v3.9.1 Changes
August 06, 2020π Release date: 2020-08-06
SHA-256: 7804b38146921d03374549c9e2a5e3acda097814c43caf2b96a0278e58df26e0 (json.hpp), 6bea5877b1541d353bd77bdfbdb2696333ae5ed8f9e8cc22df657192218cad91 (include.zip)Summary
This release fixes two bugs in the features introduced in release 3.9.0. The lexer did not accept consecutive comments , and
ordered_jsonlacked some functions fromjson. All changes are backward-compatible.π π° Note you can support this project via GitHub sponsors or PayPal.
π± π Bug Fixes
- The lexer did not accept input with two or more consecutive comments (e.g.
/* one */ /* two */ []). #2330 #2332 - The newly introduced
ordered_jsoncontainer did not implement the complete interface ofbasic_jsonwhich broke existing code whenjsonwas replaced byordered_json, in particular when trying to callordered_json::parse. #2315 #2319 #2331
π± π¨ Further Changes
- Install pkg-config file to
CMAKE_CURRENT_BINARY_DIRinstead ofCMAKE_BINARY_DIR#2318 - Make installation directory of pkg-config file depend on
CMAKE_INSTALL_LIBDIR. #2314 - π Fix
-Wimplicit-fallthroughwarning. #2333 - π Fix name of Homebrew formula in documentation. #2326 #2327
- π Fix typo in documentation. #2320
π± π₯ Deprecated functions
π 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_wrapperare deprecated. Please use the member functionitems()instead. - Functions
friend std::istream& operator<<(basic_json&, std::istream&)andfriend std::ostream& operator>>(const basic_json&, std::ostream&)are deprecated. Please usefriend std::istream& operator>>(std::istream&, basic_json&)andfriend operator<<(std::ostream&, const basic_json&)instead. - π 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 the elements individually without braces.
π All deprecations are annotated with
HEDLEY_DEPRECATED_FORto report which function to use instead. - The lexer did not accept input with two or more consecutive comments (e.g.

Project bad_json_parsers tested how JSON parser libraries react on deeply nested inputs. It turns out that this library segfaulted at a certain nesting depth. This bug was fixed with this release. Now the parsing is only bounded by the available memory. All changes are backward-compatible.
π± π Bug Fixes
- π Fixed a bug that lead to stack overflow for deeply nested JSON values (objects, array) by changing the implementation of the destructor from a recursive to an iterative approach. #832, #1419, #1835
