v3.10.0¶

Released on 2021-08-17.

Feature release. All changes are backward-compatible.

• Adds extended diagnostic messages (JSON_DIAGNOSTICS) that prepend a JSON pointer to exception messages to pinpoint the offending value.
• Adds a GDB pretty-printer and a cbor_tag_handler_t store option to keep CBOR tags as binary subtypes.
• Supports containers with non-default-constructible types and parsing from std::byte.
• Adds JSON_NO_IO to exclude the I/O headers and the JSON_HAS_CPP_* macros to override the detected C++ standard.
