Checklist
[X] If you are requesting a merge into master, confirm this code is production-ready and can be included in future releases as soon as it gets merged
[X] Make sure either the unit tests and/or the QA tests are capable of testing the new features
[X] Make sure you do not include new dependencies in the project unless strictly necessary and do not include dev-dependencies as production ones. More dependencies increase the possibility of one of them being hijacked and affecting us.
