RIOT-2024.10 "FlexTape" - 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

Highlights of the 2024.10 release:

This release fixes some long-standing packet buffer leaks that occurred when using
gnrc_netif_pktq and 6LoWPAN or netdev_new_api (#20983, #20834).

A long standing-bug in the CC2538 radio driver has been fixed when processing
corrupted frames, that before could render the device unresponsive. This can be
triggered due to radio interference, but we also believe that an attacker within range
of the radio could send crafted frames to reliably trigger the issue. We therefore
consider this a denial of service vulnerability and advise all users of the CC2538 to
upgrade to 2024.10 or cherry-pick 1b61216. More
details are published in the security advisory.

With SUIT it is now easier to accept firmwares signed with different keys,
e.g., a node build and signed with a development key can be configured to
accept images signed with either the development key or the production key (#21019).
The public keys are now also stored on the developer's machine, so if a
encrypted private key is used, you don't need the decryption password to build
a firmware, only for signing it (#20862).

THREAD_CREATE_STACKTEST is now the default when DEVELHELP is used.

This release saw the addition of the adafruit-metro-m4-express board.

129 pull requests, composed of 255 commits, have been merged since the
last release, and 5 issues have been solved. 29 people contributed with
code in 119 days. 502 files have been touched with 142126 (+) insertions and
1896 deletions (-).

RIOT-2024.01 - 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 2024.01 release includes:

  • Breaking change for board definition due to XFA for pointers to defined MTD.
    This means users will need to:
    • remove the MTD_NUMOF definition from board.h
    • add MTD_XFA_ADD(<mtd_dev>, <idx>); to the definition of <mtd_dev>.
    • MTD_0, MTD_1, … defines are no longer needed. Use mtd_dev_get(0),
      mtd_dev_get(1), … instead.
  • Many fixes to peripherals due to the periph testing shield
  • The AVR-8 now has power management
  • The ESP32 family is now supported by the SDMMC peripheral driver
  • native now is supported in pyterm
  • tests/periph/uart_locate_pins helps discover which pins are where
  • the periph_timer API supports periph_timer_query_freqs
  • The GNRC boarder router application supports ZEP topology
  • Removal of Kconfig dependency modelling (but still configurations supported)

194 pull requests, composed of 475 commits, have been merged since the
last release, and 4 issues have been solved. 30 people contributed with
code in 64 days. 1083 files have been touched with 36196 (+) insertions and

RIOT-2023.07 - 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

This release sees the addition of the openDSME IEEE 802.15.4 MAC.
So far it is limited to 2.4 GHz O-QPSK and drivers that have been converted
to the new sub-MAC architecture yet.

We also have two new supported MCUs: nRF53 and ATmega8. They share common
peripherals with their siblings, for nRF53 only the application core is
supported so far.

Finally, all tests live in subdirectories now, so the tests/ directory is much
more orderly.

288 pull requests, composed of 661 commits, have been merged since the
last release, and 35 issues have been solved. 26 people contributed with
code in 96 days. 6844 files have been touched with 251875 (+) insertions and
224148 deletions (-).

RIOT-2023.01 - 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

We are proud to announce the release of RIOT 2023.01, marking the tenth
anniversary of the project. Over the past decade, RIOT has become a thriving
open-source community, delivering cutting-edge technology for Internet of
Things (IoT) devices. This release builds on top of the hard work and
dedication of our developers, users, and contributors, and we would like to
extend a heartfelt thank you to everyone who has been a part of our journey.
Here's to another decade of innovation and growth!

Noteworthy changes the 2023.01 release includes, among many fixes and little
things:

  • ztimer_ondemand: The next step towards seamless and automatic power management.
  • The Rust examples now default to stable Rust.

187 pull requests, composed of 570 commits, have been merged since the
last release, and 13 issues have been solved. 37 people contributed with
code in 58 days. 1248 files have been touched with 516544 (+) insertions and

RIOT-2022.10 - 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 2022.10 release includes, among many many bug fixes and improvements, the
following prominent contributions:

Security Fixes

The GNRC network stack has received a number of security fixes. All users of
GNRC are advised to update to the new release. Given that no user facing
breaking API changes are included, we are hopeful that the update is painless
and quickly possible.

