List of dbt features not supported on dbt cloud

Hi
we are currently running dbt on Airflow (actually Astronomer managed airflow) but are performing a proof of concept (POC) study to determine if we can migrate to dbt cloud. I would like to know if there is a list of dbt features that are not currently supported on dbt cloud? For example it is only by reading a thread on this forum that I discovered that env_var is not supported on dbt cloud, which will entail quite a significant rework of our models.
Many thanks

As an aside I also think it would be great if there were a dbt cloud Category on this forum
