It's published here:
http://hg.python.org/releasing/3.4/
There's also a tarball at the old web site:
http://midwinter.com/~larry/3.4.status/
However, the "merge.status.html" page is broken. I'm not going to
bother to fix it, instead please just look at the hg repo above. I
think part of the problem is that some revisions I had to manually
patch in (instead of grafting) wound up with my name instead of the
original core dev's name, so the translation between the 3.4 and
default branches got broken.
Anyway, it locally builds and runs tests without errors.
