# 2.2.x Stable Releases
See https://www.pantsbuild.org/v2.2/docs/release-notes-2-2 for an overview of the changes in this release series.
This is the first release to require having a Python 3.7 or 3.8 interpreter to run Pants. Run curl -L -o ./pants https://raw.githubusercontent.com/pantsbuild/setup/2f079cbe4fc6a1d9d87decba51f19d7689aee69e/pants to update your ./pants script to choose the correct interpreter.
This release also removes the ability to use %(pants_bootstrapdir)s and %(pants_configdir)s in interpolations in your config file.
