Why is the Reader class deprecated, and what should be used instead?

[edbird]

Apparently Json::Reader has been marked as deprecated. I would be interested to know why this is the case.

It is noted that CharReader or CharReaderBuilder should be used instead.

In which case, what is one to do to replace the following:

Json::Reader reader;
Json::Value root;
std::ifstream ifs(filename);
const auto success = reader.parse(ifs, root);

if(!success)
{
    const auto errors = reader.getFormattedErrorMessages();
}

For example, CharReader does not have a function getFormattedErrorMessages() - and how should one read from an ifstream using a CharReader.

Understanding the first question - why Reader was deprecated, will likely provide some insight into answering the questions which follow from this.

Can anyone share some explanation on the situation? Thanks
