+## 1.5.1
+
+ - Q.any now annotates its error message to clarify that Q.any was involved and
+   includes only the last error emitted. (Ivan Etchart)
+ - Avoid domain.dispose during tests in preparation for Node.js 9. (Anna
+   Henningsen)
+
+## 1.5.0
+
+ - Q.any gives an error message from the last rejected promise
+ - Throw if callback supplied to "finally" is invalid (@grahamrhay)
+ - Long stack trace improvements, can now construct long stack traces
+   across rethrows.
+
+## 1.4.1
+
+ - Address an issue that prevented Q from being used as a `<script>` for
+   Firefox add-ons. Q can now be used in any environment that provides `window`
+   or `self` globals, favoring `window` since add-ons have an an immutable
+   `self` that is distinct from `window`.
+
+## 1.4.0
+
+ - Add `noConflict` support for use in `<script>` (@jahnjw).
+
+## 1.3.0
+
+ - Add tracking for unhandled and handled rejections in Node.js (@benjamingr).
+
+## 1.2.1
+
+ - Fix Node.js environment detection for modern Browserify (@kahnjw).
+
+## 1.2.0
+
+ - Added Q.any(promisesArray) method (@vergara).
+   Returns a promise fulfilled with the value of the first resolved promise in
+   promisesArray. If all promises in promisesArray are rejected, it returns
+   a rejected promise.
+
+## 1.1.2
+
+ - Removed extraneous files from the npm package by using the "files"
+   whitelist in package.json instead of the .npmignore blacklist.
+   (@anton-rudeshko)
+
+## 1.1.1
+
+ - Fix a pair of regressions in bootstrapping, one which precluded
+   WebWorker support, and another that precluded support in
+   ``<script>`` usage outright. #607
+
+## 1.1.0
+
+ - Adds support for enabling long stack traces in node.js by setting
+   environment variable `Q_DEBUG=1`.
+ - Introduces the `tap` method to promises, which will see a value
+   pass through without alteration.
+ - Use instanceof to recognize own promise instances as opposed to
+   thenables.
+ - Construct timeout errors with `code === ETIMEDOUT` (Kornel Lesiński)
+ - More descriminant CommonJS module environment detection.
+ - Dropped continuous integration for Node.js 0.6 and 0.8 because of
+   changes to npm that preclude the use of new `^` version predicate
+   operator in any transitive dependency.
+ - Users can now override `Q.nextTick`.
+
+## 1.0.1
+
+ - Adds support for `Q.Promise`, which implements common usage of the
+   ES6 `Promise` constructor and its methods. `Promise` does not have
+   a valid promise constructor and a proper implementation awaits
+   version 2 of Q.
+ - Removes the console stopgap for a promise inspector. This no longer
+   works with any degree of reliability.
+ - Fixes support for content security policies that forbid eval. Now
+   using the `StopIteration` global to distinguish SpiderMonkey
+   generators from ES6 generators, assuming that they will never
+   coexist.
+
+## 1.0.0
+
+:cake: This is all but a re-release of version 0.9, which has settled
+into a gentle maintenance mode and rightly deserves an official 1.0.
+An ambitious 2.0 release is already around the corner, but 0.9/1.0
+have been distributed far and wide and demand long term support.
+
+ - Q will now attempt to post a debug message in browsers regardless
+   of whether window.Touch is defined. Chrome at least now has this
+   property regardless of whether touch is supported by the underlying
+   hardware.
+ - Remove deprecation warning from `promise.valueOf`. The function is
+   called by the browser in various ways so there is no way to
+   distinguish usage that should be migrated from usage that cannot be
+   altered.
+
+## 0.9.7
+
+ - :warning: `q.min.js` is no longer checked-in.  It is however still
+   created by Grunt and NPM.
+ - Fixes a bug that inhibited `Q.async` with implementations of the new
+   ES6 generators.
+ - Fixes a bug with `nextTick` affecting Safari 6.0.5 the first time a
+   page loads when an `iframe` is involved.
+ - Introduces `passByCopy`, `join`, and `race`.
+ - Shows stack traces or error messages on the console, instead of
+   `Error` objects.
+ - Elimintates wrapper methods for improved performance.
+ - `Q.all` now propagates progress notifications of the form you might
+   expect of ES6 iterations, `{value, index}` where the `value` is the
+   progress notification from the promise at `index`.
+
+## 0.9.6
+
+ - Fixes a bug in recognizing the difference between compatible Q
+   promises, and Q promises from before the implementation of "inspect".
+   The latter are now coerced.
+ - Fixes an infinite asynchronous coercion cycle introduced by former
+   solution, in two independently sufficient ways.  1.) All promises
+   returned by makePromise now implement "inspect", albeit a default
+   that reports that the promise has an "unknown" state.  2.) The
+   implementation of "then/when" is now in "then" instead of "when", so
+   that the responsibility to "coerce" the given promise rests solely in
+   the "when" method and the "then" method may assume that "this" is a
+   promise of the right type.
+ - Refactors `nextTick` to use an unrolled microtask within Q regardless
+   of how new ticks a requested. #316 @rkatic
+
+## 0.9.5
+
+ - Introduces `inspect` for getting the state of a promise as
+   `{state: "fulfilled" | "rejected" | "pending", value | reason}`.
+ - Introduces `allSettled` which produces an array of promises states
+   for the input promises once they have all "settled".  This is in
+   accordance with a discussion on Promises/A+ that "settled" refers to
+   a promise that is "fulfilled" or "rejected".  "resolved" refers to a
+   deferred promise that has been "resolved" to another promise,
+   "sealing its fate" to the fate of the successor promise.
+ - Long stack traces are now off by default.  Set `Q.longStackSupport`
+   to true to enable long stack traces.
+ - Long stack traces can now follow the entire asynchronous history of a
+   promise, not just a single jump.
+ - Introduces `spawn` for an immediately invoked asychronous generator.
+   @jlongster
+ - Support for *experimental* synonyms `mapply`, `mcall`, `nmapply`,
+   `nmcall` for method invocation.
+
+## 0.9.4
+
+ - `isPromise` and `isPromiseAlike` now always returns a boolean
+   (even for falsy values). #284 @lfac-pt
+ - Support for ES6 Generators in `async` #288 @andywingo
+ - Clear duplicate promise rejections from dispatch methods #238 @SLaks
+ - Unhandled rejection API #296 @domenic
+   `stopUnhandledRejectionTracking`, `getUnhandledReasons`,
+   `resetUnhandledRejections`.
