Hello,
We are pleased to announce a new Flatcar Container Linux major release for the Alpha, Beta and Stable channel.
⚠️⚠️⚠️ End of support for CGroupsV1 in early 2025 ⚠️⚠️⚠️Stable 4081.2.0Flatcar will stop supporting the cgroups v1 backwards compatibility mode in Q1 2025. With our adoption of systemd-256, support for legacy CGroupsV1 will end in Alpha, Beta, and eventually Stable. Enabling legacy CGroupsV1 during deployment will not be supported anymore. Nodes that use CGroupsV1 legacy mode will fail to update. This ensures your workloads will not be disrupted. Enable CGroupsV2 on your legacy CGroupsV1 nodes in order to successfully update.
LTS-2024 will support CGroupsV1 until late 2025.
