38.0.4

~~~~~~~~~~~~~~~~~~~

* Fixed compilation when using LibreSSL 3.6.0.
* Fixed error when using ``py2app`` to build an application with a
``cryptography`` dependency.

.. _v38-0-3:

38.0.3

~~~~~~~~~~~~~~~~~~~

* Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 3.0.7,
which resolves *CVE-2022-3602* and *CVE-2022-3786*.

.. _v38-0-2:

38.0.2

~~~~~~~~~~~~~~~~~~~~~~~~~~~~

.. attention::

 This release was subsequently yanked from PyPI due to a regression in OpenSSL.

* Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 3.0.6.


.. _v38-0-1:

38.0.1

~~~~~~~~~~~~~~~~~~~

* Fixed parsing TLVs in ASN.1 with length greater than 65535 bytes (typically
seen in large CRLs).

.. _v38-0-0:

38.0.0

~~~~~~~~~~~~~~~~~~~

* Final deprecation of OpenSSL 1.1.0. The next release of ``cryptography``
will drop support.
* We no longer ship ``manylinux2010`` wheels. Users should upgrade to the
latest ``pip`` to ensure this doesn't cause issues downloading wheels on
their platform. We now ship ``manylinux_2_28`` wheels for users on new
enough platforms.
* Updated the minimum supported Rust version (MSRV) to 1.48.0, from 1.41.0.
Users with the latest ``pip`` will typically get a wheel and not need Rust
installed, but check :doc:`/installation` for documentation on installing a
newer ``rustc`` if required.
* :meth:`~cryptography.fernet.Fernet.decrypt` and related methods now accept
both ``str`` and ``bytes`` tokens.
* Parsing ``CertificateSigningRequest`` restores the behavior of enforcing
that the ``Extension`` ``critical`` field must be correctly encoded DER. See
`the issue <https://github.com/pyca/cryptography/issues/6368>`_ for complete
details.
* Added two new OpenSSL functions to the bindings to support an upcoming
``pyOpenSSL`` release.
* When parsing :class:`~cryptography.x509.CertificateRevocationList` and
:class:`~cryptography.x509.CertificateSigningRequest` values, it is now
enforced that the ``version`` value in the input must be valid according to
the rules of :rfc:`2986` and :rfc:`5280`.
* Using MD5 or SHA1 in :class:`~cryptography.x509.CertificateBuilder` and
other X.509 builders is deprecated and support will be removed in the next
version.
* Added additional APIs to
:class:`~cryptography.x509.certificate_transparency.SignedCertificateTimestamp`, including
:attr:`~cryptography.x509.certificate_transparency.SignedCertificateTimestamp.signature_hash_algorithm`,
:attr:`~cryptography.x509.certificate_transparency.SignedCertificateTimestamp.signature_algorithm`,
:attr:`~cryptography.x509.certificate_transparency.SignedCertificateTimestamp.signature`, and
:attr:`~cryptography.x509.certificate_transparency.SignedCertificateTimestamp.extension_bytes`.
* Added :attr:`~cryptography.x509.Certificate.tbs_precertificate_bytes`, allowing
users to access the to-be-signed pre-certificate data needed for signed
certificate timestamp verification.
* :class:`~cryptography.hazmat.primitives.kdf.kbkdf.KBKDFHMAC` and
:class:`~cryptography.hazmat.primitives.kdf.kbkdf.KBKDFCMAC` now support
:attr:`~cryptography.hazmat.primitives.kdf.kbkdf.CounterLocation.MiddleFixed`
counter location.
* Fixed :rfc:`4514` name parsing to reverse the order of the RDNs according
to the section 2.1 of the RFC, affecting method
:meth:`~cryptography.x509.Name.from_rfc4514_string`.
* It is now possible to customize some aspects of encryption when serializing
private keys, using
:meth:`~cryptography.hazmat.primitives.serialization.PrivateFormat.encryption_builder`.
* Removed several legacy symbols from our OpenSSL bindings. Users of pyOpenSSL
versions older than 22.0 will need to upgrade.
* Added
:class:`~cryptography.hazmat.primitives.ciphers.algorithms.AES128` and
:class:`~cryptography.hazmat.primitives.ciphers.algorithms.AES256` classes.
These classes do not replace
:class:`~cryptography.hazmat.primitives.ciphers.algorithms.AES` (which
allows all AES key lengths), but are intended for applications where
developers want to be explicit about key length.

.. _v37-0-4:

37.0.4

~~~~~~~~~~~~~~~~~~~

* Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 3.0.5.

