RELEASE 2019.01
RIOT-2019.01 - 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 2019.01 release includes a number of new features including DMA support on
all STM32 boards, WiFi with IP connectivity on ESP32 and ESP8266, and riotboot,
a simple bootloader supporting multiple firmware slots, compatible with most Arm
Cortex-M boards supported by RIOT. Support for several new boards and new sensors
was added, as well as for the new CPU architecture Armv8-M (Cortex-M23). Last
but not least, this release contains a number of bug fixes and enhances test
automation.
About 387 pull requests with about 912 commits have been merged since the last
release and about 36 issues have been solved. 54 people contributed with code
in 110 days. Approximately 1554 files have been touched with 176241 insertions
and 50593 deletions.
