    Hey PMURPH03!

    The change for the controlId will only impact Unity 2022.3 LTS, 2023.2 and 2023.3. (and all following versions)
    No other versions will be impacted.

    However I do not see a case were you would need to rely on that change, this should not break workflows or tools. If you want to discuss more about your topic, feel free to reach out to us through the Unity forums, and create a post over there and we will happily help you with your use case :D

    So the recommended workaround for this change is to use conditional compilation and just do UNITY_EDITOR_2022_3_14||...2022_3_15 || ...2022_3_16..... || 2022_3_XX || 2023_OR_NEWER ? As the OR_NEWER can't be used in this case.

    Will these changes be backported to older LTS versions of unity? Just so I can be prepared to work around the breaking change in other versions I need to support as well.
