Warning: Upgrading CloudFormation templates that were applied from January 2025 or earlier will cause existing environments to no longer be accessible due to SSH port changes. Before upgrading, either stop and discard existing environments, or manually update the security group to allow access from 0.0.0.0/0 to port 22 (in addition to port 29222) after upgrading the stack.
