RELEASE 2020.10 RIOT-2020.10 - 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 2020.10 release includes: - Support for PicoLIBC as standard C library implementation - A new radio abstraction layer for ieee802.15.4 radios - Improvement to the linking of modules - An improved algorithm for generating local unique identifiers - Pagewise addressing support for MTD devices - 23 additional modules supported by Kconfig - Initial rework of the clock modelling on stm32 devices - 5 new boards, 2 new device drivers, 7 packages updated 482 pull requests, composed of 1355 commits, have been merged since the last release, and 84 issues have been solved. 64 people contributed with code in 94 days. 2426 files have been touched with 133358 (+) insertions and 756906 deletions (-).

RELEASE 2020.07 RIOT-2020.07 - 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 2020.07 release puts a focus on the improvement of automated testing. In that vein, various new CI integrations such as CircleCI for documentation building and online presentation, and Github Actions to check the tooling of RIOT when merged. The `riotctrl_shell` python module allows to abstract shell commands as python methods for testing using the newly created `riotctrl` python package [1]. Kconfig migration reached phase 2 with various board features being exposed to Kconfig. New network protocols were ported for RIOT such as MQTT (in form of the `paho-mqtt` package) and the lookup client component for CoRE RD `cord_lc`. The OpenWSN network stack with 6TiSCH support was reintegrated into RIOT. Support for several new boards and new sensors was added. Additionally, this release contains a number of bug fixes and test improvements. 546 pull requests, composed of 10452 commits, have been merged since the last release, and 84 issues have been solved. 64 people contributed with code in 106 days. 2371 files have been touched with 822149 (+) insertions and 700313 deletions (-).

2020.04
2020.04 RELEASE 2020.04 RIOT-2020.04 - 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 2020.04 release includes: - Add support for 6LoWPAN IPv6 extension header next header compression - Add support for DHCPv6 prefix delegation client - Add support for kw41zrf and at86rf215 IEEE 802.15.4 radios - Improvements on power management for ESP32 - Improvements and extensions in support of fe310 and lpc2387 - lwIP: provide support for asynchronous sock - Improvements on xtimer module and testing - Initial addition of the new timer subsystem: ztimer - Migration to Kconfig - phase I: add multiple GNRC and system modules - +10 new boards, +11 new drivers, +7 new packages 555 pull requests, composed of 1514 commits, have been merged since the last release, and 22 issues have been solved. 60 people contributed with code in 102 days. 3346 files have been touched with 358398 (+) insertions and 184720 deletions (-).

RELEASE 2020.01 RIOT-2020.01 - 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 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 2020.01 release includes: - Initial support for MicroPython - Initial support for GNRC based LoRaWAN stack - Initial (experimental) asynchronous sock support - Extend support for lpc2387 and fe310 cpus - Xtimer concurrency/robustness improvement, fixing #8388, #5338 & #5103 - Complete re-implementation of esp8266 based on ESP8266 RTOS SDK - Improvements in automatic tests - Introduce and start using Kconfig as a configuration tool - +12 new boards, +7 new drivers, +4 new packages About 527 pull requests, composed of 1367 commits, have been merged since the last release, and about 29 issues have been solved. 61 people contributed with code in 111 days. Approximately 3053 files have been touched with 134416 (+) insertions and 31870 deletions (-).
