RIOT-2017.07 - 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 microcontrollers, 16-bit
microcontrollers and 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:
===================
This release provides fixes, code cleanup and improved documentation, as well as
enhancements.
New features brought by this release include:
* CAN support (Controller Area Network)
* Support for CoAP OBSERVE requests
* Basic Thread stack support (initial support for OpenThread)
* radio duty cycling with LwMAC protocol
* LoRa radio drivers supporting Semtech hardware
About 230 pull requests with about 442 commits have been merged since the last

About this release:
===================
This release provides a lot of new features, fixes and enhancements. Among
these has been a huge cleanup regarding cppcheck and documentation, and we're
pleased to announce that all remaining doxygen and cppcheck warnings have been
fixed. We're also proud to present a Virtual File System layer and integration
of the SPIFFS file system. A lot of work has gone into support for
STMicroelectronics's Nucleo family, with RIOT now supporting 28 (up from 13)
Nucleo boards. And as always, there was a lot of under-the-hood cleanup, bug
fixing and documentation work.
About 200 pull requests with about 562 commits have been merged since the last release and about 23
issues have been solved. 32 people contributed with code in 91 days. 2697 files have been touched with
716950 insertions and 492623 deletions.

RIOT-2017.01 - 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 microcontrollers,
16-bit microcontrollers and 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:
===================
This release provides a lot of new features, fixes and enhancements. Among others these features
contain an initial - still experimental - TCP implementation based on the GNRC network stack, support
for reading from and writing to SD cards, a new power management architecture as well additional third
party packages such as TweetNaCl, a cryptographic library, and Heatshrink a data compression library
optimized for embedded real-time systems.
We added support for new platforms including the Calliope mini, Maple mini, and a couple of STMs
Nucleo boards. Device support was extended by several new drivers, e.g., for NXP PN532 NFC, Microchip
MRF24J40 802.15.4 radio (experimental), or Bosch BME280 pressure/humidity/temperature sensor.
We completely refactored the SPI interface, allowing for internally handled hardware or software chip
select lines and shared bus usage for multiple devices with different SPI configurations.
About 278 pull requests with about 606 commits have been merged since the last release and about 84
issues have been solved. 44 people contributed with code in 87 days. 2230 files have been touched with
220275 insertions and 159840 deletions.

Fixed Issues from the last release
==================================
#4388: POSIX sockets: open socket is bound to a specific thread
#4737: cortex-m: Hard fault after a thread exits
#4874: Using single RSSI_BASE_VALUE for all Atmel radios
#5034: gnrc_networking: offers txtsnd, does not print received packets
#5083: AVR8: Reboots after `return 0;`
#5719: cc2538: rf driver doesn't handle large packets
#5954: nRF52 uart_write gets stuck
#6036: tinydtls: DTLS randomly missing functions
#6037: pkg/nanocoap: native build fails on macOS
#6358: arduino uno : xtimer accuracy problem
Known Issues
============
Networking related issues
-------------------------
#3075: nhdp: unnecessary microsecond precision: NHDP works with timer values of microsecond precision
which is not required. Changing to lower precision would save some memory.
#4048: potential racey memory leak: According to the packet buffer stats, flood-pinging a multicast
destination may lead to a memory leak due to a race condition. However, it seems to be a rare
case and a completely filled up packet buffer was not observed.
#5016: gnrc_rpl: Rejoining RPL instance as root after reboot messes up routing
#5230: gnrc ipv6: multicast packets are not dispatched to the upper layers
#5656: Possible Weakness with locking in the GNRC network stack: For some operations mutexes to the
network interfaces need to get unlocked in the current implementation to not get deadlocked.
Recursive mutexes as provided in #5731 might help to solve this problem.
#5748: gnrc: nodes crashing with too small packet buffer: A packet buffer of size ~512 B might lead
to crashes. The issue describes this for several hundret nodes, but agressive flooding with
just two nodes was also shown to lead to this problem.
#5858: gnrc: 6lo: potential problem with reassembly of fragments: If one frame gets lost the reassembly
state machine might get out of sync
#6123: gnrc: crash with (excessive) traffic
NDP is not working properly
---------------------------
#4499: handle of l2src_len in gnrc_ndp_rtr_sol_handle: Reception of a router solicitation might lead
to invalid zero-length link-layer addresses in neighbor cache.
#5005: ndp: router advertisement sent with global address: Under some circumstances a router might
send RAs with GUAs. While they are ignored on receive (as RFC-4861 specifies), RAs should have
link-local addresses and not even be send out this way.
#5122: NDP: global unicast address on non-6LBR nodes disappears after a while: Several issues
(also see #5760) lead to a global unicast address effectively being banned from the network
(disappears from neighbor cache, is not added again)
#5467: ipv6 address vanishes when ARO (wrongly) indicates DUP caused by outdated ncache at router
#5539: Border Router: packet not forwarded from ethos to interface 6
#5790: ND: Lost of Global IPV6 on node after sending lot of UDP frame from BR
Timer related issues
--------------------
#4841: xtimer: timer already in the list: Under some conditions an xtimer can end up twice in the
internal list of the xtimer module
#4902: xtimer: xtimer_set: xtimer_set does not handle integer overflows well
#5338: xtimer: xtimer_now() not ISR safe for non-32-bit platforms.
#5928: xtimer: usage in board_init() crashes: some boards use the xtimer in there board_init()
function. The xtimer is however first initialized in the auto_init module which is executed
after board_init()
#6052: tests: xtimer_drift gets stuck: xtimer_drift application freezes after ~30-200 seconds
#6331: RTC alarm triggered with 1s delay
#6419: cpu/cc2538: timer broken
#6427: xtimer: infinite loop with xtimer_mutex_lock_timeout
#6502: cpu/stm32l1: RTC broken
#6542: boards/nucle-f0xx: misconfigured timer configuration (fix in #6494)
native related issues
---------------------
#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.
#2175: ubjson: valgind registers "Invalid write of size 4" in unittests
#4590: pkg: building relic with clang fails.
#5796: native: tlsf: early malloc will lead to a crash: TLSF needs pools to be initialized (which is
currently expected to be done in an application). If a malloc is needed before an application's
main started (e.g. driver initialization) the node can crash, since no pool is allocated yet.
#6145: native: system reboots on SIGTRAP
#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
#2006: cpu/nrf51822: timer callback may be fired too early

