fix #52 (documented new functions)

parent 5e89cb0a
......@@ -33,7 +33,6 @@ As of February 2015, the following updates were made to the library
- *Added*: The class uses **user-defined allocators** which default to `std::allocator`, but can be templated via parameter `Allocator`.
- *Added:* To simplify pretty-printing, the `std::setw` **stream manipulator** has been overloaded to set the desired indentation. Pretty-printing a JSON object `j` is as simple as `std::cout << std::setw(4) << j << '\n'`.
- *Changed*: The type `json::value_t::number` is now called `json::value_t::number_integer` to be more symmetric compared to `json::value_t::number_float`.
- *Removed:* The `key()` and `value()` member functions for object iterators were nonstandard and yielded more problems than benefits. They were removed from the library.
