Apple has released Safari 5.0.1 for Mac OS X Leopard (10.5.x) and Snow Leopard (10.6.x), and Safari 4.1.1 for Mac OS X Tiger (10.4.x).
Safari 5.0.1 adds the ability to use extensions–features created by third-party developers. It also fixes a number of issues, including some we have noted with the 5.0 release. In particular, the update addresses an overaggressive prefetching mechanism that may cause problems with some routers and ISPs, resulting in browser slowness, inability to load pages, and problems with other devices connected to routers.
For a full list of enhancements, visit the Safari 5.0.1 download page.
Safari 4.1.1 offers similar fixes for Tiger users, but does not include the extensions functionality.
