+Remove Python 3.7 support in new releases.
+Under Python 3.7 `pip` will keep resolving the latest version of the package that supports active interpreter.
+This change comes at benefit of using newer versions of B2 CLI dependencies in `b2` standalone binary as well as in the official docker image.
+Python 3.8 is now the minimum supported version, [until it reaches EOL in October 2024](https://devguide.python.org/versions/).
+We encourage use of latest stable Python release.
+If Python interpreter upgrade from 3.7 is not an option, please use provided standalone binaries or official docker image.
