We're pleased to announce new releases!
* **GNU Hurd 0.8**,
[NEWS](http://git.savannah.gnu.org/cgit/hurd/hurd.git/tree/NEWS?id=v0.8):
Version 0.8 (2016-05-18)
The netfs library is using the lockless reference-counting primitives
for both peropen and node objects now, and the global reference
counting lock has been removed.
The integer hashing library gained a new interface to use non-integer
keys. It is now used in libdiskfs' and nfs' node cache, and the ftpfs
translator.
Several bugs in our native fakeroot tool have been fixed improving
stability and correctness of the translation.
The devnode translator and the hurd-slab library have been merged into this
repository.
The code has been cleaned up, and we fixed numerous bugs, most notably
a crash in pfinet, a locking bug in libdiskfs, and an out-of-bounds
access in ext2fs' block cache.

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 1.7**,
[NEWS](http://git.savannah.gnu.org/cgit/hurd/gnumach.git/tree/NEWS?id=v1.7):
Version 1.7 (2016-05-18)
The code has been updated to work with newer versions of GCC, and numerous bugs
have been fixed throughout the code, including a pageout deadlock. The code
uses integer types from <stdint.h> now instead of the old Mach types.
The VM cache policy change has been merged. The kernel now caches
unreferenced VM objects unconditionally instead of using a fixed
limit.
The physical page allocator of the X15 kernel has been integrated, and
is now used directly by the slab allocator. This increases the kernel
heap addressing important scalability issues.
The gsync synchronization mechanism was added, similar to the Linux kernel's
futexes, to allow efficient and powerful userland synchronization.
Support for profiling kernel code from userland through sampling was added.

[[**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 1.7**,
[NEWS](http://git.savannah.gnu.org/cgit/hurd/mig.git/tree/NEWS?id=v1.7):
Version 1.7 (2016-05-18)
* MIG now has a test suite. It includes a set of valid and invalid
definition files that MIG will try to process. For valid
definitions, GCC will compile the stubs to check if valid C code was
generated.
* The generated code uses integer types from <stdint.h> now instead of
the old Mach types.
* Code that was hard-coding the word size has been identified and
fixed.
* Support for the obsolete kinds of RPC routines 'functions',
'procedures', and 'simple procedures' has been removed.
* MIG now emits code that casts objects translated from capabilities
to the correct C type.

[[**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-2.19-hurd+libpthread-20160518**
Based on the [[glibc]] 2.19 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]].
Bug reports should be sent to [[mailing_lists/bug-hurd]] or filed on
<http://savannah.gnu.org/bugs/?group=hurd>. Requests for assistance
should be sent to [[mailing_lists/help-hurd]] or filed on
<http://savannah.gnu.org/support/?group=hurd>. You can also find us on
the Freenode IRC network in the [[#hurd|IRC]] channel.
