> Just look back at the Snow Leopard release of OS X. It was specifically marketed at having no new features and just being a fix and optimization release because Leopard was such a mess.

This is wrong. Leopard wasn’t “such a mess”. No one was saying Leopard was more buggy than Tiger.

Further Snow Leopard wasn’t a bug fixing release. It had a lot of new features. The difference is the features were not user facing but geared towards the underlying tech.

From Wikipedia:

> The goals of Snow Leopard were improved performance, greater efficiency and the reduction of its overall memory footprint, unlike previous versions of Mac OS X which focused more on new features.

> Much of the software in Mac OS X was extensively rewritten for this release in order to take full advantage of modern Macintosh hardware and software technologies (64-bit, Cocoa, etc.). New programming frameworks, such as OpenCL, were created, allowing software developers to use graphics cards in their applications.
