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

 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.
