v2.5.0

• Revert automatic cancellation of pending collection promises once the output promise resolves. This was introduced in 42d86b7 (PR #36, released in v2.3.0) and was both unintended and backward incompatible.

  If you need automatic cancellation, you can use something like:

  function allAndCancel(array $promises)
  {
       return \React\Promise\all($promises)
           ->always(function() use ($promises) {
               foreach ($promises as $promise) {
                   if ($promise instanceof \React\Promise\CancellablePromiseInterface) {
                       $promise->cancel();
                   }
               }
          });
  }

• all() and map() functions now preserve the order of the array (#77).

• Fix circular references when resolving a promise with itself (#71).
