We're pleased to announce new releases!
* **GNU Hurd 0.9**,
[NEWS](http://git.savannah.gnu.org/cgit/hurd/hurd.git/tree/NEWS?id=v0.9):
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).

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](http://git.savannah.gnu.org/cgit/hurd/gnumach.git/tree/NEWS?id=v1.8):
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](http://git.savannah.gnu.org/cgit/hurd/mig.git/tree/NEWS?id=v1.8):
Version 1.8 (2016-12-18)
A spurious warning in the generated code has been fixed.

[[**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
GNU/Hurd|hurd/running/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.
Please read the [[FAQ]].
