 * Unreleased
+* 1.3.0 (2022-03-28)
     * Add support for `EXTRA_CPPFLAGS`, similar to `EXTRA_CXXFLAGS`.
     * Add `digitalReadValue(pin, val)` to control the return value of
       `digitalRead(pin)`.

           `digitalReadValue()` is a no-op.
         * See [PR#61](https://github.com/bxparks/EpoxyDuino/pull/61).

 If your program has limited hardware dependencies so that it is conceptually
 portable to a vanilla Unix environment, EpoxyDuino may work well for you.
