### 3.7.4
|
|
|
|
* Add `when/keys settle`, for settling a hash of promises.
|
|

|
|
* Several community-contributed doc fixes. Thanks!
|
|
|
|
### 3.7.2
|
|
|
|
* Republish 3.7.1 npm package: for some reason, `npm publish` did not include the file `poll.js` when publishing 3.7.1
|
|
* No functional changes
|
|
|
|
### 3.7.1
|
|
|
|
* Fix `when.settle` unhandled rejection reporting case.
|
|
|
|
### 3.7.0

|
|
### 3.6.3
|
|
|
|
* Fix regression in `when/callbacks` introduced in 3.6.1
|
|
|
|
### 3.6.2
|
|
|
|
* Work around [v8 optimizing compiler bug](https://code.google.com/p/v8/issues/detail?id=3692) with some *truly amazing* help from community members. Thank you [@anodynos](https://github.com/anodynos), [@jefflage](https://github.com/jefflage), [@pbarnes](https://github.com/pbarnes), [@spion](https://github.com/spion), [@tsouza](https://github.com/tsouza).
|
|
* Fix regressions in `when.filter` and `when.reduce` (which also affected `when/sequence`).
|
|
|
|
### 3.6.1
|
|
|
|
* Significant improvements to `when.try`, and `when.lift`.
|
|
* Additional improvements to array functions: `when.reduce`, `when.any`, and `when.some`.
|
|
* Improved handling of early bail-out cases in `when.all`, `when.map`, and `when.any`.
|
|
|
|
### 3.6.0
|
|
|
|
* Significant performance improvements:
|
|
* 10x or more for `when.map`, especially for large arrays
|
|
* ~2x for `when.reduce` and `promise.fold`
|
|
* ~1.5-2x for generators using `when/generator` `lift`, `call`, and/or `apply`.
|
|
* Memory use reductions for `when.reduce` and `promise.fold`.
|
|
|
|
### 3.5.2
|
|
|
|
* Prevent minifiers from clobbering unhandled rejection reporting if they remove `console.*` calls. Unhandled rejections will be reported even when using Uglify `drop_console`.
|
|
* `when/function.apply` now handles passing an Arguments object directly, e.g. `fn.apply(f, arguments);`. Use with care: v8 will deoptimize any function where you pass `arguments` to another function.
|
|
|
|
### 3.5.1
|
|
|
|
* `when.race` & `Promise.race` now reject with a `TypeError` if you pass something that is not iterable.
|
|
* Improve scheduler compatibility with MutationObserver shims
|
|
* Simplify checks for vert.x environment

* Improve `when.race` & `Promise.race` performance.
|
|
* Internal changes to start paving the way toward 4.0.0.
|
|
* Deprecate `when.iterate` and `when.unfold`. Use [cujoJS/most](https://github.com/cujojs/most) for streaming asynchronous values.
|
|
* Deprecate progress events. See [the docs for more information](docs/api.md#progress-events-are-deprecated) and [tips on refactoring](docs/api.md#refactoring-progress) code that uses promise progress.
|
|
|
|
### 3.4.6
|
|
|
|
* Fix webpack compatibility by excluding `vertx` from browser bundles
|
|
|
|
### 3.4.5
|
|
|
|
* Fixes for edge cases for unhandled rejection reporting
|
|
|
|
### 3.4.4
|
|
|
|
* Workaround for node 0.10.30 setTimeout bug. See [this issue](https://github.com/joyent/node/issues/8167)
|
|
|
|
### 3.4.3
|
|
|
|
* Improve error handling for [predicate catch](docs/api.md#promisecatch)
|
|
* Simplify internals and reduce code size
|
|
|
|
### 3.4.2
|
|
|
|
* Fix for rare false negative in [unhandled rejection reporting](docs/api.md#debugging-promises).
|
|
|
|
### 3.4.1
|
|
|
|
* Fix for `promise.finally` not waiting on returned promises.
|
|
|
|
### 3.4.0
|
|
|
|
* New [`when.filter`](docs/api.md#whenfilter) for filtering arrays of promises.
|
|
* [`when.map`](docs/api.md#whenmap) and [`when.filter`](docs/api.md#whenfilter) now provide the array index as the second param to their mapping and filtering functions.
