开发版FreeBSD 8.0-BETA4

        FreeBSD是一份UNIX操作系统，它面向i386、IA-64、PC-98、Alpha/AXP及UltraSPARC平台。它基于加州伯克利大学的4.4 BSD-Lite发布，并带有一些4.4 BSD-Lite2增强。它还非直接地基于William Jolitz的port，这源于加州伯克利大学i386化的“Net/2”也即“386BSD”，尽管386BSD中只有非常少的代码遗留下来。FreeBSD被遍布全世界的公司、Internet服务提供商、研究人员、计算机专家、学生，以及家庭用户用于他们的工作、教学和娱乐之中。

        Ken Smith has announced the availability of the fourth beta release of FreeBSD 8.0: "The fourth and most likely final BETA build for the FreeBSD 8.0 release cycle is now available. Since BETA3 many bugs that were identified from testing done so far were addressed. Some of the bigger issues were an mbuf leak along with work done in the general IPv6, jail, and USB subsystems. Issues in other areas have been addressed as well. Due to the issues identified in this early phase of testing, the schedule for release has been pushed back. The current target for the release itself is September 29th, with two RC builds between now and then. ISO images for all supported architectures are available on the FTP sites and a 'memory stick' images are available for the amd64 and i386 architectures."
