Breaking

Core and Supervised installation methods, and 32-bit systems

After a 6-month deprecation period, support for the Home Assistant Core and Home Assistant Supervised installation methods, as well as all 32-bit system architectures (i386, armhf, and armv7), has now been fully removed.

These installation methods and architectures will no longer receive updates, including security updates. If you are still using one of these installation methods or architectures, please migrate to a supported installation method and architecture as soon as possible to continue receiving updates and support.

For more information on this change, read the Deprecating Core and Supervised installation methods, and 32-bit systems blog post.

Breaking

Hive

Hive has removed support for their security products. We have removed the alarm control panel from the integration, as the Hive APIs no longer support these products.

Templates

The issues() templating method used to return all issues, including fixed issues. From now on, only active issues are returned.

Breaking

UniFi Protect

The legacy license plate event sensor has been removed from the UniFi Protect integration, as it no longer functions with Protect 6 and newer. The UniFi Protect integration has not been compatible with Protect versions older than 6 for quite some time.

This sensor has been replaced with a new Vehicle Detection Event entity that provides significantly more functionality, including license plate recognition, vehicle type detection, color detection, and confidence scores. The new event entity fires with a 3-second delay to ensure optimal thumbnail and LPR data quality.

For more information and automation examples, see the Vehicle Detection Event documentation.

Breaking

Xbox

  • The Xbox media browser has been completely overhauled to support multiple accounts and introduce a range of other improvements. As part of this update, the format of the media-source identifiers has been changed as well.
  • The following and followers sensors introduced in the last release previously included friends in their counts. After a recent API update, friends are no longer included.
