+# v2.0.1
+
+- Significantly optimized all iteration based collection methods such as `each`, `map`, `filter`, etc (#1245, #1246, #1247).
+
+# v2.0.0
+
+Lots of changes here!
+
+First and foremost, we have a slick new [site for docs](https://caolan.github.io/async/). Special thanks to [**@hargasinski**](https://github.com/hargasinski) for his work converting our old docs to `jsdoc` format and implementing the new website. Also huge ups to [**@ivanseidel**](https://github.com/ivanseidel) for designing our new logo. It was a long process for both of these tasks, but I think these changes turned out extraordinary well.
+
+The biggest feature is modularization. You can now `require("async/series")` to only require the `series` function. Every Async library function is available this way. You still can `require("async")` to require the entire library, like you could do before.
+
+We also provide Async as a collection of ES2015 modules. You can now `import {each} from 'async-es'` or `import waterfall from 'async-es/waterfall'`. If you are using only a few Async functions, and are using a ES bundler such as Rollup, this can significantly lower your build size.
+
+Major thanks to [**@Kikobeats**](github.com/Kikobeats), [**@aearly**](github.com/aearly) and [**@megawac**](github.com/megawac) for doing the majority of the modularization work, as well as [**@jdalton**](github.com/jdalton) and [**@Rich-Harris**](github.com/Rich-Harris) for advisory work on the general modularization strategy.
+
+Another one of the general themes of the 2.0 release is standardization of what an "async" function is. We are now more strictly following the node-style continuation passing style. That is, an async function is a function that:
+
+1. Takes a variable number of arguments
+2. The last argument is always a callback
+3. The callback can accept any number of arguments
+4. The first argument passed to the callback will be treated as an error result, if the argument is truthy
+5. Any number of result arguments can be passed after the "error" argument
+6. The callback is called once and exactly once, either on the same tick or later tick of the JavaScript event loop.
+
+There were several cases where Async accepted some functions that did not strictly have these properties, most notably `auto`, `every`, `some`, and `filter`.
+
+Another theme is performance. We have eliminated internal deferrals in all cases where they make sense. For example, in `waterfall` and `auto`, there was a `setImmediate` between each task -- these deferrals have been removed. A `setImmediate` call can add up to 1ms of delay. This might not seem like a lot, but it can add up if you are using many Async functions in the course of processing a HTTP request, for example. Nearly all asynchronous functions that do I/O already have some sort of deferral built in, so the extra deferral is unnecessary. The trade-off of this change is removing our built-in stack-overflow defense. Many synchronous callback calls in series can quickly overflow the JS call stack. If you do have a function that is sometimes synchronous (calling its callback on the same tick), and are running into stack overflows, wrap it with `async.ensureAsync()`.
+
+Another big performance win has been re-implementing `queue`, `cargo`, and `priorityQueue` with [doubly linked lists](https://en.wikipedia.org/wiki/Doubly_linked_list) instead of arrays. This has lead to queues being an order of [magnitude faster on large sets of tasks](https://github.com/caolan/async/pull/1205).
+
+## New Features
+
+- Async is now modularized. Individual functions can be `require()`d from the main package. (`require('async/auto')`) (#984, #996)
+- 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)
+- `setImmediate` and `nextTick` now support arguments to partially apply to the deferred function, like the node-native versions do. (#940, #1053)
+- `auto` now supports resolving cyclic dependencies using [Kahn's algorithm](https://en.wikipedia.org/wiki/Topological_sorting#Kahn.27s_algorithm) (#1140).
+- Added `autoInject`, a relative of `auto` that automatically spreads a task's dependencies as arguments to the task function. (#608, #1055, #1099, #1100)
+- You can now limit the concurrency of `auto` tasks. (#635, #637)
+- Added `retryable`, a relative of `retry` that wraps an async function, making it retry when called. (#1058)
+- `retry` now supports specifying a function that determines the next time interval, useful for exponential backoff, logging and other retry strategies. (#1161)
+- `retry` will now pass all of the arguments the task function was resolved with to the callback (#1231).
+- Added `q.unsaturated` -- callback called when a `queue`'s number of running workers falls below a threshold. (#868, #1030, #1033, #1034)
+- Added `q.error` -- a callback called whenever a `queue` task calls its callback with an error. (#1170)
+- `applyEach` and `applyEachSeries` now pass results to the final callback. (#1088)
+
+## Breaking changes
+
+- 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)
+- The test function for `whilst`, `until`, and `during` used to be passed non-error args from the iteratee function's callback, but this led to weirdness where the first call of the test function would be passed no args. We have made it so the test function is never passed extra arguments, and only the `doWhilst`, `doUntil`, and `doDuring` functions pass iteratee callback arguments to the test function (#1217, #1224)
+- The `q.tasks` array has been renamed `q._tasks` and is now implemented as a doubly linked list (DLL). Any code that used to interact with this array will need to be updated to either use the provided helpers or support DLLs (#1205).
+- The timing of the `q.saturated()` callback in a `queue` has been modified to better reflect when tasks pushed to the queue will start queueing. (#724, #1078)
+- Removed `iterator` method in favour of [ES2015 iterator protocol](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Iterators_and_Generators ) which natively supports arrays (#1237)
+- Dropped support for Component, Jam, SPM, and Volo (#1175, ##176)
+
+## Bug Fixes
+
+- Improved handling of no dependency cases in `auto` & `autoInject` (#1147).
+- Fixed a bug where the callback generated by `asyncify` with  `Promises` could resolve twice (#1197).
+- Fixed several documented optional callbacks not actually being optional (#1223).
+
+## Other
+
+- Added `someSeries` and `everySeries` for symmetry, as well as a complete set of `any`/`anyLimit`/`anySeries` and `all`/`/allLmit`/`allSeries` aliases.
+- Added `find` as an alias for `detect. (as well as `findLimit` and `findSeries`).
+- Various doc fixes (#1005, #1008, #1010, #1015, #1021, #1037, #1039, #1051, #1102, #1107, #1121, #1123, #1129, #1135, #1138, #1141, #1153, #1216, #1217, #1232, #1233, #1236, #1238)
+
+Thank you [**@aearly**](github.com/aearly) and [**@megawac**](github.com/megawac) for taking the lead on version 2 of async.

