Thanks for the review and merge @casualjim!

[bvwells]

@casualjim do you know when you are planning to have the next patch release of this module?

[casualjim]

done

[bvwells]

Great! Many thanks @casualjim. I can roll this version out across other go-openapi modules if that is okay with you?

[casualjim]

That's fine although it's not strictly required

[bvwells]

The static analysers I am using analyse the go.sum file so even upgrading our code to the latest go-openapi/strfmt we still have go.sum entries for old versions of this module as the dependency of other go-openapi modules e.g. go-openapi/runtime.

I've noticed that there is a circular dependency between github.com/go-openapi/loads and github.com/go-openapi/analysis. Do you update this in any particular order?
