When backwards-incompatible changes are made to the API, we release a new API version, in the form of a date string, and update the Changelog.

Each Substrate SDK release is pinned to an API version. SDK versions follow semantic versioning (opens in a new tab) with the following components:

<SDK_MAJOR><API_VERSION>.<SDK_MINOR>.<SDK_PATCH>

020240101.3.2 is an example SDK version string with 4 components:

• 0 – SDK_MAJOR – backwards-incompatible SDK changes
• 20240101 – API_VERSION – backwards-incompatible API changes
• 3 – SDK_MINOR – backwards-compatible SDK changes
• 1 – SDK_PATCH – minor SDK changes
