1.16.3

Released: July 8, 2025

usecase

• [usecase] [commands] Added new pyproject_async template, combining the new pyproject template with the async template. Pull request courtesy Alc-Alc.

  References: #1683

• [usecase] [autogenerate] Add "module" post-write hook. This hook type is almost identical to the console_scripts hook, except it's running python -m black instead of using black's console_script. It is mainly useful for tools without console scripts (e.g. ruff), but has semantics closer to the console_scripts hook in that it finds the ruff module available to the running interpreter instead of finding an executable by path. Pull request courtesy Frazer McLean.

bug

• [bug] [autogenerate] Fixed the rendering of server_default=FetchedValue() to ensure it is preceded by the sa. prefix in the migration script. Pull request courtesy david-fed.

  References: #1633

• [bug] [autogenerate] Fixed autogenerate rendering bug which failed to render foreign key constraints local to a CreateTableOp object if it did not refer to a MetaData collection via a private constructor argument that would not ordinarily be passed in user-defined rewriter recipes, including ones in the Alembic cookbook section of the docs.
