Views broken after update (teaser don't work, html tags appears)

Hi there,

I just make some updates (drupal 5.5, view 1.6 (I was on 1.6 beta 4 before).

The update don't show errors, but Some views I setted up are corrupted. They show all the nodes, not only teaser as they should do and they show the HTML tags in my nodes.

I cannot show you because I had to disable them on my production website but it's ugly !

Help please !!
