In Azure Devops what does variable scope value Release mean? In the same drop down there are other stages that mean it only applies for that stage. Does Release mean it applies to all stages?
Azure Pipelines releases can deploy artifacts produced by a wide range of artifact sources. such as Azure Pipelines build, Jenkins, or Team City. Define the release pipeline using stages and restrict deployments into or out of a stage using approvals. Define the automation in each stage using jobs and tasks.
As you compose the tasks for deploying your application into each environment, variables will help you to: Define a more generic deployment process once, and then customize it easily for each environment.
To use a variable group, open your pipeline. Select Variables > Variable groups, and then choose Link variable group. In a build pipeline, you see a list of available groups. In a release pipeline, for example, you also see a drop-down list of stages in the pipeline.
Yes, when a variable scope is set to Release
it allows the value to be used across all stages and tasks in the release pipeline. If scope is set to a specific stage, then it is available in that stage only.

And also, if you have a variable with the same name in multiple scopes, it will be used according to the following precedence:
1 means the highest precedence.
This has been explained in detail in Expansion of variables, you can refer to it for more details.
