Ussuri Series Release Notes


New Features

  • Support references in driver configuration values passed to cinderlib.Backend, such as target_ip_address='$my_ip'.

  • Improve list_supported_drivers method to facilitate usage by automation tools. Method now accepts output_version parameter with value 2 to get Python objects instead of having all values converted to strings.

Upgrade Notes

  • Python 2.7 support has been dropped. OpenStack Train ships the last release of cinderlib with py2.7 support (1.x). The minimum version of Python now supported by cinderlib is Python 3.6.
