RIOT-2018.10 - Release Notes
============================
RIOT is a multi-threading operating system which enables soft real-time
capabilities and comes with support for a range of devices that are typically
found in the Internet of Things: 8-bit and 16-bit microcontrollers as well as
light-weight 32-bit processors.
RIOT is based on the following design principles: energy-efficiency, soft
real-time capabilities, small memory footprint, modularity, and uniform API
access, independent of the underlying hardware (with 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:
===================
The 2018.10 release includes new features, like CoAP Resource Directory and
Block2, ESP32 support, rework of I2C interface, EEPROM registry,
Full and Minimal Thread Devices support in OpenThread and compliance of
LoRaWAN 1.0.2 (ABP counters stored in EEPROM). Several boards were introduced.
During the last release the board documentation was migrated from the wiki to
the [RIOT API documentation](https://doc.riot-os.org) to improve the
maintenance of these entries and provide a better user experience when
browsing the documentation. There were also some efforts in grouping some
modules to make them easier to access in the documentation.
There were also some efforts on refactoring, test improvements and bug fixes.
About 392 pull requests with about 914 commits have been merged since the last
release and about 20 issues have been solved. 57 people contributed with code
in 100 days. Approximately 2184 files have been touched with 211964 insertions
and 34806 deletions.

RIOT-2018.07 - Release Notes
============================
RIOT is a multi-threading operating system which enables soft real-time
capabilities and comes with support for a range of devices that are typically
found in the Internet of Things: 8-bit and 16-bit microcontrollers as well as
light-weight 32-bit processors.
RIOT is based on the following design principles: energy-efficiency, soft
real-time capabilities, small memory footprint, modularity, and uniform API
access, independent of the underlying hardware (with 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:
===================
The 2018.07 release includes new features, like NimBLE (ble stack),
a MQTT-SN client, SHA-1 based PRNG, an UUID implementation. The RISC-V CPU
architecture support used by the hifive1 board.
Effort was done on refactoring, documentation, test improvements and bug fixes.
During the last release, maintainers contributed by running the automated test
suites on their boards. This gave valuable feedback on the board support state,
test reliability and where to focus effort to make testing easier and more
reliable.
About 380 pull requests with about 675 commits have been merged since the last
release and about 27 issues have been solved. 45 people contributed with code
in 93 days. Approximately 1678 files have been touched with 147122 insertions
and 16060 deletions.

About this release:
===================
The 2018.04 release includes major progress in support for current crypto
libraries. A lot of work has gone into updating drivers to RIOT's unified
configuration scheme. Support for ten new boards has been added. In our quest
to improve and automate testing, many test scripts have been fixed and
improved, and RIOT's CI now runs many tests on real hardware during its nightly
build testing. And as usual, many tiny fixes and improvements have been merged.
About 390 pull requests with about 1073 commits have been merged since the last
release and about 54 issues have been solved. 44 people contributed with code
in 98 days. Approximately 1491 files have been touched with 208426 insertions.

RIOT-2018.01 - Release Notes
============================
RIOT is a multi-threading operating system which enables soft real-time
capabilities and comes with support for a range of devices that are typically
found in the Internet of Things: 8-bit and 16-bit microcontrollers as well as
light-weight 32-bit processors.
RIOT is based on the following design principles: energy-efficiency, soft
real-time capabilities, small memory footprint, modularity, and uniform API
access, independent of the underlying hardware (with partial POSIX compliance).
RIOT is developed by an international open-source community which 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:
===================
The 2018.01 release includes major progress in RIOTs network communication
capabilities, i.e., rewrite of GNRC's neighbour discovery, confirmable messages
in (g)CoAP, LoRa, and GoMacH as well as updates on CCN-lite and LWIP.
Furthermore, RIOT contributes to _IKEA-Hacking_ by bringing support for
the smart home lighting system TRADFRI (note: this will void the warranty).
Needless to say that this release also adds and updates support for several
platforms, drivers, and of course lots of enhancements to the documentation
as well as numerous bug fixes. Last but not least, RIOT now has an official
code of conduct (https://github.com/RIOT-OS/RIOT/blob/master/CODE_OF_CONDUCT.md)
More than 442 pull requests with about 865 commits have been merged since the

Fixed Issues from the last release (2017.10)
============================================
#2143: unittests: tests-core doesn't compile for all platforms
#4499: handle of l2src_len in gnrc_ndp_rtr_sol_handle
#4822: kw2xrf: packet loss when packets get fragmented
#5005: ndp: router advertisement sent with global address
#5122: NDP: global unicast address on non-6LBR nodes disappears after a while
#5656: Possible Weakness with locking in the GNRC network stack
#5790: ND: Lost of Global IPV6 on node after sending lot of UDP frame from BR

Known Issues
============
Networking related issues
-------------------------
#5230: gnrc ipv6: multicast packets are not dispatched to the upper layers
#5858: gnrc: 6lo: potential problem with reassembly of fragments: If one frame
gets lost the reassembly state machine might get out of sync
#7035: lwIP: hangs due to sema change after a while
Timer related issues
--------------------
#5103: xtimer: weird behavior of tests/xtimer_drift: xtimer_drift randomly
jumps a few seconds on nrf52
#5338: xtimer: xtimer_now() not ISR safe for non-32-bit platforms.
#6052: tests: xtimer_drift gets stuck: application freezes after ~30-200 seconds
#7114: xtimer: add's items to the wrong list if the timer overflows between
_xtimer_now() and irq_disable()
native related issues
---------------------
#495: native not float safe: When FPU is used and an asynchronous context
switch occurs, either the stack gets corrupted or a floating point
exception occurs.
#6442: cpu/native: timer interrupt does not yield thread
other platform related issues
-----------------------------
#1891: newlib-nano: Printf formatting does not work properly for some numeric
types: PRI[uxdi]64, PRI[uxdi]8 and float are not parsed in newlib-nano
#4866: not all GPIO driver implementations are thread safe: Due to non-atomic
operations in the drivers some pin configurations might get lost.
#5848: Arduino: Race condition in sys/arduino/Makefile.include
#6018: nRF52 gnrc 6lowpan ble memory leak
#6261: SAMD21: TC3 & TC4 issue when using TCC2
#6379: nrf52dk/nordic_soft_device: not working anymore
#6437: periph/spi: Leftovers from SPI rework
#6526: atmega based boards freeze when main thread is over
#6836: Issuing a reboot on ATmega328p makes the board loop-reboot
#7753: pic32-wifire: race-condition when linking in concurrent build
other issues
------------
#1263: TLSF implementation contains (a) read-before-write error(s).
#3366: periph/i2c: handle NACK
#4488: Making the newlib thread-safe: When calling puts/printf after
thread_create(), the CPU hangs for DMA enabled UART drivers.
#5776: make: Predefining CFLAGS are parsed weirdly
#5863: OSX + SAMR21-xpro: shell cannot handle inputs of length >64 chars
#5962: Makefile: UNDEF variable is not working as documented
Acknowledgements
================
We would like to thank all companies (vendors) that provided us with (their)
hardware for porting and testing RIOT-OS. Further thanks go to companies and
institutions that directly sponsored development time. And finally, big thanks
to all of you contributing in so many different ways to make RIOT worthwhile!
