The change made in 0.15.4 breaks httparty if frozen_string_literal is set to true

The change made in 2f80938 breaks our builds because of the use of gsub!

We use Ruby 2.3.3 with the # frozen_string_literal: true magic comment in preparation for immutable strings in Ruby 3.0

Can you give this branch a try to verify it fixes your use case? #540

Merged the PR. I'll wait up to a day to cut a new release to ensure that this fixes the problem.