.. _v37-0-3:

37.0.3

~~~~~~~~~~~~~~~~~~~~~~~~~~~~

.. attention::

 This release was subsequently yanked from PyPI due to a regression in OpenSSL.

* Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 3.0.4.

.. _v37-0-2:

37.0.2

~~~~~~~~~~~~~~~~~~~

* Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 3.0.3.
* Added a constant needed for an upcoming pyOpenSSL release.

.. _v37-0-1:

37.0.1

~~~~~~~~~~~~~~~~~~~

* Fixed an issue where parsing an encrypted private key with the public
loader functions would hang waiting for console input on OpenSSL 3.0.x rather
than raising an error.
* Restored some legacy symbols for older ``pyOpenSSL`` users. These will be
removed again in the future, so ``pyOpenSSL`` users should still upgrade
to the latest version of that package when they upgrade ``cryptography``.

.. _v37-0-0:

37.0.0

~~~~~~~~~~~~~~~~~~~

* Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 3.0.2.
* **BACKWARDS INCOMPATIBLE:** Dropped support for LibreSSL 2.9.x and 3.0.x.
The new minimum LibreSSL version is 3.1+.
* **BACKWARDS INCOMPATIBLE:** Removed ``signer`` and ``verifier`` methods
from the public key and private key classes. These methods were originally
deprecated in version 2.0, but had an extended deprecation timeline due
to usage. Any remaining users should transition to ``sign`` and ``verify``.
* Deprecated OpenSSL 1.1.0 support. OpenSSL 1.1.0 is no longer supported by
the OpenSSL project. The next release of ``cryptography`` will be the last
to support compiling with OpenSSL 1.1.0.
* Deprecated Python 3.6 support. Python 3.6 is no longer supported by the
Python core team. Support for Python 3.6 will be removed in a future
``cryptography`` release.
* Deprecated the current minimum supported Rust version (MSRV) of 1.41.0.
In the next release we will raise MSRV to 1.48.0. Users with the latest
``pip`` will typically get a wheel and not need Rust installed, but check
:doc:`/installation` for documentation on installing a newer ``rustc`` if
required.
* Deprecated
:class:`~cryptography.hazmat.primitives.ciphers.algorithms.CAST5`,
:class:`~cryptography.hazmat.primitives.ciphers.algorithms.SEED`,
:class:`~cryptography.hazmat.primitives.ciphers.algorithms.IDEA`, and
:class:`~cryptography.hazmat.primitives.ciphers.algorithms.Blowfish` because
they are legacy algorithms with extremely low usage. These will be removed
in a future version of ``cryptography``.
* Added limited support for distinguished names containing a bit string.
* We now ship ``universal2`` wheels on macOS, which contain both ``arm64``
and ``x86_64`` architectures. Users on macOS should upgrade to the latest
``pip`` to ensure they can use this wheel, although we will continue to
ship ``x86_64`` specific wheels for now to ease the transition.
* This will be the final release for which we ship ``manylinux2010`` wheels.
Going forward the minimum supported ``manylinux`` ABI for our wheels will
be ``manylinux2014``. The vast majority of users will continue to receive
``manylinux`` wheels provided they have an up to date ``pip``. For PyPy
wheels this release already requires ``manylinux2014`` for compatibility
with binaries distributed by upstream.
* Added support for multiple
:class:`~cryptography.x509.ocsp.OCSPSingleResponse` in a
:class:`~cryptography.x509.ocsp.OCSPResponse`.
* Restored support for signing certificates and other structures in
:doc:`/x509/index` with SHA3 hash algorithms.
* :class:`~cryptography.hazmat.primitives.ciphers.algorithms.TripleDES` is
disabled in FIPS mode.
* Added support for serialization of PKCS12 CA friendly names/aliases in
:func:`~cryptography.hazmat.primitives.serialization.pkcs12.serialize_key_and_certificates`
* Added support for 12-15 byte (96 to 120 bit) nonces to
:class:`~cryptography.hazmat.primitives.ciphers.aead.AESOCB3`. This class
previously supported only 12 byte (96 bit).
* Added support for
:class:`~cryptography.hazmat.primitives.ciphers.aead.AESSIV` when using
OpenSSL 3.0.0+.
* Added support for serializing PKCS7 structures from a list of
certificates with
:class:`~cryptography.hazmat.primitives.serialization.pkcs7.serialize_certificates`.
* Added support for parsing :rfc:`4514` strings with
:meth:`~cryptography.x509.Name.from_rfc4514_string`.
* Added :attr:`~cryptography.hazmat.primitives.asymmetric.padding.PSS.AUTO` to
:class:`~cryptography.hazmat.primitives.asymmetric.padding.PSS`. This can
be used to verify a signature where the salt length is not already known.
* Added :attr:`~cryptography.hazmat.primitives.asymmetric.padding.PSS.DIGEST_LENGTH`
to :class:`~cryptography.hazmat.primitives.asymmetric.padding.PSS`. This
constant will set the salt length to the same length as the ``PSS`` hash
algorithm.
* Added support for loading RSA-PSS key types with
:func:`~cryptography.hazmat.primitives.serialization.load_pem_private_key`
and
:func:`~cryptography.hazmat.primitives.serialization.load_der_private_key`.
This functionality is limited to OpenSSL 1.1.1e+ and loads the key as a
normal RSA private key, discarding the PSS constraint information.