+
+## 0.9.3
+
+ - Add the ability to give `Q.timeout`'s errors a custom error message. #270
+   @jgrenon
+ - Fix Q's call-stack busting behavior in Node.js 0.10, by switching from
+   `process.nextTick` to `setImmediate`. #254 #259
+ - Fix Q's behavior when used with the Mocha test runner in the browser, since
+   Mocha introduces a fake `process` global without a `nextTick` property. #267
+ - Fix some, but not all, cases wherein Q would give false positives in its
+   unhandled rejection detection (#252). A fix for other cases (#238) is
+   hopefully coming soon.
+ - Made `Q.promise` throw early if given a non-function.
+
+## 0.9.2
+
+ - Pass through progress notifications when using `timeout`. #229 @omares
+ - Pass through progress notifications when using `delay`.
+ - Fix `nbind` to actually bind the `thisArg`. #232 @davidpadbury
+
+## 0.9.1
+
+ - Made the AMD detection compatible with the RequireJS optimizer's `namespace`
+   option. #225 @terinjokes
+ - Fix side effects from `valueOf`, and thus from `isFulfilled`, `isRejected`,
+   and `isPending`. #226 @benjamn
+
+## 0.9.0
+
+This release removes many layers of deprecated methods and brings Q closer to
+alignment with Mark Miller’s TC39 [strawman][] for concurrency. At the same
+time, it fixes many bugs and adds a few features around error handling. Finally,
+it comes with an updated and comprehensive [API Reference][].

+
+### Alignment with the Concurrency Strawman
+
+-   Q now exports a `Q(value)` function, an alias for `resolve`.
+    `Q.call`, `Q.apply`, and `Q.bind` were removed to make room for the
+    same methods on the function prototype.
+-   `invoke` has been aliased to `send` in all its forms.
+-   `post` with no method name acts like `fapply`.
+
+### Error Handling
+
+-   Long stack traces can be turned off by setting `Q.stackJumpLimit` to zero.
+    In the future, this property will be used to fine tune how many stack jumps
+    are retained in long stack traces; for now, anything nonzero is treated as
+    one (since Q only tracks one stack jump at the moment, see #144). #168
+-   In Node.js, if there are unhandled rejections when the process exits, they
+    are output to the console. #115
+
+### Other
+
+-   `delete` and `set` (née `put`) no longer have a fulfillment value.
+-   Q promises are no longer frozen, which
+    [helps with performance](http://code.google.com/p/v8/issues/detail?id=1858).
+-   `thenReject` is now included, as a counterpart to `thenResolve`.
+-   The included browser `nextTick` shim is now faster. #195 @rkatic.
+
+### Bug Fixes
+
+-   Q now works in Internet Explorer 10. #186 @ForbesLindesay
+-   `fbind` no longer hard-binds the returned function's `this` to `undefined`.
+    #202
+-   `Q.reject` no longer leaks memory. #148
+-   `npost` with no arguments now works. #207
+-   `allResolved` now works with non-Q promises ("thenables"). #179
+-   `keys` behavior is now correct even in browsers without native
+    `Object.keys`. #192 @rkatic
+-   `isRejected` and the `exception` property now work correctly if the
+    rejection reason is falsy. #198
+
+### Internals and Advanced
+
+-   The internal interface for a promise now uses
+    `dispatchPromise(resolve, op, operands)` instead of `sendPromise(op,
+    resolve, ...operands)`, which reduces the cases where Q needs to do
+    argument slicing.
+-   The internal protocol uses different operands. "put" is now "set".
+    "del" is now "delete". "view" and "viewInfo" have been removed.
+-   `Q.fulfill` has been added. It is distinct from `Q.resolve` in that
+    it does not pass promises through, nor coerces promises from other
+    systems. The promise becomes the fulfillment value. This is only
+    recommended for use when trying to fulfill a promise with an object that has
+    a `then` function that is at the same time not a promise.
+
+## 0.8.12
+- Treat foreign promises as unresolved in `Q.isFulfilled`; this lets `Q.all`
+  work on arrays containing foreign promises. #154
+- Fix minor incompliances with the [Promises/A+ spec][] and [test suite][]. #157
+  #158
+
+[Promises/A+ spec]: http://promises-aplus.github.com/promises-spec/
+[test suite]: https://github.com/promises-aplus/promises-tests
+
+## 0.8.11
+
+ - Added ``nfcall``, ``nfapply``, and ``nfbind`` as ``thisp``-less versions of
+   ``ncall``, ``napply``, and ``nbind``. The latter are now deprecated. #142
+ - Long stack traces no longer cause linearly-growing memory usage when chaining
+   promises together. #111
+ - Inspecting ``error.stack`` in a rejection handler will now give a long stack
+   trace. #103
+ - Fixed ``Q.timeout`` to clear its timeout handle when the promise is rejected;
+   previously, it kept the event loop alive until the timeout period expired.
+   #145 @dfilatov
+ - Added `q/queue` module, which exports an infinite promise queue
+   constructor.
+
+## 0.8.10
+
+ - Added ``done`` as a replacement for ``end``, taking the usual fulfillment,
+   rejection, and progress handlers. It's essentially equivalent to
+   ``then(f, r, p).end()``.
+ - Added ``Q.onerror``, a settable error trap that you can use to get full stack
+   traces for uncaught errors. #94
+ - Added ``thenResolve`` as a shortcut for returning a constant value once a
+   promise is fulfilled. #108 @ForbesLindesay
+ - Various tweaks to progress notification, including propagation and
+   transformation of progress values and only forwarding a single progress
+   object.
+ - Renamed ``nend`` to ``nodeify``. It no longer returns an always-fulfilled
+   promise when a Node callback is passed.
+ - ``deferred.resolve`` and ``deferred.reject`` no longer (sometimes) return
+   ``deferred.promise``.
+ - Fixed stack traces getting mangled if they hit ``end`` twice. #116 #121 @ef4
+ - Fixed ``ninvoke`` and ``npost`` to work on promises for objects with Node
+   methods. #134
+ - Fixed accidental coercion of objects with nontrivial ``valueOf`` methods,
+   like ``Date``s, by the promise's ``valueOf`` method. #135
+ - Fixed ``spread`` not calling the passed rejection handler if given a rejected
+   promise.
+
+## 0.8.9
+
+ - Added ``nend``
+ - Added preliminary progress notification support, via
+   ``promise.then(onFulfilled, onRejected, onProgress)``,
+   ``promise.progress(onProgress)``, and ``deferred.notify(...progressData)``.
+ - Made ``put`` and ``del`` return the object acted upon for easier chaining.
