Hello all, Does anyone starting from which release the DLT table would have these three expectations column? DROP_EXPECTATIONS_COL, MEETS_DROP_EXPECTATIONS, ALLOW_EXPECTATIONS_COL?

This channel is for Delta Lake, the open-source Lakehouse storage format. Delta Live Tables is a feature in Databricks, which builds on top of Delta Lake, but is not part of this project. For info regarding Databricks (that is not directly related to Databricks), you'll have to reach out to a Databricks community (e.g. the Databricks subreddit). I believe you can find the information that you are looking for here: https://docs.databricks.com/en/release-notes/delta-live-tables/index.html
