[Boost-users] [ptr_container] usage of auto_type

Hello,

I have the following code fragment:

typedef boost::ptr_vector<T>                vector_t;
typedef message_vector_t::auto_type     auto_t;

....
vector_t v;
{
   auto_t x(new T)
   // do something with x
   v.push_back(x.release()); // here rise my question
}

according 
http://www.boost.org/doc/libs/1_53_0/libs/ptr_container/doc/examples.html #6

Do I have to release x all the time?

E.g. I want to use it in the loop, where at the end I have to push_back 
the value, where for my understanding x goes out of scope and hence is 
released automatically. After studying the header, there is no push_back 
for auto_type (which is  static_move_ptr), but for std::auto_ptr (which 
is imo deprecated in C++11) and T (which converts it into an auto_type 
again). Is it correct or do I miss something?
