Jansson v2.8 Release Notes

Release Date: 2016-08-30 // over 7 years ago

  • 🚀 Released 2016-08-30

    • 🆕 New features:

      • Always preserve insertion order of object items. json_object_iter() and friends, json_object_foreach() and json_dumps() and friends now always work in the insertion order of object items (#293).
      • Add json_object_foreach_safe() macro that allows json_object_del() calls during iteration (#230).
      • Add json_get_alloc_funcs() to allow reading the allocation functions set by json_set_alloc_funcs() (#262, #264).
      • Add json_pack() format specifiers s?, o? and O? for values that can be null (#261, #270).

    • 🐛 Bug fixes:

      • Fix a crash when parsing inputs consisting of very deeply nested arrays or objects (#282, #284).
      • Never convert numbers to integers in the parser when JSON_DECODE_INT_AS_REAL is set. This fixes error messages for overflowing numbers when JSON_DECODE_INT_AS_REAL is set (#212).
      • Fix a use-after-free in json_pack() error handling.
      • Fix subnormal number parsing on mingw32.
      • Handle out-of-memory situations gracefully in the hashtable implementation (#298).

    • 🏗 Build:

      • Fix build with CMake on all versions of Visual Studio up to 2015 (#262, #289).
      • Fix pkgconfig libdir when using CMake (#268).
      • Fix CMake config for static CRT builds on Windows (#206).
      • Fix warnings on LLVM 6.0 targeting iOS arm64 (#208).
      • Add coverlls.io support via Travis for a nice test coverage badge (#211).
      • Don't expect jansson_config.h to be in the compiler's include path (#209).
      • Add a build-time option to set initial hashtable size (#213).
      • Use snprintf and strncpy in place of sprintf and strcpy to silence linker warnings on OpenBSD (#233).

    • 📚 Documentation:

      • Fix various typos in documentation, and a broken link (#258).
      • Add an example program in examples/ (#214, #217).
      • Fix building of documentation man pages (#207).
      • Document the fact that copying objects doesn't preserve the insertion order of keys (#237).

    • ✅ Tests:

      • Don't use the nonstandard FUNCTION macro in tests.
      • Use expr instead of $((...)) in shell scripts for Solaris 10 compatibility.
      • Disable Visual Studio warning C4756 when triggered deliberately in tests (#216).
      • Other minor fixes (#221, #248).

    • Other changes:

      • List all unrecognized object keys when strict unpacking fails (#263).
      • Alter the order of the members of the hashtable_pair struct for easier debugging.
      • Minor performance improvement to json_dump() and friends (#234).
      • Minor style fixes (#255, #257).
