Lion DP3 reveals Reading List in Safari, more

Apple has given its developers new tools today, ahead of June's Worldwide Developer's Conference (WWDC) meeting in San Francisco. Available only via Software Update, authorized users of the developer preview of Lion (version 2.2) can now download Lion DP3, which brings with it a number of new features and tweaks. The company also unveiled Xcode 4.1 DP5, the fifth beta of the updated tool expected to be finalized before the WWDC starts. Xcode 4.1 DP5 is available from the Mac Dev Center, and requires the Lion DP3 release to be installed first.

The main new feature in Xcode DP5 is the inclusion of a new version of the iOS software development kit, labelled version 4.3. Any specific changes to Xcode and the iOS SDK in DP5 have not been detailed, but Apple cautions developers to use it for testing only, relying instead on Xcode v3.2.5 or v4 for any development that is intended for the Mac or iOS app stores. Xcode 4.1 has been in "developer preview" mode since February.

Lion DP3 follows on the heels of two unusual updates to the previous preview. Like the previous releases, Lion DP3 requires a 64-bit Intel-based Mac running either OS X 10.6.7 or Lion DP2 with both updates to DP2 installed. The update is a large 10.7GB in size, and contains an assortment of minor new features and improvements.

Chief among the changes is the addition of the Reading List to Safari, enabling users to save web pages for later reading, first discovered as a hidden feature in DP2. At present, the feature does not sync to any cloud service, remaining locally-stored (which is likely to change in the final release).

The latest preview also contains a new Reminders menu in iCal, some changes to Spaces management, an actual Mission Control app with new features, new wallpapers and the ability of scrollbars to change shade based on the page they are attached to (white background would darken the scrollbars; dark pages would lighten them).
