+Overview of Changes in 4.13.0, 25-08-2023
+=========================================
+
+* GskPath, GskPathBuilder, GskPathMeasure:
+  Data types and APIs for path rendering. These APIs are still
+  considered experimental, and may change until 4.14. Please try
+  them out and give us feedback. Documentation can be found
+  here: https://docs.gtk.org/gsk4/paths.html
