Dojo version 1.0, an open source JavaScript toolkit for Ajax development that can be used to build rich Web 2.0 applications has been released by The Dojo Foundation today. This latest release, version 1.0 is also available to be used from the AOL’s Content Delivery Network, which means users that loading Dojo from this location of AOL do not need to download or install this version to their servers, however the use of script tag to load the Dojo is required, as stated on the Dojo’s latest blog entry.

Dojo is JavaScript based but supports Ajax, progressive enhancement, animations, as well as some high-quality widgets and extension modules. Since its first inception in 2004, Dojo has became a key part of products for some renown organizations such as AOL, BEA, IBM, and Sun Microsystems. It currently supports variety of browser types and versions that include Internet Explorer, Firefox, Safari and Opera. The adoption of Dojo continues to grow and the most notable mashup maker that developed by IBM in using Dojo is QEDWiki.

This version of Dojo is comprised of three main technologies, Dojo Core, Dijit and DojoX. Dojo Core provides functionality to overcome the huge differences in performance between brands and vintages of browsers. Dijit is a collection of rich user interface controls and DojoX provides native vector graphics, charting, offline mode, Comet support, and many other extensions.
