Exupery 0.10 is now released. There are prebuilt VM's available for
both Windows and Linux. This release now provides a measurable speed
improvement for the compilerBenchmark macro benchmark due to work on
dynamic primitive inlining.
Instructions for installation and a link to a pre-built image is
here:

It's interesting that on Andy's machine Exupery is providing a nice
performance improvement for largeExplorers while on my machine there
is a 7% performance loss. The loss is due to the interpreter inlining
Point>>@ into the main interpreter loop while Exupery executes it as
a normal primitive. Andy's benchmarks are promising enough for a 1.0,
pity relative performance isn't so high on the other two machines.
There is a mailing list for those interested in the project here:
http://lists.squeakfoundation.org/cgi-bin/mailman/listinfo/exuperyMany thanks to Andy Tween for doing the Windows port and building
the official Windows VM. Thanks also to Patrick Mauritz for doing
a Solaris x86 port which was the first OS port.
