0.4.0 (2026-04-28)
Features
- Add
formats: option for :date and :datetime fields. Tries each
format in order on read; the first to parse successfully wins. Useful
for files that mix date formats (e.g. mostly M/D/YYYY with occasional
YYYY-MM-DD). Mutually exclusive with format:. Writing uses the
first entry in the list. - Add
Module.canonical_string/2 (and Delimit.Schema.canonical_string/3):
generate a stable, deterministic string encoding of a struct based on
its schema. Uses ASCII Unit Separator as the default delimiter. - Add
Module.row_hash/2 (and Delimit.Schema.row_hash/3): compute a
cryptographic hash of a struct's canonical encoding. Defaults to SHA-256
truncated to 16 bytes. - Add
:row_hash derived field type. Declared in the layout, populated
automatically on read with the hash of the row's non-derived fields.
Skipped on write. Supports algorithm: and truncate: options. - Add
:raw_row derived field type. Captures the row as a list of strings
before type coercion. Useful for debugging and audit trails. Skipped
on write.

0.2.0 (2025-05-21)
Fixes
- Do not double skip headers
Other
- Simplified code to eliminate pre-processing
- More appropriate empty row/value detection
- Rely on layout for field mapping, not layout AND header content
