Introduction
------------

Url is constructed from ``str``:

.. code-block:: pycon

   >>> from yarl import URL
   >>> url = URL('https://www.python.org/~guido?arg=1#frag')
   >>> url
   URL('https://www.python.org/~guido?arg=1#frag')

All url parts: *scheme*, *user*, *password*, *host*, *port*, *path*,
*query* and *fragment* are accessible by properties:

.. code-block:: pycon

   >>> url.scheme
   'https'
   >>> url.host
   'www.python.org'
   >>> url.path
   '/~guido'
   >>> url.query_string
   'arg=1'
   >>> url.query
   <MultiDictProxy('arg': '1')>
   >>> url.fragment
   'frag'

All url manipulations produce a new url object:

.. code-block:: pycon

   >>> url = URL('https://www.python.org')
   >>> url / 'foo' / 'bar'
   URL('https://www.python.org/foo/bar')
   >>> url / 'foo' % {'bar': 'baz'}
   URL('https://www.python.org/foo?bar=baz')

Strings passed to constructor and modification methods are
automatically encoded giving canonical representation as result:

.. code-block:: pycon

   >>> url = URL('https://www.python.org/шлях')
   >>> url
   URL('https://www.python.org/%D1%88%D0%BB%D1%8F%D1%85')

Regular properties are *percent-decoded*, use ``raw_`` versions for
getting *encoded* strings:

.. code-block:: pycon

   >>> url.path
   '/шлях'

   >>> url.raw_path
   '/%D1%88%D0%BB%D1%8F%D1%85'

Human readable representation of URL is available as ``.human_repr()``:

.. code-block:: pycon

   >>> url.human_repr()
   'https://www.python.org/шлях'

For full documentation please read https://yarl.aio-libs.org.


Installation
------------

::

   $ pip install yarl

The library is Python 3 only!

PyPI contains binary wheels for Linux, Windows and MacOS.  If you want to install
``yarl`` on another operating system where wheels are not provided,
the tarball will be used to compile the library from
the source code. It requires a C compiler and and Python headers installed.

To skip the compilation you must explicitly opt-in by using a PEP 517
configuration setting ``pure-python``, or setting the ``YARL_NO_EXTENSIONS``
environment variable to a non-empty value, e.g.:

.. code-block:: console

   $ pip install yarl --config-settings=pure-python=false

Please note that the pure-Python (uncompiled) version is much slower. However,
PyPy always uses a pure-Python implementation, and, as such, it is unaffected
by this variable.

Dependencies
------------

YARL requires multidict_ and propcache_ libraries.


API documentation
------------------

The documentation is located at https://yarl.aio-libs.org.


Why isn't boolean supported by the URL query API?
-------------------------------------------------

There is no standard for boolean representation of boolean values.

Some systems prefer ``true``/``false``, others like ``yes``/``no``, ``on``/``off``,
``Y``/``N``, ``1``/``0``, etc.

``yarl`` cannot make an unambiguous decision on how to serialize ``bool`` values because
it is specific to how the end-user's application is built and would be different for
different apps.  The library doesn't accept booleans in the API; a user should convert
bools into strings using own preferred translation protocol.


Comparison with other URL libraries
------------------------------------

* furl (https://pypi.python.org/pypi/furl)

  The library has rich functionality but the ``furl`` object is mutable.

  I'm afraid to pass this object into foreign code: who knows if the
  code will modify my url in a terrible way while I just want to send URL
  with handy helpers for accessing URL properties.

  ``furl`` has other non-obvious tricky things but the main objection
  is mutability.

* URLObject (https://pypi.python.org/pypi/URLObject)

  URLObject is immutable, that's pretty good.

  Every URL change generates a new URL object.

