RIOT-2020.10 - 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 2020.10 release includes:
|
||||
|
||||
- Support for PicoLIBC as standard C library implementation
|
||||
- A new radio abstraction layer for ieee802.15.4 radios
|
||||
- Improvement to the linking of modules
|
||||
- An improved algorithm for generating local unique identifiers
|
||||
- Pagewise addressing support for MTD devices
|
||||
- 23 additional modules supported by Kconfig
|
||||
- Initial rework of the clock modelling on stm32 devices
|
||||
- 5 new boards, 2 new device drivers, 7 packages updated
|
||||
|
||||
482 pull requests, composed of 1355 commits, have been merged since the
|
||||
last release, and 84 issues have been solved. 64 people contributed with
|
||||
code in 94 days. 2426 files have been touched with 133358 (+) insertions and
|
||||
756906 deletions (-).
