=====
:release-date: 2016-04-21 01:30 P.M PDT
:release-by: Ask Solem

- :meth:`promise.throw() <vine.promises.promise.throw>` now passes partial
  args/kwargs to the errback:

    .. code-block:: pycon

        >>> p = promise(args=(self,), on_error=handle_error)
        >>> p.throw(exc)  # --> handle_error(self, exc)

- New :class:`vine.abstract.ThenableProxy` can be used to add
  promise-capabilities to a class by forwarding to a different promise.

    .. code-block:: python

        from vine import promise
        from vine.abstract import ThenableProxy

        class P(ThenableProxy):

            def __init__(self, on_success=None, on_error=None):
                self._set_promise_target(promise(
                    args=(self,), callback=on_success, on_error=on_error,
                ))

        p = P()
        p.then(download_file(url)).then(extract_file)

- :meth:`promise.throw() <vine.promises.promise.throw>` now supports a propagate
  argument that can be set to False to never reraise the exception.

- :meth:`promise.throw() <vine.promises.promise.throw>` now also reraises the
  current exception from the stack, if the exc argument is passed and that
  value is the same as the current exception.

- :meth:`Thenable.register() <vine.abstract.Thenable.register>` can now be
  used as a decorator.

- Argument to :meth:`promise.throw1(exc) <vine.promises.promise.throw1>` can now be
  :const:`None` to use the current exception.

- ``monotonic()`` now uses ``librt.so.0`` as an alternative if ``librt.so.1``
  does not exist.
