Version 3.0.6
TestSwarm build: http://swarm.jcoglan.com/job/119/
February 20 2012
================================================================

* Allow packages to contain multiple files as a convenience
  for loading 3rd-party libraries

* Fix script loading on Adobe AIR

* Fix fetching of scripts over HTTPS in jsbuild, and fail if
  requests return a non-200 status

* Make sure Module and Method have all the Kernel methods

* Make tests raise an error if a block takes a resume-callback
  but doesn't call it after 10 seconds

* Change TestSuite.forEach so that test suites run much faster

* Show stack traces for errors during tests, and use sourceURL
  mapping to improve reporting of errros from scripts loaded
  over XHR


Version 3.0.5
TestSwarm build: http://swarm.jcoglan.com/job/109/
December 6 2011
================================================================

* Allow yields() and returns() to be used on the same stub

* Remove deprecation warnings about Node's sys module


Version 3.0.4
TestSwarm build: http://swarm.jcoglan.com/job/97/
August 18 2011
================================================================

* Add JS.load() function as shorthand method for loading files,
  and JS.cacheBust setting for bypassing the browser cache

* Make jsbuild error output nicer, e.g. don't show Node backtrace


Version 3.0.3
TestSwarm build: http://swarm.jcoglan.com/job/90/
August 15 2011
================================================================

* Allow constructors expected to be called with 'new' to be mocked
  and stubbed in JS.Test

* Enhance browser UI with user agent and success indicator and
  provide controls for running individual groups of tests

* Send entire test UI snapshot to TestSwarm rather than just a
  short status summary

* Fix serialization of objects containing circular references
  in JS.Console.convert()

* Improvements to jsbuild for managing bundles of scripts


Version 3.0.2
TestSwarm build: http://swarm.jcoglan.com/job/70/
July 16 2011
================================================================

* Exit with non-zero exit status from JS.Test.autorun() if there
  are any test failures

* Log test progress at JSON so we can pick up test results using
  PhantomJS (http://www.phantomjs.org)

* Allow post-test reports to cause the build to fail by returning
  false from report(). e.g. Coverage can cause a red build if it
  finds methods that were not called

* Use synchronous console.warn() to produce output in Node, and
  System.out.print[ln] on Rhino platforms


Version 3.0.1
TestSwarm build: http://swarm.jcoglan.com/job/31/
June 17 2011
================================================================

* Adds NPM package and jsbuild command-line program for bundling
  required modules for deployment, see
  http://jsclass.jcoglan.com/packages/bundling.html

* When using JS.require(), scripts from the same domain are
  prefetched over XHR to maximize parallel downloading

* Fixes support for negative mock expectations, e.g.
  expect(object, 'm').exactly(0)

* Fixes scheduling bugs in FakeClock so that current time remains
  correct when removing and restoring timers

* Avoids stubbing of setTimeout() inside AsyncSteps, otherwise
  it becomes very hard to use with FakeClock


Version 3.0.0
TestSwarm build: http://swarm.jcoglan.com/job/19/
February 28 2011
================================================================

* All components now run on a much wider array of platforms,
  see http://jsclass.jcoglan.com/platforms.html

* JS.Class is now tested using its own test framework, JS.Test.
  See http://jsclass.jcoglan.com/testing.html

* New libraries: Benchmark, Console, Deferrable, OrderedHash,
  Range, OrderedSet, TSort

* HashSet has become the base Set implementation, and the
  original Set implementation has been removed

* StackTrace has been totally overhauled to support extensible
  user-defined tracing functionality

* New core method Module#alias() for aliasing methods

* User-defined keyword methods using Method.keyword()

* JS.Class no longer supports subclassing the Class class

* Module#instanceMethod() returns a Method, not a Function

* Enumerable#grep() now supports selecting by type, e.g.
  items.grep(Array). It does not support functional predicates
  like items.grep(function(x) { return x == 0 }), you should use
  Enumerable#select() for this

* Objects with the same properties, and Arrays with the same
  elements are now considered equal when used as Hash keys

* MethodChain#fire() is now called MethodChain#__exec__()

* JS.Ruby has been removed

* JS.State now adds states() as a class method, rather than a
  macro in the class body. All classes using 'inline' states
  MUST call this method to declare and resolve their states


Version 2.1.5
June 5 2010
================================================================

* Adds support for Node, Narwhal and Windows Script Host to the
  JS.Package loading system.

* Adds an `autoload` macro to the package system for quickly
  configuring modules using filename conventions.

* Renames `require()` to `JS.require()` so as not to conflict
  with CommonJS module API.


Version 2.1.4
March 9 2010
================================================================

* Rewritten the package loader to use event listeners to trigger
  loading of dependencies rather than polling for readiness.

* package.js and loader.js no longer depend on or include the
  JS.Class core; you must call `require()` to use JS.Class,
  JS.Module, JS.Interface or JS.Singleton.

* Fix bug in browser package loader in environments that have
  a global `console` object with no `info()` method.


Version 2.1.3
October 10 2009
================================================================

* Fixes the load() function in the Packages DSL, and adds some
  caching to improve lookup times for finding a package by the
  name of its provided objects.

* Non-existent package errors are now defered until you require()
  an object rather than being thrown at package definition time.
  This means require() won't complain about being passed native
  objects or objects loaded by other means, as long as the
  required object does actually exist.

* MethodChain now adds instance methods from Modules, and adds
  methods that were defined *before* MethodChain was loaded.

* State now supports callSuper() to state methods imported from
  mixins; previously you could only callSuper() to the superclass.