+   #84
+ - Fixed coercion cycles with cooperating promises. #106
+
+## 0.8.7
+
+ - Support [Montage Require](http://github.com/kriskowal/mr)
+
+## 0.8.6
+
+ - Fixed ``npost`` and ``ninvoke`` to pass the correct ``thisp``. #74
+ - Fixed various cases involving unorthodox rejection reasons. #73 #90
+   @ef4
+ - Fixed double-resolving of misbehaved custom promises. #75
+ - Sped up ``Q.all`` for arrays contain already-resolved promises or scalar
+   values. @ForbesLindesay
+ - Made stack trace filtering work when concatenating assets. #93 @ef4
+ - Added warnings for deprecated methods. @ForbesLindesay
+ - Added ``.npmignore`` file so that dependent packages get a slimmer
+   ``node_modules`` directory.
+
+## 0.8.5
+
+ - Added preliminary support for long traces (@domenic)
+ - Added ``fapply``, ``fcall``, ``fbind`` for non-thisp
+   promised function calls.
+ - Added ``return`` for async generators, where generators
+   are implemented.
+ - Rejected promises now have an "exception" property.  If an object
+   isRejected(object), then object.valueOf().exception will
+   be the wrapped error.
+ - Added Jasmine specifications
+ - Support Internet Explorers 7–9 (with multiple bug fixes @domenic)
+ - Support Firefox 12
+ - Support Safari 5.1.5
+ - Support Chrome 18
+
+## 0.8.4
+
+ - WARNING: ``promise.timeout`` is now rejected with an ``Error`` object
+   and the message now includes the duration of the timeout in
+   miliseconds.  This doesn't constitute (in my opinion) a
+   backward-incompatibility since it is a change of an undocumented and
+   unspecified public behavior, but if you happened to depend on the
+   exception being a string, you will need to revise your code.
+ - Added ``deferred.makeNodeResolver()`` to replace the more cryptic
+   ``deferred.node()`` method.
+ - Added experimental ``Q.promise(maker(resolve, reject))`` to make a
+   promise inside a callback, such that thrown exceptions in the
+   callback are converted and the resolver and rejecter are arguments.
+   This is a shorthand for making a deferred directly and inspired by
+   @gozala’s stream constructor pattern and the Microsoft Windows Metro
+   Promise constructor interface.
+ - Added experimental ``Q.begin()`` that is intended to kick off chains
+   of ``.then`` so that each of these can be reordered without having to
+   edit the new and former first step.
+
+## 0.8.3
+
+ - Added ``isFulfilled``, ``isRejected``, and ``isResolved``
+   to the promise prototype.
+ - Added ``allResolved`` for waiting for every promise to either be
+   fulfilled or rejected, without propagating an error. @utvara #53
+ - Added ``Q.bind`` as a method to transform functions that
+   return and throw into promise-returning functions. See
+   [an example](https://gist.github.com/1782808). @domenic
+ - Renamed ``node`` export to ``nbind``, and added ``napply`` to
+   complete the set. ``node`` remains as deprecated. @domenic #58
+ - Renamed ``Method`` export to ``sender``.  ``Method``
+   remains as deprecated and will be removed in the next
+   major version since I expect it has very little usage.
+ - Added browser console message indicating a live list of
+   unhandled errors.
+ - Added support for ``msSetImmediate`` (IE10) or ``setImmediate``
+   (available via [polyfill](https://github.com/NobleJS/setImmediate))
+   as a browser-side ``nextTick`` implementation. #44 #50 #59
+ - Stopped using the event-queue dependency, which was in place for
+   Narwhal support: now directly using ``process.nextTick``.
+ - WARNING: EXPERIMENTAL: added ``finally`` alias for ``fin``, ``catch``
+   alias for ``fail``, ``try`` alias for ``call``, and ``delete`` alias
+   for ``del``.  These properties are enquoted in the library for
+   cross-browser compatibility, but may be used as property names in
+   modern engines.
+
+## 0.8.2
+
+ - Deprecated ``ref`` in favor of ``resolve`` as recommended by
+   @domenic.
+ - Update event-queue dependency.
+
+## 0.8.1
+
+ - Fixed Opera bug. #35 @cadorn
+ - Fixed ``Q.all([])`` #32 @domenic
+
+## 0.8.0
+
+ - WARNING: ``enqueue`` removed.  Use ``nextTick`` instead.
+   This is more consistent with NodeJS and (subjectively)
+   more explicit and intuitive.
+ - WARNING: ``def`` removed.  Use ``master`` instead.  The
+   term ``def`` was too confusing to new users.
+ - WARNING: ``spy`` removed in favor of ``fin``.
+ - WARNING: ``wait`` removed. Do ``all(args).get(0)`` instead.
+ - WARNING: ``join`` removed. Do ``all(args).spread(callback)`` instead.
+ - WARNING: Removed the ``Q`` function module.exports alias
+   for ``Q.ref``. It conflicts with ``Q.apply`` in weird
+   ways, making it uncallable.
+ - Revised ``delay`` so that it accepts both ``(value,
+   timeout)`` and ``(timeout)`` variations based on
+   arguments length.
+ - Added ``ref().spread(cb(...args))``, a variant of
+   ``then`` that spreads an array across multiple arguments.
+   Useful with ``all()``.
+ - Added ``defer().node()`` Node callback generator.  The
+   callback accepts ``(error, value)`` or ``(error,
+   ...values)``.  For multiple value arguments, the
+   fulfillment value is an array, useful in conjunction with
+   ``spread``.
+ - Added ``node`` and ``ncall``, both with the signature
+   ``(fun, thisp_opt, ...args)``.  The former is a decorator
+   and the latter calls immediately.  ``node`` optional
+   binds and partially applies.  ``ncall`` can bind and pass
+   arguments.
+
+## 0.7.2
+
+ - Fixed thenable promise assimilation.
+
+## 0.7.1
+
+ - Stopped shimming ``Array.prototype.reduce``. The
+   enumerable property has bad side-effects.  Libraries that
+   depend on this (for example, QQ) will need to be revised.
+
+## 0.7.0 - BACKWARD INCOMPATIBILITY
+
+ - WARNING: Removed ``report`` and ``asap``
+ - WARNING: The ``callback`` argument of the ``fin``
+   function no longer receives any arguments. Thus, it can
+   be used to call functions that should not receive
+   arguments on resolution.  Use ``when``, ``then``, or
+   ``fail`` if you need a value.
+ - IMPORTANT: Fixed a bug in the use of ``MessageChannel``
+   for ``nextTick``.
+ - Renamed ``enqueue`` to ``nextTick``.
+ - Added experimental ``view`` and ``viewInfo`` for creating
+   views of promises either when or before they're
+   fulfilled.
+ - Shims are now externally applied so subsequent scripts or
+   dependees can use them.
+ - Improved minification results.
+ - Improved readability.