ESP32 family

RIOT has been ported to the ESP32-C3, ESP32-S2, and the ESP32-S3 MCUs. In
addition driver support for the integrated BLE transceiver of the ESP32 MCUs
has been added.

Major CI Upgrade

While the CI is developed in an independent repository, it is still a noteworthy
change that our CI software, Murdock, was updated since the last release. In
addition to changes under the hood the web front end got a major revamp. You
will directly notice the improvements in page load time and clarity/structure of
the interface. If you haven't already, please check out https://ci.riot-os.org
to take a look.

Support for Priority Inheritance in core_mutex

If a shared resource guarded by a mutex is used by a high priority and a low
priority thread, the high priority thread may end up waiting on the low priority
thread to return the resource. If medium priority threads now interrupt the
low priority thread while working with the shared resource, the high priority
thread ends up waiting on both medium and low priority threads. This effect is
called priority inversion.

Priority inversion can in most cases be solved by carefully assigning priorities
and resources. In some cases however, this cannot be avoided: Let's consider
a scenario in which an I2C temperature sensor and an I2C IMU are used. Since
temperature changes are slow in frequency, the temperature readings are
assigned the lowest priority, while the IMU readings are assigned the highest
priority. The sensible approach here is to have both sensors on distinct I2C
buses. However, if e.g. only a single I2C bus is available by the hardware
priority inversion cannot be prevented by careful resource and priority
assignment alone. In these cases the module core_mutex_priority_inheritance
can be used to lend the low priority thread the priority of the high priority
thread while the high priority thread is waiting for the mutex hold by the
low priority thread.

After RIOT has already been launched into space
it is now ready to for
Mars.

USB Support for STM32F1 MCUs

While RIOT has longstanding USB support for many STM32 MCU families, the F1
family was not supported due to some peculiarities in the memory layout. The
driver has now been extended to handle them correctly. With this, the popular
STM32F103 bluepill board now supports stdio via USB, which however still
has to be manually enabled e.g. by:

USEMODULE=stdio_cdc_acm BOARD=bluepill make -C examples/default

Support for podman

Just add an export DOCKER=podman to your ~/.profile (or ~/.bashrc, or ...)
and an make BUILD_IN_DOCKER=1 will use podman instead of
docker to run the RIOT build container. Two major advantages of using podman
over docker is the support of rootless containers and not depending on a
central background daemon.

Support for Sharing nRF52 combined I2C/SPI Peripherals

The nRF52 MCUs have a limited number of combined I2C/SPI peripherals.
Previously, each such peripheral could either provide a single I2C or a
single SPI bus. A board configuration that used the same combined peripheral
to provide both an SPI and an I2C bus previously resulted in bad surprises at
run-time.

The I2C/SPI drivers have now been reworked so that they can be shared in
round-robin fashion between multiple I2C and SPI buses. This is especially
useful for the upcoming support of the Bangle.js 2 watch that uses more I2C
buses than combined I2C/SPI peripherals available on the used nRF52840 MCU.
Thanks to the sharing of peripherals, all I2C buses can now be provided by a
single peripheral.

Support for GCC 12.2.0

Many fixes for compilation and runtime issues that only started to surface
with GCC 12.2.0 have been fixed. This allows our users to confidentially choose
the current release with little to no fear that toolchain updates in the near
future will break the precious projects. In addition, we hope that the next
CI update will also cause less friction.

RIOT-2022.07 - 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 2022.07 release includes many changes, some highlights of which are:

GPIO Low-level drivers

A new API, gpio_ll, has been introduced for highly efficient access to GPIO
pins grouped in ports.

The API is limited to internal use for the time being, but still paves the way
towards using port multipliers like local GPIO pins, and for improved
bit-banging implementations (e.g. around WS281x-style LEDs).

Improved serial port selection

When using multiple boards simultaneously, a new serial port selection
algorithm can be activated by setting MOST_RECENT_PORT=1. Of all serial ports
whose metadata matches the board's known properties, it selects the most
recently connected one.

ESP support

The ESP IDF (IoT Development Framework; the vendor's provided tools) has been
upgraded to version 4.4, and many peripheral drivers are now implemented using those.

343 pull requests, composed of 767 commits, have been merged since the
last release, and 5 issues have been solved. 38 people contributed with
code in 107 days. 1684 files have been touched with 43451 (+) insertions and
82174 deletions (-).
