0.1.0 - 2026-02-22

Added

  • Added Exdantic.Settings env-based settings loader with:
    • load/2, load!/2, and from_system_env/2
    • field-driven env lookup with env_prefix and env_nested_delimiter
    • field-level absolute env override via extra: %{"env" => "KEY"}
    • test-friendly env: %{} injection (no process env mutation required)
    • loader-level errors: :env_cast, :env_json, :env_key_conflict

Changed

  • Settings decoding and merge behavior now documented and validated by property tests:
    • precedence: input > env > defaults
    • structured types are JSON-only
    • exploded nested values deep-merge over top-level JSON values
    • conservative union env decoding (no union-level scalar coercion probing)
    • no exploded addressing into arrays in v1

0.0.2 - 2025-01-05

Changed

  • Updated CI workflow files to show proper error output
