This topic describes the download links, release date, and updates of the SDK for C++. You can use the applicable SDK for C++ to send and subscribe to messages based on your business requirements.
After you obtain the SDK for C++, you must prepare an environment for the SDK based
on SDK instructions. The environment preparations vary based on SDK versions.
- For information about how to prepare the environment for SDK v2.0.0 or later, see Prepare the environment (v2.0.0).
- For information about how to prepare the environment for SDK v1.x.x and upgrade it to SDK v2.0.0, see Prepare the environment (v1.x. x).
