AWS CodePipeline introduces pipeline variable check rule for stage level condition

AWS CodePipeline V2 type pipelines introduces pipeline variable check as a new rule that customers can use in their stage level condition to gate a pipeline execution. You can use this rule with any condition that is evaluated before entering the stage, before exiting a stage - when all actions in the stage have completed successfully, or when any action in the stage has failed. With the variable check rule, you can evaluate a pipeline parameter or an output variable from a prior action in the pipeline against a threshold, to determine if the condition will succeed or fail. For example, you can check if an output variable from a CodeBuild action is a certain value to determine if the pipeline execution should enter a stage. To learn more about using the variable check rule in stage level conditions in your pipeline, visit our [documentation](https://docs.aws.amazon.com/codepipeline/latest/userguide/rule-reference-VariableCheck.html).

The stage level conditions feature is available in [all regions ](https://aws.amazon.com/about-aws/global-infrastructure/regional-product-services/)where AWS CodePipeline is supported.
