[support] Get thee to Drupal 7

While discussing a rebuild of a fairly simple CMS site yesterday I was asked questions about moving to Drupal7.

--- There are many alpha and beta versions, Drupal7 beta 3 and alpha 8 so which is the most bug free latest version to install? -- Does Drupal 7, the recommended download have all the bug fixes of the alpha and beta versions? -- There seem to be no new releases or bug fixes over the past months, does this mean drupal 7 is good to go in production.

Can someone please advise me on this. Thanks in advance Roger

PS. I have both Drupal 7 stable and Drupal 7 beta 3 on my home pc, both seem to work well but I could not answer those questions. Thanks R
