RIOT-2016.04 - 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: 8-bit microcontrollers, 16-bit microcontrollers and 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 is developed by an international open source community which is independent of specific vendors (e.g. similarly to the Linux community) and is licensed with a non-viral copyleft license (LGPLv2.1), which allows indirect business models around the free open-source software platform provided by RIOT. About this release: =================== This release adds support for two additional network stacks: lwIP and emb6. A bunch of additional protocols are now available, P2P-RPL in the GNRC network stack, Ethernet-over-Serial (ethos). Murdock, the new, blazing fast RIOT CI is now available to significantly speed up code merging procedures. This release also adds support for a number of new boards and sensors and a new tool for automated border router setup is now provided which greatly simplifies that setup for newbies as well as for old-timers. Last but not least: this release includes a number of bug fixes, mostly about stabilizing and enhancing the networking capabilities of RIOT. About 470 pull requests with about 1196 commits have been merged since the last release and 127 additional issues have been solved. 55 people contributed code in 124 days. 1521 files have been touched with ~91700 insertions and ~42200 deletions. Notations used below: ===================== + means new feature/item * means modified feature/item - means removed feature/item New features and changes ======================== General ---------- + added Makefile support for creating a "binary distribution", making it easier to create closed source applications while still complying to LGPL Testing

The friendly Operating System for IoT!
FEATURES
RIOT OS is an operating system for Internet of Things (IoT) devices. It is based on a microkernel and designed for
- energy efficiency
- hardware independent development
- a high degree of modularity
Its features comprise
- a preemptive, tickless scheduler with priorities
- flexible memory management
- high resolution, long-term timers
- support for AVR, MSP430, ARM7, and ARM Cortex-M on over 50 boards
- the native port allows to run RIOT as-is on Linux, BSD, and MacOS. Multiple instances of RIOT running on a single machine can also be interconnected via a simple virtual Ethernet bridge
- IPv6
- 6LoWPAN (RFC4944, RFC6282, and RFC6775)
- UDP
- RPL (storing mode)
- CoAP
- CCN-Lite
GETTING STARTED
- You want to start the RIOT? Just follow our Getting started documentation
- The RIOT API itself can be built from the code using doxygen. The latest version is uploaded daily to http://riot-os.org/api.
USING THE NATIVE PORT WITH NETWORKING
If you compile RIOT for the native cpu and include the netdev2_tap module, you can specify a network interface like this: PORT=tap0 make term
SETTING UP A TAP NETWORK
There is a shellscript in RIOT/dist/tools/tapsetup called tapsetup which you can use to create a network of tap interfaces.
USAGE To create a bridge and two (or count at your option) tap interfaces:
./dist/tools/tapsetup/tapsetup [-c [<count>]]
CONTRIBUTE
To contribute something to RIOT, please refer to the development procedures and read all notes for best practice.
