Today marks the release of MooTools Core and More versions1.6.0. This is aminor revision that delivers a number of bug fixes as well as the introduction of new features.

The main new adition is Class.Thenable which is a new Class mixin that can be used in Promise style flows by using itsthen method. When implemented in a Class, it makes the class "thenable" in thePromises/A+ sense of the word, meaning it can be used in Promise style flows by using itsthen method.

The implementation, however, is more than just a "then" method. Any instance of a Class implementingClass.Thenable is aPromises/A+ compliant object (generally referred to as "a Promise") with only one exception: it is possible to reset the Class's value resolution state fully (rejecting pending reactions, and starting empty) to support a Class instance living for longer than just the lifetime of one value resolution.

Example using Request:

var request =new Request();request.send().then(function(response){ console.log(response.text); });

Example hooking into a native Promise:

var request =new Request();var promise = Promise.resolve(request);request.send();promise.then(function(response){ console.log(response.text); });

You can find this new version1.6.0 in the website or within thedist folder of the1.6.0 tag (Core).

IE warning: This will be the last version to support old IE browsers. Nextminor and/ormajor versions should be only IE11+ compatible. We might still release somepatch in the1.6.x version if needed.

Array.from deprecated, now called Array.convert: Following the conclusion of the ES6 specs we know now thatArray.from will have a different implementation than the one MooTools uses.
Because of this we renamedArray.from toArray.convert to not overwrite the Native implementation.
We kept it as it was though in thecompat layer for compatibility reasons if you really to use it still.

To keep the API consistency we changed also the name of the method inFunction,Number andString Types.
