What are the Dexterity and Archetypes gotchas in Plone 4.1?

In a recent question, toutpt said:

Dexterity needs Plone4.1 to play well с содержанием архетипов и иметь все функция Plone (история, разница, блокировка, ...)

I'm thinking of using Dexterity in a new site, alongside standard Archetypes objects like Pages, Files and so on. However, I've not been able to find a page listing the possible issues this may throw up.

I know there have been issues with Dexterity/Archetypes playing well together on a site, for example referencing between the two styles of content types. I'm wondering whether this is still an issue (it looks like toutpt may have fixed it), and what the other gotchas I should be aware of before diving in with Dexterity.

Initially my thought is to use Dexterity 1.0 and the version of Archetypes that ships with Plone 4.1, but I'm open to suggestions (e.g., versions 1.0-next for Dexterity).
