        New features:

          - --extra_entitlements allows passing additional entitlements for
            iOS signing
          - The output of -printconfiguration of proguard is available
            through an implicit "[target_name]_proguard.confg" output of
            android_binary (and
            java_binary).
          - Objective-C compiler information is now available to Skylark.

        Important changes:

          - ProGuard relies on bazel to check to see if the inputs have
            changed.
          - Build the jsonnet tool for the host when cross-compiling.
          - Add ProductType for watch OS 1 extension and application.
          - Restrict file types used for "entitlements" attribute to
            [".entitlements", ".plist"]
          - Restrict file types allowed for "strings" attribute to ".strings".
          - local_repository can take a relative path.
          - Support apple_watch1_extension and apple_watch_extension_binary
            rules for creating watch OS 1 extensions.
          - implement list.insert for skylark rule
          - Enable overriding attributes for Rust binaries.
          - ios_device attribute "xcode", for declaring a specific xcode to
            use when selecting iOS simulators.
