Changelog

1.2.0

• promise.otherwise(errback) as a shortcut for promise.then(null, errback). See discussion here and here. Thanks to @jonnyreeves for suggesting the name "otherwise".
• 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 map/reduce examples, and added simple promise forwarding example
• Fix for calling when.any() without a callback (#33)
• Fix version number in when.js source (#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 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 integration
• Fix for cancelable deferred not invoking progress callbacks. (#24 Thanks @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)

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)
• Using buster.js for unit tests now.

1.0.0

• First official when.js release as a part of cujojs.
• Added when/cancelable decorator for creating cancelable deferreds
• Added when/delay and when/timeout helpers for creating delayed promises and promises that timeout and reject if not resolved first.

0.11.1

• Added 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)
• .then(), when(), and all other methods that accept callback/errback/progress handlers will throw if you pass something that's not a function. (#15)

0.11.0

• when.js now assimilates thenables that pass the Promises/A duck-type test, but which may not be fully Promises/A compliant, such as jQuery's Deferred and curl's global API (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), 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)
• Other minor performance optimizations

0.10.1

• Minor tweaks (thanks @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