+
+## 0.6.0 - BACKWARD INCOMPATIBILITY
+
+ - WARNING: In practice, the implementation of ``spy`` and
+   the name ``fin`` were useful.  I've removed the old
+   ``fin`` implementation and renamed/aliased ``spy``.
+ - The "q" module now exports its ``ref`` function as a "Q"
+   constructor, with module systems that support exports
+   assignment including NodeJS, RequireJS, and when used as
+   a ``<script>`` tag. Notably, strictly compliant CommonJS
+   does not support this, but UncommonJS does.
+ - Added ``async`` decorator for generators that use yield
+   to "trampoline" promises. In engines that support
+   generators (SpiderMonkey), this will greatly reduce the
+   need for nested callbacks.
+ - Made ``when`` chainable.
+ - Made ``all`` chainable.
+
+## 0.5.3
+
+ - Added ``all`` and refactored ``join`` and ``wait`` to use
+   it.  All of these will now reject at the earliest
+   rejection.
+
+## 0.5.2
+
+ - Minor improvement to ``spy``; now waits for resolution of
+   callback promise.
+
+## 0.5.1
+
+ - Made most Q API methods chainable on promise objects, and
+   turned the previous promise-methods of ``join``,
+   ``wait``, and ``report`` into Q API methods.
+ - Added ``apply`` and ``call`` to the Q API, and ``apply``
+   as a promise handler.
+ - Added ``fail``, ``fin``, and ``spy`` to Q and the promise
+   prototype for convenience when observing rejection,
+   fulfillment and rejection, or just observing without
+   affecting the resolution.
+ - Renamed ``def`` (although ``def`` remains shimmed until
+   the next major release) to ``master``.
+ - Switched to using ``MessageChannel`` for next tick task
+   enqueue in browsers that support it.
+
+## 0.5.0 - MINOR BACKWARD INCOMPATIBILITY
+
+ - Exceptions are no longer reported when consumed.
+ - Removed ``error`` from the API.  Since exceptions are
+   getting consumed, throwing them in an errback causes the
+   exception to silently disappear.  Use ``end``.
+ - Added ``end`` as both an API method and a promise-chain
+   ending method.  It causes propagated rejections to be
+   thrown, which allows Node to write stack traces and
+   emit ``uncaughtException`` events, and browsers to
+   likewise emit ``onerror`` and log to the console.
+ - Added ``join`` and ``wait`` as promise chain functions,
+   so you can wait for variadic promises, returning your own
+   promise back, or join variadic promises, resolving with a
+   callback that receives variadic fulfillment values.
+
+## 0.4.4
+
+ - ``end`` no longer returns a promise. It is the end of the
+   promise chain.
+ - Stopped reporting thrown exceptions in ``when`` callbacks
+   and errbacks.  These must be explicitly reported through
+   ``.end()``, ``.then(null, Q.error)``, or some other
+   mechanism.
+ - Added ``report`` as an API method, which can be used as
+   an errback to report and propagate an error.
+ - Added ``report`` as a promise-chain method, so an error
+   can be reported if it passes such a gate.
+
+## 0.4.3
+
+ - Fixed ``<script>`` support that regressed with 0.4.2
+   because of "use strict" in the module system
+   multi-plexer.
+
+## 0.4.2
+
+ - Added support for RequireJS (jburke)
+
+## 0.4.1
+
+ - Added an "end" method to the promise prototype,
+   as a shorthand for waiting for the promise to
+   be resolved gracefully, and failing to do so,
+   to dump an error message.
+
+## 0.4.0 - BACKWARD INCOMPATIBLE*
+
+ - *Removed the utility modules. NPM and Node no longer
+   expose any module except the main module.  These have
+   been moved and merged into the "qq" package.
+ - *In a non-CommonJS browser, q.js can be used as a script.
+   It now creates a Q global variable.
+ - Fixed thenable assimilation.
+ - Fixed some issues with asap, when it resolves to
+   undefined, or throws an exception.
+
+## 0.3.0 - BACKWARD-INCOMPATIBLE
+
+ - The `post` method has been reverted to its original
+   signature, as provided in Tyler Close's `ref_send` API.
+   That is, `post` accepts two arguments, the second of
+   which is an arbitrary object, but usually invocation
+   arguments as an `Array`.  To provide variadic arguments
+   to `post`, there is a new `invoke` function that posts
+   the variadic arguments to the value given in the first
+   argument.
+ - The `defined` method has been moved from `q` to `q/util`
+   since it gets no use in practice but is still
+   theoretically useful.
+ - The `Promise` constructor has been renamed to
+   `makePromise` to be consistent with the convention that
+   functions that do not require the `new` keyword to be
+   used as constructors have camelCase names.
+ - The `isResolved` function has been renamed to
+   `isFulfilled`.  There is a new `isResolved` function that
+   indicates whether a value is not a promise or, if it is a
+   promise, whether it has been either fulfilled or
+   rejected.  The code has been revised to reflect this
+   nuance in terminology.
+
+## 0.2.10
+
+ - Added `join` to `"q/util"` for variadically joining
+   multiple promises.
+
+## 0.2.9
+
+ - The future-compatible `invoke` method has been added,
+   to replace `post`, since `post` will become backward-
+   incompatible in the next major release.
+ - Exceptions thrown in the callbacks of a `when` call are
+   now emitted to Node's `"uncaughtException"` `process`
+   event in addition to being returned as a rejection reason.
+
+## 0.2.8
+
+ - Exceptions thrown in the callbacks of a `when` call
+   are now consumed, warned, and transformed into
+   rejections of the promise returned by `when`.
+
+## 0.2.7
+
+ - Fixed a minor bug in thenable assimilation, regressed
+   because of the change in the forwarding protocol.
+ - Fixed behavior of "q/util" `deep` method on dates and
+   other primitives. Github issue #11.
+
+## 0.2.6
+
+ - Thenables (objects with a "then" method) are accepted
+   and provided, bringing this implementation of Q
+   into conformance with Promises/A, B, and D.
+ - Added `makePromise`, to replace the `Promise` function
+   eventually.
+ - Rejections are now also duck-typed. A rejection is a
+   promise with a valueOf method that returns a rejection
+   descriptor. A rejection descriptor has a
+   "promiseRejected" property equal to "true" and a
+   "reason" property corresponding to the rejection reason.
+ - Altered the `makePromise` API such that the `fallback`
+   method no longer receives a superfluous `resolved` method
+   after the `operator`.  The fallback method is responsible
+   only for returning a resolution.  This breaks an
+   undocumented API, so third-party API's depending on the
+   previous undocumented behavior may break.
+
+## 0.2.5
+
+ - Changed promises into a duck-type such that multiple
+   instances of the Q module can exchange promise objects.
+   A promise is now defined as "an object that implements the
+   `promiseSend(op, resolved, ...)` method and `valueOf`".
