Constants
It is possible to associate a list of constants (= key-value pairing) with each project, through the Projects → {Requested Project} → Constants menu.
Some task types (currently Local command, Bash script, Powershell script, Ansible playbook, and SQL report) may refer to them to avoid hard-coding certain common values.
The main advantage of project constants is that you can quickly adapt the behavior of several tasks simply by updating the values assigned to these constants.