+ * will stop. Further tasks will not execute (so any other functions depending
+ * on it will not run), and the main `callback` is immediately called with the
+ * error.
+ *
+ * Functions also receive an object containing the results of functions which
+ * have completed so far as the first argument, if they have dependencies. If a
+ * task function has no dependencies, it will only be passed a callback.

+ * @param {Object} tasks - An object. Each of its properties is either a

+ * in the array. The object's key of a property serves as the name of the task
+ * defined by that property, i.e. can be used when specifying requirements for
+ * other tasks. The function receives one or two arguments:
+ * * a `results` object, containing the results of the previously executed
+ *   functions, only passed if the task has any dependencies,
+ * * a `callback(err, result)` function, which must be called when finished,
+ *   passing an `error` (which can be `null`) and the result of the function's
+ *   execution.
+ * @param {number} [concurrency=Infinity] - An optional `integer` for
+ * determining the maximum number of tasks that can be run in parallel. By
+ * default, as many as possible.
+ * @param {Function} [callback] - An optional callback which is called when all
+ * the tasks have been completed. It receives the `err` argument if any `tasks`
+ * pass an error to their callback. Results are always returned; however, if an
+ * error occurs, no further `tasks` will be performed, and the results object
+ * will only contain partial results. Invoked with (err, results).