  But the library doesn't do any decode/encode transformations leaving the
  end user to cope with these gory details.

v1.24.2
=======

*(2026-05-19)*


Contributor-facing changes
--------------------------

- Switched the aarch64 and armv7l wheel builds to GitHub's native ARM
  runners. The aarch64 wheels now build without QEMU emulation, and
  armv7l runs on aarch64 hosts so its 32-bit ARM execution is far
  cheaper than the previous aarch64-on-x86_64 path
  -- by `@bdraco <https://github.com/sponsors/bdraco>`__.

  *Related issues and pull requests on GitHub:*
  `#1724 <https://github.com/aio-libs/yarl/issues/1724>`__.

- Restored per-runner native arches in the Windows wheel matrix on tag
  releases. The previous ``CIBW_ARCHS_WINDOWS=AMD64 ARM64`` setting made
  both ``windows-latest`` and ``windows-11-arm`` cross-compile the other
  arch, producing two artifacts with identically-named wheels whose
  bytes differed; the deploy job's ``download-artifact ... merge-multiple``
  step tore those writes together, yielding a wheel that PyPI rejected
  with ``400 Invalid distribution file. ZIP archive not accepted:
  Mis-matched data size`` during the 1.24.0 and 1.24.1 releases
  -- by `@bdraco <https://github.com/sponsors/bdraco>`__.

  `#1725 <https://github.com/aio-libs/yarl/issues/1725>`__.

v1.24.1
=======

*(2026-05-19)*


Contributor-facing changes
--------------------------

- Allowed re-running the deploy job after a partial release failure: the
  ``Make Release`` step now skips when the GitHub Release already exists,
  and the PyPI publish step uses ``skip-existing`` so dists that were
  already uploaded on a prior attempt do not break the retry
  -- by `@bdraco <https://github.com/sponsors/bdraco>`__.

Bug fixes
---------

- Delayed importing pydantic until it's needed to avoid increased import time -- by `@Dreamsorcerer <https://github.com/sponsors/Dreamsorcerer>`__.

  *Related issues and pull requests on GitHub:*
  `#1607 <https://github.com/aio-libs/yarl/issues/1607>`__, `#1702 <https://github.com/aio-libs/yarl/issues/1702>`__.

- Fixed pickling of ``~yarl.URL`` on Python 3.15, where ``SplitResult``
  gained a ``__getstate__`` that requires attributes set by ``__init__``.
  ``__getstate__`` now returns the raw 5-tuple instead of a ``SplitResult``
  built via ``tuple.__new__``, so pickling no longer touches ``SplitResult``
  serialization at all. Pickles produced by older yarl releases (which embed
  a ``SplitResult``) continue to load unchanged
  -- by `@befeleme <https://github.com/sponsors/befeleme>`__.

  *Related issues and pull requests on GitHub:*
  `#1632 <https://github.com/aio-libs/yarl/issues/1632>`__, `#1642 <https://github.com/aio-libs/yarl/issues/1642>`__, `#1687 <https://github.com/aio-libs/yarl/issues/1687>`__.

- Fixed a parsing issue where URLs containing text before an opening bracket
  in the host component (e.g. ``http://127.0.0.1[aa::ff]``) were silently accepted
  instead of being rejected as strictly invalid per RFC 3986
  -- by `@rodrigobnogueira <https://github.com/sponsors/rodrigobnogueira>`__.

  *Related issues and pull requests on GitHub:*
  `#1654 <https://github.com/aio-libs/yarl/issues/1654>`__.

- Raise ``ValueError`` when a URL's authority component contains a
  backslash, which is not a valid character per ``3986``
  -- by `@rodrigobnogueira <https://github.com/sponsors/rodrigobnogueira>`__.

  *Related issues and pull requests on GitHub:*
  `#1659 <https://github.com/aio-libs/yarl/issues/1659>`__.

- Fixed a host-confusion parsing bug where URLs containing multiple bracket
  characters in the host component (e.g. ``http://[:localhost[]].google:80``)
  were silently parsed as an unintended host. Both ``split_url()`` and
  ``split_netloc()`` now raise ``ValueError`` when more than one ``[`` or
  ``]`` is found in the authority, or when ``[`` does not appear at the start of
  the host subcomponent, in compliance with ``3986`` -- by
  `@rodrigobnogueira <https://github.com/sponsors/rodrigobnogueira>`__.

