 ### Fixed
+- File names in LabelMe format export are no longer truncated ([#1259](https://github.com/opencv/cvat/issues/1259))
 - `occluded` and `z_order` annotation attributes are now correctly passed to Datumaro ([#1271](https://github.com/opencv/cvat/pull/1271))
 - Annotation-less tasks now can be exported as empty datasets in COCO ([#1277](https://github.com/opencv/cvat/issues/1277))
 - Frame name matching for video annotations import -