Version 2.1.2
August 11 2009
================================================================

* LinkedList was defined twice in the stdlib.js bundle; this
  is now fixed [thanks @skim].


Version 2.1.1
July 6 2009
================================================================

* Fixes a couple of Set bugs: Set#isProperSuperset had a missing
  argument, and incomparable objects were being allowed into
  SortedSet collections.


Version 2.1.0
June 8 2009
================================================================

* New libraries: ConstantScope, Hash, HashSet.

* Improved package manager, supports parallel downloads in
  web browsers and now also works on server-side platforms
  (tested on SpiderMonkey, Rhino and V8). Also supports custom
  loader functions for integration with Google, YUI etc.

* Enumerable updated with Ruby 1.9 methods, enumerators, and
  Symbol#to_proc functionality when passing strings to iterators.
  Any object with a toFunction() method can be used as an iterator.
  Search methods now use equals() where possible.

* ObjectMethods module is now called Kernel.

* New Kernel methods: tap(), equals(), hash(), enumFor() and methods(),
  and new Module methods: instanceMethods() and match().

* The double inclusion problem is now fixed, i.e. the following
  works in JS.Class 2.1:
  
      A = new JS.Module();
      C = new JS.Class({ include: A });
      B = new JS.Module({ foo: function() { return 'B#foo' } });
      A.include(B);
      D = new JS.Class({ include: A });

      new C().foo()   // -> 'B#foo'
      new D().foo()   // -> 'B#foo'
  
  (See http://eigenclass.org/hiki/The+double+inclusion+problem)

* Ancestor and method lookups are cached for improved performance.

* Automatic generation of displayName on methods for integration
  with the WebKit debugger.

* API change: Set#classify now returns a Hash, not an Object.

* PDoc documentation for the core classes.


Version 1.6.3
March 4 2009
================================================================

* Fixes a bug caused by Function#prototype becoming a non-
  enumerable property in Safari 4, causing classes to inherit
  from themselves and leading to stack overflows.


Version 2.0.2
October 1 2008
================================================================

* The function returned by object.method('callSuper') now behaves
  correctly when called after the containing method has returned.


Version 1.6.2
October 1 2008
================================================================

* Fixes some bugs to make various forEach() methods more robust.


Version 2.0.1
September 14 2008
================================================================

* Fixes a super()-related bug in Command.

* Better handling of 'include' and 'extend' directives such
  that these are processed before all the other methods are
  added. This allows mixins to override parts of the including
  class to affect future method definitions.

* Module#include() has been fixed so that overriding it produces
  more sane behaviour with respect to classes that delegate to
  a module behind the scenes to store methods.


Version 2.0.0
August 12 2008
================================================================

* Complete rewrite of the core, including a proper implementation
  of Modules with all inheritance semantics based around this.
  Ruby-style multiple inheritance now works correctly, and
  callSuper() can call methods from mixins.

* Class and Module are now classes, and must be created using
  the 'new' keyword.

* Some backward compatibility breaks; see http://jsclass.jcoglan.com/upgrade.html

* New method: Object#__eigen__() returns an object's metaclass.

* Performance of super() calls is much improved.

* New libraries: Package, Set, SortedSet and StackTrace.

* Package provides a dependency-aware system for loading new
  JavaScript files on demand.


Version 1.6.1
April 17 2008
================================================================

* Fixes bug in Decorator and Proxy.Virtual caused by the 'klass'
  property being treated as a method and delegated.


Version 1.6.0
April 10 2008
================================================================

* Adds a DSL for defining classes in a more Ruby-like way using
  procedures rather than declarations (experimental).

* New libraries: Forwardable, State.

* The extended() hook is now supported.

* The 'implement' directive is no longer supported.


Version 1.5.0
February 25 2008
================================================================

* Adds a standard library, including Command, Comparable,
  Decorator, Enumerable, LinkedList, MethodChain, Observable
  and Proxy.Virtual.

* Renames _super() to callSuper() to avoid problems with PackR's
  private variable shrinking.

* Adds an Object#wait() method that calls a MethodChain on the
  object using setTimeout().


Version 1.0.1
January 14 2008
================================================================

* Memoizes calls to Object#method() so that the same function
  object is returned each time.


Version 1.0.0
January 4 2008
================================================================

* Singleton methods that call super() are now supported.

* Object#is_a() has been renamed to Object#isA().

* Classes now support inherited() and included() hooks.

* Adds Interface class for easier duck-typing checks across
  several methods.

* New directive 'implement' can be used to check that a class
  implements some interfaces.

* Singletons are now supported as class-like definitions that
  yield a single object.

* Module has been added as a way to protect sets of methods by
  wrapping them in a closure.

* Removes the bindMethods class flag in favour of the more
  efficient and Ruby-like Ojbect#method(). This can also be
  used on classes to get bound class methods.

* Exceptions thrown while calling super are no longer swallowed
  inside the framework.

* Class#method() is now Class#instanceMethod.


Version 0.9.2
November 13 2007
================================================================

* Fixes bug caused by multiple methods in the same call stack
  clobbering _super().

* Fixes some inheritance bugs related to class methods and
  built-in instance methods.

* Improves performance by bootstrapping JavaScript's prototypes
  for instance method inheritance.

* Allows inheritance from non-JS.Class-based classes.


Version 0.9.1
November 12 2007
================================================================

* Improves performance by checking whether methods use _super()
  and only wrapping where necessary.


Version 0.9.0
November 11 2007
================================================================

* Initial release. Features single inheritance and _super().
