It appears to be broken still. The bindings panel works when dealing with the web page itself, you just can't access it from any other user interfaces like binding columns in insert and update server behaviors and dynamic lists. Basically any time you would access bindings by clicking on the lightning bolt.
And the Database window works for adding a connection, but they never show in that window so you can't edit it once it has been created and you can't click the Define.. button to define a connection from within another interface like the recordset window.
You can work around these issues, but they are definitely still broken. It wouldn't prevent you from creating a connection, recordset, and repeated region as long as you avoid/ignore those specific things that don't work.