.. _v36-0-2:

36.0.2

~~~~~~~~~~~~~~~~~~~

* Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 1.1.1n.

.. _v36-0-1:

36.0.1

~~~~~~~~~~~~~~~~~~~

* Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 1.1.1m.

.. _v36-0-0:

36.0.0

~~~~~~~~~~~~~~~~~~~

* **FINAL DEPRECATION** Support for ``verifier`` and ``signer`` on our
asymmetric key classes was deprecated in version 2.0. These functions had an
extended deprecation due to usage, however the next version of
``cryptography`` will drop support. Users should migrate to ``sign`` and
``verify``.
* The entire :doc:`/x509/index` layer is now written in Rust. This allows
alternate asymmetric key implementations that can support cloud key
management services or hardware security modules provided they implement
the necessary interface (for example:
:class:`~cryptography.hazmat.primitives.asymmetric.ec.EllipticCurvePrivateKey`).
* :ref:`Deprecated the backend argument<faq-missing-backend>` for all
functions.
* Added support for
:class:`~cryptography.hazmat.primitives.ciphers.aead.AESOCB3`.
* Added support for iterating over arbitrary request
:attr:`~cryptography.x509.CertificateSigningRequest.attributes`.
* Deprecated the ``get_attribute_for_oid`` method on
:class:`~cryptography.x509.CertificateSigningRequest` in favor of
:meth:`~cryptography.x509.Attributes.get_attribute_for_oid` on the new
:class:`~cryptography.x509.Attributes` object.
* Fixed handling of PEM files to allow loading when certificate and key are
in the same file.
* Fixed parsing of :class:`~cryptography.x509.CertificatePolicies` extensions
containing legacy ``BMPString`` values in their ``explicitText``.
* Allow parsing of negative serial numbers in certificates. Negative serial
numbers are prohibited by :rfc:`5280` so a deprecation warning will be
raised whenever they are encountered. A future version of ``cryptography``
will drop support for parsing them.
* Added support for parsing PKCS12 files with friendly names for all
certificates with
:func:`~cryptography.hazmat.primitives.serialization.pkcs12.load_pkcs12`,
which will return an object of type
:class:`~cryptography.hazmat.primitives.serialization.pkcs12.PKCS12KeyAndCertificates`.
* :meth:`~cryptography.x509.Name.rfc4514_string` and related methods now have
an optional ``attr_name_overrides`` parameter to supply custom OID to name
mappings, which can be used to match vendor-specific extensions.
* **BACKWARDS INCOMPATIBLE:** Reverted the nonstandard formatting of
email address fields as ``E`` in
:meth:`~cryptography.x509.Name.rfc4514_string` methods from version 35.0.

The previous behavior can be restored with:
``name.rfc4514_string({NameOID.EMAIL_ADDRESS: "E"})``
* Allow
:class:`~cryptography.hazmat.primitives.asymmetric.x25519.X25519PublicKey`
and
:class:`~cryptography.hazmat.primitives.asymmetric.x448.X448PublicKey` to
be used as public keys when parsing certificates or creating them with
:class:`~cryptography.x509.CertificateBuilder`. These key types must be
signed with a different signing algorithm as ``X25519`` and ``X448`` do
not support signing.
* Extension values can now be serialized to a DER byte string by calling
:func:`~cryptography.x509.ExtensionType.public_bytes`.
* Added experimental support for compiling against BoringSSL. As BoringSSL
does not commit to a stable API, ``cryptography`` tests against the
latest commit only. Please note that several features are not available
when building against BoringSSL.
* Parsing ``CertificateSigningRequest`` from DER and PEM now, for a limited
time period, allows the ``Extension`` ``critical`` field to be incorrectly
encoded. See `the issue <https://github.com/pyca/cryptography/issues/6368>`_
for complete details. This will be reverted in a future ``cryptography``
release.
* When :class:`~cryptography.x509.OCSPNonce` are parsed and generated their
value is now correctly wrapped in an ASN.1 ``OCTET STRING``. This conforms
to :rfc:`6960` but conflicts with the original behavior specified in
:rfc:`2560`. For a temporary period for backwards compatibility, we will
also parse values that are encoded as specified in :rfc:`2560` but this
behavior will be removed in a future release.

.. _v35-0-0:

35.0.0

