## 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 Millers 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][].

(*) Use of ``thisp`` is discouraged. For calling methods, use ``post`` or
``invoke``.
### 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 79 (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
@gozalas 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
