Finally we have a stable, official release of GCC 4.4
. This major update to the GNU Compiler Collection brings forth Graphite, which is a framework for providing loop optimizations and eventually will be used to provide automatic parallelization support. While still experimental, there is also improved support for C++0x, new compiler improvements, and various language-specific enhancements.
The major GCC 4.4 changes can be read about at GNU.org
. The release announcement can be found on their mailing list
