Supported variables

Note: Some variables can be detected only on certain CI services. See Supported CI.

Note: The pr and prBranch properties are only available for builds triggered when a Pull Request is opened/updated and not on builds triggered by a push on a branch even if that branch happens to be the branch from which the Pull Request originated.
