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.

RELEASE 2017.10 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. 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).

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. Notations used below: ===================== + means new feature/item * means modified feature/item - means removed feature/item New features and changes ======================== Bootloader ----------- + MCUBoot: A secure bootloader for ARM MCUs is now supported. This initial support includes only the nrf52dk board. For more information about it refer to the mcuboot github page at https://github.com/runtimeco/mcuboot/blob/master/README-RIOT.rst System libraries ---------------- + bcd: binary coded decimal en/decoder Networking ---------- + gcoap: Add URI-query strings for requests + various fixes Packages -------- * lwip: Updated to v2.0.3 Boards ------ + NXP frdm-k22f + STM nucleo144-f722 + Arduino arduino-mkzero + ti CC2650 LaunchPad - weio CPU --- + NXP k22f + cc2538: ADC + stm32l4: RTC + samr21e18a + msp430: added flashpage driver - lpc11u34 * stm32: unified stmclk implementations, reworked RTC * sam0: heavy unification and refactoring, updated vendor headers + sam_common: started unification of sam0 and sam3 * cortexm: interrupt vector cleanup Device Drivers -------------- + my9221 - LED controller + Seeed Studio Grove LED bar + apa102 - RGB LED + ds1307: RTC + SAUL support: lps331ap * SAUL gpio: allow configuration of initial state and low-active signals * sdcard_spi: added mtd interface * PM: fixed selection of default implementations for `pm_off` and `pm_set_lowest` Build System / Tooling ------------ + make: added pkt-prepare target * gcc: enabled `-fdiagnostics-color` per default for `arm` and `native` targets * edbg: use as default flash tool for sam0-based boards + added LOSTANDFOUND.md for listing removed features 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.

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 \#5486: at86rf2xx: lost interrupts \#5678: at86rf2xx: failed assertion in _isr \#5944: msp430: ipv6_hdr unittests fail \#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 \#7347: xtimer_usleep stuck for small values on nucleo-l1 \#7753: pic32-wifire: race-condition when linking in concurrent build \#7846: stm32f1: I2C read functions return bogus values with unconnected devices other issues ------------ \#1263: TLSF implementation contains (a) read-before-write error(s). \#3256: make: Setting constants on compile time doesn't really set them everywhere \#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. \#4866: periph: GPIO drivers are not thread safe \#5561: C++11 extensions in header files \#5776: make: Predefining CFLAGS are parsed weirdly \#5863: OSX + SAMR21-xpro: shell cannot handle command inputs larger than 64 chars \#5962: Makefile: UNDEF variable is not working as documented \#6451: Wrong value in SRF08 driver \#7800: CBOR is broken Special Thanks ============== We would like to give our special thanks to all the companies that provided us with their hardware for porting and testing, namely the people from (in alphabeticalorder): Atmel, Freescale, Imagination Technologies, Nordic, OpenMote, Phytec, SiLabs, UDOO, and Zolertia; and also companies that directly sponsored development time: Cisco Systems, Eïsox, Eistec, Ell-i, Engineering Spirit, Mesotic, Nordic, OTA keys and Phytec.