+ - Exceptions in promises are now captured and returned
+   as rejections.
+
+## 0.2.4
+
+ - Fixed bug in `ref` that prevented `del` messages from
+   being received (gozala)
+ - Fixed a conflict with FireFox 4; constructor property
+   is now read-only.
+
+## 0.2.3
+
+ - Added `keys` message to promises and to the promise API.
+
+## 0.2.2
+
+ - Added boilerplate to `q/queue` and `q/util`.
+ - Fixed missing dependency to `q/queue`.
+
+## 0.2.1
+
+ - The `resolve` and `reject` methods of `defer` objects now
+   return the resolution promise for convenience.
+ - Added `q/util`, which provides `step`, `delay`, `shallow`,
+   `deep`, and three reduction orders.
+ - Added `q/queue` module for a promise `Queue`.
+ - Added `q-comm` to the list of compatible libraries.
+ - Deprecated `defined` from `q`, with intent to move it to
+   `q/util`.
+
+## 0.2.0 - BACKWARD INCOMPATIBLE
+
+ - Changed post(ref, name, args) to variadic
+   post(ref, name, ...args). BACKWARD INCOMPATIBLE
+ - Added a def(value) method to annotate an object as being
+   necessarily a local value that cannot be serialized, such
+   that inter-process/worker/vat promise communication
+   libraries will send messages to it, but never send it
+   back.
+ - Added a send(value, op, ...args) method to the public API, for
+   forwarding messages to a value or promise in a future turn.
+
+## 0.1.9
+
+ - Added isRejected() for testing whether a value is a rejected
+   promise.  isResolved() retains the behavior of stating
+   that rejected promises are not resolved.
+
+## 0.1.8
+
+ - Fixed isResolved(null) and isResolved(undefined) [issue #9]
+ - Fixed a problem with the Object.create shim
+
+## 0.1.7
+
+ - shimmed ES5 Object.create in addition to Object.freeze
+   for compatibility on non-ES5 engines (gozala)
+
+## 0.1.6
+
+ - Q.isResolved added
+ - promise.valueOf() now returns the value of resolved
+   and near values
+ - asap retried
+ - promises are frozen when possible
+
+## 0.1.5
+
+ - fixed dependency list for Teleport (gozala)
+ - all unit tests now pass (gozala)
+
+## 0.1.4
+
+ - added support for Teleport as an engine (gozala)
+ - simplified and updated methods for getting internal
+   print and enqueue functions universally (gozala)
+
+## 0.1.3
+
+ - fixed erroneous link to the q module in package.json
+
+## 0.1.2
+
+ - restructured for overlay style package compatibility
+
+## 0.1.0
+
+ - removed asap because it was broken, probably down to the
+   philosophy.
+
+## 0.0.3
+
+ - removed q-util
+ - fixed asap so it returns a value if completed
+
+## 0.0.2
+
+ - added q-util
+
+## 0.0.1
+
+ - initial version

+
+If a function cannot return a value or throw an exception without
+blocking, it can return a promise instead.  A promise is an object
+that represents the return value or the thrown exception that the
+function may eventually provide.  A promise can also be used as a
+proxy for a [remote object][Q-Connection] to overcome latency.
+
+[Q-Connection]: https://github.com/kriskowal/q-connection
+
+On the first pass, promises can mitigate the “[Pyramid of
+Doom][POD]”: the situation where code marches to the right faster
+than it marches forward.
+
+[POD]: http://calculist.org/blog/2011/12/14/why-coroutines-wont-work-on-the-web/
+
+```javascript
+step1(function (value1) {
+    step2(value1, function(value2) {
+        step3(value2, function(value3) {
+            step4(value3, function(value4) {
+                // Do something with value4
+            });
+        });
+    });
+});
+```
+
+With a promise library, you can flatten the pyramid.
+
+```javascript
+Q.fcall(promisedStep1)
+.then(promisedStep2)
+.then(promisedStep3)
+.then(promisedStep4)
+.then(function (value4) {
+    // Do something with value4
+})
+.catch(function (error) {
+    // Handle any error from all above steps
+})
+.done();
+```
+
+With this approach, you also get implicit error propagation, just like `try`,
+`catch`, and `finally`.  An error in `promisedStep1` will flow all the way to
+the `catch` function, where it’s caught and handled.  (Here `promisedStepN` is
+a version of `stepN` that returns a promise.)
+
+The callback approach is called an “inversion of control”.
+A function that accepts a callback instead of a return value
+is saying, “Don’t call me, I’ll call you.”.  Promises
+[un-invert][IOC] the inversion, cleanly separating the input
+arguments from control flow arguments.  This simplifies the
+use and creation of API’s, particularly variadic,
+rest and spread arguments.

+## Getting Started
+
+The Q module can be loaded as:
+
+-   A ``<script>`` tag (creating a ``Q`` global variable): ~2.5 KB minified and
+    gzipped.
+-   A Node.js and CommonJS module, available in [npm](https://npmjs.org/) as
+    the [q](https://npmjs.org/package/q) package
+-   An AMD module
+-   A [component](https://github.com/component/component) as ``microjs/q``
+-   Using [bower](http://bower.io/) as `q#^1.4.1`
+-   Using [NuGet](http://nuget.org/) as [Q](https://nuget.org/packages/q)
+
+Q can exchange promises with jQuery, Dojo, When.js, WinJS, and more.
+
+## Resources
+
+Our [wiki][] contains a number of useful resources, including:
+
+- A method-by-method [Q API reference][reference].
+- A growing [examples gallery][examples], showing how Q can be used to make
+  everything better. From XHR to database access to accessing the Flickr API,
+  Q is there for you.
+- There are many libraries that produce and consume Q promises for everything
+  from file system/database access or RPC to templating. For a list of some of
+  the more popular ones, see [Libraries][].
+- If you want materials that introduce the promise concept generally, and the
+  below tutorial isn't doing it for you, check out our collection of

+
+## Tutorial
+
+Promises have a ``then`` method, which you can use to get the eventual
+return value (fulfillment) or thrown exception (rejection).
+
+```javascript
+promiseMeSomething()
+.then(function (value) {
+}, function (reason) {
+});
+```
+
+If ``promiseMeSomething`` returns a promise that gets fulfilled later
+with a return value, the first function (the fulfillment handler) will be
+called with the value.  However, if the ``promiseMeSomething`` function
+gets rejected later by a thrown exception, the second function (the
+rejection handler) will be called with the exception.
+
+Note that resolution of a promise is always asynchronous: that is, the
+fulfillment or rejection handler will always be called in the next turn of the
+event loop (i.e. `process.nextTick` in Node). This gives you a nice
+guarantee when mentally tracing the flow of your code, namely that
+``then`` will always return before either handler is executed.
