Indeed, it needs some luck to find it.
Open your layer properties -> Attributes Form -> click on the field you 
want to habv automatic update in the left part of the window.
In the right part of the window, the properties of your attribute field 
show up.
At the very end, there is the section "Default".
Here you can enter any forumla for calculating a default value on 
feature creation.
When marking the checkbox "Apply default value on updates", the formula 
is recalculated instantly as with the plugin.

Hope that helps,
Bernd

p.s. this is the wrong list. the correct one is qgis-user at lists.osgeo.org
