RELEASE 2019.10 RIOT-2019.10 - 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 2019.10 release includes: - initial support for SUIT firmware updates - USB CDC-ACM serial communication - complete rewrite of TI CC110x radio driver - initial support for IPv6 fragmentation - DTLS support in the sock networking stack - complete blockwise messaging for gcoap and nanocoap - as always, bug fixes and documentation updates About 460 pull requests, composed of 950 commits, have been merged since the last release, and about 60 issues have been solved. 57 people contributed with code in 105 days. Approximately 2000 files have been touched with 129000 insertions and 25000 deletions.

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.
