Cloud Client Libraries for Go are compatible with the two most-recent major Go releases, the same policy the Go programming language follows. This means that Cloud Client Libraries for Go are compatible with all supported Go releases. For example, if the current Go release is Go 1.23, the Cloud Client Libraries for Go are compatible with Go 1.22 and Go 1.23. For more information on Cloud Client Libraries, see Client libraries explained.
For new development
When starting a new project, we recommend choosing the current release of Go if possible. This ensures that your runtime is within the supported Go releases and receives critical security patches.
Keeping production systems current
Keeping your production systems on supported Go runtimes is the best way to ensure that you receive critical security and bug fixes. Our Go Cloud Client Libraries increment a minor version when dropping compatibility with an earlier Go runtime version. For more information about the use of major and minor versions, see Semantic Versioning.
Where to find version information
To find out what Go versions are supported, see the google-cloud-go README.
