Release update

[Andrus Adamchik]

I am in the process of creating the M12 release. All major things are  
in. Now I am testing it on various databases and fixing db-specific  
issues.

I thought we could ship the docs from Wiki with M12, but the PDF  
export is too unorganized (chapters are sorted alphabetically by name  
- very confusing). Postponing the doc system switch till beta (I'll  
probably open a Jira task to track progress on that).

Almost there....
