1.0 - 2.0 is equivalent to >=1.0.0 <2.1

~1.2 is equivalent to >=1.2 <2.0.0, while ~1.2.3 is equivalent to >=1.2.3 <1.3.0

^1.2.3 is equivalent to >=1.2.3 <2.0.0 as none of the releases until 2.0 should break backwards compatibility. 
pre-1.0 versions it also acts with safety in mind and treats ^0.3 as >=0.3.0 <0.4.0

1.2.3	=1.2.3.0-stable
>1.2	>1.2.0.0-stable
