Add release notes

[dalton5]

First thanks for the great work.

Is it possible to add the retrieving of release notes please?

The lib works very well.

Thanks,

For iOS:

http://itunes.apple.com/lookup?bundleId=<bundleId> returns a simple JSON response. results[0].releaseNotes gives you back the release notes without ugly HTML parsing and regular expressions:

{
    "resultCount": 1,
    "results": [{
        ...
        "supportedDevices": ["iPhone5s-iPhone5s", ...],
        "kind": "software",
        "minimumOsVersion": "10.0",
        "releaseDate": "2021-01-14T08:00:00Z",
        "currentVersionReleaseDate": "2023-01-10T08:00:33Z",
        "releaseNotes": "NEW:\n* Estimation of the amount of gas consumption.\n\nIMPROVEMENTS:\n* When change was saved, show short info below.\n* Cold water meter can be classified as seasonal\n* More public utilities\n\nFIXES:\n* Wastewater amount is set to 0 when wastewater costs are disabled.\n* Duplicate contracts will be deleted automatically\n* Cost overview not visible only after tab change",
        "version": "1.6.119"
    }] 
}
