| In dbt Cloud, there's a config which will now allow you to define the names of the columns that are created in the [snapshot table](/docs/build/snapshots#snapshot-meta-fields). Users can now set this config to use different names. |

i'm a little confused -- is this only for dbt cloud? i thought this was something avail to both cloud and core users since it relates to snapshots? maybe the diff is it's available to versionless users now and 1.9 users when 1.9 is launched?

small sugg that's not a blocker: maybe have the header outside the versionblock and tell users on 1.8 and lower that this feature is only avail in 1.9 and higher or versionless so they know?

I don't think this is the correct language.. something more like "customize the names of the dbt-generated meta fields in your snapshot tables"

Let's add an example?

| Note, if you rename snapshot columns without updating the existing table, it will cause an error. It's recommended to use this feature for new snapshots or update your existing tables before committing a column name change. | ||
| This feature will also be available in the upcoming 1.9 release. |
