0.3.0 - 2026-07-27

Added

  • SafeAtom.Plug for casting named, top-level request params against per-field atom whitelists.
  • Rejection handling with default :drop, built-in :halt, and custom two-arity callbacks receiving SafeAtom.Plug.Rejection.
  • Optional {:plug, "~> 1.0"} dependency for applications that use the Plug helper.

0.2.0 - 2026-06-09

Added

  • SafeAtom.Ecto.Enum — parameterized Ecto type with required values: for string-backed atom enum fields; cast, load, and dump use SafeAtom.cast/2 without unsafe atom creation on external binaries.
  • Optional {:ecto, "~> 3.11"} dependency for apps that use the Ecto type.

0.1.0 - 2026-05-19

Added

  • SafeAtom.cast/2 for whitelist-based casting of binaries and atoms without growing the atom table from untrusted input.
  • SafeAtom.cast!/2 and SafeAtom.Error for raising on failed casts.
  • Telemetry event [:safe_atom, :cast, :rejected] when cast/2 returns an error.