  *Related issues and pull requests on GitHub:*
  `#1661 <https://github.com/aio-libs/yarl/issues/1661>`__.

- Fixed a parser/serializer inconsistency where percent-encoded characters in
  the scheme portion of a URL (e.g. ``ht%74p://...``) were decoded by the
  requoter, causing ``str()`` and ``yarl.URL.human_repr()`` to emit an
  absolute URL with a scheme and host while the parsed properties
  (``~yarl.URL.scheme``, ``~yarl.URL.host``, ``~yarl.URL.absolute``)
  reported a relative, hostless URL. The fix preserves the percent-encoding of
  the colon (``%3A``) in relative paths whenever decoding it would materialize a
  URL scheme -- by `@rodrigobnogueira <https://github.com/sponsors/rodrigobnogueira>`__.

  *Related issues and pull requests on GitHub:*
  `#1669 <https://github.com/aio-libs/yarl/issues/1669>`__.

- Fixed a parsing issue where URLs containing text after the closing bracket
  of an IP-literal host (e.g. ``http://[::1]allowed.example:1/``) were silently
  accepted and normalized to the bracketed IP address (``http://[::1]:1/``),
  dropping the trailing suffix and changing the effective host identity.
  Per RFC 3986, after the closing ``]`` only ``:`` followed by a port number or
  end-of-authority is valid
  -- by `@rodrigobnogueira <https://github.com/sponsors/rodrigobnogueira>`__.

  *Related issues and pull requests on GitHub:*
  `#1626 <https://github.com/aio-libs/yarl/issues/1626>`__.


Removals and backward incompatible breaking changes
---------------------------------------------------

  *Related issues and pull requests on GitHub:*
  `#1667 <https://github.com/aio-libs/yarl/issues/1667>`__.


Improved documentation
----------------------

- Added a note in the ``yarl.URL.with_query()`` documentation explaining
  that types implementing ``__int__`` (e.g. ``~uuid.UUID``) are
  converted to integers, and advising users to cast to ``str`` when the
  human-readable representation is needed -- by `@r266-tech <https://github.com/sponsors/r266-tech>`__.

  `#1638 <https://github.com/aio-libs/yarl/issues/1638>`__, `#1645 <https://github.com/aio-libs/yarl/issues/1645>`__.


Contributor-facing changes
--------------------------

- Resolved a ruff ``ISC004`` violation in the PEP 517 build backend so the
  pre-commit ``ruff-check`` hook passes again
  -- by `@bdraco <https://github.com/sponsors/bdraco>`__.

  *Related issues and pull requests on GitHub:*
  `#1674 <https://github.com/aio-libs/yarl/issues/1674>`__.

- Renamed the ``actions/checkout`` ``depth`` input to ``fetch-depth`` in the
  reusable codspeed workflow so the actionlint pre-commit hook passes and the
  intended shallow clone actually takes effect
  -- by `@bdraco <https://github.com/sponsors/bdraco>`__.

  *Related issues and pull requests on GitHub:*
  `#1676 <https://github.com/aio-libs/yarl/issues/1676>`__.

- Bumped the pinned ``pyupgrade`` pre-commit hook to ``v3.21.2`` so it stops
  crashing on Python 3.14, which made ``tokenize.cookie_re`` bytes-only
  -- by `@bdraco <https://github.com/sponsors/bdraco>`__.

  *Related issues and pull requests on GitHub:*
  `#1677 <https://github.com/aio-libs/yarl/issues/1677>`__.

