#What's new in 2.0

- [Resource management](API.md#resource-management) - never leak resources again
- [Promisification](API.md#promisification) on steroids - entire modules can now be promisified with one line of code
- [`.map()`](API.md#mapfunction-mapper--object-options---promise), [`.each()`](API.md#eachfunction-iterator---promise), [`.filter()`](API.md#filterfunction-filterer--object-options---promise), [`.reduce()`](API.md#reducefunction-reducer--dynamic-initialvalue---promise) reimagined from simple sugar to powerful concurrency coordination tools
- [API Documentation](API.md) has been reorganized and more elaborate examples added
- Deprecated [progression](#progression-migration) and [deferreds](#deferred-migration)
- Improved performance and readability

Features:

- Added [`using()`](API.md#promiseusingpromisedisposer-promise-promisedisposer-promise--function-handler---promise) and [`disposer()`](API.md#disposerfunction-disposer---disposer)
- [`.map()`](API.md#mapfunction-mapper--object-options---promise) now calls the handler as soon as items in the input array become fulfilled
- Added a concurrency option to [`.map()`](API.md#mapfunction-mapper--object-options---promise)
- [`.filter()`](API.md#filterfunction-filterer--object-options---promise) now calls the handler as soon as items in the input array become fulfilled
- Added a concurrency option to [`.filter()`](API.md#filterfunction-filterer--object-options---promise)
- [`.reduce()`](API.md#reducefunction-reducer--dynamic-initialvalue---promise) now calls the handler as soon as items in the input array become fulfilled, but in-order
- Added [`.each()`](API.md#eachfunction-iterator---promise)
- [`Promise.resolve()`](API.md#promiseresolvedynamic-value---promise) behaves like `Promise.cast`. `Promise.cast` deprecated.
- [Synchronous inspection](API.md#synchronous-inspection): Removed `.inspect()`, added [`.value()`](API.md#value---dynamic) and [`.reason()`](API.md#reason---dynamic)
- [`Promise.join()`](API.md#promisejoinpromisethenablevalue-promises-function-handler---promise) now takes a function as the last argument
- Added [`Promise.setScheduler()`](API.md#promisesetschedulerfunction-scheduler---void)
- [`.cancel()`](API.md#cancelerror-reason---promise) supports a custom cancellation reason
- [`.timeout()`](API.md#timeoutint-ms--string-message---promise) now cancels the promise instead of rejecting it
- [`.nodeify()`](API.md#nodeifyfunction-callback--object-options---promise) now supports passing multiple success results when mapping promises to nodebacks
- Added `suffix` and `filter` options to [`Promise.promisifyAll()`](API.md#promisepromisifyallobject-target--object-options---object)

Breaking changes:

- Sparse array holes are not skipped by collection methods but treated as existing elements with `undefined` value
- `.map()` and `.filter()` do not call the given mapper or filterer function in any specific order
- Removed the `.inspect()` method
- Yielding an array from a coroutine is not supported by default. You can use [`coroutine.addYieldHandler()`](API.md#promisecoroutineaddyieldhandlerfunction-handler---void) to configure the old behavior (or any behavior you want).
- [`.any()`](API.md#any---promise) and [`.some()`](API.md#someint-count---promise) no longer use an array as the rejection reason. [`AggregateError`](API.md#aggregateerror) is used instead.

Bugfixes:

 - Fix [#165](https://github.com/petkaantonov/bluebird/issues/165)
 - Fix [#166](https://github.com/petkaantonov/bluebird/issues/166)

## 1.1.1 (2014-03-18)

Bugfixes:

 - [#138](https://github.com/petkaantonov/bluebird/issues/138)

Features:

 - Possibly unhandled rejection handler will always get a stack trace, even if the rejection or thrown error was not an error
 - Unhandled rejections are tracked per promise, not per error. So if you create multiple branches from a single ancestor and that ancestor gets rejected, each branch with no error handler with the end will cause a possibly unhandled rejection handler invocation

 - You may now return promises and thenables from the filterer function used in `Promise.filter` and `Promise.prototype.filter`.

 - `.error()` now catches additional sources of rejections:

    - Rejections originating from `Promise.reject`

    - Rejections originating from thenables using
    the `reject` callback

    - Rejections originating from promisified callbacks
    which use the `errback` argument

    - Rejections originating from `new Promise` constructor
    where the `reject` callback is called explicitly

    - Rejections originating from `PromiseResolver` where
