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.

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

RIOT-2019.07 - 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 2019.07 release includes a number of new features including many new
boards and cpu, riotboot added to many new and old boards, USB is now available,
BLE improvements, Ethernet on stm32 platforms, as well as many bug fixes and
documentation updates. Testing has also improved with both On-Target Testing
increasing and now Hardware Assisted Automated Tests being run.
About 300 pull requests with about 659 commits have been merged since the last
release and about 50 issues have been solved. 26 people contributed with code
in 106 days. Approximately 1377 files have been touched with 181993 insertions
and 19668 deletions.
