#14817: gnrc_sixlowpan_frag_rb: Check possibly uninitialized pointers
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 (-).

Acknowledgements
================
We would like to thank all companies that provided us with hardware for porting
and testing RIOT-OS. Further thanks go to companies and institutions that
directly sponsored development time. And finally, big thanks to all of you
contributing in so many different ways to make RIOT worthwhile!

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.