- The type preciseness coverage report generated by `MyPy
  <https://mypy-lang.org>`__ is now uploaded to `Coveralls
  <https://coveralls.io/github/aio-libs/yarl>`__ and
  will not be included in the `Codecov views
  <https://app.codecov.io/gh/aio-libs/yarl>`__ going forward
  -- by `@webknjaz <https://github.com/sponsors/webknjaz>`__.

  *Related issues and pull requests on GitHub:*
  `#1680 <https://github.com/aio-libs/yarl/issues/1680>`__.

- Raised the per-matrix-cell timeout of the CI ``Test`` job from
  5 to 10 minutes to prevent false failures on slower runners
  -- by `@aiolibsbot <https://github.com/sponsors/aiolibsbot>`__.

  *Related issues and pull requests on GitHub:*
  `#1683 <https://github.com/aio-libs/yarl/issues/1683>`__.

- Added an ``AGENTS.md`` orientation file at the repository root,
  covering the pull request template, ``CHANGES/`` news fragment
  conventions, draft-PR workflow, and the Cython quoter layout, so
  LLM contributors land changes that match project style
  -- by `@bdraco <https://github.com/sponsors/bdraco>`__.

  *Related issues and pull requests on GitHub:*
  `#1685 <https://github.com/aio-libs/yarl/issues/1685>`__.

- Documented in ``AGENTS.md`` that the coverage gate also
  applies to test code, so unreachable defensive ``raise`` guards
  and one-sided cleanup branches in tests will fail CI
  -- by `@bdraco <https://github.com/sponsors/bdraco>`__.

  *Related issues and pull requests on GitHub:*
  `#1689 <https://github.com/aio-libs/yarl/issues/1689>`__.

- Shrunk the CI wheel-build matrix on pull requests and non-tag pushes by
  restricting ``CIBW_ARCHS_MACOS`` to ``arm64``, ``CIBW_ARCHS_WINDOWS`` to
  ``AMD64``, and skipping the ``windows-11-arm`` runner -- the test matrix only
  exercises those architectures, so the previously-built ``x86_64`` macOS and
  ``ARM64`` Windows wheels were never installed. Tag releases still build the
  full architecture set
  -- by `@aiolibsbot <https://github.com/sponsors/aiolibsbot>`__.

  *Related issues and pull requests on GitHub:*
  `#1692 <https://github.com/aio-libs/yarl/issues/1692>`__.

- Documented the docs spell check (``make doc-spelling``) in
  ``AGENTS.md`` as a pre-push gate, mirroring
  `aio-libs/multidict#1345
  <https://github.com/aio-libs/multidict/pull/1345>`__. The
  spell checker reads every ``CHANGES/*.rst`` fragment as part
  of the docs build, so an unknown technical word in a news
  fragment fails CI before a human sees the PR
  -- by `@bdraco <https://github.com/sponsors/bdraco>`__.

  *Related issues and pull requests on GitHub:*
  `#1693 <https://github.com/aio-libs/yarl/issues/1693>`__.

- Added a ``CLAUDE.md`` at the repository root that imports
  ``AGENTS.md`` via Claude Code's ``@``-syntax, so the
  project's LLM contributor rules load automatically when
  working in Claude Code
  -- by `@bdraco <https://github.com/sponsors/bdraco>`__.

  *Related issues and pull requests on GitHub:*
  `#1696 <https://github.com/aio-libs/yarl/issues/1696>`__.

- Enforced top-level imports across ``yarl`` and ``tests`` via the ruff
  ``PLC0415`` rule, wired through a new ``ruff-check`` pre-commit hook.
  Function-scoped imports must now opt in with ``# noqa: PLC0415`` plus
  a comment explaining the import-time reason. Dropped the ``yesqa``
  hook, which could not recognize ruff-only codes and stripped the new
  ``noqa`` comments as stale; a wider migration off flake8 onto ruff
  will follow separately
  -- by `@bdraco <https://github.com/sponsors/bdraco>`__.

  *Related issues and pull requests on GitHub:*
  `#1697 <https://github.com/aio-libs/yarl/issues/1697>`__.

