Prototype 1.5.1 RC 3 Released

Category: Announcements, JavaScript, Library, Prototype

A new version of Protoype has dropped.

Prototype 1.5.1 RC 3 gives us features such as:

  • Ajax.Requests now supports per-request onCreate callbacks. [#8011]
  • JSON strings are automatically stripped of their security delimiters (if present) before eval. More details on this security issue here (PDF document). [#7910]
  • all toJSON methods now generate YAML-loadable JSON. [#7883]
  • Event.element now returns an extended element. [#7870]
  • Linefeed normalisation is now prevented in IE on String#escapeHTML and String#unescapeHTML for consistency with other browsers.
  • Added a new Element.childElements method (shorter alias of Element.immediateDescendants).
  • Added a new Element.firstDescendant method (same as using Element.down with no arguments).

Performance improvements:

  • Faster $$() utility and Element.getElemementsBySelector method. [#7873], [#7901]
  • Optimized, Element.down, Element.up and Element.previous DOM methods. [#7848]
  • Speed improvements of String#escapeHTML and String#unescapeHTML in IE and Safari.

And plenty of bug fixes. You can see the gory details in the change log.

I don’t think that DOM Object extension is a nice thing, since there are too many functions extension.

@Rizqi – your’re kidding right?
Prototype is PIMP. I can’t wait for this version to be finalized.

Will this version be supported on IE7 ??? unfortunately for now, no and even if I don’t like IE, my webapps must work as well on IE
