v2.10.2

What's Changed

• Fix a potential crash in the C extension parser.
• Raise a ParserError on all incomplete unicode escape sequence. This was the behavior until 2.10.0 unadvertently changed it.
• Ensure document snippets that are included in parser errors don't include truncated multibyte characters.
• Ensure parser error snippets are valid UTF-8.
• Fix JSON::GeneratorError#detailed_message on Ruby < 3.2

v2.10.1

What's Changed

• Fix a compatibility issue with MultiJson.dump(obj, pretty: true) by @byroot in #749

v2.10.0

What's Changed

• strict: true now accept symbols as values. Previously they'd only be accepted as hash keys.
• The C extension Parser has been entirely reimplemented from scratch.
• Introduced JSON::Coder as a new API allowing to customize how non native types are serialized in a non-global way.
• Introduced JSON::Fragment to allow assembling cached fragments in a safe way.
• The Java implementation of the generator received many optimizations.
