I believe they're designed to be compatible both ways, I remember that
the 64-bit changes in particular were done in such a way that new tzdata
files work with older tzcode versions. I don't know if anyone else is
testing various combinations, though, so it probably would be good to
update tzcode anyway.

There was no changes outside tzcode files.
