v0.2.1 — 2026-05-29

Added

• Windows-1252 and ISO-8859-1 (Latin-1) string encodings, on both read and write.

Changed

• Reading a string in an unsupported encoding now raises instead of silently returning the raw, undecoded bytes (which produced invalid UTF-8 downstream).

v0.2.0 — 2026-05-29

• Write-back. Compile with writer: true (--writer) to generate to_binary/1 and to_file/2, inverting every read operation.
• Automatic length/count controllers: size:/repeat-expr: fields are recomputed from the actual payload on write.
• process: xor with a multi-byte key is now ~5× faster.

v0.1.0 — 2026-02-26

Initial release: a Kaitai Struct compiler and parsing runtime for Elixir.

• mix ksc.compile turns .ksy files into Elixir modules with from_binary/1 and from_file/1.
• Covers integers/floats, bit fields, enums, strings/encodings, user and switch types, repeats, instances, expressions, and process steps.
• Validated against the official Kaitai Struct test suite.
