+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
+compliance).
+
+RIOT leverages a robust micro-kernel architecture based on the FeuerWare kernel
+originally developed in 2008 targeting Wireless Sensor Networks, and further
+developed in µkleos. As such, RIOT is the direct heir of FeuerWare and µkleos.
+
+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.

+Known Issues
+============
+#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
+    without stdin.
+#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
+    transceivers.
+#83: Wrong byte order in sixlowpan
+    The 6LoWPAN stack might still contain some variables using the wrong byte
+    order.
+#132: segfault in vtimer update shortterm
+    The vtimer is known to be buggy on all platforms and causes segmentation
+    faults on the native port.
