 # Change Log
 
+## [0.13.1] 19 April 2023
+
+### Fixed
+- Improved performance of temporal merge node.
+  - The node doubles the array capacity if it's running out (instead of reallocating every iteration).
+
+### Changed
+- Point cloud formatting for `rgl_graph_write_pcd_file` is performed on the CPU now.
+  - We prefer to avoid transferring huge point cloud to GPU (risk of cuda out of memory error).
+
+### Known Issues
+- `rgl_graph_write_pcd_file` causes SEH exception on Windows when trying to save point cloud with ~375 000 000 or more points.
+  - The issue has been reported to PCL ([link](https://github.com/PointCloudLibrary/pcl/issues/5674)).
+
