This topic describes the C++ SDK version information, including the download link, release time, and updates, so that you can obtain the applicable C++ SDK to send and subscribe to messages as needed.
After obtaining the C++ SDK, you need to prepare the corresponding environment according
to SDK instructions. The environment preparation steps vary with SDK versions.
- For more information about how to prepare the environment for SDK v2.0.0, see Prepare the environment (v2.0.0).
- For more 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).
