• Reversed decision from v5.1.3 and made it an optional config parameter: overwriteOnInitialValuesChange. If you want every change to initialValues to overwrite your values, like those of you in #832, you will need to set overwriteOnInitialValuesChange: false. Otherwise, every time the initialValues prop changes, whether or not the form has been initialized already, the values, as well as the initialValues with which dirty/pristine is calculated, will be overwritten.
