AutoFill, subpixel rendering, extension compatibility and more being tested
On Wednesday, Apple released two betas for its Safari web browser, as well as a new beta for OS X Server. The Safari betas, 7.1 for Mavericks and 6.2 for Lion and later, add new features to WebKit, the rendering engine at the heart of the browser. In addition, Apple has asked testers to focus on general website compatibility in light of changes in some defaults, and tie-ins to forthcoming features in OS X and iOS. The new OS X Server beta requires the latest Mavericks (10.9.4).
This is the third such beta for Safari, with the referenced changes already present or expected to be present in Safari 8.0, which will appear with OS X 10.10 Yosemite when it is released in the fall. Testers are asked to focus on testing password and credit card AutoFill and extension compatibility. Subpixel rendering is now on by default for all web content, which may introduce some anomalies on certain websites or in-app web views "with extremely tight design constraints," according to the release notes.
In addition, CSS object model getters will return fractional double values based on the subpixel rendering and layout metrics, rather than the previous rounded integral values. Finally, testers are asked to examine searching from the Smart Search Field, particularly with different providers. No release notes for the OS X Server version 3.2 beta are yet available. All betas are available through Software Update for registered developers, or Apple's developer portal.
