+We're pleased to announce new releases!
+ * **GNU Hurd 0.9**,
+ [NEWS](
+ Version 0.9 (2016-12-18)
+ The 'boot' program can now be run as unprivileged user, allowing any
+ user to create unprivileged Subhurds.
+ An ethernet multiplexer (eth-multiplexer translator) has been merged
+ into this repository. This is a network multiplexer that makes
+ available virtual interfaces, and routes traffic between these and a
+ real ethernet interface. It uses the Berkeley Packet Filter library
+ (libbpf), which has also been merged. The ethernet multiplexer now
+ generates and uses stable pseudo-random ethernet addresses for the
+ virtual interfaces.
+ As usual, bugs have been fixed throughout the code, notably in
+ libpager and ext2fs which now gracefully handles running out of space.
+ Further compatibility fixes have been applied (for compliance to
+ standards such as POSIX).
+ Release tarballs may be downloaded from <>,

+ The [[**GNU Hurd**|hurd]] is the GNU project's replacement for the [[Unix]]
+ kernel. It is a collection of [[servers|hurd/translator]] that run on the
+ Mach microkernel to implement file systems, network protocols, file access
+ control, and other features that are implemented by the Unix kernel or
+ similar kernels (such as Linux). More detailed: [[hurd/documentation]],
+ [[hurd/what_is_the_GNU_Hurd]].
+ * **GNU Mach 1.8**,
+ [NEWS](
+ Version 1.8 (2016-12-18)
+ The memory management system was extensively reworked. A new type for
+ physical addresses is now used where appropriate, and the system can
+ make use of the high memory segment. Many paging issues have been
+ addressed, and as a result the system handles low memory situations
+ more gracefully now.
+ The virtual memory system now uses a red-black tree for allocations,
+ and as a result it now supports tasks with tens of thousands of
+ mappings.
+ Debugging and error reporting has been improved. Among other things
+ the VM maps are now augmented with names that are used in error
+ messages, panics and assertions point to their locations, the lock
+ debugging mechanism has been fixed, and the kernel debugger can now
+ inspect stack traces reaching into the machine-dependent bits
+ implemented in assembler.
+ As usual, bugs have been fixed throughout the code, including minor
+ issues with the gsync synchronization mechanism which is now used for
+ the internal locks in the GNU C Library (glibc).
+ The deprecated external memory management interface has been removed.
+ The partial ACPI support has been removed.

+ [[**GNU Mach**|microkernel/mach/gnumach]] is the GNU distribution of the
+ [[Mach microkernel|microkernel/mach]], upon which a GNU Hurd system is
+ based. The [[microkernel]] provides an [[Inter Process Communication
+ (IPC)|ipc]] mechanism that the Hurd uses to define interfaces for
+ implementing in a distributed multi-server fashion the services a
+ traditional operating system kernel provides. More detailed:
+ [[microkernel/mach/documentation]].
+ * **GNU MIG 1.8**,
+ [NEWS](
+ Version 1.8 (2016-12-18)

+ [[**GNU MIG**|microkernel/mach/mig/gnu_mig]] is the GNU distribution of the
+ [[Mach 3.0 Interface Generator (MIG)|microkernel/mach/mig]]. This tool
+ translates [[Remote Procedure Call (RPC)|rpc]] definition files to C code,
+ and is required to compile any packages that are receiving or invoking
+ RPCs, such as GNU Mach, GNU Hurd, and the GNU C Library (glibc) when
+ compiled for the Hurd. More detailed:
+ [[microkernel/mach/mig/documentation]].
+ * **glibc-2.23-hurd+libpthread-20161218**
+ Based on the [[glibc]] 2.23 release, we include additional changes for GNU
+ Hurd support, and bundle GNU Hurd's [[libpthread]].

+ The [[**GNU C Library** (glibc)|glibc]] implements a system's standard
+ library functions (as described by ISO C, and POSIX, for example). An
+ important part of the Hurd actually resides in glibc: here, the system
+ interfaces are implemented on top of the [[Hurd IPC
+ protocols|hurd/interface]]. This is different to the Linux port, where
+ most simple system interfaces are in fact simply forwarded to/implemented
+ as [[system_call]]s.
+Many thanks to all the people who are helping!
+If you want to give the Hurd a try, you may easily do so with [[Debian
+The GNU Hurd system currently runs on 32-bit x86 machines. To compile the
+Hurd, you need a toolchain configured to target `i?86-gnu`; you cannot use a
+toolchain targeting GNU/Linux.