~~~~~~~~~~~~~~~~~~~

* Changed the :ref:`version scheme <api-stability:versioning>`. This will
result in us incrementing the major version more frequently, but does not
change our existing backwards compatibility policy.
* **BACKWARDS INCOMPATIBLE:** The :doc:`/x509/index` PEM parsers now require
that the PEM string passed have PEM delimiters of the correct type. For
example, parsing a private key PEM concatenated with a certificate PEM will
no longer be accepted by the PEM certificate parser.
* **BACKWARDS INCOMPATIBLE:** The X.509 certificate parser no longer allows
negative serial numbers. :rfc:`5280` has always prohibited these.
* **BACKWARDS INCOMPATIBLE:** Additional forms of invalid ASN.1 found during
:doc:`/x509/index` parsing will raise an error on initial parse rather than
when the malformed field is accessed.
* Rust is now required for building ``cryptography``, the
``CRYPTOGRAPHY_DONT_BUILD_RUST`` environment variable is no longer
respected.
* Parsers for :doc:`/x509/index` no longer use OpenSSL and have been
rewritten in Rust. This should be backwards compatible (modulo the items
listed above) and improve both security and performance.
* Added support for OpenSSL 3.0.0 as a compilation target.
* Added support for
:class:`~cryptography.hazmat.primitives.hashes.SM3` and
:class:`~cryptography.hazmat.primitives.ciphers.algorithms.SM4`,
when using OpenSSL 1.1.1. These algorithms are provided for compatibility
in regions where they may be required, and are not generally recommended.
* We now ship ``manylinux_2_24`` and ``musllinux_1_1`` wheels, in addition to
our ``manylinux2010`` and ``manylinux2014`` wheels. Users on distributions
like Alpine Linux should ensure they upgrade to the latest ``pip`` to
correctly receive wheels.
* Added ``rfc4514_attribute_name`` attribute to :attr:`x509.NameAttribute
<cryptography.x509.NameAttribute.rfc4514_attribute_name>`.
* Added :class:`~cryptography.hazmat.primitives.kdf.kbkdf.KBKDFCMAC`.

0.4.6

* https://github.com/tartley/colorama/pull/139 Add alternative to 'init()',
 called 'just_fix_windows_console'. This fixes many longstanding problems
 with 'init', such as working incorrectly on modern Windows terminals, and
 wonkiness when init gets called multiple times. The intention is that it
 just makes all Windows terminals treat ANSI the same way as other terminals
 do. Many thanks the njsmith for fixing our messes. 
* https://github.com/tartley/colorama/pull/352 Support Windows 10's ANSI/VT
 console. This didn't exist when Colorama was created, and avoiding us
 causing havok there is long overdue. Thanks to segeviner for the initial
 approach, and to njsmith for getting it merged.
* https://github.com/tartley/colorama/pull/338 Internal overhaul of package
 metadata declaration, which abolishes our use of the now heavily
 discouraged setuptools (and hence setup.py, setup.cfg and MANIFEST.in), in
 favor of hatchling (and hence pyproject.toml), generously contributed by
 ofek (author of hatchling). This includes dropping support Python3.5 and
 3.6, which are EOL, and were already dropped from setuptools, so this
 should not affect our users.
* https://github.com/tartley/colorama/pull/353 Attention to detail award to
 LqdBcnAtWork for a spelling fix in demo06

