• Various doc fixes (#971, #980)

v1.5.0

• auto now accepts an optional concurrency argument to limit the number of running tasks (#637)
• Added queue#workersList(), to retrieve the list of currently running tasks. (#891)
• Various code simplifications (#896, #904)
• Various doc fixes (#890, #894, #903, #905, #912)

v1.4.2

• Ensure coverage files don't get published on npm (#879)

v1.4.1

• Add in overlooked detectLimit method (#866)
• Removed unnecessary files from npm releases (#861)
• Removed usage of a reserved word to prevent in older environments (#870)

v1.4.0

• asyncify now supports promises (#840)
• Added Limit versions of filter and reject (#836)
• Add Limit versions of detect, some and every (#828, #829)
• some, every and detect now short circuit early (#828, #829)
• Improve detection of the global object (#804), enabling use in WebWorkers
• whilst now called with arguments from iterator (#823)
• during now gets called with arguments from iterator (#824)
• Code simplifications and optimizations aplenty (diff)

v1.3.0

New Features:

• Added constant
• Added asyncify/wrapSync for making sync functions work with callbacks. (#671, #806)
• Added during and doDuring, which are like whilst with an async truth test. (#800)
• retry now accepts an interval parameter to specify a delay between retries. (#793)
• async should work better in Web Workers due to better root detection (#804)
• Callbacks are now optional in whilst, doWhilst, until, and doUntil (#642)
• Various internal updates (#786, #801, #802, #803)
• Various doc fixes (#790, #794)

Bug Fixes:

• cargo now exposes the payload size, and cargo.payload can be changed on the fly after the cargo is created. (#740, #744, #783)

v1.2.1

Bug Fix:

• Small regression with synchronous iterator behavior in eachSeries with a 1-element array. Before 1.1.0, eachSeries's callback was called on the same tick, which this patch restores. In 2.0.0, it will be called on the next tick. (#782)

v1.2.0

New Features:

• Added timesLimit (#743)
• concurrency can be changed after initialization in queue by setting q.concurrency. The new concurrency will be reflected the next time a task is processed. (#747, #772)

Bug Fixes:

• Fixed a regression in each and family with empty arrays that have additional properties. (#775, #777)

v1.1.1

Bug Fix:

• Small regression with synchronous iterator behavior in eachSeries with a 1-element array. Before 1.1.0, eachSeries's callback was called on the same tick, which this patch restores. In 2.0.0, it will be called on the next tick. (#782)

v1.1.0

New Features:

• cargo now supports all of the same methods and event callbacks as queue.
• Added ensureAsync - A wrapper that ensures an async function calls its callback on a later tick. (#769)
• Optimized map, eachOf, and waterfall families of functions
• Passing a null or undefined array to map, each, parallel and families will be treated as an empty array (#667).
• The callback is now optional for the composed results of compose and seq. (#618)
• Reduced file size by 4kb, (minified version by 1kb)
• Added code coverage through nyc and coveralls (#768)

Bug Fixes:

• forever will no longer stack overflow with a synchronous iterator (#622)
• eachLimit and other limit functions will stop iterating once an error occurs (#754)
• Always pass null in callbacks when there is no error (#439)
• Ensure proper conditions when calling drain() after pushing an empty data set to a queue (#668)
• each and family will properly handle an empty array (#578)
• eachSeries and family will finish if the underlying array is modified during execution (#557)
• queue will throw if a non-function is passed to q.push() (#593)
• Doc fixes (#629, #766)
