   Also @HaloKo4 -> those are not 'requirements' - those are 'constraint' files. This means that when you are installing airflow you can use those constraint files and they will "guarantee" that the installation will produce non-conflicting set of dependencies (as of 1.10.14 and 2.0.0). We have a process in place where during our CI builds we automatically upgrade to newer constraints where possible (and verify if airflow works and tests pass). Those constraints work in the 'worst' case when you install all "ci" extras "devel_ci" - which basically means "everything".
   
   You are still free to upgrade to newer version of any dependency for example if you only installed several extras and the constraints are only applied at airflow installation time.
