Google drops OS X Leopard support for Chrome 22 dev release
 

Just as we catch wind that Apple's released the Gold Master version of Mountain Lion, the latest version of Chrome to hit the browser's developer channel -- that's version 22.0.1201.0, for the record -- isn't so supportive of OSX 10.5 and lower. Perhaps Leopard enthusiasts should take this as a friendly nudge toward to wild, snowy world of 10.6.