0.4.5

* Catch a racy ValueError that could occur on exit.
* Create README-hacking.md, for Colorama contributors.
* Tweak some README unicode characters that don't render correctly on PyPI.
* Fix some tests that were failing on some operating systems.
* Add support for Python 3.9.
* Add support for PyPy3.
* Add support for pickling with the ``dill`` module.

6.5.0

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

- The JSON report now includes details of which branches were taken, and which
are missing for each file. Thanks, Christoph Blessing (`pull 1438`_). Closes
`issue 1425`_.

- Starting with coverage.py 6.2, ``class`` statements were marked as a branch.
This wasn't right, and has been reverted, fixing `issue 1449`_. Note this
will very slightly reduce your coverage total if you are measuring branch
coverage.

- Packaging is now compliant with `PEP 517`_, closing `issue 1395`_.

- A new debug option ``--debug=pathmap`` shows details of the remapping of
paths that happens during combine due to the ``[paths]`` setting.

- Fix an internal problem with caching of invalid Python parsing. Found by
OSS-Fuzz, fixing their `bug 50381`_.

.. _changes_6-4-3:

6.4.3

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

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

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

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

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

- Fix a problem with Cython code measurement (`pull 1347`_, fixing `issue
972`_).  Thanks, Matus Valo.

.. _changes_6-4-2:

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 cannnot 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:

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:

6.4

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

- 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 timestamp 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`_.

6.3.3

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

- Fix: Coverage.py now builds successfully on CPython 3.11 (3.11.0b1) again.
Closes `issue 1367`_.  Some results for generators may have changed.

.. _issue 1367: https://github.com/nedbat/coveragepy/issues/1367


.. _changes_632:

6.3.2

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

- Fix: adapt to pypy3.9's decorator tracing behavior.  It now traces function
decorators like CPython 3.8: both the -line and the def-line are traced.
Fixes `issue 1326`_.

- Debug: added ``pybehave`` to the list of :ref:`coverage debug <cmd_debug>`
and :ref:`cmd_run_debug` options.

- Fix: show an intelligible error message if ``--concurrency=multiprocessing``
is used without a configuration file.  Closes `issue 1320`_.

.. _changes_631:

6.3.1

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

- Fix: deadlocks could occur when terminating processes.  Some of these
deadlocks (described in `issue 1310`_) are now fixed.

- Fix: a signal handler was being set from multiple threads, causing an error:
"ValueError: signal only works in main thread".  This is now fixed, closing
`issue 1312`_.

- Fix: ``--precision`` on the command-line was being ignored while considering
``--fail-under``.  This is now fixed, thanks to
`Marcelo Trylesinski <pull 1317_>`_.

- Fix: releases no longer provide 3.11.0-alpha wheels. Coverage.py uses CPython
internal fields which are moving during the alpha phase. Fixes `issue 1316`_.

.. _changes_63:

6.3

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

- Feature: Added the ``lcov`` command to generate reports in LCOV format.
Thanks, `Bradley Burns <pull 1289_>`_. Closes issues `587 <issue 587_>`_
and `626 <issue 626_>`_.

- Feature: the coverage data file can now be specified on the command line with
the ``--data-file`` option in any command that reads or writes data.  This is
in addition to the existing ``COVERAGE_FILE`` environment variable.  Closes
`issue 624`_. Thanks, `Nikita Bloshchanevich <pull 1304_>`_.

- Feature: coverage measurement data will now be written when a SIGTERM signal
is received by the process.  This includes
:meth:`Process.terminate <python:multiprocessing.Process.terminate>`,
and other ways to terminate a process.  Currently this is only on Linux and
Mac; Windows is not supported.  Fixes `issue 1307`_.

