+The `url.parse()` function is now deprecated and has been replaced by `new URL()` (see [8af7019](https://github.com/socketio/socket.io/commit/8af70195bb8c5bc3efe9685997ab6373fb8b1ca9)).
+
+### Bug Fixes
+
+* call adapter.init() when creating each namespace ([f3e1f5e](https://github.com/socketio/socket.io/commit/f3e1f5ebdf59158d0c8d1e20f8230275617fb355))
+* improve `io.close()` function ([#5344](https://github.com/socketio/socket.io/issues/5344)) ([bb0b480](https://github.com/socketio/socket.io/commit/bb0b480d2ab3108a8ae255b539015da451fdb249))
