MooTools Core and More 1.5 are here!

Written By Sérgio Crisóstomo, on Monday, May 19th 2014, 4:38pm
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.

Written By Olmo Maldonado, on Tuesday, February 7th 2012, 11:30am

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.

We recommend that all users upgrade to 1.4.4 as soon as possible.

MooTools Core & More 1.3.1

Written By Christoph Pojer, on Friday, February 25th 2011, 3:05pm

The MooTools team is very happy to announce a simultaneous update of both Core and More repositories. The past year was amazing for us. We had a great hackathon in London, we gave you MooTools 1.3, added a lot of new people to our team and improved everything around the code. The results of the MooTools survey clearly showed that we are doing the right things and we intend to make MooTools even better in 2011. We spent the past weeks fixing bugs and adding new features on both projects. This is what’s new:


  • Lots (and by that I mean LOTS) of documentation improvements, clarifications and cleanups
  • Updated Slick to 1.1.5 and improved the speed of our Slick selector engine
  • Added delegation support for submit, focus, blur, reset, change and select events in MooTools More
  • If available the native JSON methods are now used in JSON.decode and JSON.encode
  • Multiple Pseudos click:relay(a):once (demo)
  • Two new pseudo events: :throttle and :pause
  • Added String.truncate to String.Extras in More
  • More than two hundred changes to increase the stability of both Core & More

I am also pleased to announce our newest addition to the MooTools More team, Jacob Thornton, who is a great developer, currently working for Twitter. He has put a substantial amount of work into making MooTools More even better.

Be sure to check out the updated demos in our new demos section.