- Dropped support for Python 3.6, which reached end-of-life on 2021-12-23.

- Updated Python 3.11 support to 3.11.0a4, fixing `issue 1294`_.

- Fix: the coverage data file is now created in a more robust way, to avoid
problems when multiple processes are trying to write data at once. Fixes
issues `1303 <issue 1303_>`_ and `883 <issue 883_>`_.

- Fix: a .gitignore file will only be written into the HTML report output
directory if the directory is empty.  This should prevent certain unfortunate
accidents of writing the file where it is not wanted.

- Releases now have MacOS arm64 wheels for Apple Silicon, fixing `issue 1288`_.

6.2

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

- Feature: Now the ``--concurrency`` setting can now have a list of values, so
that threads and another lightweight threading package can be measured
together, such as ``--concurrency=gevent,thread``.  Closes `issue 1012`_ and
`issue 1082`_.

- Fix: A module specified as the ``source`` setting is imported during startup,
before the user program imports it.  This could cause problems if the rest of
the program isn't ready yet.  For example, `issue 1203`_ describes a Django
setting that is accessed before settings have been configured.  Now the early
import is wrapped in a try/except so errors then don't stop execution.

- Fix: A colon in a decorator expression would cause an exclusion to end too
early, preventing the exclusion of the decorated function. This is now fixed.

- Fix: The HTML report now will not overwrite a .gitignore file that already
exists in the HTML output directory (follow-on for `issue 1244`_).

- API: The exceptions raised by Coverage.py have been specialized, to provide
finer-grained catching of exceptions by third-party code.

- API: Using ``suffix=False`` when constructing a Coverage object with
multiprocessing wouldn't suppress the data file suffix (`issue 989`_).  This
is now fixed.

- Debug: The ``coverage debug data`` command will now sniff out combinable data
files, and report on all of them.

- Debug: The ``coverage debug`` command used to accept a number of topics at a
time, and show all of them, though this was never documented.  This no longer
works, to allow for command-line options in the future.

6.1.2

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

- Python 3.11 is supported (tested with 3.11.0a2).  One still-open issue has to
do with `exits through with-statements <issue 1270_>`_.

- Fix: When remapping file paths through the ``[paths]`` setting while
combining, the ``[run] relative_files`` setting was ignored, resulting in
absolute paths for remapped file names (`issue 1147`_).  This is now fixed.

- Fix: Complex conditionals over excluded lines could have incorrectly reported
a missing branch (`issue 1271`_). This is now fixed.

- Fix: More exceptions are now handled when trying to parse source files for
reporting.  Problems that used to terminate coverage.py can now be handled
with ``[report] ignore_errors``.  This helps with plugins failing to read
files (`django_coverage_plugin issue 78`_).

- Fix: Removed another vestige of jQuery from the source tarball
(`issue 840`_).

- Fix: Added a default value for a new-to-6.x argument of an internal class.
This unsupported class is being used by coveralls (`issue 1273`_). Although
I'd rather not "fix" unsupported interfaces, it's actually nicer with a
default value.

6.1.1

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

- Fix: The sticky header on the HTML report didn't work unless you had branch
coverage enabled. This is now fixed: the sticky header works for everyone.
(Do people still use coverage without branch measurement!? j/k)

- Fix: When using explicitly declared namespace packages, the "already imported
a file that will be measured" warning would be issued (`issue 888`_).  This
is now fixed.

.. _issue 888: https://github.com/nedbat/coveragepy/issues/888


.. _changes_61:

6.1

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

- Deprecated: The ``annotate`` command and the ``Coverage.annotate`` function
will be removed in a future version, unless people let me know that they are
using it.  Instead, the ``html`` command gives better-looking (and more
accurate) output, and the ``report -m`` command will tell you line numbers of
missing lines.  Please get in touch if you have a reason to use ``annotate``
over those better options: nednedbatchelder.com.

- Feature: Coverage now sets an environment variable, ``COVERAGE_RUN`` when
running your code with the ``coverage run`` command.  The value is not
important, and may change in the future.  Closes `issue 553`_.

- Feature: The HTML report pages for Python source files now have a sticky
header so the file name and controls are always visible.

