Home Assistant OS (HAOS) 18.0

Home Assistant OS 18.0 is a major release bringing significant updates to all platforms. The Linux kernel has been updated from 6.12 to 6.18 across all targets, Docker has been upgraded to v29.5.3 with containerd v2.2.4, and the underlying Buildroot has been updated to 2025.02.14. Disk images are now significantly faster to flash, the default swap size is now bounded to avoid problems on systems with very low or very high amounts of RAM, and the Raspberry Pi bootloader firmware can now be updated directly from Home Assistant. All users are recommended to update. The Raspberry Pi bootloader (EEPROM) firmware can now be checked and updated directly from Home Assistant OS. Home Assistant Core 2026.7.0 will also expose the firmware as an update entity. Note that updating the firmware is only possible when the system is booted from an SD card, or in general on Raspberry Pi 5 and on Home Assistant Yellow with a CM5.
