The release candidate 1 of the free edition of Ruby In Steel has now
expired (this took us by surprise as much as anyone - we had thought the
expiry code had been removed!) - anyway, apologies to anyone who was
unable to work with it today. We’ve issued a new version, RC2, available
for immediate download. This should never expire and, in any case, we
will be launching the full version 1.0 in a few days.
