fixes #67
need it to resolve dependencies

Wouldn't be >= 0.6.1 the better solution here?

[romand]

why? it would allow 2.0.0, which may bring breaking changes (:

[tillsc]

>= 0.6.1, < 2.0.0 then. If dm-types works with 0.6.1 why forcing someone to update?

[romand]

yep, I agree its better

@romand @tillsc If this is still valid (versions of safe_yaml, that is) I can merge it and try to get it in 1.3.0.
