Bumps sqlalchemy from 2.1.2 to 2.1.4.

Release notes

Sourced from sqlalchemy's releases.

2.1.4

Released: October 7, 2026

orm

• [orm] [bug] [regression] Fixed regression caused by #13333 where assigning a MetaData object to the metadata attribute of a mapped Declarative class, in order to place that class's Table in a MetaData collection other than that of the _orm.registry, would emit a warning that the attribute name metadata should be left reserved. The warning is now emitted only when the metadata attribute is assigned to an object other than a MetaData.

  References: #13659

engine

• [engine] [bug] [regression] Fixed regression from the 1.4 series where the DBAPI cursor used for a compiled statement that returns no rows, which includes DDL constructs such as CreateTable and DropTable as well as the SAVEPOINT, ROLLBACK TO SAVEPOINT and RELEASE SAVEPOINT statements emitted by _engine.Connection.begin_nested(), was not closed after execution, and was instead left to be released when garbage collected. The cursor is now closed immediately, as was the case in 1.3 and as is already the case for INSERT, UPDATE, DELETE and _sql.text() statements.

  This change is also backported to: 2.0.55

  References: #13640

• [engine] [bug] Fixed issue in the _engine.Connection.execution_options.logging_token option where setting the value to None or another false value would raise AttributeError if a logging token had not already been established on that _engine.Connection, such as on a newly checked out connection, when the option was set at the _engine.Engine level, or when the token was reset to None more than once. Regression introduced in 2.0.30 as part of #11210.

  This change is also backported to: 2.0.55

  References: #13641

• [engine] [bug] [regression] Fixed regression where iterating a Result directly would create reference cycles that prevented the Result along with the DBAPI
