2.0.0 - 2026-07-16

Breaking changes

• The subkey-derivation option context: replaces salt:, to avoid confusion with scrypt’s salt parameter.

• Subkey derivation now binds the configured cipher and digest names (lowercased) into the HKDF info.

• Nil and empty-string prefixes now yield bare params with no separator.

• Config no longer exposes the alphabet string, it carries the Block58 codec around instead.

• Drop support for Rubies < 3.4.

Other changes

• Raise Epithet::FormatError (< ArgumentError) on invalid wire format

• Improve handling of string encodings

• Additional invariants

• Friendlier errors

• Documentation improvements