+
+In this tutorial, we begin with how to consume and work with promises. We'll
+talk about how to create them, and thus create functions like
+`promiseMeSomething` that return promises, [below](#the-beginning).
+
+
+### Propagation
+
+The ``then`` method returns a promise, which in this example, I’m
+assigning to ``outputPromise``.
+
+```javascript
+var outputPromise = getInputPromise()
+.then(function (input) {
+}, function (reason) {
+});
+```
+
+The ``outputPromise`` variable becomes a new promise for the return
+value of either handler.  Since a function can only either return a
+value or throw an exception, only one handler will ever be called and it
+will be responsible for resolving ``outputPromise``.
+
+-   If you return a value in a handler, ``outputPromise`` will get
+    fulfilled.
+
+-   If you throw an exception in a handler, ``outputPromise`` will get
+    rejected.
+
+-   If you return a **promise** in a handler, ``outputPromise`` will
+    “become” that promise.  Being able to become a new promise is useful
+    for managing delays, combining results, or recovering from errors.
+
+If the ``getInputPromise()`` promise gets rejected and you omit the
+rejection handler, the **error** will go to ``outputPromise``:
+
+```javascript
+var outputPromise = getInputPromise()
+.then(function (value) {
+});
+```
+
+If the input promise gets fulfilled and you omit the fulfillment handler, the
+**value** will go to ``outputPromise``:
+
+```javascript
+var outputPromise = getInputPromise()
+.then(null, function (error) {
+});
+```
+
+Q promises provide a ``fail`` shorthand for ``then`` when you are only
+interested in handling the error:
+
+```javascript
+var outputPromise = getInputPromise()
+.fail(function (error) {
+});
+```
+
+If you are writing JavaScript for modern engines only or using
+CoffeeScript, you may use `catch` instead of `fail`.
+
+Promises also have a ``fin`` function that is like a ``finally`` clause.
+The final handler gets called, with no arguments, when the promise
+returned by ``getInputPromise()`` either returns a value or throws an
+error.  The value returned or error thrown by ``getInputPromise()``
+passes directly to ``outputPromise`` unless the final handler fails, and
+may be delayed if the final handler returns a promise.
+
+```javascript
+var outputPromise = getInputPromise()
+.fin(function () {
+    // close files, database connections, stop servers, conclude tests
+});
+```
+
+-   If the handler returns a value, the value is ignored
+-   If the handler throws an error, the error passes to ``outputPromise``
+-   If the handler returns a promise, ``outputPromise`` gets postponed.  The
+    eventual value or error has the same effect as an immediate return
+    value or thrown error: a value would be ignored, an error would be
+    forwarded.
+
+If you are writing JavaScript for modern engines only or using
+CoffeeScript, you may use `finally` instead of `fin`.
+
+### Chaining
+
+There are two ways to chain promises.  You can chain promises either
+inside or outside handlers.  The next two examples are equivalent.
+
+```javascript
+return getUsername()
+.then(function (username) {
+    return getUser(username)
+    .then(function (user) {
+        // if we get here without an error,
+        // the value returned here
+        // or the exception thrown here
+        // resolves the promise returned
+        // by the first line
+    })
+});
+```
+
+```javascript
+return getUsername()
+.then(function (username) {
+    return getUser(username);
+})
+.then(function (user) {
+    // if we get here without an error,
+    // the value returned here
+    // or the exception thrown here
+    // resolves the promise returned
+    // by the first line
+});
+```
+
+The only difference is nesting.  It’s useful to nest handlers if you
+need to capture multiple input values in your closure.
+
+```javascript
+function authenticate() {
+    return getUsername()
+    .then(function (username) {
+        return getUser(username);
+    })
+    // chained because we will not need the user name in the next event
+    .then(function (user) {
+        return getPassword()
+        // nested because we need both user and password next
+        .then(function (password) {
+            if (user.passwordHash !== hash(password)) {
+                throw new Error("Can't authenticate");
+            }
+        });
+    });
+}
+```
+
+
+### Combination
+
+You can turn an array of promises into a promise for the whole,
+fulfilled array using ``all``.
+
+```javascript
+return Q.all([
+    eventualAdd(2, 2),
+    eventualAdd(10, 20)
+]);
+```
+
+If you have a promise for an array, you can use ``spread`` as a
+replacement for ``then``.  The ``spread`` function “spreads” the
+values over the arguments of the fulfillment handler.  The rejection handler
+will get called at the first sign of failure.  That is, whichever of
+the received promises fails first gets handled by the rejection handler.
+
+```javascript
+function eventualAdd(a, b) {
+    return Q.spread([a, b], function (a, b) {
+        return a + b;
+    })
+}
+```
+
+But ``spread`` calls ``all`` initially, so you can skip it in chains.
+
+```javascript
+return getUsername()
+.then(function (username) {
+    return [username, getUser(username)];
+})
+.spread(function (username, user) {
+});
+```
+
+The ``all`` function returns a promise for an array of values.  When this
+promise is fulfilled, the array contains the fulfillment values of the original
+promises, in the same order as those promises.  If one of the given promises
+is rejected, the returned promise is immediately rejected, not waiting for the
+rest of the batch.  If you want to wait for all of the promises to either be
+fulfilled or rejected, you can use ``allSettled``.
+
+```javascript
+Q.allSettled(promises)
+.then(function (results) {
+    results.forEach(function (result) {
+        if (result.state === "fulfilled") {
+            var value = result.value;
+        } else {
+            var reason = result.reason;
+        }
+    });
+});
+```
+
+The ``any`` function accepts an array of promises and returns a promise that is
+fulfilled by the first given promise to be fulfilled, or rejected if all of the
+given promises are rejected.
+
+```javascript
+Q.any(promises)
+.then(function (first) {
+    // Any of the promises was fulfilled.
+}, function (error) {
+    // All of the promises were rejected.
+});
+```
+
+### Sequences
+
+If you have a number of promise-producing functions that need
+to be run sequentially, you can of course do so manually:
+
+```javascript
+return foo(initialVal).then(bar).then(baz).then(qux);
+```
+
+However, if you want to run a dynamically constructed sequence of
+functions, you'll want something like this:
+
+```javascript
+var funcs = [foo, bar, baz, qux];
+
+var result = Q(initialVal);
+funcs.forEach(function (f) {
+    result = result.then(f);
+});
+return result;
+```
+
+You can make this slightly more compact using `reduce`:
+
+```javascript
+return funcs.reduce(function (soFar, f) {
+    return soFar.then(f);
+}, Q(initialVal));
+```
+
+Or, you could use the ultra-compact version:
+
+```javascript
+return funcs.reduce(Q.when, Q(initialVal));
+```
+
+### Handling Errors
+
+One sometimes-unintuitive aspect of promises is that if you throw an
+exception in the fulfillment handler, it will not be caught by the error
+handler.
