2.5.0 (2016-12-22)

• 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).
