We are happy to announce the 24th official release of RIOT:
----------------------- * RIOT 2020.07 * -----------------------
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 . 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.
