Bumps alembic from 1.17.2 to 1.18.4.

Release notes

Sourced from alembic's releases.

1.18.4

Released: February 10, 2026

bug

• [bug] [operations] Reverted the behavior of Operations.add_column() that would automatically render the "PRIMARY KEY" keyword inline when a Column with primary_key=True is added. The automatic behavior, added in version 1.18.2, is now opt-in via the new Operations.add_column.inline_primary_key parameter. This change restores the ability to render a PostgreSQL SERIAL column, which is required to be primary_key=True, while not impacting the ability to render a separate primary key constraint. This also provides consistency with the Operations.add_column.inline_references parameter and gives users explicit control over SQL generation.

  To render PRIMARY KEY inline, use the Operations.add_column.inline_primary_key parameter set to True:

  op.add_column( "my_table", Column("id", Integer, primary_key=True), inline_primary_key=True )References: #1232

1.18.3

Released: January 29, 2026

bug

• [bug] [autogenerate] Fixed regression in version 1.18.0 due to #1771 where autogenerate would raise NoReferencedTableError when a foreign key constraint referenced a table that was not part of the initial table load, including tables filtered out by the EnvironmentContext.configure.include_name callable or tables in remote schemas that were not included in the initial reflection run.

  The change in #1771 was a performance optimization that eliminated additional reflection queries for tables that were only referenced by foreign keys but not explicitly included in the main reflection run. However, this optimization inadvertently removed the creation of Table objects for these referenced tables, causing autogenerate to fail when processing foreign key constraints that pointed to them.

  The fix creates placeholder Table objects for foreign key targets
