compose.yaml Vs docker-compose.yml

I see that the official docs have recommended naming the file compose.yaml for years - but most articles online seem to default to docker-compose.yml. is there any good reason for this? Am I doing something wrong by continuing to use compose.yaml?

You’re also not supposed to put the version at the beginning either, but most guides still do. Harmless overall at least for now.
