A [major or minor](https://docs.cloud.google.com/data-fusion/docs/concepts/versioning#versioning_scheme)
version of Cloud Data Fusion environment is supported for a specific period of
time after it is released. During that period, Cloud Data Fusion instances
that use the environment version are supported. After that period, instances
that continue to use the environment version are no longer supported. When a
version is not supported, existing instances will continue to work, but no new
instances can be created. No additional fixes will be made and, if you have
issues, Cloud Customer Care will recommend upgrading your environment to the latest
version.

Cloud Data Fusion version support is defined as follows:

- 0-18 months after a major or minor version of Cloud Data Fusion
  environment is released: Cloud Data Fusion instances running the version
  are supported.

- Beyond 18 months after a major or minor version of Cloud Data Fusion
  environment is released: Cloud Data Fusion instances running the version
  are unsupported and need to be updated to regain support.

> [!NOTE]
> **Note:** No emergency bug fixes or security fixes will be provided for unsupported versions for Cloud Data Fusion.
