 - Changes unit tests using `assertRaisesRegexp` to `assertRaisesRegex` ([#4136](https://github.com/dbt-labs/dbt-core/issues/4132), [#4136](https://github.com/dbt-labs/dbt-core/pull/4136))
 - Allow retries when the answer from a `dbt deps` is `None` ([#4178](https://github.com/dbt-labs/dbt-core/issues/4178))
 
+### Docs

+- Fix non-alphabetical sort of Source Tables in source overview page ([docs#81](https://github.com/dbt-labs/dbt-docs/issues/81), [docs#218](https://github.com/dbt-labs/dbt-docs/pull/218))
+- Add title tag to node elements in tree ([docs#202](https://github.com/dbt-labs/dbt-docs/issues/202), [docs#203](https://github.com/dbt-labs/dbt-docs/pull/203))
+- Account for test rename: `schema` → `generic`, `data` →` singular`. Use `test_metadata` instead of `schema`/`data` tags to differentiate ([docs#216](https://github.com/dbt-labs/dbt-docs/issues/216), [docs#222](https://github.com/dbt-labs/dbt-docs/pull/222))
+- Add metrics ([core#216](https://github.com/dbt-labs/dbt-core/issues/4235), [docs#223](https://github.com/dbt-labs/dbt-docs/pull/223))

 ### Under the hood
 - Bump artifact schema versions for 1.0.0: manifest v4, run results v4, sources v3. Notable changes: schema test + data test nodes are renamed to generic test + singular test nodes; freshness threshold default values ([#4191](https://github.com/dbt-labs/dbt-core/pull/4191))
 - Speed up node selection by skipping `incorporate_indirect_nodes` if not needed ([#4213](https://github.com/dbt-labs/dbt-core/issues/4213), [#4214](https://github.com/dbt-labs/dbt-core/issues/4214))
