As you know, Visual Studio 2008 and Team Foundation Server 2008 Service Pack 1 was released earlier this month. Most of SP1 was about bug fixes and performance, but it seems that the profiler team snuck in several new features as well:

• Adding support for instrumenting 64-bit managed C++ applications
• Improved instrumentation experience with pre-compiled web sites
• Shipping the 64-bit performance SDK (VSPerf.h, VSPerf.lib)
• Ability to load a previously saved filter on non-English VS installations

Here is a link to the VS2008SP1 readme and a page listing all of the SP1 downloads.
