Hi ,
I apologize for missing you in the credits for pull request. There was apparently a bit of a mixup when the ticket that your pull request was correcting was closed, and the ticket tracking the pull request itself was left open. I was not aware that the changes had already been implemented. I can try to make sure you are mentioned (belatedly) in the release notes for the next version of the Engine.
I did notice that you are already included in the Engine credits, and when I looked more closely I noticed that you were mentioned in the release notes for 4.9 for a different pull request, in case you wanted to use that one to show your contributions to your friends. Thank you again for your contributions to the Engine, and we look forward to seeing what you have to contribute in the future.