|
|
* [`when/keys.map`](docs/api.md#whenkeys-map) now provides the associated key to its mapping function.
|
|
* Smaller ES6 shim.
|
|
|
|
### 3.3.1
|
|
|
|
* Fix argument ordering bug in `when/node` introduced in 3.3.0.
|
|
|
|
### 3.3.0
|
|
|
|
* Promote [`when.race`](docs/api.md#whenrace) to public API.
|
|
* `when.any` and `when.some` now reject with a `RangeError` if the race is obviously unwinnable, for example: `when.some([1,2,3], 4)`. See the [`when.any`](docs/api.md#whenany) and [`when.some`](docs/api.md#whensome) docs for more info.
|
|
|
|
### 3.2.3
|
|
|
|
* Updated [debugging docs](docs/api.md#debugging-promises)
|
|
* Report when previously unhandled rejections become handled, with an ID to correlate the two messages.
|
|
* Improve unhandled rejection reporting for cases where multiple different promise implementations interleave.
|
|
|
|
### 3.2.2
|
|
|
|
* More mem and perf improvements
|
|
* Improvements to unhandled rejection reporting
|
|
|
|
### 3.2.1
|
|
|
|
* Minor mem and perf tweaks for `when.all`
|
|
* Defend against `JSON.stringify` exceptions when formatting unhandled rejection output.
|
|
|
|
### 3.2.0
|
|
|
|
* Potentially unhandled rejections are now logged to `console.error` by default, even without using `done` or `when/monitor/console`. As before, enabling `when/monitor/console` still adds long async stack traces, and using `done` still makes errors fatal. See [Debugging Promises](docs/api.md#debugging-promises) for more info.
|
|
* [`promise.timeout`](docs/api.md#promisetimeout) now rejects with a [`TimeoutError`](docs/api.md#timeouterror) by default (unless you specify a custom reason) for better pattern matching with [`promise.catch`](docs/api.md#promisecatch).
|
|
* Performance improvements across the board, especially to `when.all` (and `Promise.all` in the [ES6-shim](docs/es6-promise-shim.md)) and `node.lift`: lifted functions and lift*ing* are faster now.
|
|
* New [`promise.fold`](docs/api.md#promisefold) for combining two promises to generate a new promise.
|
|
* Deprecated:
|
|
* Using `when/node.lift`, `when/function.lift`, and `when/callbacks.lift` to provide partial arguments
|
|
* `promise.then`'s 3rd argument, and `when()`'s 4th argument. Use the dedicated [`promise.progress`](docs/api.md#promiseprogress) API to listen to promise progress events.
|
|
* `when.some`. See https://github.com/cujojs/when/issues/288
|
|
* `when/callbacks.promisify` See https://github.com/cujojs/when/issues/318
|
|
|
|
### 3.1.0
|
|
|
|
* Added [optional `reason` param to `promise.timeout`](docs/api.md#promisetimeout) to specify your own timeout value.
|
|
* Another significant speed bump for `when.all` (and es6-shim `Promise.all`)
|
|
* More `when/monitor/console` long stack trace improvements. Traces can track nested async functions [even if you forget to return a promise](docs/api.md#whenmonitorconsole).
|
|
* Clean up bower and npm installs by ignoring more markdown files
|
|
|
|
### 3.0.1
|
|
|
|
* [API doc](docs/api.md) updates and fixes
|
|
* Improvements to unhandled rejection long stack trace filtering
|
|
* Internal performance improvements
|
|
|
|
### 3.0.0
|
|
|
|
* New internal architecture with significant performance improvements and memory efficiency
|
|
* New APIs
|
|
* [`when.try`](docs/api.md#whentry), [`when.lift`](docs/api.md#whenlift), [`when.reduceRight`](docs/api.md#whenreduceRight), [`when.iterate`](docs/api.md#wheniterate), [`when.unfold`](docs/api.md#whenunfold), [`when.race`](docs/api.md#whenrace)
|
|
* [`promise.with`](docs/api.md#promisewith), [`promise.else`](docs/api.md#promiseelse), [`promise.delay`](docs/api.md#promisedelay), [`promise.timeout`](docs/api.md#promisetimeout), [`promise.progress`](docs/api.md#promiseprogress)
|
|
* New liftAll variants for lifting all of an object's functions in one shot, eg. `var promisedFs = node.liftAll(require('fs'))`
|
|
* [`fn.liftAll`](docs/api.md#fnliftall), [`node.liftAll`](docs/api.md#nodeliftall), [`callbacks.liftAll`](docs/api.md#callbacksliftall)
|
|
* `when.Promise` public, inheritance-friendly, Promise constructor
|
|
* New [ES6 Promise shim](docs/es6-promise-shim.md)
|
|
* Check out the [tips for upgrading to 3.0 from 2.x](docs/api.md#upgrading-to-30-from-2x)
|
|
|
|
### 2.8.0
|
|
|
|
* Experimental [ES6 generator support](docs/api.md#es6-generators) via new `when/generator` module, with `lift`, `call`, `apply`.
