Excellent :)
Where can I get a "bleeding edge" Squeak image?

To complete the instalation??  Can you remember why (the sender) it is
needing #mayor and #minor?
As far as I remember, it is only used by Fuel in FLBasicSerializationTest
>> expectedFailures
but that is not the installation, but running tests.

Thanks, I didn't know. Is there a way to run the tests in the test runner
so that it doesn't take into account such timeouts?
or can I change the global preference?  I ask so that to avoid changing
tests code (even if they would work for Pharo).

That's a good point. There must be something there for sure.

Thanks for the detailed answer. From what I can see, even if those tests
are wrong, "most cases" should work fine.
