As people suggested (http://www.siwapp.org/blog/2009/12/new-system-requirements-for-0-3-release/#comment-277) the use of triggers, and the MySQL 5.1.6 or newer as a requirement was a bad idea. Well, today we’ve fixed this. No more specific MySQL version will be needed, and everything about triggers has been deleted.
I think this will ease the installation on many platforms.