|
|
|
|
### 2.7.1
|
|
|
|
* Internal changes to reduce overall memory usage, along with minor performance improvements.
|
|
|
|
### 2.7.0
|
|
|
|
* Added [`promise.catch`](docs/api.md#catch) and [`promise.finally`](docs/api.md#finally) as synonyms for `promise.otherwise` and `promise.ensure`. (#212)
|
|
* New [browserify build](../README.md#legacy-environments-via-browserify) for those using globals. (#209)
|
|
* Added [ender](http://ender.jit.su) support to `package.json`. (#223)
|
|
* Fix compatibility with [PhantomJS](http://phantomjs.org)'s CommonJS module support. (#226)
|
|
* Fix [Sauce Labs](https://saucelabs.com) tests for pull requests. (#216)
|
|
* Added `bower.json` `ignore` to trim files installed via bower. (#193)
|
|
|
|
### 2.6.0
|
|
|
|
* New [`promise.done`](docs/api.md#done) allows consuming the ultimate value at the end of a promise chain while ensuring that any errors are thrown to the host environment so you get loud stack traces.
|
|
* `when/node/function` [`bindCallback`](docs/api.md#nodefn-bindcallback) and [`liftCallback`](docs/api.md#nodefn-liftcallback) now behave more like standard node-style APIs in that they allow exceptions to propagate to the host environment for loud stack traces.
|
|
|
|
### 2.5.1
|
|
|
|
* `ensure` now ignores non-functions, [like `then` does](http://promisesaplus.com/#point-25), for consistency. (#207)
|
|
|
|
### 2.5.0
|
|
|
|
* [Promises/A+ 1.1](http://promisesaplus.com) compliant. Passes version 2.0.0 of the [Promises/A+ test suite](https://github.com/promises-aplus/promises-tests).
|
|
|
|
### 2.4.1
|
|
|
|
* New `MutationObserver` scheduler further reduces "time-to-first-handler" in modern browsers. (#198)
|
|
* Also, this works around a horrible IE10 bug (desktop and mobile) that renders `setImmediate`, `MessageChannel`, and `postMessage` unusable as fast task schedulers. Many thanks to @plaa and @calvinmetcalf for their help in discovering the problem and working out a solution. (#197)
|
|
|
|
### 2.4.0
|
|
|
|
* Experimental support for [vert.x 2.x](http://vertx.io). Should now run in vert.x >= 1.1.0.
|
|
* New `when.isPromiseLike` as the more accurately-named synonym for `when.isPromise`.
|
|
* **DEPRECATED**: `when.isPromise`. It can only tell you that something is "promise-like" (aka "thenable") anyway. Use the new, more accurately-named `when.isPromiseLike` instead.
|
|
* Fix for promise monitor reporting extra unhandled rejections for `when.all` and `when.map`.
|
|
|
|
### 2.3.0
|
|
|
|
* New [`promise.tap`](docs/api.md#tap) for adding side effects to a promise chain.
|
|
* New `MessageChannel` scheduler reduces "time-to-first" handler, in environments that support it.
|
|
* Performance optimizations for promise resolution.
|
|
* Internal architecture improvements to pave the way for when.js 3.0.0.
|
|
|
|
### 2.2.1
|
|
|
|
* Fix for `when.defer().reject()` bypassing the unhandled rejection monitor. (#166)
|
|
* Fix for `when/function`, `when/callbacks`, and `when/node/function` not preserving `thisArg`. (#162)
|
|
* Doc clarifications for [`promise.yield`](docs/api.md#yield). (#164)
|
|
|
|
### 2.2.0
|
|
|
|
* New experimental [promise monitoring and debugging](docs.md#debugging-promises) via `when/monitor/console`.
