in the update:
*Improve responsiveness when typing into the search field after changing network configurations, or with an intermittent network connection
*Address an issue that could cause webpages to flash white when switching between Safari windows
*Address issues that prevented printing U.S. Postal Service shipping labels and embedded PDFs
*Preserve links in PDFs saved from webpages
*Fix an issue that could make Flash content appear incomplete after using gesture zooming
*Fix an issue that could cause the screen to dim while watching HTML5 video
*Improve stability, compatibility, and startup time when using extensions
*Allow cookies set during regular browsing to be available after using Private Browsing
*Fix an issue that could cause some data to be left behind after pressing the “Remove All Website Data” button
This may sound strange as Safari 5.1.4 is available for Snow Leopard, Lion, and Windows but the above list of changes provided by Apple indicates that only Lion sees those benefits. Perhaps Apple has not yet updated a change list for Safari’s other platforms.
Safari 5.1.4 is available via Software Update or from Apple’s Safari webpage.
