"Apple on Thursday seeded to developers new builds of Safari for OS X 10.9 Mavericks and OS X 10.8 Mountain Lion featuring new WebKit modifications including WebGL tweaks, which should see wider adoption in OS X 10.10 Yosemite and iOS 8.\r\n\r\n&amp;lt;div align=\"center\"&amp;gt;&amp;lt;img src=http://photos.appleinsider.com/gallery/9850-1795-140711-Safari-l.png alt=\"\" /&amp;gt;\r\n&amp;lt;span class=\"minor2 small gray\"&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;/div&amp;gt;\r\n\r\nSafari 7.1 for Mavericks and Safari 6.2 for Mountain Lion brings WebGL-powered 3D rendering to Apple's browser, as well as other WebKit engine features like IndexedDB, JavaScript Promises and CSS Shapes and Compositing.\r\n\r\nApple is asking developers testing the latest seeds to concentrate on subpixel rendering, which is now on by default for all Web content. According to the release notes, websites with in-app Web views may render differently depending on design constraints. \r\n\r\nAdditionally, the company requests focus on extension compatibility. \r\n\r\nAs for the new WebKit features, Apple notes the following:\r\n\r\n&amp;lt;ul&amp;gt;&amp;lt;li&amp;gt;WebGL. Safari support for WebGL allows developers to create 3D experiences \r\nthat work natively without plug-ins.\r\n&amp;lt;li&amp;gt;IndexedDB. The IndexedDB API allows web developers to store structured \r\ndata for web applications that work online or require large amounts of data to \r\nbe cached client side.\r\n&amp;lt;li&amp;gt;JavaScript Promises. Safari enables JavaScript authors to more naturally \r\nwork with asynchronous programming patterns.\r\n&amp;lt;li&amp;gt;CSS Shapes and Compositing. Using CSS, websites can now easily \uFFFD\uFFFD'ow text \r\naround images and geometry shapes, and perform image compositing \r\noperations on DOM elements.&amp;lt;/ul&amp;gt;\r\n\r\nDevelopers can download Safari 7.1 for Mavericks and version 6.2 for Mountain Lion via Apple's &amp;lt;a href=\"https://developer.apple.com\"&amp;gt;Developer Portal&amp;lt;/a&amp;gt;."^^<http://www.w3.org/2001/XMLSchema#string>
