Exupery

• SqueakL + MIT - Dual licensed under both SqueakL and MIT. This enables both base Squeak inclusion and 100% reuse. Recommended prior to 4.0.
• MIT - The MIT license is like BSD without the advertising clause. As free as it gets, suitable for cross Smalltalk 100% reuse. The recommended license for Squeak since the 4.0 release.
• Squeak3.9 - Released 8 Dec 2006.
• Squeak3.8 - Released 25 May 2005.
• Alpha - Useable by daredevils. Probably still full of bugs.
• Code changes, may break compatibility - Code has changed and may break clients, but not necessarily.

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:

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.