- Feature: The ``xml`` and ``json`` commands now describe what they wrote
where.

- Feature: The ``html``, ``combine``, ``xml``, and ``json`` commands all accept
a ``-q/--quiet`` option to suppress the messages they write to stdout about
what they are doing (`issue 1254`_).

- Feature: The ``html`` command writes a ``.gitignore`` file into the HTML
output directory, to prevent the report from being committed to git.  If you
want to commit it, you will need to delete that file.  Closes `issue 1244`_.

- Feature: Added support for PyPy 3.8.

- Fix: More generated code is now excluded from measurement.  Code such as
`attrs`_ boilerplate, or doctest code, was being measured though the
synthetic line numbers meant they were never reported.  Once Cython was
involved though, the generated .so files were parsed as Python, raising
syntax errors, as reported in `issue 1160`_.  This is now fixed.

- Fix: When sorting human-readable names, numeric components are sorted
correctly: file10.py will appear after file9.py.  This applies to file names,
module names, environment variables, and test contexts.

- Performance: Branch coverage measurement is faster, though you might only
notice on code that is executed many times, such as long-running loops.

- Build: jQuery is no longer used or vendored (`issue 840`_ and `issue 1118`_).
Huge thanks to Nils Kattenbeck (septatrix) for the conversion to vanilla
JavaScript in `pull request 1248`_.

6.0.2

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

- Namespace packages being measured weren't properly handled by the new code
that ignores third-party packages. If the namespace package was installed, it
was ignored as a third-party package.  That problem (`issue 1231`_) is now
fixed.

- Packages named as "source packages" (with ``source``, or ``source_pkgs``, or
pytest-cov's ``--cov``) might have been only partially measured.  Their
top-level statements could be marked as unexecuted, because they were
imported by coverage.py before measurement began (`issue 1232`_).  This is
now fixed, but the package will be imported twice, once by coverage.py, then
again by your test suite.  This could cause problems if importing the package
has side effects.

- The :meth:`.CoverageData.contexts_by_lineno` method was documented to return
a dict, but was returning a defaultdict.  Now it returns a plain dict.  It
also no longer returns negative numbered keys.

6.0.1

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

- In 6.0, the coverage.py exceptions moved from coverage.misc to
coverage.exceptions. These exceptions are not part of the public supported
API, CoverageException is. But a number of other third-party packages were
importing the exceptions from coverage.misc, so they are now available from
there again (`issue 1226`_).

- Changed an internal detail of how tomli is imported, so that tomli can use
coverage.py for their own test suite (`issue 1228`_).

- Defend against an obscure possibility under code obfuscation, where a
function can have an argument called "self", but no local named "self"
(`pull request 1210`_).  Thanks, Ben Carlsson.

6.0

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

- The ``coverage html`` command now prints a message indicating where the HTML
report was written.  Fixes `issue 1195`_.

- The ``coverage combine`` command now prints messages indicating each data
file being combined.  Fixes `issue 1105`_.

- The HTML report now includes a sentence about skipped files due to
``skip_covered`` or ``skip_empty`` settings.  Fixes `issue 1163`_.

- Unrecognized options in the configuration file are no longer errors. They are
now warnings, to ease the use of coverage across versions.  Fixes `issue
1035`_.

- Fix handling of exceptions through context managers in Python 3.10. A missing
exception is no longer considered a missing branch from the with statement.
Fixes `issue 1205`_.

- Fix another rarer instance of "Error binding parameter 0 - probably
unsupported type." (`issue 1010`_).

- Creating a directory for the coverage data file now is safer against
conflicts when two coverage runs happen simultaneously (`pull 1220`_).
Thanks, Clément Pit-Claudel.

6.0b1

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

- Dropped support for Python 2.7, PyPy 2, and Python 3.5.

- Added support for the Python 3.10 ``match/case`` syntax.

- Data collection is now thread-safe.  There may have been rare instances of
exceptions raised in multi-threaded programs.

- Plugins (like the `Django coverage plugin`_) were generating "Already
imported a file that will be measured" warnings about Django itself.  These
have been fixed, closing `issue 1150`_.

- Warnings generated by coverage.py are now real Python warnings.

