--------------------------

- Wheels are now provided for Python 3.11.


.. _changes_6-4-3:

--------------------------

- Fix a failure when combining data files if the file names contained glob-like
patterns. Thanks, `Michael Krebs and Benjamin Schubert <pull 1405_>`_.

- Fix a messaging failure when combining Windows data files on a different
drive than the current directory, closing `issue 1428`_. Thanks, `Lorenzo
Micò <pull 1430_>`_.

- Fix path calculations when running in the root directory, as you might do in
a Docker container. Thanks `Arthur Rio <pull 1403_>`_.

- Filtering in the HTML report wouldn't work when reloading the index page.
This is now fixed. Thanks, `Marc Legendre <pull 1413_>`_.

- Fix a problem with Cython code measurement, closing `issue 972`_. Thanks,
`Matus Valo <pull 1347_>`_.

.. _changes_6-4-2:

--------------------------

- Updated for a small change in Python 3.11.0 beta 4: modules now start with a
line with line number 0, which is ignored. This line cannot be executed, so
coverage totals were thrown off. This line is now ignored by coverage.py,
but this also means that truly empty modules (like ``__init__.py``) have no
lines in them, rather than one phantom line. Fixes `issue 1419`_.

- Internal debugging data added to sys.modules is now an actual module, to
avoid confusing code that examines everything in sys.modules. Thanks,
`Yilei Yang <pull 1399_>`_.

.. _changes_6-4-1:

--------------------------

- Greatly improved performance on PyPy, and other environments that need the
pure Python trace function. Thanks, Carl Friedrich Bolz-Tereick (`pull
1381`_ and `pull 1388`_). Slightly improved performance when using the C
trace function, as most environments do. Closes `issue 1339`_.

- The conditions for using tomllib from the standard library have been made
more precise, so that 3.11 alphas will continue to work. Closes `issue
1390`_.

.. _changes_64:

------------------------

- A new setting, :ref:`config_run_sigterm`, controls whether a SIGTERM signal
handler is used. In 6.3, the signal handler was always installed, to capture
data at unusual process ends. Unfortunately, this introduced other problems
(see `issue 1310`_). Now the signal handler is only used if you opt-in by
setting ``[run] sigterm = true``.

- Small changes to the HTML report:

- Added links to next and previous file, and more keyboard shortcuts: ``[``
and ``]`` for next file and previous file; ``u`` for up to the index; and
``?`` to open/close the help panel. Thanks, `J. M. F. Tsang
<pull 1364_>`_.

- The time stamp and version are displayed at the top of the report. Thanks,
`Ammar Askar <pull 1354_>`_. Closes `issue 1351`_.

- A new debug option ``debug=sqldata`` adds more detail to ``debug=sql``,
logging all the data being written to the database.

- Previously, running ``coverage report`` (or any of the reporting commands) in
an empty directory would create a .coverage data file. Now they do not,
fixing `issue 1328`_.

- On Python 3.11, the ``[toml]`` extra no longer installs tomli, instead using
tomllib from the standard library. Thanks `Shantanu <pull 1359_>`_.

- In-memory CoverageData objects now properly update(), closing `issue 1323`_.

Closes `issue 1367`_. Some results for generators may have changed.
