How does scoop allow installation of a specific application version when the app manifest file contains information only about the latest version?

[alex-vovk-info]

App manifest files contain information only about the latest version of the application.
Here is an example of the app manifest file shown in the Wiki:

{
    "version": "1.0",
    "url": "https://github.com/lukesampson/cowsay-psh/archive/master.zip",
    "extract_dir": "cowsay-psh-master",
    "bin": "cowsay.ps1"
}

How can Scoop support install earlier versions that are no longer specified in the latest app manifest?
