The Dojo foundation has released version 1.0 of the Dojo javascript toolkit. Dojo is one of the most complete javascript toolkit available, with of course ajax functionalities but also internationlisation, cryptography, offline capabilities and a widget system. It supports Firefox, Safari, Internet Explorer and Opera browsers.

It is used in products by AOL, BEA, IBM and Sun amongst others.

jMaki is a client/server framework to ease development of Ajax applications, and it abstracts much of the javascript and CSS needed while covering several javascript libraries as Yahoo's YUI, Dojo and Scriptaculous. jMaki is made of both client side components (layout, client services and runtime as well as a widget model) and server side components ( server runtime and XmlHttpProxy).

Quickstart guides are available for Java and PHP, but efforts are also underway to make it available in Ruby on Rails

Version 1.0 of jMaki is now available for download.
