Release 0.176.0

Compiler support

• Update to Supported compilers
  documentation to reflect the compilers that are currently in continuous integration testing.

• Support for some ancient compilers, in particular g++ 4.8 and 4.9, has been dropped.

• Accepted pr #519 to support build with with llvm-toolset-7 on CentOS 7.

• We (and users) have seen some compilation errors with tests of std::scoped_allocator_adaptor using our sample stateful allocator FreeListAllocator
  in versions of clang predating version 11, and versions of g++ predating version 10. We've therefore excluded these tests when testing with
  the older compilers.

Enhancements

• basic_json now supports using C++ 17 structured binding, so you can write

for (const auto& [key, value] : j.object_range())
{
    std::cout << key << " => " << value << std::endl;
}

• Addressed issue #509 of over allocating memory due to alignment constraints through pr #510

jsonschema extension defect fixes:

• Fixed issue #520 where enabling format validation resulted in a premature abort to validation

• Addressed issue #521 so that jsonschema now supports big integers

Other defect fixes:

• Resolved #518 about CUDA and int128 and float 128

Release 0.175.0

This release contains two breaking changes to recently added
features.

Change to jsonpath::get function

• The return value for jsonpath::get has been changed from a
  pointer to the selected JSON value, or null if not found, to a
  std::pair<Json*,bool>, where the bool component indicates
  whether the get operation succeeded.

Change to new jsonschema classes and functions introduced in 0.174.0:

• The overload of json_schema<Json>::validate that takes a callback
  must now be passed a lambda that returns walk_result::advance or
  walk_result::abort. This supports early exit from validation.

Note that this change does not affect the legacy pre-0.174.0 jsonschema
classes and functions (make_schema, json_validator).

Enhancement to jsonschema library:

• New json_schema member function walk for walking through the schema.

Release 0.174.0

Defect fixes:

• Fixed issue #499 with nan_to_str, inf_to_str and neginf_to_str

Core library enhancements

• New json_options line_splits option that addresses issue #490

jsonpath library enhancements

• New function jsonpath::replace analagous to jsonpointer::replace,
  but for normalized paths.

jsonschema library enhancements

• The jsonschema extension now supports Drafts 4, 6, 2019-09 and 2020-12
  in addition to Draft 07.

  • New function make_json_schema that returns a representation of
    a compiled JSON Schema document.

  • New class validation_message

  • The legacy function make_schema and classes json_validator and
    validation_output remain for backward compatibility, but have been
    deprecated.
