This document details the policy for maintaining stability of SPDK ABI and API.
|
|
|
|
|
|
|
|
|
|
Major ABI version can change at most once for each quarterly SPDK release.
|
|
|
|
|
ABI versions are managed separately for each library and follow [Semantic Versoning](https://semver.org/).
|
|
|
|
|
|
|
|
|
|
API and ABI deprecation notices shall be posted in the next section.
|
|
|
|
|
Each entry must describe what will be removed and can suggest the future use or alternative.
|
|
|
|
|
Specific future SPDK release for the removal must be provided.
|
|
|
|
|
ABI cannot be removed without providing deprecation notice for at least single SPDK release.
|
