Right on the heels of yesterday’s release of Mac OS X Lion 10.7.3 that includes Safari 5.1.3, Apple seeded its developer community with Safari 5.1.4 for Mac and Windows. Apple advised developers to update their test machines to OS X 10.7.3, because it is a requirement for Safari 5.1.4 for Lion. Release notes and download links are available after the break.
