Software maturity levels

The nRF Connect SDK supports its various features and components at different levels of software maturity. The tables on this page summarize the maturity level for each feature and component supported in the nRF Connect SDK.

Software maturity categories

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 and a build warning is generated to indicate this status.

See the following table for more details:

Software maturity

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 and security fixes will be resolved in both main and the latest tagged versions.

Bug fixes, security 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.

For the certification status of different features in a specific SoC, see its Compatibility Matrix in the Nordic Semiconductor TechDocs.

API deprecation

The Deprecated status is assigned to API that has gone through all maturity levels, but is being phased out. The deprecated API will be removed in one of future releases, no earlier than two releases after the deprecation is announced and only when the code has transitioned to not using the deprecated API. The experimental API can be removed without deprecation notification. Following Zephyr’s guidelines for API lifecycle, the API documentation informs about the deprecation and attempts to use a deprecated API at build time will log a warning to the console.

Application support

The following subsections indicate the software maturity levels of the support for applications.

Note

Features not listed are not supported.
