1.5.1 is out!

Written By Sérgio Crisóstomo, on Friday, August 29th 2014, 7:25am

Today we release MooTools Core and More versions 1.5.1. This continues our improvement work for both Core and More and introduces also some features that were in the queue for being added. This release fixes also a regression related to the mousewheel event.
When preparing the 1.5 release we decided that Core 1.5.x will work with More 1.5.x. This means that, inside the 1.5 space, versions should be compatible and you might be seeing Core or More releases that are not simultaneous.

In 1.5.1 we added a new dist/ folder in Core, present at the tagged commit, for those who want the Core source, as well as a needed update so you can get MooTools via Bower.

Worth a notice is also the new MooTools Packager. MooTools has always been about modularity, and for those of you that want to choose which modules to use you can now use the new MooTools Packager (for Node.js/Grunt), as well as the website builder. The new Packager allows to compile source files from the dependencies in the YAML header. You can find it on GitHub and NPM.

The main things in this release are:


  • Mousewheel regression fix for Chrome and Firefox. (link)
  • DOMEvent’s wheel property now listens for DOM3 wheel event also. (link)
  • IE8 iFrame leak fix. (link)
  • Added postMessage to NativeEvents. (link)

MooTools Core and More 1.5 are here!

More stable and well tested than ever

1.5 is a HUGE bug fix release with roughly 240 commits addressing new browsers that have entered the market as well as new features in the JavaScript language. The team spent a ton of time instrumenting the tests to run against Travis CI and Sauce Labs so that the source code would be easier to test. This will help to make new contributions, fixes and features to the framework and release much more rapidly.

It’s easy to underestimate the value of all the work that went into the project over the past two months.


MooTools 1.4.5 Released

Written By Arian Stolwijk, on Sunday, February 26th 2012, 9:00pm

MooTools Core 1.4.5 is a maintenance release for the 1.4 branch.

1.4.5 brings a critical bugfix for Fx.CSS which caused many troubles for tweening and morphing your element styles. The bug was caused by a fix in 1.4.4 which should improve animating other length units like % or em (see #2160. Many of you noticed the bug and filled bugreports and also helped us testing this new release.

We have improved our tests and are planning to freeze the code for a new release for a longer period so we can gather more feedback to prevent potential regressions. If you’re interested in testing a new release in your application, you can ping us on IRC (#mootools on, Twitter (@mootools / @astolwijk) or in the MooTools User Group.

Today we release MooTools Core 1.4.4 which is a critical maintenance release. 1.4.3 release introduced a bug as a result of fixing another bug. Specifically, 1.4.3 did not allow custom attributes (e.g. data- or non-standard attributes). See this issue for a full explanation and solution.
