Changelog

Sourced from json's changelog.

2025-05-23 (2.12.2)

• Fix compiler optimization level.

2025-05-23 (2.12.1)

• Fix a potential crash in large negative floating point number generation.
• Fix for JSON.pretty_generate to use passed state object's generate instead of state class as the required parameters aren't available.

2025-05-12 (2.12.0)

• Improve floating point generation to not use scientific notation as much.
• Include line and column in parser errors. Both in the message and as exception attributes.
• Handle non-string hash keys with broken to_s implementations.
• JSON.generate now uses SSE2 (x86) or NEON (arm64) instructions when available to escape strings.

2025-04-25 (2.11.3)

• Fix a regression in JSON.pretty_generate that could cause indentation to be off once some #to_json has been called.

2025-04-24 (2.11.2)

• Add back JSON::PRETTY_STATE_PROTOTYPE. This constant was private API but is used by popular gems like multi_json. It now emits a deprecation warning.

2025-04-24 (2.11.1)

• Add back JSON.restore, JSON.unparse, JSON.fast_unparse and JSON.pretty_unparse. These were deprecated 16 years ago, but never emited warnings, only undocumented, so are still used by a few gems.

2025-04-24 (2.11.0)

• Optimize Integer generation to be ~1.8x faster.
• Optimize Float generation to be ~10x faster.
• Fix JSON.load proc argument to substitute the parsed object with the return value. This better match Marshal.load behavior.
• Deprecate JSON.fast_generate (it's not any faster, so pointless).
• Deprecate JSON.load_default_options.
• Deprecate JSON.unsafe_load_default_options.
• Deprecate JSON.dump_default_options.
• Deprecate Kernel#j
• Deprecate Kernel#jj
• Remove outdated JSON.iconv.
• Remove Class#json_creatable? monkey patch.
• Remove deprecated JSON.restore method.
• Remove deprecated JSON.unparse method.
• Remove deprecated JSON.fast_unparse method.
• Remove deprecated JSON.pretty_unparse method.
• Remove deprecated JSON::UnparserError constant.
