+## New board support: Hardkernel ODROID-M1
+
+Home Assistant OS 10 supports the Hardkernel ODROID-M1 single board computer!
+Most notably, the ODROID-M1 supports NVMe SSD storage natively, which makes it
+another great choice to run Home Assistant on. With its quad-core CPU with up
+to 2&nbsp;GHz and up to 8&nbsp;GB of memory it is suitable even for demanding Home
+Assistant installations.
+
+Currently, Home Assistant can be booted off an SD-card or an eMMC. Note however
+that a new boot firmware (Petitboot) is required to boot from eMMC (see
+the board-specific documentation). NVMe SSD boot is currently not supported
+by the boot firmware. However, an NVMe SSD can be used through the data disk
+feature.

+
+## Improved data disk feature
+
+The data disk feature allows extending storage by adding an external disk.
+When using the data disk feature, all commonly read and written data is moved
+to that storage, just Home Assistant OS itself remains on the existing storage
+(for example, SD-card or eMMC). Home Assistant OS is a read-only operating system &mdash; the
+OS partitions are only written to when updating the operating system. This makes
+sure that there is minimal wear on the existing storage.
+
+In this OS release, together with the latest version of the Supervisor, the
+data disk feature got more user-friendly: The data disk choice lists the actual
+model of available data disks. In situations where previously an attached disk
+would not show up, the disk will now be reliably detected and available as the
+new data disk. Now it is also possible to move from one data disk to another:
+Simply connect another disk, and go to the **Move data disk** dialog again. On
+reboot, the data will be moved and the old data disk can be detached.
+
+You can find the move data disk feature under **Settings** > **System** > **Storage** in
+the top right overflow menu.

+
+## Advanced memory management
+
+With Home Assistant OS 10 low memory, devices will generally perform better.
+Firstly, we moved from zram to zswap, which allows us to use the storage as an
+actual swap space. We’ve tuned the memory management to minimize the number of
+writes to storage (to prevent unnecessary wear on SD-cards and other flash
+memory-based storage).
+
+We’ve also improved reliability and responsiveness in low-memory situations:
+Home Assistant OS uses a new memory management mechanism named Multi-Gen LRU
+along with thrashing prevention. This makes Home Assistant OS recover quickly
+from a low-memory situation and remain responsive.
+
+In general, we recommend using a board with at least 1&nbsp;GB of memory and make
+sure to stay well below 80% memory utilization. You can monitor the overall
+memory utilization under **Settings** > **System** > **Hardware**.
+
+## Updated software packages
+
+Home Assistant OS is built using the latest release of Buildroot 2023.02. It
+comes with the latest Linux kernel with long-term support (6.1). This means
+updated drivers and better device support. It uses the latest version of
+Docker 23.0.3, our container engine powering the Supervisor and our add-ons.
+The latest version of the Bluetooth package BlueZ 5.66 comes with various bug
+fixes for improved communication with Bluetooth devices. Network Manager
+1.40.16 has proven to work more reliably with third party Thread border routers,
+specifically with Apple border routers. We also improved the IPv6 Neighbor
+Discovery support on Home Assistant OS specifically for Thread: Home Assistant
+OS will now quickly discover when border routers disappear from the network and
+use alternative border routers, if available.
+
+We hope you enjoy Home Assistant OS 10.0! If you have any questions or feedback,
+please let us know.
