GCC 4.7, introduced as an alternative compiler with Release 3.2, is now the primary compiler used to build DragonFly. GCC 4.4 remains on the system and still has an important role as the primary DPorts compiler. GCC 4.7 brings [OpenMP](http://http://openmp.org/) (parallel programming) support to DragonFly via libgomp as well as stack smashing protection via libssp, neither of which was supported by GCC 4.4. The newer compiler also offers improved C++ and Objective-C support, and introduces [Link-Time Optimization](http://en.wikipedia.org/wiki/Link-time_optimization) (LTO) support. ### New USB stack @@ -24,7 +26,7 @@ The next version of HAMMER, HAMMER2, is in DragonFly.
