Software maturity levels

The nRF Connect SDK supports its various features and components at different levels of software maturity. The tables at the end of this page summarize the maturity level for each feature and component supported in the nRF Connect SDK. The following categories are used in the tables to classify the software maturity of each feature and component:

Supported

The feature or component is implemented and maintained, and is suitable for product development.

Not supported

The feature or component is neither implemented nor maintained, and it does not work.

Experimental

The feature can be used for development, but it is not recommended for production. This means that the feature is incomplete in functionality or verification and can be expected to change in future releases. The feature is made available in its current state, but the design and interfaces can change between release tags. The feature is also labeled as EXPERIMENTAL in Kconfig files to indicate this status.

Note

By default, the build system generates build warnings to indicate when features labeled EXPERIMENTAL are included in builds. You can disable these warnings by disabling the CONFIG_WARN_EXPERIMENTAL kconfig option. See nRF Connect SDK additions for details.

Technical support

Customer issues raised for features supported for developing end products on tagged nRF Connect SDK releases are handled by technical support on DevZone.

Customer issues raised for experimental features on tagged nRF Connect SDK releases are handled by technical support on DevZone.

Not available.

Bug fixing

Reported critical bugs will be resolved in both main and the latest tagged versions.

Bug fixes and improvements are not guaranteed to be applied.

Not available.

Implementation completeness

Complete implementation of the agreed features set.

Significant changes may be applied in upcoming versions.

A feature or component is available as an implementation, but is not compatible with (or tested on) a specific device or series of products.

API definition

The API definition is stable.

The API definition is not stable and may change.

Not available.

Maturity

Suitable for integration in end products.

A feature or component that is either fully complete on first commit, or has previously been labelled experimental and is now ready for use in end products.

Suitable for prototyping or evaluation. Not recommended to be deployed in end products.

A feature or component that is either not fully verified according to the existing test plans or currently being developed, meaning that it is incomplete or that it may change in the future.

Not applicable.

Verification

Fully verified according to the existing test plans.

Incomplete verification

Not applicable.
