(parallel/promises) Updated 1.0.1 to 1.2.0.1

promises 1.2.0.1
==============

* Added `future_promise()` which returns a `promise` that executes the
  expression using `future::future()`. `future_promise()` should
  (typically) be a drop-in replacement for any `future::future()`
  function call. `future_promise()` will not execute `future` work
  faster than `future::future()`, but `future_promise()` will only
  submit `future` jobs if a worker is available. If no workers are
  available, `future_promise()` will hold the expression information
  in a `promise` until a worker does become available to better take
  advantage of computing resources available to the main R
  session. For more information, please see the [`future_promise()`
  article](https://rstudio.github.io/promises/articles/future_promise.html). (#62)

* Added visibility support for `Promise$then(onFulfilled)`. (#59)

promises 1.1.1
==============

* Fix handling of FutureErrors during `future::resolved()` and
  `future::value()` by discarding the corrupt future. (#37)

promises 1.1.0
==============

* Fixed #49: `promise_all()` previously did not handle `NULL` values correctly. \ 
(#50))

* `new_promise_domain` now takes a `wrapOnFinally` argument, which can
  be used to intercept registration of `finally()`. Previous versions
  treated `finally` as passing the same callback to
  `then(onFulfilled=..., onRejected=...)`, and ignoring the result;
  for backward compatibility, promise domains will still treat
  `finally` that way by default (i.e. if `wrapOnFinally` is `NULL`,
  then `finally` will result in `wrapOnFulfilled` and `wrapOnRejected`
  being called, but if `wrapOnFinally` is provided then only
  `wrapOnFinally` will be called). (#43)
