Bug#918890: [Python-modules-team] Bug#918890: pyyaml: New upstream release 4.1 (with incompatible load(), dump() behaviour)

[Scott Kitterman]

Upstream withdrew this release.  I'm in favor of switching to safe load by 
default, but I think we need to be careful about it.  I haven't checked the 
details on why 4.1 was withdrawn.  We may be better off cherry-picking the safe 
load changes.

Thanks for working on pyyaml.
