So far, everything that I have tested is working ok. I need to do a couple of more tests on another site to really be certain.
One issue though I have noticed since installing these betas (Form Builder and Dynamic Connections), under the WebAssist menu in Dreamweaver, I get the item "Get More Extensions" repeated twice so I have three of them. Minor bug and I'm not completely sure it is tied to these betas but only noticed it since installing the betas.
