<li><p id="change-0.1.5-0"><span class="target" id="change-2ca8013d56b6dab07a13fa06df401dc9"></span><p>added SQLSession concept to SQLEngine. this object keeps track of retrieving a
connection from the connection pool as well as an in-progress transaction.
methods push_session() and pop_session() added to SQLEngine which push/pop a new
SQLSession onto the engine, allowing operation upon a second connection “nested”
within the previous one, allowing nested transactions. Other tricks are sure to
come later regarding SQLSession.</p>

list of engines for which push_session()/pop_session() will be called each time
this Session becomes the active session (via objectstore.push_session() or
equivalent). This allows a unit of work Session to take advantage of the nested
transaction feature without explicitly calling push_session/pop_session on the
engine.</p>
