Porting to Python 3.15
----------------------

* :class:`sqlite3.Connection` APIs has been cleaned up.

* All parameters of :func:`sqlite3.connect` except *database* are now keyword-only.
* The first three parameters of methods :meth:`~sqlite3.Connection.create_function`
and :meth:`~sqlite3.Connection.create_aggregate` are now positional-only.
* The first parameter of methods :meth:`~sqlite3.Connection.set_authorizer`,
:meth:`~sqlite3.Connection.set_progress_handler` and
:meth:`~sqlite3.Connection.set_trace_callback` is now positional-only.

(Contributed by Serhiy Storchaka in :gh:`133595`.)

* Private functions promoted to public C APIs:

The |pythoncapi_compat_project| can be used to get most of these new
functions on Python 3.14 and older.

* :data:`resource.RLIM_INFINITY` is now always positive.
Passing a negative integer value that corresponded to its old value
(such as ``-1`` or ``-3``, depending on platform) to
:func:`resource.setrlimit` and :func:`resource.prlimit` is now deprecated.
