The Ubercart and commerce modules are both growing in user base for Drupal 7. In April of 2011 I wrote about e-commerce for Drupal 7 at that time Ubercart had 900 sites on Drupal 7 while commerce had 500 sites.
So, this site has been around since December 28th of 2011. At the outset I invited a few friends like Ezra and Ben to help test it out. On today's Drupal Easy Podcast the site was mentioned which brought some new users so I guess this is the launch.
The Chaos Tools module currently has version 1 of release candidate before the final release (i.e. 7.x-1.0-rc1). Views recently had it's 7.x-3.0 stable release. It's likely that Chaos Tools stable will come in the near future. When will the release node of the first stable release of Chaos Tools for Drupal 7 be created?
