MessagePack for Ruby version 5

Today, I released the new version of MessagePack for Ruby!

Even faster
New API
API reference

Even faster

I rewrote all the code and achieved significant performance improvement, especially for serialization. I compared the new version to the old version (v4) using ruby-serializers benchmark, and the new version is faster for all data sets including Twitter, Image, Integers, Geo and 3D model.

CPU Price Performance: DigitalOcean vs Linode

On DigitalOcean, as you go up the plan, you get higher per-core price as well.
