Version 0.1.7 * Add a `Future::shared` method for creating a future that can be shared amongst threads by cloning the future itself. All derivative futures will resolve to the same value once the original future has been resolved. * Add a `FutureFrom` trait for future-based conversion * Fix a wakeup bug in `Receiver::close` * Add `future::poll_fn` for quickly adapting a `Poll`-based function to a future. * Add an `Either` enum with two branches to easily create one future type based on two different futures created on two branches of control flow. * Remove the `'static` bound on `Unpark` * Optimize `send_all` and `forward` to send as many items as possible before calling `poll_complete`. * Unify the return types of the `ok`, `err`, and `result` future to assist returning different varieties in different branches of a function. * Add `CpuFuture::forget` to allow the computation to continue running after a drop. * Add a `stream::futures_unordered` combinator to turn a list of futures into a stream representing their order of completion.
