GET https://api.cdnjs.com/libraries/datatables.net?fields=versions returns

{
    "versions": [
        "1.10.12",
        "1.10.13",
        "1.10.14",
        "1.10.15",
        "1.10.16",
        "1.10.18",
        "1.10.19",
        "1.10.20",
        "1.10.21",
        "1.10.22",
        "1.10.23",
        "1.10.24",
        "1.10.25",
        "1.11.0",
        "1.11.1",
        "1.11.2",
        "1.11.3",
        "1.11.4",
        "1.11.5",
        "1.12.0",
        "1.12.1",
        "1.13.0",
        "1.13.1",
        "1.13.10",
        "1.13.11",
        "1.13.2",
        "1.13.3",
        "1.13.4",
        "1.13.5",
        "1.13.6",
        "1.13.7",
        "1.13.8",
        "2.0.0",
        "2.0.1",
        "2.0.2",
        "2.0.3",
        "2.1.1"
    ]
}

One would naively assume from this response that 2.1.1 is the latest version of the package, but in reality it is a deprecated version (https://www.npmjs.com/package/datatables.net/v/2.1.1). It would be nice if the API either offered an option to exclude deprecated versions when making the request or included deprecation metadata in the response.

This issue was originally raised here: aspnet/LibraryManager#724.
