RIOT-2020.01 - 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.

RIOT-2018.10 - Release Notes

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 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.

RIOT-2018.07 - Release Notes

About this release:

The 2018.07 release includes new features, like NimBLE (ble stack),
a MQTT-SN client, SHA-1 based PRNG, an UUID implementation. The RISC-V CPU
architecture support used by the hifive1 board.
Effort was done on refactoring, documentation, test improvements and bug fixes.

During the last release, maintainers contributed by running the automated test
suites on their boards. This gave valuable feedback on the board support state,
test reliability and where to focus effort to make testing easier and more
reliable.

About 380 pull requests with about 675 commits have been merged since the last
release and about 27 issues have been solved. 45 people contributed with code
in 93 days. Approximately 1678 files have been touched with 147122 insertions
and 16060 deletions.

RIOT-2018.04 - Release Notes

About this release:

The 2018.04 release includes major progress in support for current crypto
libraries. A lot of work has gone into updating drivers to RIOT's unified
configuration scheme. Support for ten new boards has been added. In our quest
to improve and automate testing, many test scripts have been fixed and
improved, and RIOT's CI now runs many tests on real hardware during its nightly
build testing. And as usual, many tiny fixes and improvements have been merged.

Release-2018.01

RIOT-2018.01 - Release Notes

About this release:

The 2018.01 release includes major progress in RIOTs network communication
capabilities, i.e., rewrite of GNRC's neighbour discovery, confirmable messages
in (g)CoAP, LoRa, and GoMacH as well as updates on CCN-lite and LWIP.
Furthermore, RIOT contributes to IKEA-Hacking by bringing support for
the smart home lighting system TRADFRI (note: this will void the warranty).
Needless to say that this release also adds and updates support for several
platforms, drivers, and of course lots of enhancements to the documentation
as well as numerous bug fixes. Last but not least, RIOT now has an official
code of conduct (https://github.com/RIOT-OS/RIOT/blob/master/CODE_OF_CONDUCT.md)

More than 442 pull requests with about 865 commits have been merged since the
last release and about 96 issues have been solved. 54 people contributed with code
in 96 days. Approximately 2370 files have been touched with 223970 insertions
and 181409 deletions.
