 ## In progress: 0.142.0
 
+- Support non-standard `audience` query parameter on `GET /jobs/{job_id}/logs` (e.g. `all` to include developer-only logs), passed to `BatchJobs.get_log_entries` ([openeo-geotrellis-extensions#872](https://github.com/Open-EO/openeo-geotrellis-extensions/issues/872))
 - Add `resample_cube_temporal` process (`DriverDataCube.resample_cube_temporal`, dry-run support, validation of `dimension`/`valid_within`)
 - Require at least Python 3.11 (drop support for Python 3.8, 3.9 and 3.10 [#370](https://github.com/Open-EO/openeo-python-driver/issues/370))
 - Require at least PySTAC 1.10 ([#396](https://github.com/Open-EO/openeo-python-driver/issues/396))
