Today Spry 1.6 was released. Along with the new build is a new website/portal which contains links to demos, docs and more. Also, the Spry Team has an updated blog entry on the 1.6 release:

Spry 1.6 and the Dreamweaver Updater

One of my favorite bits from the entry:

We have included packed and minimized javascript files for everything. This gets all of us some significant file size savings, for example: SpryData.js: 128kb to 41Kb. SpryEffects.js: 77 to 29.

I'll try to do some demos of Spry 1.6 later on during the week, but definitely check it out now!
