major_changes:
- >-
  ``ansible-galaxy install`` and ``ansible-galaxy collection install|download`` -
  collections that declare a ``requires_ansible`` version that is not compatible with the running ansible-core version are now excluded from installation and download by default. In previous versions, ansible-galaxy would install such collections even if doing so resulted in an error at load time. To restore the previous behavior, set ``COLLECTIONS_ON_ANSIBLE_VERSION_MISMATCH`` to ``ignore`` in your configuration.
