This is a bugfix release that bumps script.aculo.us to version 1.8.1.

Mainly, this release contains some important bug fixes and optimizations in Prototype, fixes cursor keys in autocompleting text fields for IE and Safari plus fixes an issue with Effect.Morph on IE.

Popularity of Ruby language is growing. This time we want to tell you about jRails is a drop-in jQuery replacement for Prototype/script.aculo.us on Rails. Using jRails, you can get all of the same default Rails helpers for javascript functionality using the lighter jQuery library.

You can download jRails and view a lots of example here.

The final versions of Prototype 1.6.0, script.aculo.us 1.8.0, and the Prototype & script.aculo.us book are now available. Prototype 1.6.0 is the most significant update to the framework since its inception over two years ago. We’re very excited about the changes in this release, and what better way to celebrate than with an update to script.aculo.us and a book covering all the new goodness?

What’s in for you (compared to script.aculo.us 1.7):

• Prototype 1.6 (lastest trunk version)
• Complete rewrite of Ajax.InPlaceEditor and Ajax.InPlaceCollectionEditor
• Full CSS inheritance in Effect.Morph
• New core effect: Effect.Tween
• Sound: play mp3 files for sound effects; uses native playback on IE and available plugins whereever possible
• Performance improvements

This new beta of the upcoming script.aculo.us 1.7 release adds support for using the morph effects with style definitions in CSS classes:

So, first define a CSS class:

.warning {
  font-size: 15px;
  color: #f00;
  border: 4px soild #f00;
}

Then use it with .morph():

$('mydiv').morph('warning');

Thanks to Tobie Langel for this niceness. Additionally, next to the string based style strings, you can also use the style definitions you know from .setStyle() in Prototype:

$('mydiv').morph({fontSize:'20px',color:'#abcdef'});

Effects should now also play faster, provided your browser and computer is fast enough, as the maximum frames per second setting is now at 60fps vs. 25fps in earlier releases.
