Release-2019.10

RIOT-2019.10 - 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 2019.10 release includes:

initial support for SUIT firmware updates
USB CDC-ACM serial communication
complete rewrite of TI CC110x radio driver
initial support for IPv6 fragmentation
DTLS support in the sock networking stack
complete blockwise messaging for gcoap and nanocoap
as always, bug fixes and documentation updates

About 460 pull requests, composed of 950 commits, have been merged since the
last release, and about 60 issues have been solved. 57 people contributed with
code in 105 days. Approximately 2000 files have been touched with 129000
insertions and 25000 deletions.

RIOT-2018.10 - Release Notes

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 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-2018.04 - Release Notes

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.

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)

RIOT-2017.10 - 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 microcontrollers, 16-bit
microcontrollers and light-weight 32-bit processors.

About this release:

Most notable, this release is bringing RIOT a step closer to supporting
over-the-air-updates by containing initial support for MCUBoot.
Furthermore, it adds support for some new platforms (e.g. arduino-mkzero,
nucleos, and frdm-k22f), drivers (e.g. my9221, apa102, ds1307), and of course
a large number of bug fixes (e.g. make buildtest now working properly,
various fixes to xtimer).

About 390 pull requests with about 500 commits have been merged since the last
release and about 60 issues have been solved. 39 people contributed with code
in 113 days. 1825 files have been touched with 223454 insertions and 66146 deletions.

Fixed Issues from the last 3 releases (known issues missing in 2017.04 and 2017.07)

#2006: cpu/nrf51822: timer callback may be fired too early
#4841: xtimer: timer already in the list:
#4590: pkg: building relic with clang fails.
#4694: drivers/lm75a: does not build
#4902: xtimer: xtimer_set: xtimer_set does not handle integer overflows well
#5128: make: buildtest breaks when exporting FEATURES_PROVIDED var
#5207: make: buildest fails with board dependent application Makefiles
#5361: cpu/cc26x0: timer broken
#5460: cpu/samd21: i2c timing with compiler optimization
#5489: cpu/lpc11u34: ADC broken
#5799: kw2x: 15.4 duplicate transmits
#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()
#6022: pkg: build order issue
#6331: RTC alarm triggered with 1s delay
#6419: cpu/cc2538: timer broken
#6427: xtimer: infinite loop with xtimer_mutex_lock_timeout
#6501: boards/nucleo: Pin usage collision (SPI clk vs. LED0)
#6542: boards/nucle-f0xx: misconfigured timer configuration
#6904: cpu/saml21: cannot use several EXTI

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: gnrc: potential racey memory leak
#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
#6519: driver/mrf24j40: broken on stm32f4discovery
#7035: lwIP: hangs due to sema change after a while
#7727: pkg: libcoap is partially broken and outdated

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

#5338: xtimer: xtimer_now() not ISR safe for non-32-bit platforms.
#6052: tests: xtimer_drift gets stuck: xtimer_drift application freezes after ~30-200 seconds
#6502: cpu/stm32l1: RTC broken
#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 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
#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
#7206: native: race-condition in IPC

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
#2143: unittests: tests-core doesn't compile for all platforms: GCC build-ins were used in the
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)
#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
#5405: Eratic timings on iotlab-m3 with compression context activated
