Release Notes

The Elemental project stack is made of various components such as the Operator and UI for example.

Each of these components have an independent development lifecycle with its own versioning. Once a new version is ready, meaning it fully integrates with the others components of the Elemental project stack, a release is made.

Here's the different components, their latest version and a link to the respective release notes on GitHub:

NameVersionRelease Notes
Elemental Operatorv1.6.5Link
Elemental Toolkitv2.1.1Link
Elemental Linuxv2.1.3Link
Elemental UIv2.0.0Link
Information on docs versioning

The docs versioning is based on the Elemental Operator component as it's the user "entrypoint" to the Elemental project stack.

In order to install this release of the Elemental Operator check the project documentation.

For already existing deployments use the following Helm commands to upgrade:

# Install/upgrade the CRDS chart
helm upgrade \
    --install -n cattle-elemental-system --create-namespace elemental-operator-crds \
    oci://registry.suse.com/rancher/elemental-operator-crds-chart

# Install/upgrade the operator chart
helm upgrade \
    --install -n cattle-elemental-system --create-namespace elemental-operator \
    oci://registry.suse.com/rancher/elemental-operator-chart

To install or upgrade from the helm chart repository use:

helm repo add elemental-stable https://rancher.github.io/elemental-operator/stable/

and installed or upgraded with

# Install/upgrade the CRDS chart
helm upgrade --install -n cattle-elemental-system --create-namespace \
    elemental-operator-crds elemental-stable/elemental-operator-crds

# Install/upgrade the operator chart
helm upgrade --install -n cattle-elemental-system --create-namespace \

Known issues​

Predictable Network Interface Names​

The SLE Micro OS images with versions v2.1.1 and v2.1.2 (released in the default ManagedOSVersionChannel) adopt predictable network interface names by default.

This is a change from SLE Micro OS images previously released, so you should expect your Elemental hosts to switch the network interface names from the ethX template to the enpXsY one.

You can disable the predictable network interface names by passing the net.ifnames=0 argument to the kernel command line. To make it permanent:

grub2-editenv /oem/grubenv set extra_cmdline=net.ifnames=0
warning

The adoption of the predictable network interface names feature was not a planned one: it will be reverted in the next SLE Micro OS images starting from version v2.1.3. These OS images will include the net.ifnames=0 kernel command line argument by default.
The v2.1.3 OS images will be released via the default Elemental 1.6 channel.

SSH root access​

The SLE Micro OS images released in the current Elemental version (throught the default ManagedOSVersionChannel) do not allow ssh root access via password anymore. Easyest workaround is to either configure ssh root access via an ssh key or add a new user to the system.

Kernel Panic on hypervisors​

OS Images based on SL Micro 6.0 can fail to boot with a kernel panic on virtual machines using an unsupported CPU type.
The x86-64-v2 instruction set is required. For best compatibility CPU host passthrough is recommended.