- Migrated the main tree from standalone ``black`` and ``isort``
  pre-commit hooks to ``ruff format`` and the ruff ``I`` lint rule,
  sharing the existing ``[tool.ruff]`` config in ``pyproject.toml``.
  ``ruff-check`` now runs with ``--fix`` so import-order fixes apply
  on commit, and the orphan ``[isort]`` block in ``setup.cfg`` was
  removed. The ``packaging/pep517_backend/`` subtree keeps its own
  ``.ruff.toml`` and is unaffected
  -- by `@bdraco <https://github.com/sponsors/bdraco>`__.

  *Related issues and pull requests on GitHub:*
  `#1698 <https://github.com/aio-libs/yarl/issues/1698>`__.

- Switched the ``cibuildwheel`` build frontend to ``build[uv]`` so
  that ``uv`` provisions every build and test virtual environment
  in the wheel matrix. Test-dependency installation in particular
  drops from a multi-second ``pip install`` per ABI to a roughly
  sub-second ``uv`` resolve
  -- by `@bdraco <https://github.com/sponsors/bdraco>`__.

  *Related issues and pull requests on GitHub:*
  `#1699 <https://github.com/aio-libs/yarl/issues/1699>`__.

- Restructured the root ``CLAUDE.md`` to import contributor
  context from a shared ``aio-libs`` layer
  (``~/.claude/aio-libs/context.md``), a project-specific layer
  (``~/.claude/aio-libs/yarl/context.md``), the in-tree
  ``AGENTS.md``, and an optional per-checkout
  ``CLAUDE.local.md`` override (added to ``.gitignore``),
  so shared ``aio-libs`` guidance can live outside the repository
  while project rules continue to load automatically in Claude
  Code -- by `@aiolibsbot <https://github.com/sponsors/aiolibsbot>`__.

  *Related issues and pull requests on GitHub:*
  `#1700 <https://github.com/aio-libs/yarl/issues/1700>`__, `#1701 <https://github.com/aio-libs/yarl/issues/1701>`__.

- Switched CI/CD to ``tox-dev/workflow``'s ``reusable-tox.yml``
  driven by an in-tree ``tox.ini``. The ``build``,
  ``metadata-validation`` and ``lint`` (``pre-commit``,
  ``spellcheck-docs``, ``build-docs``) jobs all run through the
  reusable workflow; MyPy coverage uploads to Coveralls from a
  ``post-tox-job`` hook
  -- by `@bdraco <https://github.com/sponsors/bdraco>`__.

  *Related issues and pull requests on GitHub:*
  `#1711 <https://github.com/aio-libs/yarl/issues/1711>`__.

- Switched the CI ``test`` job from ``actions/setup-python`` to
  ``astral-sh/setup-uv`` with ``uv pip install``. Pre-release
  interpreters skip the wheel cache so each run resolves freshly
  against the current snapshot
  -- by `@bdraco <https://github.com/sponsors/bdraco>`__.

  *Related issues and pull requests on GitHub:*
  `#1715 <https://github.com/aio-libs/yarl/issues/1715>`__.

- Switched the ``Aiohttp`` workflow that runs the aiohttp test
  suite against the in-tree yarl checkout from
  ``actions/setup-python`` to ``astral-sh/setup-uv`` with ``uv
  pip install``
  -- by `@bdraco <https://github.com/sponsors/bdraco>`__.

  *Related issues and pull requests on GitHub:*
  `#1716 <https://github.com/aio-libs/yarl/issues/1716>`__.

- Switched the ``Aiohttp`` workflow's ``make .develop`` step to
  install aiohttp's dev env through ``uv pip`` by passing
  ``PIP="uv pip"``
  -- by `@bdraco <https://github.com/sponsors/bdraco>`__.

1.23.0
======

*(2025-12-16)*


Features
--------

- Added support for ``pydantic``, the ``~yarl.URL`` could be used as a
  field type in ``pydantic`` models seamlessly.