- Using ``--fail-under=100`` with coverage near 100% could result in the
self-contradictory message :code:`total of 100 is less than fail-under=100`.
This bug (`issue 1168`_) is now fixed.

- The ``COVERAGE_DEBUG_FILE`` environment variable now accepts ``stdout`` and
``stderr`` to write to those destinations.

- TOML parsing now uses the `tomli`_ library.

- Some minor changes to usually invisible details of the HTML report:

- Use a modern hash algorithm when fingerprinting, for high-security
 environments (`issue 1189`_).  When generating the HTML report, we save the
 hash of the data, to avoid regenerating an unchanged HTML page. We used to
 use MD5 to generate the hash, and now use SHA-3-256.  This was never a
 security concern, but security scanners would notice the MD5 algorithm and
 raise a false alarm.

- Change how report file names are generated, to avoid leading underscores
 (`issue 1167`_), to avoid rare file name collisions (`issue 584`_), and to
 avoid file names becoming too long (`issue 580`_).

5.6b1

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

Note: 5.6 final was never released. These changes are part of 6.0.

- Third-party packages are now ignored in coverage reporting.  This solves a
few problems:

- Coverage will no longer report about other people's code (`issue 876`_).
 This is true even when using ``--source=.`` with a venv in the current
 directory.

- Coverage will no longer generate "Already imported a file that will be
 measured" warnings about coverage itself (`issue 905`_).

- The HTML report uses j/k to move up and down among the highlighted chunks of
code.  They used to highlight the current chunk, but 5.0 broke that behavior.
Now the highlighting is working again.

- The JSON report now includes ``percent_covered_display``, a string with the
total percentage, rounded to the same number of decimal places as the other
reports' totals.

.. _changes_55:

5.5

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

- ``coverage combine`` has a new option, ``--keep`` to keep the original data
files after combining them.  The default is still to delete the files after
they have been combined.  This was requested in `issue 1108`_ and implemented
in `pull request 1110`_.  Thanks, Éric Larivière.

- When reporting missing branches in ``coverage report``, branches aren't
reported that jump to missing lines.  This adds to the long-standing behavior
of not reporting branches from missing lines.  Now branches are only reported
if both the source and destination lines are executed.  Closes both `issue
1065`_ and `issue 955`_.

- Minor improvements to the HTML report:

- The state of the line visibility selector buttons is saved in local storage
 so you don't have to fiddle with them so often, fixing `issue 1123`_.

- It has a little more room for line numbers so that 4-digit numbers work
 well, fixing `issue 1124`_.

- Improved the error message when combining line and branch data, so that users
will be more likely to understand what's happening, closing `issue 803`_.

5.4

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

- The text report produced by ``coverage report`` now always outputs a TOTAL
line, even if only one Python file is reported.  This makes regex parsing
of the output easier.  Thanks, Judson Neer.  This had been requested a number
of times (`issue 1086`_, `issue 922`_, `issue 732`_).

- The ``skip_covered`` and ``skip_empty`` settings in the configuration file
can now be specified in the ``[html]`` section, so that text reports and HTML
reports can use separate settings.  The HTML report will still use the
``[report]`` settings if there isn't a value in the ``[html]`` section.
Closes `issue 1090`_.

- Combining files on Windows across drives now works properly, fixing `issue
577`_.  Thanks, `Valentin Lab <pr1080_>`_.

- Fix an obscure warning from deep in the _decimal module, as reported in
`issue 1084`_.

- Update to support Python 3.10 alphas in progress, including `PEP 626: Precise
line numbers for debugging and other tools <pep626_>`_.

5.3.1

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

- When using ``--source`` on a large source tree, v5.x was slower than previous
versions.  This performance regression is now fixed, closing `issue 1037`_.

- Mysterious SQLite errors can happen on PyPy, as reported in `issue 1010`_. An
immediate retry seems to fix the problem, although it is an unsatisfying
solution.

- The HTML report now saves the sort order in a more widely supported way,
fixing `issue 986`_.  Thanks, Sebastián Ramírez (`pull request 1066`_).

- The HTML report pages now have a :ref:`Sleepy Snake <sleepy>` favicon.

- Wheels are now provided for manylinux2010, and for PyPy3 (pp36 and pp37).

- Continuous integration has moved from Travis and AppVeyor to GitHub Actions.
