RELEASE 2021.01
RIOT-2021.01 - 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 2021.01 release includes:
- Device Firmware Upgrade support for USBUS
- USB HID minimal implementation
- IEEE 802.15.4 security initial implementation
- 6LowPAN Minimal Forwarding and Selective Fragment Recovery initial
implementation
- Initial support for QN808x, SAMD10 STM32MP1 and STM32L5 CPUs
- Initial support for Cortex-M33
- A module for selecting entropy sources
- Initial support for the Decawave Impulse Radio-Ultra Wideband (UWB Core)
- Capability to join or leave link layer multicast groups (GNRC)
- Support for IN865 region in GNRC LoRaWAN
- 83 additional modules supported by Kconfig
- 14 new boards, 6 new device drivers, 8 packages updated
In order to improve community interaction, during this release cycle we started
to migrate from a mailing-list-based communication to forum-based
communication. We are proud to present the RIOT-OS forum available at
forum.riot-os.org
533 pull requests, composed of 1440 commits, have been merged since the
last release, and 65 issues have been solved. 58 people contributed with
code in 119 days. 3852 files have been touched with 348619 (+) insertions and
52516 deletions (-).
