Released on September 1, 2022

New Features​

  • The Rook add-on can now be upgraded from version 1.0.x to 1.4.x or 1.5.x as part of the installation script for internet-connected installations only.

The upstream Rook project introduced a requirement for block storage in versions 1.3.x and later.
