## v0.92

#### SQL

* Adjust null handling in the [`to_jsonb`](https://materialize.com/docs/sql/functions/#to_jsonb)
  function to match PostgreSQL's behavior. The functin now returns `NULL` when
  its input is `NULL`, rather than returning the JSON `null` value.

* Add `timeline_id` to the `mz_internal.mz_postgres_sources` system catalog
  table. This column registers the PostgreSQL [timeline ID](https://www.postgresql.org/docs/current/continuous-archiving.html#BACKUP-TIMELINES)
  determined on source creation.

#### Bug fixes and other improvements

* Fix a panic when calling the [`to_jsonb`](https://materialize.com/docs/sql/functions/#to_jsonb)
  on a list containing `NULL` array values.
