About preview features
Imply Long Term Support (LTS) releases and Short Term Support (STS) releases include preview features that are at one of two possible lifecycle stages:
Alpha: An alpha feature may include major bugs or performance issues. It may also be otherwise feature-limited. Alpha features are not ready for production use, but are instead suitable for feature previews and learning environments.
Alpha features may be subject to significant changes or removal without prior notice.
Beta: Beta features should be suitable for production scenarios. However, you should only enable a beta feature after testing in a staging environment. When you feel comfortable to move to production, enable beta features in closely monitored scenarios.
