| GNU Hurd 0.8, GNU Mach 1.7, GNU MIG 1.7 released.
| We're pleased to announce new releases!
|     GNU Hurd 0.8, NEWS:
|     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 
|     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 is the GNU project's replacement for the Unix kernel. It is 
a collection of servers 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: documentation, what is the GNU Hurd.
|     GNU Mach 1.7, NEWS:
|     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 
|     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 
|     futexes, to allow efficient and powerful userland synchronization.
|     Support for profiling kernel code from userland through sampling was

|     GNU Mach is the GNU distribution of the Mach microkernel, upon which a 
GNU Hurd system is based. The microkernel provides an Inter Process 
Communication (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: documentation.
|     GNU MIG 1.7, NEWS:
|     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 is the GNU distribution of the Mach 3.0 Interface Generator 
(MIG). This tool translates Remote Procedure Call (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: 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) 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. This is different to the Linux port, where 
most simple system interfaces are in fact simply forwarded to/implemented as 
system calls.
| 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.
| 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 bug-hurd or filed on 
http://savannah.gnu.org/bugs/?group=hurd. Requests for assistance should be 
sent to 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 channel.
