Apple has some teasers about Mac OS X 10.6: Snow Leopard and Snow Leopard Server
- Microsoft Exchange Support – Snow Leopard includes out-of-the-box support for Microsoft Exchange 2007 built into Mail, Address Book, and iCal. Mac OS X uses the Exchange Web Services protocol to provide access to Exchange Server 2007. Because Exchange is supported on your Mac and iPhone, you’ll be able to use them anywhere with full access to your email, contacts, and calendar.
- New Media Layer – Snow Leopard introduces QuickTime X, a streamlined, next-generation platform that advances modern media and Internet standards. QuickTime X features optimized support for modern codecs and more efficient media playback, making it ideal for any application that needs to play media content.
- OpenCL (Open Compute Library), makes it possible for developers to efficiently tap the vast gigaflops of computing power currently locked up in the graphics processing unit (GPU).
- iCal Server 2 – the next major release of iCal Server, which includes group and shared calendars, push notifications, the ability to send email invitations to non-iCal Server users, and a browser-based application that lets users access their calendars on the web when they’re away from their Mac.
- Address Book Server – Based on the emerging CardDAV specification, which uses WebDAV to exchange vCards, Address Book Server lets users share personal and group contacts across multiple computers and remotely access contact information without the schema limitations and security issues associated with LDAP.
- ZFS – Snow Leopard Server adds read and write support for the high-performance, 128-bit ZFS file system, which includes advanced features such as storage pooling, data redundancy, automatic error correction, dynamic volume expansion, and snapshots.
