Breaking Changes

• ContainerContainer image uses a new compression engine. Home Assistant container images are now compressed with zstd instead of gzip. Since containerd has supported zstd since 2021, this is not expected to break current installations. If you are running a very old container runtime, make sure it supports zstd before updating.
• LightsColour temperature in mireds has been removed. Use color_temp_kelvin instead.
• Template Fans
• TadoMobile device tracking has been removed from the Tado integration. Mobile devices and their associated device tracker entities are no longer available. This change resolves re-authentication issues and reduces unnecessary load on the Tado API.
• Z-wavePercentage speeds reported by Z-Wave fans have been corrected to align with other integrations.
