It would be nice to have a stable release to provide site builders more certainty that the module will get an SA for any security issues. Please feel free to update this issue summary to include links to issues to fix prior to that release.

As of this post there seem to be 5 open bugs for 6.x, but none critical:

2 for 6.x-2.x-dev
2 for 6.x-2.1-beta8
1 for 6.x-3.x-dev: http://drupal.org/node/1116454

Thanks for your time!
