 ### Examples
 
-Word of caution: starting with marshmallow 3.0.0b7, `.dump()` now directly returns
-`data` instead of `(error, data)`, as noted in [marshmallow's changelog](https://github.com/marshmallow-code/marshmallow/blob/8cf1fb8d95f287d626ed0f38967c90198e28b476/CHANGELOG.rst#300b7-2018-02-03).
-marshmallow-jsonschema is directly affected by this and the examples below are
-for marshmallow<=3.0.0b7. To upgrade to >=3.0.0b7, remove the `.data` from the code.
+Note that while these examples are using marshmallow v3 API, marshmallow v2 is
+also still supported and part of the build. Support will be dropped for v2 in a future release.
