@jtcohen6 Would it be preferable to version block the Resource Details section to hide root_path for 1.4+ or simply add a note that it has been deprecated from 1.4+ beside the text?

FYI that https://schemas.getdbt.com/dbt/manifest/v8/index.html will be present as soon as we add it (dbt-labs/schemas.getdbt.com#16).

simply add a note that it has been deprecated from 1.4+ beside the text?

I'm happy with a deprecation note. Something like: "Note: Removed in dbt Core v1.4 / manifest v8, to reduce duplicative information across nodes."

Note: Once the v1.4 migration guide exists (#2646), we'll also want some notes under "What to know before upgrading," related to the metadata changes described in #2424.

good call, @jtcohen6 ! i agree that "Current" becomes misleading.

@matthewshaver : can you add this change to the v1.4 project page? i think it only mentions the task of removing versionblocks so it'll be good to capture this in our plans.
