The NetBSD Project has released NetBSD 5.0 into the wild today, marking the operating system's first major release since 2007.
Among 5.0's features is a rewritten threading subsystem optimized for multi-core and multiprocessor systems. Multi-threaded apps can now efficiently make use of one or more CPU or core, the team said. NetBSD's kernel has been improved to include a kernel preemption, a rewritten scheduler implementation, and real-time scheduler extensions.
Other improvements include metadata journaling for FFS file systems, a power management framework, the jemalloc memory allocator, and X.Org X11 instead of XFree86 on a number of ports.
The OS is available for download along with a complete list of new features and updates is available here.
Meanwhile, Mandriva has launched Mandriva Linux 2009 Spring in KDE, GNOME, or LXDE, and X.Org flavors.
The open source publisher promises up to 25 per cent faster boots as well as much more responsive shut-down, hibernate, suspend, and resume operations.
Other improvements include optimization of the Mandriva Control Center and support for the EXT4 file system.
