+# 0.1.30 (October 6, 2022)
+
+This release of `tracing-core` adds a new `on_register_dispatch` method to the
+`Subscriber` trait to allow the `Subscriber` to perform initialization after
+being registered as a `Dispatch`, and a `WeakDispatch` type to allow a

+
+- `Subscriber::on_register_dispatch` method ([#2269])
+- `WeakDispatch` type and `Dispatch::downgrade()` function ([#2293])
+
+Thanks to @jswrenn for contributing to this release!
