How about versiondate?

[silversmurf]

Do you think about implementing optional property versiondate in release? It doesn't matter which kind of style it is (without terrible datehandling) just treat it as String.

Something like that (diffferent kinds of dates):

<changelog>
    <release version="1.1" versioncode="11" versiondate="2015-02-23">
        <change>Totally new and shiny version</change>
    </release>
    <release version="1.0" versioncode="10" versiondate="02/23/2015">
        <change>Fixed: A bug fix</change>
        <change>Some other changes I can't quite remember</change>
    </release>
    <release version="0.1" versioncode="1" versiondate="23.02.2015">
        <change>First release</change>
    </release>
</changelog>

And an additional method:

public ChangeLog setVersionDatesVisible(boolean visible) {
    mVersionDates = visible;
    return this;
}

And some lines of code on other locations, but nothin difficult.
