+### DEP0112: dgram private APIs
+
+Type: Runtime
+
+The `dgram` module previously contained several APIs that were never meant to
+accessed outside of Node.js core: `Socket.prototype._handle`,
+`Socket.prototype._receiving`, `Socket.prototype._bindState`,
+`Socket.prototype._queue`, `Socket.prototype._reuseAddr`,
+`Socket.prototype._healthCheck()`, `Socket.prototype._stopReceiving()`, and
+`dgram._createSocketHandle()`.
