 `TDLib` provides efficient native C++, Java, and .NET interfaces.

 `TDLib` JSON interface adheres to semantic versioning and versions with the same major version number are binary and backward compatible, but the underlying `TDLib` API can be different for different minor and even patch versions.
 If you need to support different `TDLib` versions, then you can use a value of the `version` option to find exact `TDLib` version to use appropriate API methods.
