[1.0.0-b4] - 2026-05-30

Added

  • Breaking: GUID TypeDecorator for cross-database UUID support (PostgreSQL UUID type / SQLite TEXT storage)
  • SQLite batch operation support for constraints, indexes, and columns via batch_alter_table()
  • Automatic .env file creation from .env.sample on application startup if .env does not exist
  • .env.sample included in package distribution for ready-to-use configuration reference
  • Migration version counter suffix to prevent duplicate migration versions
  • New database engine detection to distinguish PostgreSQL vs other databases

Fixed

  • Breaking: Migration tracker table rollback_available column conversion from BOOLEAN to INTEGER for PostgreSQL, and compatibility for SQLITE
  • Migration runner now uses run_in_executor() for synchronous DB operations to prevent blocking async event loop
  • Made tracker/backup lazy properties to defer DB initialization
  • Catch ProgrammingError/OperationalError for already-existing resources to make migrations idempotent
  • GUID TypeDecorator now returns UUID instances directly without unnecessary conversion
  • Tracker table now filtered from migration detection to prevent accidental drops
  • Resolved requirements.txt path issue for installed package layout

Removed

  • Removed redundant database type conversion in GUID TypeDecorator

Caution: Users migrating to 1.0.0-b4 will need to drop their existing databases and start afresh. The rollback_available column type changed from BOOLEAN to INTEGER, and GUID column changes require a clean schema migration that cannot be automatically applied to existing data.