+/**
+ * A dependency-injected version of the [async.auto]{@link module:ControlFlow.auto} function. Dependent
+ * tasks are specified as parameters to the function, after the usual callback
+ * parameter, with the parameter names matching the names of the tasks it
+ * depends on. This can provide even more readable task graphs which can be
+ * easier to maintain.
+ *
+ * If a final callback is specified, the task results are similarly injected,
+ * specified as named parameters after the initial error parameter.
+ *
+ * The autoInject function is purely syntactic sugar and its semantics are
+ * otherwise equivalent to [async.auto]{@link module:ControlFlow.auto}.
+ *
+ * @name autoInject
+ * @static
+ * @memberOf module:ControlFlow
+ * @method
+ * @see [async.auto]{@link module:ControlFlow.auto}
+ * @category Control Flow
+ * @param {Object} tasks - An object, each of whose properties is a function of
+ * the form 'func([dependencies...], callback). The object's key of a property
+ * serves as the name of the task defined by that property, i.e. can be used
+ * when specifying requirements for other tasks.
+ * * The `callback` parameter is a `callback(err, result)` which must be called
+ *   when finished, passing an `error` (which can be `null`) and the result of
+ *   the function's execution. The remaining parameters name other tasks on
+ *   which the task is dependent, and the results from those tasks are the
+ *   arguments of those parameters.
+ * @param {Function} [callback] - An optional callback which is called when all
+ * the tasks have been completed. It receives the `err` argument if any `tasks`
+ * pass an error to their callback, and a `results` object with any completed
+ * task results, similar to `auto`.
+ * @example
+ *
+ * //  The example from `auto` can be rewritten as follows:
+ * async.autoInject({
+ *     get_data: function(callback) {
+ *         // async code to get some data
+ *         callback(null, 'data', 'converted to array');
+ *     },
+ *     make_folder: function(callback) {
+ *         // async code to create a directory to store a file in
+ *         // this is run at the same time as getting the data
+ *         callback(null, 'folder');
+ *     },
+ *     write_file: function(get_data, make_folder, callback) {
+ *         // once there is some data and the directory exists,
+ *         // write the data to a file in the directory
+ *         callback(null, 'filename');
+ *     },
+ *     email_link: function(write_file, callback) {
+ *         // once the file is written let's email a link to it...
+ *         // write_file contains the filename returned by write_file.
+ *         callback(null, {'file':write_file, 'email':'user@example.com'});
+ *     }
+ * }, function(err, results) {
+ *     console.log('err = ', err);
+ *     console.log('email_link = ', results.email_link);
+ * });
+ *
+ * // If you are using a JS minifier that mangles parameter names, `autoInject`
+ * // will not work with plain functions, since the parameter names will be
+ * // collapsed to a single letter identifier.  To work around this, you can
+ * // explicitly specify the names of the parameters your task function needs
+ * // in an array, similar to Angular.js dependency injection.
+ *
+ * // This still has an advantage over plain `auto`, since the results a task
+ * // depends on are still spread into arguments.
+ * async.autoInject({
+ *     //...
+ *     write_file: ['get_data', 'make_folder', function(get_data, make_folder, callback) {

+ * @typedef {Object} CargoObject
+ * @memberOf module:ControlFlow
+ * @property {Function} length - A function returning the number of items
+ * waiting to be processed. Invoke like `cargo.length()`.
+ * @property {number} payload - An `integer` for determining how many tasks
+ * should be process per round. This property can be changed after a `cargo` is
+ * created to alter the payload on-the-fly.
+ * @property {Function} push - Adds `task` to the `queue`. The callback is
+ * called once the `worker` has finished processing the task. Instead of a
+ * single task, an array of `tasks` can be submitted. The respective callback is
+ * used for every task in the list. Invoke like `cargo.push(task, [callback])`.
+ * @property {Function} saturated - A callback that is called when the
+ * `queue.length()` hits the concurrency and further tasks will be queued.
+ * @property {Function} empty - A callback that is called when the last item
+ * from the `queue` is given to a `worker`.
+ * @property {Function} drain - A callback that is called when the last item
+ * from the `queue` has returned from the `worker`.
+ * @property {Function} idle - a function returning false if there are items
+ * waiting or being processed, or true if not. Invoke like `cargo.idle()`.
+ * @property {Function} pause - a function that pauses the processing of tasks
+ * until `resume()` is called. Invoke like `cargo.pause()`.
+ * @property {Function} resume - a function that resumes the processing of
+ * queued tasks when the queue is paused. Invoke like `cargo.resume()`.
+ * @property {Function} kill - a function that removes the `drain` callback and
+ * empties remaining tasks from the queue forcing it to go idle. Invoke like `cargo.kill()`.

