So, Drupal 7.0 Alpha 3 has been released on 21 Mar 2010. That's very close to a Beta and a stable release.
That's very exciting news indeed.
Besides CCK, Views and a number of well established modules as a part of the core, it has a large number of improvements in terms of usability, security and performance. Unfortunately, looks like Panels, a very cool module that for basically doing complex visual layouts won't be a part of D7. Hopefully, a release for D7 as a standalone module will be available soon.
The community is trying to meet the D7 lunch with updated versions of the various modules. Ubercart is such an example, and this means very soon we'll be able to build state-of-the-art ecommerce websites with more flexibility, better performance and faster than before.
Many thank to all those involved in this great open-source endeavor.
