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.

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-2018.10 - 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 2018.10 release includes new features, like CoAP Resource Directory and
Block2, ESP32 support, rework of I2C interface, EEPROM registry,
Full and Minimal Thread Devices support in OpenThread and compliance of
LoRaWAN 1.0.2 (ABP counters stored in EEPROM). Several boards were introduced.
During the last release the board documentation was migrated from the wiki to
the [RIOT API documentation](https://doc.riot-os.org) to improve the
maintenance of these entries and provide a better user experience when
browsing the documentation. There were also some efforts in grouping some
modules to make them easier to access in the documentation.
There were also some efforts on refactoring, test improvements and bug fixes.
About 392 pull requests with about 914 commits have been merged since the last
release and about 20 issues have been solved. 57 people contributed with code
in 100 days. Approximately 2184 files have been touched with 211964 insertions
and 34806 deletions.
