+RIOT-2014.01 - 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).
+
+New features
+============
+Core
+----
++ msg_receive() with timeout
++ LPM support for MSP430 based platforms
++ introduced a version string
+
+Supported platforms
+-------------------
+Additional support for the following boards:
++ TelosB
++ mbed LPC1768
+
+Sensor drivers
+---------------
++ drivers for the LM75A Digital temperature sensor and thermal watchdog
++ SRF02 and SRF08 ultrasonic range finders
+
+Native port
+-----------
++ implemented UART via I/O redirection or TCP and UNIX socket
+
+System libraries
+----------------
++ Mersenne twister pseudorandom number generator
++ crypto libraries
+  + 3des
+  + aes
+  + rc5
+  + skipjack
+  + twofish
++ BSD-like package system for easy integration of external libraries
+
+Network stack
+-------------
++ port of CCN lite
++ POSIX socket wrapper
++ integration of libcoap
++ integration of OpenWSN
+
+Further Changes
+===============
+* boards and projects repositories have been integrated and are now part of
+  the RIOT repository itself
+* full refactoring of the network stack and introducing a substructure
+  according to the modules' functionalities
+* cleaned up Makefile system and simplified binary folder
+* more documentation
+* various bug fixes and cleanups
+
+Fixed Issues from the last release
+==================================
+#83: Wrong byte order in sixlowpan
+    To our best knowledge all occurrences of wrong byte order within the 6LoWPAN
+    network stack are fixed now.
+#132: segfault in vtimer update shortterm
+    The vtimer has been carefully evaluated and all known issues concerning this
+    module are fixed.
+
+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.
+#82: Setting STATUS_REPLY_BLOCKED thread to STATUS_PENDING though it is not
+     handled yet
+    In some rare cases the status of a thread might falsely change to
+    STATUS_PENDING instead of STATUS_REPLY_BLOCKED.
+#426: Interrupt handling on MSP430 is buggy
+    UART and timer handling is currently unstable on MSP430 based platforms
+#455: sha256 is broken on MSP430
+    For unknown reasons sha256 calculates wrong results on MSP430 based platforms.
+#495: native not float safe
+    When the FPU is used when an asynchronous context switch occurs, either the
+    stack gets corrupted or a floating point exception occurs.
+#498: native is segfaulting at startup
+    In some cases (about 5-10%) a RIOT native process crashes with a SEGFAULT
+    at startup.
+#499: native is segfaulting on heavy network usage
+    Sending more than 100 packets per second causes a SEGFAULT in RIOT native.
+#505: native on FreeBSD is broken
+    Due to different parameter handling in FreeBSD, native is currently not
+    working there.
