@BnitoBzh thank you for doing this! It's been on my todo list for quite some time but I've had an extremely busy 6 months or so. These changes all look great, we just need to get the tests passing in CI. The failures appear to be due to it using Node 12 (at least one of the packages you bumped requires Node 14), however I think it's fair to drop Node 12 support at this point. This will be a breaking release anyway, so can you try updating this package to drop Node 12?

My recommendation would be that we set the package.json to allow Node 14 and Node 16+, and then use Node 16 in CI if we can: https://github.com/elwayman02/ember-resize-modifier/blob/master/.github/workflows/ci.yml

Thanks again! I'll try to get this released by next week at the latest.
