Following the release of Safari 5.1.3 earlier this week — which was bundled with the OS X Lion 10.7.3 update — Apple has seeded Safari 5.1.4 to registered developers. The release includes improvements to both JavaScript performance, and the way in which the browser handles PDF printing.
Apple is asking developers to test webpages that use JavaScript to identify compatibility issues, interaction with plug-ins and the appearance of plug-in content while zooming, and PDF printing from webpages:
Safari 5.1.4 Update for Mac and Windows
JavaScript Performance Enhancements
Safari 5.1.4 on Lion includes many fixes that enhance JavaScript performance. Please test webpages that use JavaScript and look for compatibility issues.
Plug-Ins & Zooming
Please test interaction with plug-ins and the appearance of plug-in content
while zooming. Please test zooming using gestures and keyboard shortcuts.
Printing PDFs
Please test printing PDFs loaded into Safari as well as PDFs displayed in iframes.
Using PDFs Printed from Webpages
Please test links in PDFs created from webpages using Safari 5.1.4.
The updates weigh in at 44MB for Lion users, 47MB for Snow Leopard users, and 109MB for Windows users. All of these downloads are available now from Apple’s Mac Dev Center, but you’ll need to be a registered developer to access them.
