Pessimistic operator doesn't handle beta versions properly

[hwo411]

[10] pry(main)> v = Semantic::Version.new('2.0.0-beta')
=> #<Semantic::Version:0x000055d8286340b0 @build=nil, @major=2, @minor=0, @patch=0, @pre="beta", @Version="2.0.0-beta">
[11] pry(main)> v.satisfies?('~> 1.0')
=> true

It should return false for it, since it's no longer version 1

Also the same happens with
[29] pry(main)> v.satisfies?('<2')
=> true

I think <2 should behave as MAJOR < 2, not version < 2.0.0

So I ran into the same issue and did some digging. The responsible code is here: version.rb#L35.

After reading through the Semantic Versioning Spec it actually specifies this behavior in point #9, so the library is working as intended.

As to dealing with this behavior, I use the earliest possible pre-release version as my comparisons instead. For example, first the old comparison, then then the way I propose:

irb(main):021:0> Semantic::Version.new("9.2.0-b22") >= Semantic::Version.new("9.2.0")
=> false
irb(main):022:0> Semantic::Version.new("9.2.0-b22") >= Semantic::Version.new("9.2.0-b1")
=> true

@jlindsey Looks like this can be closed. Might be worth adding a line or two to the README
