Bumps alembic from 1.18.2 to 1.18.3.

Release notes

Sourced from alembic's releases.

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 that are not reflected, allowing the autogenerate comparison to proceed without error while maintaining the performance improvement from #1771. When multiple foreign keys reference different columns in the same filtered table, the placeholder table accumulates all necessary columns. These placeholder tables may be visible when using the EnvironmentContext.configure.include_object callable to inspect ForeignKeyConstraint objects; they will have the name, schema and basic column information for the relevant columns present.

    References: #1787

  • [bug] [general] Fixed regression caused by #1669 which requires SQLAlchemy objects to support generic type subscripting; for the older SQLAlchemy 1.4 series, this requires version 1.4.23. Changed the minimum requirements to require version 1.4.23 rather than 1.4.0.

    References: #1788
