@@ -25,6 +25,7 @@ Another theme is performance. We have eliminated internal deferrals in all cases
 - Async is also available as a collection of ES2015 modules in the new `async-es` package. (`import {forEachSeries} from 'async-es'`) (#984, #996)
 - Added `race`, analogous to `Promise.race()`. It will run an array of async tasks in parallel and will call its callback with the result of the first task to respond. (#568, #1038)
 - Collection methods now accept ES2015 iterators.  Maps, Sets, and anything that implements the iterator spec can now be passed directly to `each`, `map`, `parallel`, etc.. (#579, #839, #1074)
+- Added `mapValues`, for mapping over the properties of an object and returning an object with the same keys. (#1157, #1177)
 - Added `timeout`, a wrapper for an async function that will make the task time-out after the specified time. (#1007, #1027)
 - Added `reflect` and `reflectAll`, analagous to [`Promise.reflect()`](http://bluebirdjs.com/docs/api/reflect.html), a wrapper for async tasks that always succeeds, by gathering results and errors into an object.  (#942, #1012, #1095)
 - `constant` supports dynamic arguments -- it will now always use its last argument as the callback. (#1016, #1052)

 - Calling a callback more than once is considered an error, and an error will be thrown. This had an explicit breaking change in `waterfall`. If you were relying on this behavior, you should more accurately represent your control flow as an event emitter or stream. (#814, #815, #1048, #1050)
 - `auto` task functions now always take the callback as the last argument. If a task has dependencies, the `results` object will be passed as the first argument. To migrate old task functions, wrap them with [`_.flip`](https://lodash.com/docs#flip) (#1036, #1042)
 - Internal `setImmediate` calls have been refactored away. This may make existing flows vulnerable to stack overflows if you use many synchronous functions in series. Use `ensureAsync` to work around this. (#696, #704, #1049, #1050)
+- `map` used to return an object when iterating over an object.  `map` now always returns an array, like in other libraries.  The previous object behavior has been split out into `mapValues`. (#1157, #1177)
 - `filter`, `reject`, `some`, `every`, and related functions now expect an error as the first callback argument, rather than just a simple boolean. Pass `null` as the first argument, or use `fs.access` instead of `fs.exists`. (#118, #774, #1028, #1041)
 - `{METHOD}` and `{METHOD}Series` are now implemented in terms of `{METHOD}Limit`. This is a major internal simplification, and is not expected to cause many problems, but it does subtly affect how functions execute internally. (#778, #847)
 - `retry`'s callback is now optional. Previously, omitting the callback would partially apply the function, meaning it could be passed directly as a task to `series` or `auto`. The partially applied "control-flow" behavior has been separated out into `retryable`. (#1054, #1058)
