Quote:\vnote{since November 2013, we switched from an old, intrusive implementation
of smart pointers to a more standard one: either Boost {\vcode shared\_ptr<>}
implementation or standard C++ one if we are compiling in C++11. Here are the
changes:

{\vcode vmime::ref <>} is replaced with {\vcode vmime:hared\_ptr <>}

{\vcode vmime::weak\_ref <>} is replaced with {\vcode vmime::weak\_ptr <>}

{\vcode vmime::create <>} is replaced with {\vcode vmime::make\_shared <>}
}
