The choices are these

• Use ''.dup or String.new('') or +''.
• Magic comment frozen_string_literal: false like Shopify/httpclient.
• Ignore warnings until Ruby v3.4 policy is finalized.
• and other...

Hi @tmimura39 I made a PR that hopefully should resolve the issue

[tmimura39]

Thanks. Yes, I agree. I think that will resolve this issue 😄

Any update on that? Ruby 3.4 is publicly available now.

[chaadow]

please could you look at my PR @pmcanseco thanks

Is there any progress on this issue? We updated to Ruby 3.4 and we're seeing these warnings as well. The next version of Ruby isn't far off, and while it doesn't seem like the change to frozen strings will happen this year, it's still better to get ahead of the change.
