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.

RIOT-2019.04 - 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 2019.04 release includes a number of new features including porting of
riotboot to a number of new platforms, 802.15.4 support on the nRF52, and the
ability for firmware to flash images into a separate boot slot. Support for
several new boards and new sensors was added. Additionally, this release
contains a number of bug fixes and test improvements.
About 320 pull requests with about 569 commits have been merged since the last
release and about 40 issues have been solved. 44 people contributed with code
in 88 days. Approximately 825 files have been touched with 32716 insertions
and 5149 deletions.

Acknowledgements
================
We would like to thank all companies (vendors) that provided us with (their)
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-2019.01 - 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 2019.01 release includes a number of new features including DMA support on
all STM32 boards, WiFi with IP connectivity on ESP32 and ESP8266, and riotboot,
a simple bootloader supporting multiple firmware slots, compatible with most Arm
Cortex-M boards supported by RIOT. Support for several new boards and new sensors
was added, as well as for the new CPU architecture Armv8-M (Cortex-M23). Last
but not least, this release contains a number of bug fixes and enhances test
automation.
About 387 pull requests with about 912 commits have been merged since the last
release and about 36 issues have been solved. 54 people contributed with code
in 110 days. Approximately 1554 files have been touched with 176241 insertions
and 50593 deletions.