unittests which are not available with msp430-gcc
#2300: qemu unittest fails because of a page fault
#4512: pkg: tests: RELIC unittests fail on iotlab-m3
#4560: make: clang is more pedantic than gcc oonf_api is not building with clang (partly fixed by #4593)
#4694: drivers/lm75a: does not build
#4822: kw2xrf: packet loss when packets get fragmented
#4876: at86rf2xx: Simultaneous use of different transceiver types is not supported
#4954: chronos: compiling with -O0 breaks
#4866: not all GPIO driver implementations are thread safe: Due to non-atomic operations in the drivers
some pin configurations might get lost.
#5009: RIOT is saw-toothing in energy consumption (even when idling)
#5103: xtimer: weird behavior of tests/xtimer_drift: xtimer_drift randomly jumps a few seconds on nrf52
#5361: cpu/cc26x0: timer broken

About this release:
===================
This release provides a lot of new features as well as it fixes several major
bugs. Among these new features are the new simplified network socket API
called sock, the GNRC specific CoAP implementation gcoap and several new
packages: TinyDTLS, the Aversive++ microcontroller library for robotics, the
u8g2 graphic library, and nanocoap.
Using the new sock API an implementation of the Simple Time Network Protocol
(SNTP) was also introduced, allowing for time synchronization between nodes.
New platforms include the Arduino Uno, the Arduino Duemilanove, the Arduino
Zero, SODAQ Autonomo, and the Zolertia remote (rev. B).
The most significant bug fix was done in native which led to a significantly
more robust handling of ISRs and now allows for at least 1,000 native
instances running stably on one machine.
About 263 pull requests with about 398 commits have been merged since the last
release and about 42 issues have been solved. 37 people contributed with code
in 100 days. 1006 files have been touched with 166500 insertions and 26926
deletions.

Fixed Issues from the last release
==================================
#3824: native: gnrc: hardcore pinging crashes.
#4583: cpp11: clang doesn't allow mutex_t to be used with constexpr All
cpp11-* tests fail with clang.
#5388: gnrc_sixlowpan_iphc_nhc: receiving NHC compressed UDP
packets hits assert in IPv6 (Fixed by #5281).
Known Issues
==========
#3075: nhdp: unnecessary microsecond precision NHDP works with timer
values of microsecond precision which is not required. Changing to lower
precision would save some memory.
#3086: Max. packet length for AT86RF2XX
#4048: potential racey memory leak According to the packet buffer stats,
flood-pinging a multicast destination may lead to a memory leak due to a
race condition. However, it seems to be a rare case and a completely filled
up packet buffer was not observed.
#5005: ndp: router advertisement sent with global address Under some
circumstances a router might send RAs with GUAs. While they are ignored
on receive (as RFC 4861 specifies), RAs should have link-local addresses
and not even be send out this way.
#5007: gnrc icmpv6: Ping reply goes out the wrong interface
#5055: cpuid: multiple radios will get same EUI-64 Nodes with multiple
interfaces might get the same EUI-64 for them since they are generated from
the same CPU ID.
#5230: gnrc ipv6: multicast packets are not dispatched to the upper layers.
(Fix exists, but was postponed)
#5390: pkg: OpenWSN does not compile This package still uses deprecated
modules and was not tested for a long time.
native related issues
---------------------
#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.
#534: native debugging on osx fails Using valgrind or gdb with a nativenet
target in OSX leads to "the network" being stuck (gdb) or the whole process
being stuck (valgrind).
