1.0.0

Breaking Changes

• Using dbos-config.yaml and ConfigFile for library configuration has been deprecated. load_config and ConfigFile have been removed from the public interface. Please use DBOSConfig programmatic configuration instead. Documentation: https://docs.dbos.dev/python/reference/configuration
• get_dbos_database_url has been removed from the public interface. Database URLs should be passed into DBOS through DBOSConfig programmatic configuration. If you need to access the database URL in DBOS Cloud, use the DBOS_DATABASE_URL environment variable, which is automatically set there.
• The DBOS.config getter has been removed from the public interface.
• dbos migrate now requires either a --db-url argument, or a valid DBOS_DATABASE_URL exported in the environment.

New Features

• Queues now support deduplication and prioritization. Documentation here: https://docs.dbos.dev/python/tutorials/queue-tutorial
