+        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

+    traditional operating system kernel provides.  More detailed:

+          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.

+
+    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
