things you should know about contributing:

1.  API changes require discussion, use cases, etc. Code comes later.
2.  Pull requests are great for small fixes for bugs, documentation, etc.
3.  Pull requests are not merged directly into the master branch.
4.  Code contributions require signing a Google CLA.

API changes
-----------

We make changes to Guava's public [APIs][], including adding new APIs, very

 * change between Java releases.

 * <p><b>Warning:</b> Chunks of data that are put into the {@link Hasher} are not delimited. The
 * resulting {@link HashCode} is dependent only on the bytes inserted, and the order in which they
 * were inserted, not how those bytes were chunked into discrete put() operations. For example, the
 * following three expressions all generate colliding hash codes:
 *
 * <pre>{@code
