v2.0.0

#What's new in 2.0

• Resource management - never leak resources again
• Promisification on steroids - entire modules can now be promisified with one line of code
• .map(), .each(), .filter(), .reduce() reimagined from simple sugar to powerful concurrency coordination tools
• API Documentation has been reorganized and more elaborate examples added
• Deprecated progression and deferreds
• Improved performance and readability

Features:

• Added using() and disposer()
• .map() now calls the handler as soon as items in the input array become fulfilled
• Added a concurrency option to .map()
• .filter() now calls the handler as soon as items in the input array become fulfilled
• Added a concurrency option to .filter()
• .reduce() now calls the handler as soon as items in the input array become fulfilled, but in-order
• Added .each()
• Promise.resolve() behaves like Promise.cast. Promise.cast deprecated.
• Synchronous inspection: Removed .inspect(), added .value() and .reason()
• Promise.join() now takes a function as the last argument
• Added Promise.setScheduler()
• .cancel() supports a custom cancellation reason
• .timeout() now cancels the promise instead of rejecting it
• .nodeify() now supports passing multiple success results when mapping promises to nodebacks
• Added suffix and filter options to Promise.promisifyAll()

Breaking changes:

• Sparse array holes are not skipped by collection methods but treated as existing elements with undefined value
• .map() and .filter() do not call the given mapper or filterer function in any specific order
• Removed the .inspect() method
• Yielding an array from a coroutine is not supported by default. You can use coroutine.addYieldHandler() to configure the old behavior (or any behavior you want).
• .any() and .some() no longer use an array as the rejection reason. AggregateError is used instead.