+
+```javascript
+return foo()
+.then(function (value) {
+    throw new Error("Can't bar.");
+}, function (error) {
+    // We only get here if "foo" fails
+});
+```
+
+To see why this is, consider the parallel between promises and
+``try``/``catch``. We are ``try``-ing to execute ``foo()``: the error
+handler represents a ``catch`` for ``foo()``, while the fulfillment handler
+represents code that happens *after* the ``try``/``catch`` block.
+That code then needs its own ``try``/``catch`` block.
+
+In terms of promises, this means chaining your rejection handler:
+
+```javascript
+return foo()
+.then(function (value) {
+    throw new Error("Can't bar.");
+})
+.fail(function (error) {
+    // We get here with either foo's error or bar's error
+});
+```
+
+### Progress Notification
+
+It's possible for promises to report their progress, e.g. for tasks that take a
+long time like a file upload. Not all promises will implement progress
+notifications, but for those that do, you can consume the progress values using
+a third parameter to ``then``:
+
+```javascript
+return uploadFile()
+.then(function () {
+    // Success uploading the file
+}, function (err) {
+    // There was an error, and we get the reason for error
+}, function (progress) {
+    // We get notified of the upload's progress as it is executed
+});
+```
+
+Like `fail`, Q also provides a shorthand for progress callbacks
+called `progress`:
+
+```javascript
+return uploadFile().progress(function (progress) {
+    // We get notified of the upload's progress
+});
+```
+
+### The End
+
+When you get to the end of a chain of promises, you should either
+return the last promise or end the chain.  Since handlers catch
+errors, it’s an unfortunate pattern that the exceptions can go
+unobserved.
+
+So, either return it,
+
+```javascript
+return foo()
+.then(function () {
+    return "bar";
+});
+```
+
+Or, end it.
+
+```javascript
+foo()
+.then(function () {
+    return "bar";
+})
+.done();
+```
+
+Ending a promise chain makes sure that, if an error doesn’t get
+handled before the end, it will get rethrown and reported.
+
+This is a stopgap. We are exploring ways to make unhandled errors
+visible without any explicit handling.
+
+
+### The Beginning
+
+Everything above assumes you get a promise from somewhere else.  This
+is the common case.  Every once in a while, you will need to create a
+promise from scratch.
+
+#### Using ``Q.fcall``
+
+You can create a promise from a value using ``Q.fcall``.  This returns a
+promise for 10.
+
+```javascript
+return Q.fcall(function () {
+    return 10;
+});
+```
+
+You can also use ``fcall`` to get a promise for an exception.
+
+```javascript
+return Q.fcall(function () {
+    throw new Error("Can't do it");
+});
+```
+
+As the name implies, ``fcall`` can call functions, or even promised
+functions.  This uses the ``eventualAdd`` function above to add two
+numbers.
+
+```javascript
+return Q.fcall(eventualAdd, 2, 2);
+```
+
+
+#### Using Deferreds
+
+If you have to interface with asynchronous functions that are callback-based
+instead of promise-based, Q provides a few shortcuts (like ``Q.nfcall`` and
+friends). But much of the time, the solution will be to use *deferreds*.
+
+```javascript
+var deferred = Q.defer();
+FS.readFile("foo.txt", "utf-8", function (error, text) {
+    if (error) {
+        deferred.reject(new Error(error));
+    } else {
+        deferred.resolve(text);
+    }
+});
+return deferred.promise;
+```
+
+Note that a deferred can be resolved with a value or a promise.  The
+``reject`` function is a shorthand for resolving with a rejected
+promise.
+
+```javascript
+// this:
+deferred.reject(new Error("Can't do it"));
+
+// is shorthand for:
+var rejection = Q.fcall(function () {
+    throw new Error("Can't do it");
+});
+deferred.resolve(rejection);
+```
+
+This is a simplified implementation of ``Q.delay``.
+
+```javascript
+function delay(ms) {
+    var deferred = Q.defer();
+    setTimeout(deferred.resolve, ms);
+    return deferred.promise;
+}
+```
+
+This is a simplified implementation of ``Q.timeout``
+
+```javascript
+function timeout(promise, ms) {
+    var deferred = Q.defer();
+    Q.when(promise, deferred.resolve);
+    delay(ms).then(function () {
+        deferred.reject(new Error("Timed out"));
+    });
+    return deferred.promise;
+}
+```
+
+Finally, you can send a progress notification to the promise with
+``deferred.notify``.
+
+For illustration, this is a wrapper for XML HTTP requests in the browser. Note
+that a more [thorough][XHR] implementation would be in order in practice.
+
+[XHR]: https://github.com/montagejs/mr/blob/71e8df99bb4f0584985accd6f2801ef3015b9763/browser.js#L29-L73
+
+```javascript
+function requestOkText(url) {
+    var request = new XMLHttpRequest();
+    var deferred = Q.defer();
+
+    request.open("GET", url, true);
+    request.onload = onload;
+    request.onerror = onerror;
+    request.onprogress = onprogress;
+    request.send();
+
+    function onload() {
+        if (request.status === 200) {
+            deferred.resolve(request.responseText);
+        } else {
+            deferred.reject(new Error("Status code was " + request.status));
+        }
+    }
+
+    function onerror() {
+        deferred.reject(new Error("Can't XHR " + JSON.stringify(url)));
+    }
+
+    function onprogress(event) {
+        deferred.notify(event.loaded / event.total);
+    }
+
+    return deferred.promise;
+}
+```
+
+Below is an example of how to use this ``requestOkText`` function:
+
+```javascript
+requestOkText("http://localhost:3000")
+.then(function (responseText) {
+    // If the HTTP response returns 200 OK, log the response text.
+    console.log(responseText);
+}, function (error) {
+    // If there's an error or a non-200 status code, log the error.
+    console.error(error);
+}, function (progress) {
+    // Log the progress as it comes in.
+    console.log("Request progress: " + Math.round(progress * 100) + "%");
+});
+```
+
+#### Using `Q.Promise`
+
+This is an alternative promise-creation API that has the same power as
+the deferred concept, but without introducing another conceptual entity.
