Besides that, it introduces SAUL, +the [S]ensor [A]ctuator [U]ber [L]ayer, which offers a unified API to interact with all +different types of sensors and actuators on RIOT supported hardware. Furthermore, it re-enables +the support for ICN by integrating CCN-Lite as a package. A lot of new overall documentation was +added and existing documentation was improved (http://riot-os.org/api/). In addition, +a Vagrant (https://www.vagrantup.com/) configuration file was added to the RIOT repository in +order to create reproducible and portable environments that contain all necessary toolchains. + +About 222 pull requests with about 631 commits have been merged since the last release and 48 +additional issues have been solved. 37 people contributed code in 102 days. 980 files have been +touched with ~59779 insertions and ~12115 deletions. + +Notations used below: +===================== ++ means new feature/item +* means modified feature/item +- means removed feature/item + + +New features and changes +======================== + +General +------- + +Device support +-------------- ++ SAUL [S]ensor [A]ctuator [U]ber [L]ayer + +Core +---- +* replaced deprecated dINT()/eINT() calls by up-to-date disableIRQ()/enableIRQ()/restoreIRQ() + calls throughout the whole core + +Network Stack +------------- ++ TFTP support ++ 6LoWPAN: Next Header Compression ++ leaf mode for RPL nodes +* RPL: refactoring of instances and dodags (saved 1kB ROM and 0,5kB RAM) +* FIB: initial source route support +* change to non-blocking 6LoWPAN fragmentation +* POSIX sockets: various fixes +* periodic stats printing for ping6 command +* convert all vtimer into xtimer calls +* send router advertisements without PIOs + +Packages +-------- ++ CCN-Lite as a ICN network stack ++ RELIC: efficient cryptography library +* fix TLSF to compile with -pedantic + +Supported platforms +------------------- +Additional support for the following boards: ++ weio board with NXP LPC11U34 (ARM Cortex-M0) ++ Silicon Labs Wireless Eval Kit SLWSTK6220A (Wonder Gecko) ++ STM32 Nucleo-F401 + +Drivers +------- ++ Arduino-mega2560 GPIO ++ Arduino pin mapping for Mega2560 and Due + +Network drivers +--------------- ++ enc28j60 Ethernet chip ++ at86rf2xx: Add support for channel page +* at86rf2xx: fix LQI reading +* implement sleep mode for at86rf2xx + +Sensors drivers +--------------- ++ AT30TSE75x temperature sensor ++ TCS3772 Color Light-to-Digital converter + +System libraries +---------------- ++ partial support for the Arduino API ++ lightweight semaphores ++ fmt: simple string formatting library ++ xtimer: 32-bit version of msg_recv_timeout +* implicit socket binding for POSIX connect() and sendto() +* posix_semaphore: make API POSIX compliant + +Examples +-------- ++ microcoap/conn example ++ minimal GNRC networking example + +Build System +------------ +* split the Cortex-M0 buildtest group to avoid timeout issues with Travis +* split the Cortex-M4 buildtest group to avoid timeout issues with Travis + +Other +----- ++ vagrant configuration ++ documentation: various high-level descriptions of crucial features ++ IoT-LAB: create and connect to debug server +* pyterm: fix problems with German umlauts as input + +Fixed Issues from the last release +================================== + +#2724: Add support for serial number passing to CMSIS boards, document it + Documentation about how to discover and set the serial number of CMSIS-DAP chips is missing +#3201: Odd length packet snips cause invalid check sum + If an odd length packet snip occurs in a packet and is not the last snip + (in the order the packet is supposed to be, not in the list's order) + in a packet it will generate a wrong check sum. + +Known Issues +============ + +network related issues +---------------------- +#3075: nhdp: unnecessary microsecond precision + NHDP works with timer values of microsecond precision which is not required.
