RELEASE 2019.04
RIOT-2019.04 - 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 2019.04 release includes a number of new features including porting of
riotboot to a number of new platforms, 802.15.4 support on the nRF52, and the
ability for firmware to flash images into a separate boot slot. Support for
several new boards and new sensors was added. Additionally, this release
contains a number of bug fixes and test improvements.
About 320 pull requests with about 569 commits have been merged since the last
release and about 40 issues have been solved. 44 people contributed with code
in 88 days. Approximately 825 files have been touched with 32716 insertions
and 5149 deletions.

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.
