Hi @guerratron.
Your pull request has been detected as something other than a Library Manager submission.
A maintainer will need to review it before it can be merged.

If you intended to submit a library, please check the instructions and update your pull request if necessary:
https://github.com/arduino/library-registry/blob/main/README.md#instructions

@guerratron making pointless pull requests is NOT the appropriate way to update your library. You need to take the time to read the documentation:

https://github.com/arduino/library-registry/blob/main/FAQ.md#how-can-i-publish-a-new-release-once-my-library-is-in-the-list

It is true that we have a crude automated system for handling submissions, but it isn't some magical psychic robot that is able to infer your wishes from a pointless PR and grant them like a genie. So spamming this repository with pointless pull requests only wastes my time and your time. Please don't do that.
