+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.
