+If your C++ environment implements C++11 or later, thrift will automatically use
+std::shared_ptr.  Otherwise you will need the boost library to provide a shared_ptr
+implementation for C++ environments pre-C++11.  If you are linking against code

+variable FORCE_BOOST_SMART_PTR for your build of thrift to make it use boost instead
+of std for a number of memory related classes.  See thrift/stdcxx.h for more.

+# Breaking Changes
+
+## 0.11.0
+
+Older versions of thrift depended on the <boost/smart_ptr.hpp> classes which
+were used in thrift headers to define interfaces.  Thrift now detects C++11
+at build time and will prefer to use <memory> classes from C++11 instead.
+You can force the library to build with boost memory classes by defining the
+preprocessor macro `FORCE_BOOST_SMART_PTR`.  (THRIFT-2221)
+
+In the pthread mutex implementation, the contention profiling code was enabled
+by default in all builds.  This changed to be disabled by default.  (THRIFT-4151)
+
+In older releases, if a TSSLSocketFactory's lifetime was not at least as long
+as the TSSLSockets it created, we silently reverted openssl to unsafe multithread behavior
+and so the results were undefined.  Changes were made in 0.11.0 that cause either an
+assertion or a core instead of undefined behavior.  The lifetime of a TSSLSocketFactory
+*must* be longer than any TSSLSocket that it creates, otherwise openssl will be cleaned
+up too early.  If the static boolean is set to disable openssl initialization and
+cleanup and leave it up to the consuming application, this requirement is not needed.
