[#3867] Turn on partial parsing by default

CHANGELOG.md

@@ -8,6 +8,7 @@
 - Normalize global CLI arguments/flags ([#2990](https:/dbt-labs/dbt/issues/2990), [#3839](https:/dbt-labs/dbt/pull/3839))
 - Turns on the static parser by default and adds the flag `--no-static-parser` to disable it. ([#3377](https:/dbt-labs/dbt/issues/3377), [#3939](https:/dbt-labs/dbt/pull/3939))
 - Generic test FQNs have changed to include the relative path, resource, and column (if applicable) where they are defined. This makes it easier to configure them from the `tests` block in `dbt_project.yml` ([#3259](https:/dbt-labs/dbt/pull/3259), [#3880](https:/dbt-labs/dbt/pull/3880)
+- Turn on partial parsing by default ([#3867](https:/dbt-labs/dbt/issues/3867), [#3989](https:/dbt-labs/dbt/issues/3989))
 
 ### Fixes
 - Add generic tests defined on sources to the manifest once, not twice ([#3347](https:/dbt-labs/dbt/issues/3347), [#3880](https:/dbt-labs/dbt/pull/3880))
