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.

Many 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.