+# lodash v4.16.4
+
+The [Lodash](https://lodash.com/) library exported as [Node.js](https://nodejs.org/) modules.
+
+## Installation
+
+Using npm:
+```shell
+$ npm i -g npm
+$ npm i --save lodash
+```
+
+In Node.js:
+```js
+// Load the full build.
+var _ = require('lodash');
+// Load the core build.
+var _ = require('lodash/core');
+// Load the FP build for immutable auto-curried iteratee-first data-last methods.
+var fp = require('lodash/fp');
+
+// Load method categories.
+var array = require('lodash/array');
+var object = require('lodash/fp/object');
+
+// Cherry-pick methods for smaller browserify/rollup/webpack bundles.
+var at = require('lodash/at');
+var curryN = require('lodash/fp/curryN');
+```
+
+See the [package source](https://github.com/lodash/lodash/tree/4.16.4-npm) for more details.
+
+**Note:**<br>
+Install [n_](https://www.npmjs.com/package/n_) for Lodash use in the Node.js < 6 REPL.
+
+## Support

+   * or may return a primitive value will automatically end the chain sequence
+   * and return the unwrapped value. Otherwise, the value must be unwrapped

+   *
+   * Explicit chain sequences, which must be unwrapped with `_#value`, may be

+   * The execution of chained methods is lazy, that is, it's deferred until

+   *
+   * Lazy evaluation allows several methods to support shortcut fusion.
+   * Shortcut fusion is an optimization to merge iteratee calls; this avoids
+   * the creation of intermediate arrays and can greatly reduce the number of

+   * fusion if the section is applied to an array of at least `200` elements
+   * and any iteratees accept only one argument. The heuristic for whether a
+   * section qualifies for shortcut fusion is subject to change.

+   * Chaining is supported in custom builds as long as the `_#value` method is
+   * directly or indirectly included in the build.
+   *
+   * In addition to lodash methods, wrappers have `Array` and `String` methods.

+   * `tail`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, and `toArray`
+   *
+   * The chainable wrapper methods are:

+     * Creates a `lodash` object which wraps `value` to enable implicit method
+     * chain sequences. Methods that operate on and return arrays, collections,
+     * and functions can be chained together. Methods that retrieve a single value
+     * or may return a primitive value will automatically end the chain sequence
+     * and return the unwrapped value. Otherwise, the value must be unwrapped
+     * with `_#value`.
+     *
+     * Explicit chain sequences, which must be unwrapped with `_#value`, may be
+     * enabled using `_.chain`.
+     *
+     * The execution of chained methods is lazy, that is, it's deferred until
+     * `_#value` is implicitly or explicitly called.
+     *
+     * Lazy evaluation allows several methods to support shortcut fusion.
+     * Shortcut fusion is an optimization to merge iteratee calls; this avoids
+     * the creation of intermediate arrays and can greatly reduce the number of
+     * iteratee executions. Sections of a chain sequence qualify for shortcut
+     * fusion if the section is applied to an array of at least `200` elements
+     * and any iteratees accept only one argument. The heuristic for whether a
+     * section qualifies for shortcut fusion is subject to change.
+     *
+     * Chaining is supported in custom builds as long as the `_#value` method is
+     * directly or indirectly included in the build.
+     *
+     * In addition to lodash methods, wrappers have `Array` and `String` methods.

+ * and functions can be chained together. Methods that retrieve a single value
+ * or may return a primitive value will automatically end the chain sequence
+ * and return the unwrapped value. Otherwise, the value must be unwrapped
+ * with `_#value`.
+ *
+ * Explicit chain sequences, which must be unwrapped with `_#value`, may be
+ * enabled using `_.chain`.
+ *
+ * The execution of chained methods is lazy, that is, it's deferred until
+ * `_#value` is implicitly or explicitly called.
+ *
+ * Lazy evaluation allows several methods to support shortcut fusion.
+ * Shortcut fusion is an optimization to merge iteratee calls; this avoids
+ * the creation of intermediate arrays and can greatly reduce the number of
+ * iteratee executions. Sections of a chain sequence qualify for shortcut
+ * fusion if the section is applied to an array of at least `200` elements
+ * and any iteratees accept only one argument. The heuristic for whether a
+ * section qualifies for shortcut fusion is subject to change.
+ *
+ * Chaining is supported in custom builds as long as the `_#value` method is
+ * directly or indirectly included in the build.
+ *
+ * In addition to lodash methods, wrappers have `Array` and `String` methods.
+ *
+ * The wrapper `Array` methods are:
+ * `concat`, `join`, `pop`, `push`, `shift`, `sort`, `splice`, and `unshift`
