+ The coroutine switch adds some operations, because PDO changes the global error handler at IO request time
+ Support for creating coroutines using internal C functions
+ Allow closed sockets across coroutines
+ Improve server-side SSL certificate verification
+ Enhanced coroutine iterators and stack traces