|
|
* New [`when.promise(resolver)`](docs/api.md#whenpromise) promise creation API. A lighter alternative to the heavier `when.defer()`
|
|
* New `bindCallback` and `liftCallback` in `when/node/function` for more integration options with node-style callbacks.
|
|
|
|
### 2.1.1
|
|
|
|
* Quote internal usages of `promise.yield` to workaround .NET minifier tools that don't yet understand ES5 identifier-as-property rules. See [#157](https://github.com/cujojs/when/issues/157)
|
|
|
|
### 2.1.0
|
|
|
|
* New [`when.settle`](docs/api.md#whensettle) that settles an array of promises, regardless of whether the fulfill or reject.
|
|
* New [`when/guard`](docs/api.md#whenguard) generalized concurrency guarding and limiting
|
|
* New [`promise.inspect`](docs/api.md#inspect) for synchronously getting a snapshot of a promise's state at a particular instant.
|
|
* Significant performance improvements when resolving promises with non-primitives (Arrays, Objects, etc.)
|
|
* Experimental [vert.x](http://vertx.io) support
|
|
* **DEPRECATED**: `onFulfilled`, `onRejected`, `onProgress` handler arguments to `when.all`, `when.any`, `when.some`. Use the returned promise's `then()` (or `otherwise()`, `ensure()`, etc) to register handlers instead.
|
|
* For example, do this: `when.all(array).then(onFulfilled, onRejected)` instead of this: `when.all(array, onFulfilled, onRejected)`. The functionality is equivalent.
|
|
|
|
### 2.0.1
|
|
|
|
* Account for the fact that Mocha creates a global named `process`. Thanks [Narsul](https://github.com/cujojs/when/pull/136)
|
|
|
|
### 2.0.0
|
|
|
|
* Fully asynchronous resolutions.
|
|
* [Promises/A+](http://promises-aplus.github.com/promises-spec) compliance.
|
|
* New [`when/keys`](docs/api.md#object-keys) module with `all()` and `map()` for object keys/values.
|
|
* New [`promise.ensure`](docs/api.md#ensure) as a better, and safer, replacement for `promise.always`. [See discussion](https://github.com/cujojs/when/issues/103) as to why `promise.always` is mistake-prone.
|
|
* **DEPRECATED:** `promise.always`
|
|
* `lift()` is now the preferred name for what was `bind()` in [when/function](docs/api.md#synchronous-functions), [when/node/function](docs/api.md#node-style-asynchronous-functions), and [when/callbacks](docs/api.md#asynchronous-functions).
|
|
* **DEPRECATED:** `bind()` in `when/function`, `when/node/function`, and `when/callbacks`. Use `lift()` instead.
|
|
|
|
### 1.8.1
|
|
|
|
* Last 1.x.x release before 2.0.0 barring critical fixes.
|
|
* To prepare for 2.0.0, [test your code against the dev-200 branch](https://github.com/cujojs/when/tree/dev-200). It is fully API compatible, but has fully asynchronous resolutions.
|
|
* Performance improvements for [when/function](docs/api.md#synchronous-functions).
|
|
* [Documentation](docs/api.md) updates and fixes. Thanks, [@unscriptable](https://github.com/unscriptable)!
|
|
* **DEPRECATED:** `deferred.progress` and `deferred.resolver.progress`. Use [`deferred.notify`](docs/api.md#progress-events) and [`deferred.resolver.notify`](docs/api.md#progress-events) instead.
|
|
* **DEPRECATED:** [`when.chain`](docs/api.md#whenchain). Use [`resolver.resolve(promise)`](docs/api.md#resolver) or `resolver.resolve(promise.yield)` ([see `promise.yield`](docs/api.md#yield)) instead.
|
|
* **DEPRECATED:** `when/timed` module. Use [`when/delay`](docs/api.md#whendelay) and [`when/timeout`](docs/api.md#whentimeout) modules instead.
|
|
|
|
### 1.8.0
|
|
|
|
* New [when/function](docs/api.md#synchronous-functions), [when/node/function](docs/api.md#node-style-asynchronous-functions), and [when/callbacks](docs/api.md#asynchronous-functions) with functional programming goodness, and adapters for turning callback-based APIs into promise-based APIs. Kudos [@riccieri](https://github.com/riccieri)!
