This release contains: * primitives for #new and #@ * ExuperyMethodContext (allows full debugger support for compiled code) * interrupt checking (allows Alt-. and profiling to work inside compiled code)
Installation instructions are here: http://wiki.squeak.org/squeak/3945
The new primitive only works for pointer objects with less than 64 instance variables and are a fixed size (not Arrays). This covers most uses inside Smalltalk, and the new primitive can be easily generalised when there's a benchmark that requires it.

We delayed this release to fix a bug found by Andy Tween that seems to occur frequently on Windows but is cross platform. Thank's to Andy's help the bug is now fixed. And thanks for building the Windows VMs.
The next release will compile in the background.
