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

As the release was finalized, rough consensus was reached on a system event
thread handler (RIOT-OS#12474) that likely will remove the interrupt handler thread
(RIOT-OS#10555) just introduced with this release.

RELEASE 2019.07
RIOT-2019.07 - 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 2019.07 release includes a number of new features including many new
boards and cpu, riotboot added to many new and old boards, USB is now available,
BLE improvements, Ethernet on stm32 platforms, as well as many bug fixes and
documentation updates. Testing has also improved with both On-Target Testing
increasing and now Hardware Assisted Automated Tests being run.
About 300 pull requests with about 659 commits have been merged since the last
release and about 50 issues have been solved. 26 people contributed with code
in 106 days. Approximately 1377 files have been touched with 181993 insertions
and 19668 deletions.
