1.13.0

Released: December 1, 2023

[changed] [installation] Alembic 1.13 now supports Python 3.8 and above.

References: #1359

[usecase] [operations] Updated logic introduced in #151 to allow if_exists and if_not_exists on index operations also on SQLAlchemy 1.4 series. Previously this feature was mistakenly requiring the 2.0 series.

References: #1323
[usecase] Replaced python-dateutil with the standard library module zoneinfo. This module was added in Python 3.9, so previous version will been to install the backport of it, available by installing the backports.zoneinfo library. The alembic[tz] option has been updated accordingly.

[bug] [commands] Fixed issue where the alembic check command did not function correctly with upgrade structures that have multiple, top-level elements, as are generated from the "multi-env" environment template. Pull request courtesy Neil Williams.

References: #1234
[bug] [autogenerate] Fixed autogenerate issue where create_table_comment() and drop_table_comment() rendering in a batch table modify would include the "table" and "schema" arguments, which are not accepted in batch as these are already part of the top level block.

References: #1361
[bug] [postgresql] Additional fixes to PostgreSQL expression index compare feature. The compare now correctly accommodates casts and differences in spacing. Added detection logic for operation clauses inside the expression, skipping the compare of these expressions. To accommodate these changes the logic for the comparison of the indexes and unique constraints was moved to the dialect implementation, allowing greater flexibility.
