The GNU Hurd is a kernel developed as a replacement for the Unix kernel and designed as a set of servers that run on top of the GNU Mach microkernel and implement various system services such as file systems, network stack, file access control system. The GNU Mach microkernel provides an IPC mechanism used to organize the interaction of GNU Hurd components and build a distributed multi-server architecture.

- Implemented optional support for TCP/IP stack ;
- Added ACPI translator, which is currently used only for shutdown after system shutdown;
- Introduced PCI bus arbiter, which can be useful for correct PCI access control;
