For those of you who like the new Ajax tags of Colfusion 8 the framework, ExtJS, has released the Alpha version of their next major release.
This release is a rather large upgrade to the code base that Coldfusion uses and fully separates its reliance or dependence on other frameworks (yahoo ui toolkit for example).
The host of new features are too many to go into here so you can read about the major and exciting new features here. You can also read more about the general release news on their blog.
All I can say is that Jack Slocum and his crew do a fantastic job and I am continually impressed with the quality and level of their work. Add on top of that the three licensing options (open source, oem/reseller, and commercial) and you end up with a product that everyone can use.
An important thing to note is that this release while extensive has not significantly increased the size of the library. The whole library measures in at 522kb (thats everything you need) and it is possible to reduce that size rather significantly by importing only the library files that you need for a specific task. Though that being said the general practice is to include the ext-all.js file and be done with it.
