Lots of things have been happening in DojoX lately, both big and small. I'll leave it to Pete and Adam to talk about some of the widget-based improvements that have been making their way into the codebase, but I'll talk real quick about some of the other things that have landed recently, and some upcoming things to look for.
Speed improvements to Blowfish
Thanks to a submission by Peter Wood, Blowfish now performs about 4 times faster than it used to; some clever refactoring and much simpler uint math functions have gone a long ways towards making the algorithm much more useful. On Safari 3, with a 2.4GHz MacBookPro, the unit tests are averaging about 100ms per operation; previously they were somewhere in the range of 500ms or so. Kudos to Mr. Wood for the shout out!
Curved lines now available in DojoX Charting
During DDD/IV, I was quietly hacking away on a number of things in the back of the room while a lot of great presentations were going on; one of the things I added (at Eugene's request) was to enable curved lines (based on this article) in the charting engine. So...if you're using the nightlies, all you need to do is add a "tension" property to the keyword arguments object you pass to a plot. The higher the tension, the tighter the curve. A tension of 0 means that you do not want the curve; this is the default setting.
In practice, I've found that a tension of 3 yields the nicest curves; not too tight but not too loose.
Take a look at the unit tests; charts #3, #11, #12 and #28 all show the tension in place. Note that #11 and #12 are stacked charts; curves have been enabled on stacks as well.
DojoX Sketch has landed.
A new project called "Sketch" landed in DojoX about a week and a half ago; donated by TeamPatent and ported to Dojo 1.0 by Liu Cougar, it's a general tool for annotating figures with a full undo stack. Take a look at the test and play. You'll notice that the SVG document in the bottom text area updates with every action on the drawing.
Color Generator has been finalized.
Another small "under-the-radar" set of additions to DojoX include DojoX color, an extension of the dojo.Color constructor. In addition to adding conversion methods to HSL, HSV, CMY and CMYK, there is a Generator that allows you to create a palette of colors based on several well-known generation rules. Included rules are analogous, monochromatic, triadic, complementary, split complementary, compound and shades, all loosely based on the rules at Adobe's Kuler tool. To use the generator, all you need to do is pass it a keyword argument with a base color, and the Generator will do the rest for you.
Take a look at the unit test for examples.
Upcoming updates and additions
Brad Neuberg starting hacking again on his Flash storage solutions during DDD/IV, and in running some performance tests he was pleasantly surprised to find that Adobe has fixed the serialization problems with Flash's ExternalInterface with the latest version of the Flash Player. What this means is that a good portion of the code currently in dojox.flash can be eliminated, and the Flash Storage provider can be vastly simplified and updated. Look for this in the near future, as well as some updates to Dojo Offline.
I've also quietly added/begun a new project called DojoX A/V; right now, this consists solely of a pair of base methods to embed both Flash and Quicktime on the fly but will soon include a number of things you can use on your own pages, such as a Jukebox and a Tuner. The bigger news here is that there is the beginnings of a partial port of some of the Dojo base to AS2 (including console pass-throughs, the event system (i.e. connect), and a number of the lang constructs) in order to support some of the A/V stuff well, all compiled using MTASC. All coming soon!
There's a lot more exciting news revolving around the entire project, so keep an eye out!

Sketech plus Comet = collaborative drawing
It should also be noted that Roberto Saccon has done the early work to connect Sketch with a Comet server to enable collaborative drawing.
