+### dbt list logging
+
+In [dbt version 1.5](/docs/dbt-versions/core-upgrade/upgrading-to-v1.5#behavior-changes), we updated the logging behavior of the [dbt list](/reference/commands/list) command to include `INFO` level logs by default.
+
+
+You can use either of these parameters to ensure clean output that's compatible with downstream processes, such as piping results to [`jq`](https://jqlang.github.io/jq/manual/), a file, or another process:
+
+- `dbt --log-level warn list` (recommended; equivalent to previous default)
+- `dbt --quiet list` (suppresses all logging less than ERROR level, except for "printed" messages and list output)
