Max Vernon has a script to help us find what new objects now exist on your database:
The code below provides a list of all SQL Server objects created in the past “x” number of days. Dynamic T-SQL is used to construct a query for each database, including system databases. Each query provides the schema, name, and date created for each object listed, along with the object type description.
This looks quite useful for auditing. You might want to filter out tempdb on a real system, though.
