I have just uploaded 1.29.0 to unstable. It will need manual building with a non-buggy mips machine, to unblock us for Debian Testing. The previous build 1.29.0+dfsg1-1~exp1 failed due to hanging atomic tests:

https://buildd.debian.org/status/fetch.php?pkg=rustc&arch=mips64el&ver=1.29.0%2Bdfsg1-1%7Eexp1&stamp=1537686627&raw=0

I still think we should just RM rustc on mips64el.
