Changelog

0.2.2 - 2026-07-04

• Avoid generated type warnings for guarded cast: callbacks.

0.2.1 - 2026-06-29

• Avoid redundant struct decoding for fields with cast: that already returns the declared struct type.

0.2.0 - 2026-06-29

• Remove unbounded atom: :unsafe decoding; use atom: {:enum, values} or atom: :existing.
• Avoid map decoding for fields with cast: that already produced the declared struct.
• Recognize nested JSONCodec modules during code generation with Code.ensure_compiled/1.

0.1.6 - 2026-06-29

• Add strict: true to reject atom-key maps at JSON boundaries.
• Add cast: field callbacks that run before type decoding.
• Accept existing structs for declared struct fields during decoding.
• Include SKILL.md with consumer guidance in the package.

0.1.5 - 2026-06-15

• Loosen the elixir: requirement from ~> 1.20 to ~> 1.16 so downstream projects on Elixir 1.16–1.19 can resolve json_codec. The codec macros and generated code do not use 1.20+ features.

0.1.4 - 2026-06-13

• Fix defstruct literal defaults so values like %{} remain runtime values instead of escaped AST.

0.1.3 - 2026-06-09

• Add JSONCodec.dump/1 and generated Module.dump/1 helpers that dump codec-owned structs using configured JSON field names (case: :camel and codec(:field, as: ...)).
• Keep to_map/1 unchanged for compatibility.

0.1.2 - 2026-06-09

• Preserve boolean values as JSON booleans when encoding structs or maps with to_map/1.

0.1.1 - 2026-06-07

• Improve README formatting for code identifiers in rendered docs.

0.1.0 - 2026-06-07

Initial release.

• Generate JSON-shaped struct decoders from defstruct and @type t.
• Support aliases, camel-case keys, defaults, nested structs, lists, maps, enums, nullable fields, computed fields, and JSON Schema export.
• Add explicit atom policy with safe existing atoms by default and opt-in atom: :unsafe.
• Add fast_path: :json for optimized Jason-decoded string-key maps with generic fallback.
• Add map value callbacks with values:, values_source:, and decode_values:.
• Include program-facts and Iconify-like benchmarks.
