Thus far the only way you could add an environment variable to you project was to include an export SECRET_TOKEN=abcd123 command in your build configuration. But from now on you can use our project settings interface to manage your project’s environment variables.
Apart from being easier to use, the new interface gives you the ability to encrypt values of your variables. We strongly recommend that you select this option if you are storing some sensitive data in your variables.
Note that you can also keep your export SECRET_TOKEN=abcd123 build commands if you prefer.