+
+Rewriting the `requestOkText` example above using `Q.Promise`:
+
+```javascript
+function requestOkText(url) {
+    return Q.Promise(function(resolve, reject, notify) {
+        var request = new XMLHttpRequest();
+
+        request.open("GET", url, true);
+        request.onload = onload;
+        request.onerror = onerror;
+        request.onprogress = onprogress;
+        request.send();
+
+        function onload() {
+            if (request.status === 200) {
+                resolve(request.responseText);
+            } else {
+                reject(new Error("Status code was " + request.status));
+            }
+        }
+
+        function onerror() {
+            reject(new Error("Can't XHR " + JSON.stringify(url)));
+        }
+
+        function onprogress(event) {
+            notify(event.loaded / event.total);
+        }
+    });
+}
+```
+
+If `requestOkText` were to throw an exception, the returned promise would be
+rejected with that thrown exception as the rejection reason.
+
+### The Middle
+
+If you are using a function that may return a promise, but just might
+return a value if it doesn’t need to defer, you can use the “static”
+methods of the Q library.
+
+The ``when`` function is the static equivalent for ``then``.
+
+```javascript
+return Q.when(valueOrPromise, function (value) {
+}, function (error) {
+});
+```
+
+All of the other methods on a promise have static analogs with the
+same name.
+
+The following are equivalent:
+
+```javascript
+return Q.all([a, b]);
+```
+
+```javascript
+return Q.fcall(function () {
+    return [a, b];
+})
+.all();
+```
+
+When working with promises provided by other libraries, you should
+convert it to a Q promise.  Not all promise libraries make the same
+guarantees as Q and certainly don’t provide all of the same methods.
+Most libraries only provide a partially functional ``then`` method.
+This thankfully is all we need to turn them into vibrant Q promises.
+
+```javascript
+return Q($.ajax(...))
+.then(function () {
+});
+```
+
+If there is any chance that the promise you receive is not a Q promise
+as provided by your library, you should wrap it using a Q function.
+You can even use ``Q.invoke`` as a shorthand.
+
+```javascript
+return Q.invoke($, 'ajax', ...)
+.then(function () {
+});
+```
+
+
+### Over the Wire
+
+A promise can serve as a proxy for another object, even a remote
+object.  There are methods that allow you to optimistically manipulate
+properties or call functions.  All of these interactions return
+promises, so they can be chained.
+
+```
+direct manipulation         using a promise as a proxy
+--------------------------  -------------------------------
+value.foo                   promise.get("foo")
+value.foo = value           promise.put("foo", value)
+delete value.foo            promise.del("foo")
+value.foo(...args)          promise.post("foo", [args])
+value.foo(...args)          promise.invoke("foo", ...args)
+value(...args)              promise.fapply([args])
+value(...args)              promise.fcall(...args)
+```
+
+If the promise is a proxy for a remote object, you can shave
+round-trips by using these functions instead of ``then``.  To take
+advantage of promises for remote objects, check out [Q-Connection][].
+
+[Q-Connection]: https://github.com/kriskowal/q-connection
+
+Even in the case of non-remote objects, these methods can be used as
+shorthand for particularly-simple fulfillment handlers. For example, you
+can replace
+
+```javascript
+return Q.fcall(function () {
+    return [{ foo: "bar" }, { foo: "baz" }];
+})
+.then(function (value) {
+    return value[0].foo;
+});
+```
+
+with
+
+```javascript
+return Q.fcall(function () {
+    return [{ foo: "bar" }, { foo: "baz" }];
+})
+.get(0)
+.get("foo");
+```
+
+
+### Adapting Node
+
+If you're working with functions that make use of the Node.js callback pattern,
+where callbacks are in the form of `function(err, result)`, Q provides a few
+useful utility functions for converting between them. The most straightforward
+are probably `Q.nfcall` and `Q.nfapply` ("Node function call/apply") for calling
+Node.js-style functions and getting back a promise:
+
+```javascript
+return Q.nfcall(FS.readFile, "foo.txt", "utf-8");
+return Q.nfapply(FS.readFile, ["foo.txt", "utf-8"]);
+```
+
+If you are working with methods, instead of simple functions, you can easily
+run in to the usual problems where passing a method to another function—like
+`Q.nfcall`—"un-binds" the method from its owner. To avoid this, you can either
+use `Function.prototype.bind` or some nice shortcut methods we provide:
+
+```javascript
+return Q.ninvoke(redisClient, "get", "user:1:id");
+return Q.npost(redisClient, "get", ["user:1:id"]);
+```
+
+You can also create reusable wrappers with `Q.denodeify` or `Q.nbind`:
+
+```javascript
+var readFile = Q.denodeify(FS.readFile);
+return readFile("foo.txt", "utf-8");
+
+var redisClientGet = Q.nbind(redisClient.get, redisClient);
+return redisClientGet("user:1:id");
+```
+
+Finally, if you're working with raw deferred objects, there is a
+`makeNodeResolver` method on deferreds that can be handy:
+
+```javascript
+var deferred = Q.defer();
+FS.readFile("foo.txt", "utf-8", deferred.makeNodeResolver());
+return deferred.promise;
+```
+
+### Long Stack Traces
+
+Q comes with optional support for “long stack traces,” wherein the `stack`
+property of `Error` rejection reasons is rewritten to be traced along
+asynchronous jumps instead of stopping at the most recent one. As an example:
+
+```js
+function theDepthsOfMyProgram() {
+  Q.delay(100).done(function explode() {
+    throw new Error("boo!");
+  });
+}
+
+theDepthsOfMyProgram();
+```
+
+usually would give a rather unhelpful stack trace looking something like
+
+```
+Error: boo!
+    at explode (/path/to/test.js:3:11)
+    at _fulfilled (/path/to/test.js:q:54)
+    at resolvedValue.promiseDispatch.done (/path/to/q.js:823:30)
+    at makePromise.promise.promiseDispatch (/path/to/q.js:496:13)
+    at pending (/path/to/q.js:397:39)
+    at process.startup.processNextTick.process._tickCallback (node.js:244:9)
+```
+
+But, if you turn this feature on by setting
+
+```js
+Q.longStackSupport = true;
+```
+
+then the above code gives a nice stack trace to the tune of
+
+```
+Error: boo!
+    at explode (/path/to/test.js:3:11)
+From previous event:
+    at theDepthsOfMyProgram (/path/to/test.js:2:16)
+    at Object.<anonymous> (/path/to/test.js:7:1)
+```
+
+Note how you can see the function that triggered the async operation in the
+stack trace! This is very helpful for debugging, as otherwise you end up getting
+only the first line, plus a bunch of Q internals, with no sign of where the
+operation started.
+
+In node.js, this feature can also be enabled through the Q_DEBUG environment
+variable:
+
+```
+Q_DEBUG=1 node server.js
+```
+
+This will enable long stack support in every instance of Q.
+
+This feature does come with somewhat-serious performance and memory overhead,
+however. If you're working with lots of promises, or trying to scale a server
+to many users, you should probably keep it off. But in development, go for it!