|
|
* New [when/unfold](docs/api.md#whenunfold), and [when/unfold/list](docs/api.md#whenunfoldlist) promise-aware anamorphic unfolds that can be used to generate and/or process unbounded lists.
|
|
* New [when/poll](docs/api.md#whenpoll) promise-based periodic polling and task execution. Kudos [@scothis](https://github.com/scothis)!
|
|
|
|
### 1.7.1
|
|
|
|
* Removed leftover internal usages of `deferred.then`.
|
|
* [when/debug](https://github.com/cujojs/when/wiki/when-debug) allows configuring the set of "fatal" error types that will be rethrown to the host env.
|
|
|
|
### 1.7.0
|
|
|
|
* **DEPRECATED:** `deferred.then` [is deprecated](docs/api.md#deferred) and will be removed in an upcoming release. Use `deferred.promise.then` instead.
|
|
* [promise.yield](docs/api.md#yield)(promiseOrValue) convenience API for substituting a new value into a promise chain.
|
|
* [promise.spread](docs/api.md#spread)(variadicFunction) convenience API for spreading an array onto a fulfill handler that accepts variadic arguments. [Mmmm, buttery](http://s.shld.net/is/image/Sears/033W048977110001_20100422100331516?hei=1600&wid=1600&op_sharpen=1&resMode=sharp&op_usm=0.9,0.5,0,0)
|
|
* Doc improvements:
|
|
* [when()](docs/api.md#when) and [promise.then()](docs/api.md#main-promise-api) have more info about callbacks and chaining behavior.
|
|
* More info and clarifications about the roles of [Deferred](docs/api.md#deferred) and [Resolver](docs/api.md#resolver)
|
|
* Several minor clarifications for various APIs
|
|
* Internal improvements to assimilation and interoperability with other promise implementations.
|
|
|
|
### 1.6.1
|
|
|
|
* Fix for accidental coercion of non-promises. See [#62](https://github.com/cujojs/when/issues/60).
|
|
|
|
### 1.6.0
|
|
|
|
* New [when.join](docs/api.md#whenjoin) - Joins 2 or more promises together into a single promise.
|
|
* [when.some](docs/api.md#whensome) and [when.any](docs/api.md#whenany) now act like competitive races, and have generally more useful behavior. [Read the discussion in #60](https://github.com/cujojs/when/issues/60).
|
|
* *Experimental* progress event propagation. Progress events will propagate through promise chains. [Read the details here](docs/api.md#progress-events).
|
|
* *Temporarily* removed calls to `Object.freeze`. Promises are no longer frozen due to a horrendous v8 performance penalty. [Read discussion here](https://groups.google.com/d/topic/cujojs/w_olYqorbsY/discussion).
|
|
* **IMPORTANT:** Continue to treat promises as if they are frozen, since `freeze()` will be reintroduced once v8 performance improves.
|
|
* [when/debug](https://github.com/cujojs/when/wiki/when-debug) now allows setting global a debugging callback for rejected promises.
|
|
|
|
### 1.5.2
|
|
|
|
* Integrate @domenic's [Promises/A Test Suite](https://github.com/domenic/promise-tests). Runs via `npm test`.
|
|
* No functional change
|
|
|
|
### 1.5.1
|
|
|
|
* Performance optimization for [when.defer](docs/api.md#whendefer), up to 1.5x in some cases.
|
|
* [when/debug](docs/api.md#whendebug) can now log exceptions and rejections in deeper promise chains, in some cases, even when the promises involved aren't when.js promises.
|
|
|
|
### 1.5.0
|
|
|
|
* New task execution and concurrency management: [when/sequence](docs/api.md#whensequence), [when/pipeline](docs/api.md#whenpipeline), and [when/parallel](docs/api.md#whenparallel).
|
|
* Performance optimizations for [when.all](docs/api.md#whenall) and [when.map](docs/api.md#whenmap), up to 2x in some cases.
|
|
* Options for disabling [paranoid mode](docs/api.md#paranoid-mode) that provides a significant performance gain in v8 (e.g. Node and Chrome). See this [v8 performance problem with Object.freeze](http://stackoverflow.com/questions/8435080/any-performance-benefit-to-locking-down-javascript-objects) for more info.
