Dear RIOT developers and users,
we proudly announce the first official release of the RIOT operating system:
* RIOT 2013.08 *
This release version comprises the results of the development on the
microkernel and userspace libraries during the last four years as well as more
recent activities on IoT protocols (e.g. 6LoWPAN or RPL).
Since the number of supported hardware for RIOT is constantly increasing, this
release already provides support for various ARM and MSP430 microcontrollers,
miscellaneous radio transceivers, and sensor devices. We furthermore included
the native port and native networking to enable testing, debugging, and
developing RIOT applications easily on your Linux or Mac computer. Finally, we
incorporated the valuable experience that we gathered recently during the ETSI
plugtest event on 6LoWPAN .
Read more about all features in our release notes (attached) or in RIOT's
README . New users should also look at the Getting Started tutorial .
You can download the RIOT release from Github, either by cloning the
repositories or using the tarballs:

RIOT-2013.08 - Release Notes
RIOT is a real-time multi-threading operating system that supports a range of
devices that are typically found in the Internet of Things: from 16-bit
microcontrollers to light-weight 32-bit processors.
RIOT is based on the following design principles: energy-efficiency, real-time
capabilities, small memory footprint, modularity, and uniform API access,
independent of the underlying hardware (this API offers partial POSIX
RIOT leverages a robust micro-kernel architecture based on the FeuerWare kernel
originally developed in 2008 targeting Wireless Sensor Networks, and further
developed in ?kleos. As such, RIOT is the direct heir of FeuerWare and ?kleos.
To lower the hurdles for new developers, all coding in RIOT can be done in
standard C (or C++) with standard tools like gcc and gdb, which also
facilitates application development and adaptation of existing Linux libraries.
Last but not least: the native port allows to run RIOT as-is on Linux and
MacOS. Multiple instances of RIOT running on a single machine can also be
interconnected via a simple virtual Ethernet bridge, which facilitates
networked application development.

#21: Deal with stdin in bordermultiplex.c
Not all supported platforms provide a stdin in the current release.
However, the implementation of the 6LoWPAN border router won't work
#45: bit field order in the fcf may be wrong
The CC2420 FIFO expects the IEEE802.15.4 FCF field in reversed bit order.
This might break the implementation for other, upcoming radio
#83: Wrong byte order in sixlowpan
The 6LoWPAN stack might still contain some variables using the wrong byte
#132: segfault in vtimer update shortterm
The vtimer is known to be buggy on all platforms and causes segmentation
faults on the native port.
