Breaking Changes

●Issue #1

The default uuid generator has been upgraded to v4 to ensure compatibility with Zod validation. If you rely on the previous UUID format, you must explicitly set the version to '1' in the seed configuration.

Migration Steps

  1. 1
    If using Zod validation for UUIDs, no action is required as the default is now v4.
  2. 2
    To maintain legacy UUID generation, update seed calls to: await seed(db, schema, { version: '1' }).
  3. 3
    To use new features while keeping old UUIDs, use: await seed(db, schema, { version: '2' }) or { version: '3' }.

Release Summary

This release of drizzle-seed introduces column ignoring in refinements, min/max constraints for date/time generators, and automatic Postgres sequence syncing. It also upgrades the default UUID generator to v4 to fix Zod validation errors.
