+
+### Added
+
+- `testgroup.T.Run()` wraps `testing.T.Run()`, but passes your test a
+  `*testgroup.T` instead of a `*testing.T`. This makes it convenient to use
+  `testgroup.T`'s helpers when writing table-driven tests.
+
+### Changed
+
+- The test group will now fail if:
+
+  - the group object has no exported methods
+  - the group object is passed by value, and it has exported methods with a
+    pointer receiver
+
+  This should help catch mistakes when writing tests.
