I agree with blargh314's answer. Disclosing few details about the divorces during the dating is needed, I would feel, for most potential people. Some might not care at all, but... I sometimes joke that people are allowed to have one crazy ex. Well, as a joke, it's obviously very very exaggerated generalization. But point still stands. Divorces and break ups happen, people are people after all. For a future date what is important from their point of view, is to get fair idea why would this person's relationships end. It is after all something that is big part of the person's relationship characteristics. If you start dating a person whose all exes were "batpoop crazy", either they have very poor taste or the problem is with the person him/herself. On the other hand, sometimes people grow apart, and sometimes everybody misjudges person's character (or the traits pop up later). That is the difference most would in my opinion want to know. Is it the case of "life happens to everybody" or "I'm determined to repeat these same mistakes in my every relationship". Some people are judgier than other, but I think quite many just want to spare themselves of heart break.
So, divorce details, not first date material, but during the "getting to know period" at least bit of them should be shared. However, the other things you mention, the wanting to have adult relationship, take it slowly without official commitments and not bringing kid to it anytime soon is first date material. Or dating profile material if some kind of external aids are used to find potential dates.
