Sorry, I forgot to push a version fix on the release branch -- done
now.  But note that there are some other issues with the release
branch at the moment.

As for `version->integer' it's working as it should -- returning #f on
an invalid version instead of throwing an error.  The problem is that
the previous version on the release branch was broken: it was
"5.2.900.0", and the version specs for X.Y.Z.W versions is W != 0.

Maybe `version->integer' should have thrown an error instead, but it
seems risky to change that behavior now.  On the other hand, it seems
reasonable to assume in code that (version->integer (version)) never
returns #f, since the currently running racket is assumed to be fine.
So I don't think that anything should be done (at least on the short

There is a safety check though in the build script that verifies that
the version is valid which should detect such problems early, but the
release branch build failed for a different reason, and failed earlier
than that check.  (Just in case, I verified now that it would have
killed the build with an error.)
