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
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 freenode.net), 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.
We recommend that all users upgrade to 1.4.4 as soon as possible.
