Changelog

The complete, itemised changelog lives in the repository: CHANGELOG.md on GitHub. Highlights below.

1.0.0

A ground-up rewrite — see v0.4 vs v1.0 for the story and Migrating for the upgrade path.

Added

  • Mimesis generation engine (replacing Faker), field-name inference, and MRO-based field dispatch.
  • Constraint decoration — max_length, decimal precision, integer ranges, weighted choices, IP protocol, USE_TZ, configurable NULL injection.
  • Foreign-key dependency graph with topological ordering, nullable-cycle breaking, and clear errors for non-nullable cycles.
  • FK strategies — reuse (default), create, mix; OneToOne, self-FK trees, and M2M handling.
  • Row coherence — ordered lifecycle dates, one persona/address per row.
  • Single- and multi-column uniqueness, tracked in memory per target DB.
  • Pre-flight checks — migrations, schema drift, missing tables, backend capabilities.
  • Bulk performance — bulk_create batching, --atomic all|model|none.
  • File/Image/FilePath providers honouring upload_to; --no-files.
  • Rich CLI (checklist, plan tree, progress, summary) and --format json.
  • Python API — seed(), SeedPlan, SeedResult.
  • Reproducibility — --seed.
  • New flags; src-layout packaging with py.typed.

Changed

  • App discovery via apps.get_app_configs() + SEED_APPS / --exclude.
  • --no-of-objects-to-create → --count (deprecated alias kept until 1.1).
  • Minimum versions raised to Python 3.10 and Django 4.0.

Removed

  • Backup / log-entry / current-user features and their global signal receivers.
  • QueryAuthMiddleware, the colorama theme, the duplicated README.rst.
  • The bundled test models that 0.4.x shipped into users' databases.

Fixed

Every correctness bug from the 0.4.2 audit — URL/Slug dispatch, unique-value crashes, FK-cycle recursion, double saves, decimal precision, IP protocol — each with a regression test.
