Thanks for the submission. This needs a CHANGELOG.md entry and then should be ready to go.

Dear @jertel

Thanks for accepting the change !

Do i have to decide a new release version and add the PR on the description om CHANGELOG.md ?

Best Regards, Edouard Fazenda.

You can add the changelog entry under the New Features section at the top of the file. It needs to follow the same format as the others. That's it.

@jertel

I think it would be best to fix the CHANGLOG, merge and incorporate it, and release the next version.
Good pull requests should be incorporated, and if there is no reply, shouldn't it be okay to just follow and incorporate them?

[nsano-rururu]

I think there may be reasons why they can't reply, such as being busy at work.

[nsano-rururu]

It should be incorporated since it was a pull request.

This is just my personal opinion.
