Release 0.6.0 not fully working with newest Consul version

Hi,

I recently use consulate to register / deregister services. 

In 0.6.0, deregister method use GET method. Consul doesn't use anymore GET for deregistering service. In master branch, it's PUT method and working well. 

It's possible to release a new version with this fix (and i think, many other) ?

Thanks