|
|
* **Important:** `deferred` and `deferred.resolver` no longer throw when resolved/rejected multiple times. They will return silently as if the they had succeeded. This prevents parties to whom *only* the `resolver` has been given from using `try/catch` to determine the state of the associated promise.
|
|
* For debugging, you can use the [when/debug](https://github.com/cujojs/when/wiki/when-debug) module, which will still throw when a deferred is resolved/rejected multiple times.
|
|
|
|
### 1.4.4
|
|
|
|
* Change UMD boilerplate to check for `exports` to avoid a problem with QUnit. See [#54](https://github.com/cujojs/when/issues/54) for more info.
|
|
|
|
### 1.4.3
|
|
|
|
* Fix for infinite promise coercion between when.js and Q (See [#50](https://github.com/cujojs/when/issues/50)). Thanks [@kriskowal](https://github.com/kriskowal) and [@domenic](https://github.com/domenic)
|
|
|
|
### 1.4.2
|
|
|
|
* Fix for IE8 infinite recursion (See [#49](https://github.com/cujojs/when/issues/49))
|
|
|
|
### 1.4.1
|
|
|
|
* Code and unit test cleanup and streamlining--no functional changes.
|
|
|
|
### 1.4.0
|
|
|
|
* Create a resolved promise: `when.resolve(value)` creates a resolved promise for `value`. See [API docs](docs/api.md#whenresolve).
|
|
* Resolve/reject return something useful: `deferred.resolve` and `deferred.reject` now return a promise for the fulfilled or rejected value.
|
|
* Resolve a deferred with another promise: `deferred.resolve(promise)` - when `promise` resolves or rejects, so will `deferred`.
|
|
|
|
### 1.3.0
|
|
|
|
* Fixed a deviation from the Promises/A spec where returning undefined from a callback or errback would cause the previous value to be forwarded. See [#31](https://github.com/cujojs/when/issues/31)
|
|
* *This could be a breaking change* if you depended on this behavior. If you encounter problems, the solution is to ensure that your promise callbacks (registered either with `when()` or `.then()`) return what you intend, keeping in mind that not returning something is equivalent to returning `undefined`.
|
|
* This change also restores compatibility with the promises returned by `jQuery.get()`, which seem to reject with themselves as the rejection value. See [issue #41](https://github.com/cujojs/when/issues/43) for more information and discussion. Thanks to [@KidkArolis](https://github.com/KidkArolis) for raising the issue.
|
|
|
|
### 1.2.0
|
|
|
|
* `promise.otherwise(errback)` as a shortcut for `promise.then(null, errback)`. See discussion [here](https://github.com/cujojs/when/issues/13) and [here](https://github.com/cujojs/when/issues/29). Thanks to [@jonnyreeves](https://github.com/jonnyreeves/) for suggesting the name "otherwise".
|
|
* [when/debug](https://github.com/cujojs/when/wiki/when-debug) now detects exceptions that typically represent coding errors, such as SyntaxError, ReferenceError, etc. and propagates them to the host environment. In other words, you'll get a very loud stack trace.
|
|
|
|
### 1.1.1
|
|
|
|
* Updated [wiki](https://github.com/cujojs/when/wiki) map/reduce examples, and added simple promise forwarding example
|
|
* Fix for calling `when.any()` without a callback ([#33](https://github.com/cujojs/when/issues/33))
|
|
* Fix version number in `when.js` source ([#36](https://github.com/cujojs/when/issues/36))
|
|
|
|
### 1.1.0
|
|
|
|
* `when.all/any/some/map/reduce` can all now accept a promise for an array in addition to an actual array as input. This allows composing functions to do interesting things like `when.reduce(when.map(...))`
|
|
* `when.reject(promiseOrValue)` that returns a new, rejected promise.
|
|
* `promise.always(callback)` as a shortcut for `promise.then(callback, callback)`
|
|
* **Highly experimental** [when/debug](https://github.com/cujojs/when/wiki/when-debug) module: a drop-in replacement for the main `when` module that enables debug logging for promises created or consumed by when.js
|
|
|
|
### 1.0.4
|
|
|
|
* [Travis CI](http://travis-ci.org/cujojs/when) integration
|
|
* Fix for cancelable deferred not invoking progress callbacks. ([#24](https://github.com/cujojs/when/pull/24) Thanks [@scothis](https://github.com/scothis))
|
|
* The promise returned by `when.chain` now rejects when the input promise rejects.
