Summary

This release fixes two bugs in the features introduced in release 3.9.0. The lexer did not accept consecutive comments, and ordered_json lacked some functions from json. All changes are backward-compatible.

🐛 Bug Fixes

• The lexer did not accept input with two or more consecutive comments (e.g. /* one */ /* two */ []). #2330 #2332
• The newly introduced ordered_json container did not implement the complete interface of basic_json which broke existing code when json was replaced by ordered_json, in particular when trying to call ordered_json::parse. #2315 #2319 #2331

🔨 Further Changes

• Install pkg-config file to CMAKE_CURRENT_BINARY_DIR instead of CMAKE_BINARY_DIR #2318
• Make installation directory of pkg-config file depend on CMAKE_INSTALL_LIBDIR. #2314
• Fix -Wimplicit-fallthrough warning. #2333
• Fix name of Homebrew formula in documentation. #2326 #2327
• Fix typo in documentation. #2320

🔥 Deprecated functions

The following functions have been deprecated in earlier versions and will be removed in the next major version (i.e., 4.0.0):

• Function iterator_wrapper are deprecated. Please use the member function items() instead.
• Functions friend std::istream& operator<<(basic_json&, std::istream&) and friend std::ostream& operator>>(const basic_json&, std::ostream&) are deprecated. Please use friend std::istream& operator>>(std::istream&, basic_json&) and friend operator<<(std::ostream&, const basic_json&) instead.
• Passing iterator pairs or pointer/length pairs to parsing functions (basic_json::parse, basic_json::accept, basic_json::sax_parse, basic_json::from_cbor, basic_json::from_msgpack, basic_json::from_ubjson, basic_json::from_bson) via initializer lists is deprecated. Instead, pass two iterators; for instance, call basic_json::from_cbor(ptr, ptr+len) instead of basic_json::from_cbor({ptr, len}).

All deprecations are annotated with HEDLEY_DEPRECATED_FOR to report which function to use instead.