  *Related issues and pull requests on GitHub:*
  `#1607 <https://github.com/aio-libs/yarl/issues/1607>`__.


Packaging updates and notes for downstreams
-------------------------------------------

- The CI has been set up to notify Codecov about upload completion
  -- by `@webknjaz <https://github.com/sponsors/webknjaz>`__.

  With this, Codecov no longer needs to guess whether it received all
  the intended coverage reports or not.

  *Related issues and pull requests on GitHub:*
  `#1577 <https://github.com/aio-libs/yarl/issues/1577>`__.

- The in-tree build backend allows the end-users appending
  ``CFLAGS`` and ``LDFLAGS`` by setting respective environment
  variables externally.

  It additionally sets up default compiler flags to perform
  building with maximum optimization in release mode. This
  makes the resulting artifacts shipped to PyPI smaller.

  When line tracing is requested, the compiler and linker
  flags are configured to include as much information as
  possible for debugging and coverage tracking. The
  development builds are therefore smaller.

  -- by `@webknjaz <https://github.com/sponsors/webknjaz>`__

  *Related issues and pull requests on GitHub:*
  `#1586 <https://github.com/aio-libs/yarl/issues/1586>`__.

- The `PEP 517 <https://peps.python.org/pep-517>`__ build backend now supports a new config
  setting for controlling whether to build the project in-tree
  or in a temporary directory. It only affects wheels and is
  set up to build in a temporary directory by default. It does
  not affect editable wheel builds — they will keep being
  built in-tree regardless.

  .. code-block:: console

     $ python -m build \

  `#1590 <https://github.com/aio-libs/yarl/issues/1590>`__.

- Starting this version, when building the wheels is happening
  in an automatically created temporary directory, the build
  backend makes an effort to normalize the respective file
  system path to a deterministic source checkout directory.

  -- by `@webknjaz <https://github.com/sponsors/webknjaz>`__

  It does so by injecting the ``-ffile-prefix-map`` compiler
  option into the ``CFLAGS`` environment variable as suggested
  by known `reproducible build practices
  <https://reproducible-builds.org/docs/build-path/>`__.

  The effect is that downstreams will get more reproducible
  build results.

  `#1550 <https://github.com/aio-libs/yarl/issues/1550>`__.

- The in-tree build backend allows the end-users appending
  ``CFLAGS`` and ``LDFLAGS`` by setting respective environment
  variables externally.

  It additionally sets up default compiler flags to perform
  building with maximum optimization in release mode. This
  makes the resulting artifacts shipped to PyPI smaller.

  When line tracing is requested, the compiler and linker
  flags are configured to include as much information as
  possible for debugging and coverage tracking. The
  development builds are therefore smaller.

  release builds -- by `@webknjaz <https://github.com/sponsors/webknjaz>`__.

  When the release workflow is triggered, the pre-built wheels
  ready to hit PyPI are being tested. Otherwise, the job
  builds the project from source, while the rest of the
  workflow uses debug builds for line tracing and coverage
  collection.

- Made Cython line tracing opt-in via the ``with-cython-tracing`` build config setting -- by `@bdraco <https://github.com/sponsors/bdraco>`__.

  Previously, line tracing was enabled by default in ``pyproject.toml``, which caused build issues for some users and made wheels nearly twice as slow.
  Now line tracing is only enabled when explicitly requested via ``pip install . --config-setting=with-cython-tracing=true`` or by setting the ``YARL_CYTHON_TRACING`` environment variable.

Packaging updates and notes for downstreams
-------------------------------------------

- Switched to using the ``propcache`` package for property caching
  -- by `@bdraco <https://github.com/sponsors/bdraco>`__.

  The ``propcache`` package is derived from the property caching
  code in ``yarl`` and has been broken out to avoid maintaining it for multiple
  projects.

