News items:
- For details, see Richards report about running
[Hurd without dependency on cthreads](http://lists.gnu.org/archive/html/bug-hurd/2012-08/msg00062.html).
- new cd images with keyboard layout configuration http://lists.gnu.org/archive/html/bug-hurd/2012-07/msg00048.html
- Pino Toscano: FIFO sockets with mknod (test passes now) http://lists.gnu.org/archive/html/bug-hurd/2012-09/msg00053.html
- Pino Toscano added a size parameter to tmpfs for easier usage in scripts: http://lists.gnu.org/archive/html/bug-hurd/2012-09/msg00005.html and a [version suffix option](http://lists.gnu.org/archive/html/bug-hurd/2012-10/msg00009.html) for gnumach configure.
- Pino Toscano added patches for [procfs](http://lists.gnu.org/archive/html/bug-hurd/2012-09/msg00004.html), [ptrace](http://lists.gnu.org/archive/html/bug-hurd/2012-10/msg00035.html), [fsync on stdout](http://lists.gnu.org/archive/html/bug-hurd/2012-10/msg00046.html), [muntrace](http://lists.gnu.org/archive/html/bug-hurd/2012-11/msg00033.html), [ulimit](http://lists.gnu.org/archive/html/bug-hurd/2012-11/msg00034.html), [glibc](http://lists.gnu.org/archive/html/bug-hurd/2012-11/msg00029.html) which among others improve POSIX conformance, making it easier to write programs which work on the Hurd and GNU/Linux.
- Cyril Roeland fixed a documentation typo [in ps](http://lists.gnu.org/archive/html/bug-hurd/2012-10/msg00032.html) and a missing linker flag [in procfs](http://lists.gnu.org/archive/html/bug-hurd/2012-10/msg00025.html).
- Samuel Thibault pushed the [pthread patches](http://lists.gnu.org/archive/html/bug-hurd/2012-11/msg00088.html) from Vincente, Barry, Thomas, Richard and Samuel and others to the different upstream packages, finally enabling modern pthreads for the Hurd, which makes it possible to implement full Hurd bindings for languages which require pthreads, so for example [PyHurd](http://savannah.nongnu.org/projects/pyhurd/) can profit from the Hurd libraries instead of having to rely on low-level Mach bindings to implement Hurd features.
- Thomas Schwinge fixed [some errors](http://lists.gnu.org/archive/html/bug-hurd/2012-11/msg00077.html) which caused a miscalculation of the size of medium sized disks reporting 15 heads instead of 16.
- Svante Signell [improved](http://lists.gnu.org/archive/html/bug-hurd/2012-11/msg00062.html) the error handling in pflocal,
- Pino Toscano [implemented syncfs](http://lists.gnu.org/archive/html/bug-hurd/2012-11/msg00046.html) which ensures that all data in the filesystem gets written to disk, as well as [statfs](http://lists.gnu.org/archive/html/bug-hurd/2012-12/msg00005.html), which adds some additional statistics to procfs.
- Matthew Leach [fixed](http://lists.gnu.org/archive/html/bug-hurd/2012-11/msg00037.html) a compilation error with older GCC versions due to duplicate type definition.
- Samuel Thibault [provided](http://lists.gnu.org/archive/html/bug-hurd/2012-12/msg00052.html) new [installation CDs](http://people.debian.org/~sthibault/hurd-i386/installer/cdimage/current) and a new [qemu image](http://people.debian.org/~sthibault/hurd-i386/).
- Thomas Schwinge [debugged and fixed](http://lists.gnu.org/archive/html/bug-hurd/2012-12/msg00044.html) a deadlock with child threads resulting from a regression due to earlier fixes.
- Cyril Roelandt shared a [patch series](http://lists.gnu.org/archive/html/bug-hurd/2012-12/msg00018.html) to fix double mutex unlocking with pthreads. We will likely see more fixes like these, given that the whole threading interface changed.
- Cyril Roelandt fixed a [ps](http://lists.gnu.org/archive/html/bug-hurd/2012-12/msg00012.html) bug.

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|hurd/documentation]].
**GNU Mach** is the microkernel upon which a GNU Hurd system is based. It
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|microkernel/mach/gnumach]].
