1.6.0 is out!

Written by Sérgio Crisóstomo on 14 January 2016 – Posted under all, releasesComments

Today marks the release of MooTools Core and More versions 1.6.0. This is a minor 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 its then method. When implemented in a Class, it makes the class "thenable" in the Promises/A+ sense of the word, meaning it can be used in Promise style flows by using its then method.

The implementation, however, is more than just a "then" method. Any instance of a Class implementing Class.Thenable is a Promises/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);
promise.then(function(response){ console.log(response.text); });

You can find this new version 1.6.0 in the website or within the dist folder of the 1.6.0 tag (Core).


IE warning: This will be the last version to support old IE browsers. Next minor and/or major versions should be only IE11+ compatible. We might still release some patch in the 1.6.x version if needed.

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

To keep the API consistency we changed also the name of the method in Function, Number and String Types.