|
|
|
|
### 1.0.3
|
|
|
|
* Fix for specific situation where `null` could incorrectly be used as a promise resolution value ([#23](https://github.com/cujojs/when/pull/23))
|
|
|
|
### 1.0.2
|
|
|
|
* Updated README for running unit tests in both Node and Browsers. See **Running the Unit Tests** below.
|
|
* Set package name to 'when' in package.json
|
|
|
|
### 1.0.1
|
|
|
|
* Fix for rejections propagating in some cases when they shouldn't have been ([#19](https://github.com/cujojs/when/issues/19))
|
|
* Using [buster.js](http://busterjs.org/) for unit tests now.
|
|
|
|
### 1.0.0
|
|
|
|
* First official when.js release as a part of [cujojs](https://github.com/cujojs).
|
|
* Added [when/cancelable](https://github.com/cujojs/when/wiki/when-cancelable) decorator for creating cancelable deferreds
|
|
* Added [when/delay](https://github.com/cujojs/when/wiki/when-delay) and [when/timeout](https://github.com/cujojs/when/wiki/when-timeout) helpers for creating delayed promises and promises that timeout and reject if not resolved first.
|
|
|
|
### 0.11.1
|
|
|
|
* Added [when/apply](https://github.com/cujojs/when/wiki/when-apply) helper module for using arguments-based and variadic callbacks with `when.all`, `when.some`, `when.map`, or any promise that resolves to an array. ([#14](https://github.com/cujojs/when/issues/14))
|
|
* `.then()`, `when()`, and all other methods that accept callback/errback/progress handlers will throw if you pass something that's not a function. ([#15](https://github.com/cujojs/when/issues/15))
|
|
|
|
### 0.11.0
|
|
|
|
* `when.js` now *assimilates* thenables that pass the [Promises/A duck-type test](http://wiki.commonjs.org/wiki/Promises/A), but which may not be fully Promises/A compliant, such as [jQuery's Deferred](http://api.jquery.com/category/deferred-object/) and [curl's global API](https://github.com/cujojs/curl) (See the **API at a glance** section)
|
|
* `when()`, and `when.all/some/any/map/reduce/chain()` are all now guaranteed to return a fully Promises/A compliant promise, even when their input is not compliant.
|
|
* Any non-compliant thenable returned by a callback or errback will also be assimilated to protect subsequent promises and callbacks in a promise chain, and preserve Promises/A forwarding guarantees.
|
|
|
|
|
|
### 0.10.4
|
|
|
|
* **Important Fix for some AMD build/optimizer tools**: Switching back to more verbose, builder-friendly boilerplate
|
|
* If you are using when.js 0.10.3 with the dojo or RequireJS build tools, you should update to v.10.4 as soon as possible.
|
|
|
|
### 0.10.3
|
|
|
|
**Warning**: This version will not work with most AMD build tools. You should update to 0.10.4 as soon as possible.
|
|
|
|
* Minor `package.json` updates
|
|
* Slightly smaller module boilerplate
|
|
|
|
### 0.10.2
|
|
|
|
* Performance optimizations for `when.map()` (thanks @[smitranic](https://github.com/smitranic)), especially for large arrays where the `mapFunc` is also async (i.e. returns a promise)
|
|
* `when.all/some/any/map/reduce` handle sparse arrays (thanks @[rwaldrn](https://github.com/rwldrn/))
|
|
* Other minor performance optimizations
|
|
|
|
### 0.10.1
|
|
|
|
* Minor tweaks (thanks @[johan](https://github.com/johan))
|
|
* Add missing semis that WebStorm didn't catch
|
|
* Fix DOH submodule ref, and update README with info for running unit tests
|
|
|
|
### 0.10.0
|
|
|
|
* `when.map` and `when.reduce` - just like Array.map and Array.reduce, but they operate on promises and arrays of promises
|
|
* Lots of internal size and performance optimizations
|
|
* Still only 1k!
|
|
|
|
### 0.9.4
|
|
|
|
* Important fix for break in promise chains
|
