It is the final version. You "lucked in" - you caught the files in a
window of time whilst we were waiting for them to propagate to the
mirrors. Now they are officially hidden until the release time.
Release time is...well...study what is happening in the Firebird
community over the next few days and you should be able to work out
when the release is planned to appear. :-)
