Google drupal 7.12 and find the drupal.org/node/1425104 - posts dated 2nd Feb 2012 posted by webchick discuss the 7.12 problems. I found this too late. Roger
The drupal document you cite lists changes made to 7.12 since 7.10. I don't see that it says it's unfit for use. Also, and it might be relevant, the post is dated February 1, 2012 at 10:15pm. It doesn't say what timezone, it might be adjusting the time to reflect my presumed TZ based on my IP address.
I do see a link to 7.11 and the link seems to be in good order. The 7.11 page does not say what it's different from, it just lists one change.
