RELEASE 2018.07
RIOT-2018.07 - 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 2018.07 release includes new features, like NimBLE (ble stack),
a MQTT-SN client, SHA-1 based PRNG, an UUID implementation. The RISC-V CPU
architecture support used by the hifive1 board.
Effort was done on refactoring, documentation, test improvements and bug fixes.
During the last release, maintainers contributed by running the automated test
suites on their boards. This gave valuable feedback on the board support state,
test reliability and where to focus effort to make testing easier and more
reliable.
About 380 pull requests with about 675 commits have been merged since the last
release and about 27 issues have been solved. 45 people contributed with code
in 93 days. Approximately 1678 files have been touched with 147122 insertions
and 16060 deletions.
