+# v3.1.0

+- Added `q.pushAsync` and `q.unshiftAsync`, analagous to `q.push` and `q.unshift`, except they always do not accept a callback, and reject if processing the task errors. (#1659)
+- Promises returned from `q.push` and `q.unshift` when a callback is not passed now resolve even if an error ocurred. (#1659)
+- Fixed a parsing bug in `autoInject` with complicated function bodies (#1663)
+- Added ES6+ configuration for Browserify bundlers (#1653)

@@ -11,0 +15,0 @@ Async is a utility module which provides straight-forward, powerful functions for working with [asynchronous JavaScript](http://caolan.github.io/async/global.html). Although originally designed for use with [Node.js](https://nodejs.org/) and installable via `npm install async`, it can also be used directly in the browser.  A ESM version is included in the main `async` package that should automatically be used with compatible bundlers such as Webpack and Rollup.
