Release notes: * Lowered requirements from JDK 8 to JDK 7 for Mac users. * Now an error for a rule to have runtime_deps that are neverlink. * Allow creating on-the-fly repositories with new_local_repository(). * A (limited) build encyclopedia can be dynamically generated by running `bazel build src/main/java:gen_buildencyclopedia`. * Added a [getting started guide](https://github.com/google/bazel/blob/master/docs/getting-started.md).
