AWS CodePipeline Adds Execution Visualization to Pipeline Execution History
You can now view visualizations of past pipeline executions in AWS CodePipeline. Previously, you were only able to see information about actions that ran in a failed pipeline execution. Now, when an execution fails, you will also see the actions that did not run enabling easier debugging of pipeline failures. When your pipeline has concurrent executions, you are now able to view visualizations of the individual executions making understanding the status of an execution much simpler.
