2.0

[jsor]

The goal is to streamline the API and to make it more compliant with other promise libraries and especially with the new upcoming ES6 promises specification.

• Add standalone Promise class.
  Provides an alternative promise-creation API that has the same power as the deferred concept, but without introducing another conceptual entity plus it's identical with the Promise object from the upcoming ES6 promises specification.
• Add new React\Promise\race() function.
  Initiates a competitive race that allows one winner. Returns a promise which is resolved in the same way the first settled promise resolves (See also ES6 spec).
• BC break: Bump minimum PHP version to PHP 5.4.
  Allows the callable typehint (see a4d6358, removes the hacky error triggering from a0f23cb). $this can be used in anonymous functions (example).
• BC break: Remove ResolverInterface and PromiseInterface from Deferred.
  Usage of Deferred::then has been always discouraged and it only existed because it was used by the (now removed) DeferredPromise class. Removed the ResolverInterface entirely for the sake of simplicity. I haven't come across any single userland usage.
• BC break: Change signature of PromiseInterface.
  Added the callable typehint and renamed arguments to be compliant with the ES6 promises specification and Promise/A+ naming conventions.
• BC break: Remove When and Util classes and move static methods to functions.
  FFTW (Functions For The Win).
• BC break: FulfilledPromise and RejectedPromise now throw an exception when initialized with a promise instead of a value/reason.
  This is more a bugfix than a BC break. Since FulfilledPromise and RejectedPromise are now documented in the API docs, i fixed it. In 1.0, we only documented When::resolve() and When::reject() as public API which only creates instances if value/reason was not a promise.
• BC break: React\Promise\Deferred::resolve() and React\Promise\Deferred::reject() no longer return a promise.

[igorw]

can just be [$this, 'resolve']

[jsor]

No, because resolve is private. The closure is needed for the class scope.

[igorw]

gotcha!

[igorw]

could this be simply [$this, 'resolve']?

[jsor]

See #12 (comment) :)

LOL again? :) /me slaps himself...
