Security updates with only the security update are released as previous version +1 and all other changes including the security update is released as previous version +2. Since previous version in this case is 7.10 then 7.11 only contains the security update and 7.12 contains all updates since 7.10.

I updated several sites yesterday to 7.12 without any issue. They are continuing to work as expected. However I do not use drush and cannot speak to how that may have affected Roger's sites. Ah yes. I believe Drush is the problem here. I played in Fedora 16 fresh install last night trying to understand the Drupal 7.10 - 7.12 issues and7.12 is fine - provided- that the install is done manually, ie manually copying over everything except the /sites folder. During experimentation I uncovered another gotcha that I do not yet understand. brief example: mysqldump a working database Create an empty database in mysql with the same name user and password as the mysqldump file. mysql -uroot -p newdatabase < old.sql to recreate the database. After installing Drupal with a dummy database, install all the modules and themes as per the original. All works fine. Go to settings.php and change the database, username and password to the installed mysqldump database and the new installation starts with the mysqldump database.

At least that's how it has worked for me previously. However with the sandpit Fedora 16 site, all I get is a blank browser, regardless of whether both or either drupals are set to maintenance mode or not. More testing today Cheers Roger
