Testing a function before putting it in production is usually a wise decision. To handle this VXL supports multiple function version. A function can be edited as a new version and this version can be made available for just the test environment. It can later be deployed to production.
When editing a function the user will be able to choose between updating existing version and creating a new version. Please note that updating the existing version will affect all environments the version is deployed to.
Please note: When the function version is saved, it will currently be added to every environment the user has write access to. To undeploy the version from an environment click "Map Environments"
