nRF Connect SDK v1.8.0 Release Notes
nRF Connect SDK delivers reference software and supporting libraries for developing low-power wireless applications with Nordic Semiconductor products. It includes the TF-M, MCUboot and the Zephyr RTOS open source projects, which are continuously integrated and re-distributed with the SDK.
The nRF Connect SDK is where you begin building low-power wireless applications with Nordic Semiconductor nRF52, nRF53, and nRF91 Series devices. Wireless protocol stacks and libraries may be experimental if they are under development or based on verification and certification status. Labels in Kconfig indicate experimental configurations and can generate warnings in build output if they are used in a project. These configurations should not be used in production. See the release notes and documentation for those protocols and libraries for further information.
