+### Node.js Bridge
+
+Q 1 supported a wide variety of `n*` methods for bridging to Node.js. In
+practice, few of these were used. This release scales back support for the
+Node.js bridge to the essential `promise.nodeify`, `Q.denodeify`, and
+`Q.ninvoke`.
+
+The beahvior of `denodeify` has been altered to match the behavior of
+[RSVP.js][]’s `denodeify`. The version of this method in Q v1 would infer that
+the method provided a variable number of arguments (variadic arguments) if the
+nodeback was called with more than one non-error argument. This leaves a glaring
+ambiguity. With the new interface, whether to collect variadic arguments into an
+array, capture arguments by name into an object, or just pass the sole value
+argument is decided by a second parameter to `denodeify`. Omitted, you get the
+usual Node.js style callback. With `true`, you get variadic arguments. With an
+array of names, the arguments will be captured on an object literal with their
+respective name.

+
+The `makeNodeResolver` function has been deprecated and no longer supports the
+implicit variadic behavior.

 These have migration shims that simply throw errors.
