Changelog

Sourced from python-slugify's changelog.

9.0.0 — unreleased

• Add keyword-only algorithm='legacy' (permanent default) and explicit algorithm='modern' opt-in, plus CLI --algorithm. Preserve historical default entity ordering, numeric handling, iterator consumption, separator truncation, and public smart_truncate behavior.

• Preserve legacy auto backend selection and two-pass replacement defaults; add explicit backend and replacement_stage keyword-only options and matching CLI flags.

• Add opt-in AnyASCII extra without removing or changing the base text-unidecode dependency.

• Forward CLI --regex-pattern (Jacobo de Vera, #176; report by @​peter-bloomfield, #175).

• Modern mode only: decode entities before transliteration; handle invalid numeric references per match, including surrogate references (#178, #181, #187).

• Modern mode only: materialize replacement rules and stopword iterables consistently; preserve bytes/bytearray UTF-8 input with clear rejection of unsupported types (#183, #190).

• Modern mode only: budget internal tokens using emitted separator widths, support empty separators, and preserve literal word characters that match delimiters. Public smart_truncate remains unchanged (#47, #185, #186).

• Add regression coverage for whitespace, ordinals, backend-specific output, replacement stages, CLI execution, and installed artifacts.

• Move package metadata to pyproject.toml, retain the typed marker and source tests, and remove the unsafe publish/upload/tag shortcut.

• Document output changes, backend license distinctions, compatibility limits, and migration precautions in docs/release-9/migration.md.

• Support Python 3.14.

• Drop support for Python 3.9 and lower.

• Use tox for local test runs and in CI.

• Test the project against both unidecode and text_unidecode.

• Fix type annotation issues identified by mypy.

• Run CI against pull requests.

• Fix package build warnings.
