Breaking Changes

●Issue #1

PG transactions switched from class properties back to class methods. Code relying on transaction methods being accessible as properties must be updated to call them as methods (e.g., `tx.method()` instead of `tx.property`).

Migration Steps

  1. 1
    If you were accessing PG transaction methods as properties, update the calls to use them as methods.
  2. 2
    When generating SQLite migrations, if you encounter conflict detection errors and wish to proceed, use the `--ignore-conflicts` flag with `drizzle-kit generate` or `drizzle-kit check`.

Release Summary

This release introduces significant improvements to SQLite migration handling, including conflict detection and better tree merging, alongside fixes for custom column codecs and PG transaction implementation details.
