RIOT-2022.04 - 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 2022.04 release includes the following new features and improvements:
Core:
-----
The scheduler allows for changing the priority of a thread at runtime.
System libraries:
-----------------
The module `ztimer64_xtimer_compat` was added, providing the complete xtimer
API on top of ztimer64_usec. This is now the default implementation when using
the `xtimer` module.
Most modules use ztimer instead of xtimer now.
The sequence of modules during auto initialization can be customized via
statically assigned numbers now. This feature is experimental, so use it with
caution. Priorities may change in the future.
SenML implementation: supports CBOR encoding, Phydat to SenML encoding and
basic SAUL integration.
Various improvements have been made to the file system modules:
VFS supports automatic mount (and formatting) at startup and reliable disk
enumeration, and mount_by_path. Default mount points can be provided by the
board configuration. exFAT support was added to FATFS.
Using Rust in RIOT no longer requires a nightly version of Rust, but can be
built on the latest stable on Rust instead.
Boards:
-------
Boards no longer have to provide a `board_init()` function. LEDs are
initialized automatically if they follow the `LED<x>_PIN` naming scheme.
Networking:
-----------
gcoap now provides a simple forward-proxy and allows for switching between
plain CoAP and CoAP-over-DTLS at runtime.
The NimBLE module supports the new PHY modes that have been introduced with
Bluetooth 5.
A Telnet server module is available now.
Packages:
---------
The build system now allows for package directories to reside outside the RIOT
tree.
Various new packages have been added:
* the C++ Embedded Template Library (ETL)
* nanors, a tiny, performant implementation of reed solomon codes
* tflite-micro as a replacement for tensorflow-lite
* WAMR adds Web assembly (WASM) support
Hardware support:
-----------------
New support for the boards Adafruit-PyBadge and STM32 Nucleo-F439ZI as well as
for the LPS22CH nano pressure sensor and MCP47xx DAC. The DOSE bus now supports
baud rates of 1 MHz and above.
Summary:
-------
328 pull requests, composed of 810 commits, have been merged since the
last release, and 6 issues have been solved. 40 people contributed with
code in 83 days. 1851 files have been touched with 50235 (+) insertions and
18701 deletions (-).

RIOT-2022.01 - 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 2022.01 release brings support for new packages, new boards and drivers,
as well as several package upgrades and bug fixes. Among others, this release
improves the RIOT codebase with:
Rust support
------------
RIOT now offers convenient integration of Rust application programming, with
wrappers interfacing to RIOT modules such as timers, network stack.
Improved timers
---------------
Many modules have migrated from using xtimer to our more power-efficient
alternative ztimer. Also, ztimer64 was introduced, which enables
a drop-in replacement for all of xtimer features.
Kconfig support
---------------
Kconfig modeling coverage is significantly extended. Nearly all supported
boards are now modeled with Kconfig.
Summary:
--------
436 pull requests, composed of 1159 commits, have been merged since the
last release, and 11 issues have been solved. 43 people contributed with
code in 88 days. 2475 files have been touched with 44925 (+) insertions and
14687 deletions (-).
