 **Solution**: In most cases it is sufficient to change all occurrences of `.pipe()` to `.then()`. Ensure that you aren't relying on context/state propagation (e.g., using `this`) or synchronous callback invocation, which were dropped from `.then()` for Promises/A+ interoperability as of jQuery 3.0.
 
+### JQMIGRATE: jQuery.fx.interval is deprecated
+
+**Cause**: As of jQuery 3.0 the `jQuery.fx.interval` property can be used to change the animation interval _only_ on browsers that do not support the `window.requestAnimationFrame()` method. That is currently only Internet Explorer 9 and the Android Browser. Once support is dropped for these browsers, the property will serve no purpose and it will be removed.
+
+**Solution**: Find and remove code that changes or uses `jQuery.fx.interval`. If the value is being used by code in your page or a plugin, the code may be making assumptions that are no longer valid. The default value of `jQuery.fx.interval` is `13` (milliseconds), which could be used instead of accessing this property.
+
 ### JQMIGRATE: jQuery.fn.andSelf() is deprecated and removed, use jQuery.fn.addBack()
 
 **Cause**: The `.andSelf()` method has been renamed to `.addBack()` as of jQuery 1.9 to better reflect its purpose of adding back the previous set of results. The old alias was removed in jQuery 3.0.