1.9.10
======

*(2024-09-04)*


Bug fixes
---------

- ``URL.join()()`` has been changed to match
  ``3986`` and align with
  ``/ operation()`` and ``URL.joinpath()()``
  when joining URLs with empty segments.
  Previously ``urllib.parse.urljoin`` was used,
  which has known issues with empty segments
  (`python/cpython#84774 <https://github.com/python/cpython/issues/84774>`_).

  Due to the semantics of ``URL.join()()``, joining an
  URL with scheme requires making it relative, prefixing with ``./``.

  .. code-block:: pycon

     >>> URL("https://web.archive.org/web/").join(URL("./https://github.com/aio-libs/yarl"))
     URL('https://web.archive.org/web/https://github.com/aio-libs/yarl')


  Empty segments are honored in the base as well as the joined part.

1.9.7

Removals and backward incompatible breaking changes
---------------------------------------------------

- Removed support ``3986#section-3.2.3`` port normalization when the scheme is not one of ``http``, ``https``, ``wss``, or ``ws`` -- by `@bdraco <https://github.com/sponsors/bdraco>`__.

  Support for port normalization was recently added in `#1033 <https://github.com/aio-libs/yarl/issues/1033>`__ and contained code that would do blocking I/O if the scheme was not one of the four listed above. The code has been removed because this library is intended to be safe for usage with ``asyncio``.

Bug fixes
---------

- Reverted ``3986`` compatible ``URL.join()()`` honoring empty segments which was introduced in `#1039 <https://github.com/aio-libs/yarl/issues/1039>`__.

  This change introduced a regression handling query string parameters with joined URLs. The change was reverted to maintain compatibility with the previous behavior.

1.9.5
=====

*(2024-08-30)*


Bug fixes
---------

- Joining URLs with empty segments has been changed
  to match ``3986``.

  Previously empty segments would be removed from path,
  breaking use-cases such as

  .. code-block:: python

     URL("https://web.archive.org/web/") / "https://github.com/"

  Now ``/ operation()`` and ``URL.joinpath()()``
  keep empty segments, but do not introduce new empty segments.
  e.g.

  .. code-block:: python

     URL("https://example.org/") / ""

  does not introduce an empty segment.

  *Related issues and pull requests on GitHub:*
  `#1026 <https://github.com/aio-libs/yarl/issues/1026>`__.

- The default protocol ports of well-known URI schemes are now taken into account
  during the normalization of the URL string representation in accordance with
  ``3986#section-3.2.3``.

  Specified ports are removed from the ``str`` representation of a ``~yarl.URL``
  if the port matches the scheme's default port -- by `@commonism <https://github.com/sponsors/commonism>`__.

Packaging updates and notes for downstreams
-------------------------------------------

- A flaw in the logic for copying the project directory into a
  temporary folder that led to infinite recursion when ``TMPDIR``
  was set to a project subdirectory path. This was happening in Fedora
  and its downstream due to the use of `pyproject-rpm-macros
  <https://src.fedoraproject.org/rpms/pyproject-rpm-macros>`__. It was
  only reproducible with ``pip wheel`` and was not affecting the
  ``pyproject-build`` users.

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

- ``port``, ``scheme``, and ``raw_host`` are now ``cached_property`` -- by `@bdraco <https://github.com/sponsors/bdraco>`__.

  ``aiohttp`` accesses these properties quite often, which cause ``urllib`` to build the ``_hostinfo`` property every time. ``port``, ``scheme``, and ``raw_host`` are now cached properties, which will improve performance.

1.9.4 (2023-12-06)
==================

Bug fixes
---------

- Started raising ``TypeError`` when a string value is passed into
  ``yarl.URL.build()`` as the ``port`` argument  -- by `@commonism <https://github.com/sponsors/commonism>`__.

