Safari and WebKit Version Information
The Safari browser and WebKit-based applications communicate their version information to JavaScript code and web servers via the User Agent string. When Safari or its WebKit framework is modified, the build number for the portion that changed (Safari or WebKit) is updated. These updates to Safari and the WebKit frameworks are traditionally delivered via the built-in software update feature. Below are tables listing software updates for each relevant major release of Mac OS X and the resulting changes in the build information found in the User Agent string. This is a partial listing containing only the core updates generally considered important to web and WebKit developers. An XML rendition of the tables below is also available.
