Second beta release since WWDC keynote
Apple is already reportedly supplying developers with a second preview version of Safari 6. The new code fixes a series of crashes caused by the old preview, which were related to entering two periods at the end of a string in the address bar, whether manually or through auto-completion. The second preview is following relatively quickly after the first, which debuted shortly after the WWDC 2012 keynote on Monday last week.
The preview software allows testing the new browser in OS X Lion. The finished version of the app will give the public access to features like iCloud Tabs, which syncs tab lists between Mac and iOS devices. It will also feature a new API for web audio, permitting effects in web apps like games. Expanded HTML5 support will permit things like web notifications and media synchronization.
