**AL2027 Preview**  
AL2027 is currently available for preview. It is intended for evaluation and testing only and is not recommended for production workloads.

You can find out about new AL2027 releases in the following ways:
+ Each release is documented in the [AL2027 Release Notes](https://docs.amazonaws.cn/linux/al2027/release-notes/relnotes.html), including the package changes it contains.
+ On a running instance, the `dnf check-release-update` command reports when a newer release than the one the system is locked to is available. For more information, see [Checking for newer repository versions with `dnf check-release-update`](manage-updates.md#dnf-repository-updates).
+ An Amazon SNS topic sends a notification each time we release a new AL2027 AMI. This page includes the subscription steps.

[Amazon SNS](https://www.amazonaws.cn/sns/) publishes a notification to the following topic each time we release a new AL2027 AMI.
