+## What's new?
+
+Stable 3975.2.0 introduces a wide range of features, packages updates, and security fixes. The major release focusses on introducing support for new vendors, new officially maintained sysexts.
+
+### New vendors
+
+Over the past few months, the team has continued to invest in Flatcar support on cloud providers, enhancing existing support with better documentation and an improved user experience. Flatcar Stable now supports Hetzner and Scaleway, as well as KubeVirt images.
+
+### Sysext
+
+Docker and Containerd have been available on Flatcar as sysext images for a while now. The Flatcar team now provides official sysext images that can be enabled at boot on Flatcar. These images are built in Flatcar CI and are officially maintained. Starting from this Stable release, you will be able to run ZFS or Podman systemd sysext extensions, with more sysext extensions to follow (e.g., Python). Flatcar sysext images are now split into two categories:
+
+- Official:
+  - enabled by default: Docker, Containerd, OEM
+  - disabled: Podman, ZFS
+- Community supported: from the Flatcar sysext-bakery: https://github.com/flatcar/sysext-bakery
+
+Browse the documentation for more information: https://www.flatcar.org/docs/latest/provisioning/sysext/#types-of-systemd-sysext-images
+
+### Kernel & TPM
+
+With the Stable release, we bump the Linux kernel version from 6.1 stream to 6.6. The release also introduces a long-awaited feature of disk-encyption 🔒. With this release, you can perform for TPM-backed disk encryption with systemd-cryptenroll and Clevis, and with a network-backed disk secret store with Tang.
+
