 ### Added
 
 ### Changed
+- Annotation: `Annotation.temporary_volume_layer_copy` now uses the NML-provided `scale`. [#644](https://github.com/scalableminds/webknossos-libs/pull/644)
 - Dataset: Moved the deprecation warning from `get_color_layers()` to the actually deprecated method `get_color_layer()`.
   [#635](https://github.com/scalableminds/webknossos-libs/pull/635)
 - Inconsistent writes to datasets properties (e.g., caused due to multiprocessing) are detected automatically. The warning can be escalated to an exception with `warnings.filterwarnings("error", module="webknossos", message=r"\[WARNING\]")`. [#633](https://github.com/scalableminds/webknossos-libs/pull/633)
