 ALERT;CORE: Rules are now triggered by ItemStateUpdatedEvent instead of ItemStateEvent. If you use JSR223 scripting without helper libraries and expect a certain Java type, code changes might be needed.
 ALERT;CORE: The syntax for an item category/icon in a textual configuration file no longer accepts a value enclosed in quotes. So <temperature> is valid but not <"temperature">. Please update the definition of your items if necessary.
 ALERT;CORE: SCRIPT transformation has been removed and replaced with language-specific transformations: JS, RB, PY, DSL, GROOVY, etc. See https://www.openhab.org/docs/configuration/transformations.html#script-transformation

Furthermore, a bridge is now required and must be assigned to the `indego` thing. Configuration of username and password is no longer required/supported.
 ALERT;DanfossAirUnit Binding: The deprecated channel 'manual_fan_speed' has been removed. Please use channel 'manual_fan_step' introduced in 3.2.
 ALERT;Dark Sky Binding: Due to EOL of their API, this add-on has been removed.
 ALERT;Generac MobileLink Binding: Due to an API change, existing Generator Things will need to be deleted and added again. Additionally, existing Items will need to be adjusted to reflect the updated Generator Thing channels.
