  • New Maven artifact for seamless Spring Boot 3.x integration
  • Auto-configuration for Spring MVC with HttpMessageConverter support
  • Spring MVC HttpMessageConverters for content negotiation:
    • JsonIoHttpMessageConverter - application/json
    • Json5HttpMessageConverter - application/vnd.json5
    • ToonHttpMessageConverter - application/vnd.toon
  • WebFlux Encoders/Decoders for reactive applications:
    • JsonIoEncoder / JsonIoDecoder - application/json
    • Json5Encoder / Json5Decoder - application/vnd.json5
    • ToonEncoder / ToonDecoder - application/vnd.toon
  • Configuration properties under spring.json-io.*:
    • Write options: pretty-print, show-type-info, skip-null-fields, short-meta-keys, etc.
    • Read options: max-depth, fail-on-unknown-type, allow-nan-and-infinity
    • Integration: jackson-mode (COEXIST, REPLACE, JSON5_ONLY)
  • Customizer interfaces for programmatic configuration:
    • ReadOptionsCustomizer - Customize read behavior
    • WriteOptionsCustomizer - Customize write behavior
  • Jackson coexistence modes:
    • COEXIST (default) - json-io handles JSON5/TOON, Jackson handles JSON
    • REPLACE - json-io handles all formats
  • See Spring Integration Guide for details
• BUILD: Converted to multi-module Maven project structure
  • json-io - Core library (unchanged artifact coordinates)
  • json-io-spring-boot-starter - Spring Boot integration module

4.85.0 - 2025-01-24

• FEATURE: TOON (Token-Oriented Object Notation) output support
  • Added JsonIo.toToon(Object, WriteOptions) - Convert Java objects to TOON format string
  • Added JsonIo.toToon(OutputStream, Object, WriteOptions) - Stream TOON output directly
  • TOON is a compact, human-readable format optimized for LLM token efficiency (~40-50% fewer tokens than JSON)
  • Key TOON characteristics:
    • Indentation-based structure (2 spaces, LF line endings) - no braces/brackets
    • Primitive arrays inline: tags[3]: foo,bar,baz
    • Mixed arrays with hyphen list format
    • Key: value object syntax
    • Minimal quoting (only when necessary per TOON spec)
    • Only 5 escape sequences: \\, \", \n, \r, \t
    • NaN/Infinity → null, -0 → 0 normalization per spec
  • Cycle detection included (silently skips cyclic references)
  • Uses cached reflection via WriteOptions.getDeepDeclaredFields() for efficient field discovery
  • Respects WriteOptions excluded/included field settings
  • See TOON Format Specification for details
  • Comprehensive type support for serialization:
