:tags: usecase, oracle

:tickets: 12317, 12341

Added new datatype :class:`_oracle.VECTOR` and accompanying DDL and DQL

support to fully support this type for Oracle Database. This change

includes the base :class:`_oracle.VECTOR` type that adds new type-specific

methods ``l2_distance``, ``cosine_distance``, ``inner_product`` as well as

new parameters ``oracle_vector`` for the :class:`.Index` construct,

allowing vector indexes to be configured, and ``oracle_fetch_approximate``

for the :meth:`.Select.fetch` clause. Pull request courtesy Suraj Shaw.

.. change::

:tags: bug, platform

:tickets: 12405

Adjusted the test suite as well as the ORM's method of scanning classes for

annotations to work under current beta releases of Python 3.14 (currently

3.14.0b1) as part of an ongoing effort to support the production release of

this Python release. Further changes to Python's means of working with

annotations is expected in subsequent beta releases for which SQLAlchemy's

test suite will need further adjustments.

.. change::

:tags: bug, mysql

:tickets: 12488

Fixed regression caused by the DEFAULT rendering changes in version 2.0.40

via :ticket:`12425` where using lowercase ``on update`` in a MySQL server

default would incorrectly apply parenthesis, leading to errors when MySQL

interpreted the rendered DDL. Pull request courtesy Alexander Ruehe.

.. change::

:tags: bug, sqlite

:tickets: 12566

Fixed and added test support for some SQLite SQL functions hardcoded into

the compiler, most notably the ``localtimestamp`` function which rendered

with incorrect internal quoting.

.. change::

:tags: bug, engine

:tickets: 12579

The error message that is emitted when a URL cannot be parsed no longer

includes the URL itself within the error message.

.. change::

:tags: bug, typing

:tickets: 12588

Removed ``__getattr__()`` rule from ``sqlalchemy/__init__.py`` that

appeared to be trying to correct for a previous typographical error in the

imports. This rule interferes with type checking and is removed.

.. change::

:tags: bug, installation

Removed the "license classifier" from setup.cfg for SQLAlchemy 2.0, which

eliminates loud deprecation warnings when building the package. SQLAlchemy

2.1 will use a full :pep:`639` configuration in pyproject.toml while

SQLAlchemy 2.0 remains using ``setup.cfg`` for setup.
