+# 2027.0.10
+
+## Bug fixes
+
+- Fixed a polymorphic record serializing as an empty JSON object in a `RevitApiUiTest` on Revit 2025 https://github.com/Nice3point/RevitUnit/issues/139.
+ A test project that ships a later package of a runtime assembly, such as `System.Text.Json` 10.0 on Revit 2025, loads one copy of that assembly for every reference.
+
# 2027.0.9
