- update to 1.12.1:
* Fixed regression caused by :ticket:`879` released in 1.7.0
where the ".info" dictionary of ``Table`` would not render in
autogenerate create table statements.
This can be useful for custom create table DDL rendering
schemes so it is restored.
* Improved typing in the
:paramref:`.EnvironmentContext.configure.process_revision_dir
ectives` callable to better indicate that the passed-in type is
:class:`.MigrationScript`, not the :class:`.MigrationOperation`
base class, and added typing to the example at
:ref:`cookbook_no_empty_migrations` to illustrate.
* Repaired :class:`.ExecuteSQLOp` so that it can participate in
"diff" operations; while this object is typically not present
in a reflected operation stream, custom hooks may be adding
this construct where it needs to have the correct
``to_diff_tuple()`` method.
* Improved the ``op.execute()`` method to correctly accept the
* ``Executable`` type that is the same which is used in
SQLAlchemy ``Connection.execute()``.
* Improve typing of the revision parameter in various command
functions.
* Fixed autogen render issue where expressions inside of
indexes for PG need to be double-parenthesized, meaning a
single parens must be present within the generated ``text()``
construct.
* Alembic now accommodates for Sequence and Identity that
support dialect kwargs.
This is a change that will be added to SQLAlchemy v2.1.
