Release 0.98.2.1

0.98.2.1

Fixes an issue with json variant operator=

0.98.2

json constructor is now templated, so constructors now accept extended types
Following RFC7159, json_parser now accepts any JSON value, removing the constraint that it be an object or array.
The member json_type_traits member functions is, as, and assign have been changed to static functions. if you have implemented your own type specializations, you will also have to change your is, as and assign functions to be static.
Removed json deprecated functions custom_data, set_custom_data, add_custom_data
json_reader member function max_depth has been renamed to max_nesting_depth, the former name is still supported.
json member function resize_array has been renamed to resize, the former name is still supported.
jsoncons supports alternative ways for constructing null, object, and array values.

null:

json a = jsoncons::null_type(); // Using type constructor
json b = json::null_type(); // Using alias
json c(json::null); // From static data member prototype
object:

json a(); // Default is empty object
json b = json::object(); // Using type constructor
json c(json::an_object); // From static data member prototype
array:

json a = json::array(); // Using type constructor
json b = json::make_array(); // Using factory method
json c(json::an_array); // From static data member prototype
Since C++ has possible order issues with static data members, the jsoncons examples and documentation have been changed to consistently use the other ways, and json::null, json::an_object and json::an_array have been, while still usable, deprecated.
