Apple has seeded a pre-release of Safari 5.2 to registered developers. Following the release of the OS X Mountain Lion developer preview this morning, a new beta of Safari has been made available with browser features from Apple’s upcoming desktop OS.
Namely, Safari 5.2 for OS X Lion introduces the unified, Google Chrome-like address/search bar. There are some other minor cosmetic changes that mirror the Safari version from the Mountain Lion developer preview.