  Previously the empty string as port would create malformed URLs when rendered as string representations. (`#883 <https://github.com/aio-libs/yarl/issues/883>`__)


Packaging updates and notes for downstreams
-------------------------------------------

- The leading ``--`` has been dropped from the `PEP 517 <https://peps.python.org/pep-517>`__ in-tree build
  backend config setting names. ``--pure-python`` is now just ``pure-python``
  -- by `@webknjaz <https://github.com/sponsors/webknjaz>`__.

  The usage now looks as follows:

  .. code-block:: console

      $ python -m build \
          --config-setting=pure-python=true \
          --config-setting=with-cython-tracing=true

  (`#963 <https://github.com/aio-libs/yarl/issues/963>`__)


Contributor-facing changes
--------------------------

- A step-by-step ``Release Guide`` guide has
  been added, describing how to release *yarl* -- by `@webknjaz <https://github.com/sponsors/webknjaz>`__.

  This is primarily targeting maintainers. (`#960 <https://github.com/aio-libs/yarl/issues/960>`__)
- Coverage collection has been implemented for the Cython modules
  -- by `@webknjaz <https://github.com/sponsors/webknjaz>`__.

  It will also be reported to Codecov from any non-release CI jobs.

  To measure coverage in a development environment, *yarl* can be
  installed in editable mode:

  .. code-block:: console

      $ python -Im pip install -e .

  Editable install produces C-files required for the Cython coverage
  plugin to map the measurements back to the PYX-files.

  `#961 <https://github.com/aio-libs/yarl/issues/961>`__

- It is now possible to request line tracing in Cython builds using the
  ``with-cython-tracing`` `PEP 517 <https://peps.python.org/pep-517>`__ config setting
  -- `@webknjaz <https://github.com/sponsors/webknjaz>`__.

  This can be used in CI and development environment to measure coverage
  on Cython modules, but is not normally useful to the end-users or
  downstream packagers.

  Here's a usage example:

  .. code-block:: console

      $ python -Im pip install . --config-settings=with-cython-tracing=true

  For editable installs, this setting is on by default. Otherwise, it's
  off unless requested explicitly.

  The following produces C-files required for the Cython coverage
  plugin to map the measurements back to the PYX-files:

  .. code-block:: console

      $ python -Im pip install -e .

  Alternatively, the ``YARL_CYTHON_TRACING=1`` environment variable
  can be set to do the same as the `PEP 517 <https://peps.python.org/pep-517>`__ config setting.

1.9.3 (2023-11-20)
==================

Bug fixes
---------

- Stopped dropping trailing slashes in ``yarl.URL.joinpath()`` -- by `@gmacon <https://github.com/sponsors/gmacon>`__. (`#862 <https://github.com/aio-libs/yarl/issues/862>`__, `#866 <https://github.com/aio-libs/yarl/issues/866>`__)
- Started accepting string subclasses in ``yarl.URL.__truediv__()`` operations (``URL / segment``) -- by `@mjpieters <https://github.com/sponsors/mjpieters>`__. (`#871 <https://github.com/aio-libs/yarl/issues/871>`__, `#884 <https://github.com/aio-libs/yarl/issues/884>`__)
- Fixed the human representation of URLs with square brackets in usernames and passwords -- by `@mjpieters <https://github.com/sponsors/mjpieters>`__. (`#876 <https://github.com/aio-libs/yarl/issues/876>`__, `#882 <https://github.com/aio-libs/yarl/issues/882>`__)
- Updated type hints to include ``URL.missing_port()``, ``URL.__bytes__()``
  and the ``encoding`` argument to ``yarl.URL.joinpath()``
  -- by `@mjpieters <https://github.com/sponsors/mjpieters>`__. (`#891 <https://github.com/aio-libs/yarl/issues/891>`__)


Packaging updates and notes for downstreams
-------------------------------------------

- Integrated Cython 3 to enable building *yarl* under Python 3.12 -- by `@mjpieters <https://github.com/sponsors/mjpieters>`__. (`#829 <https://github.com/aio-libs/yarl/issues/829>`__, `#881 <https://github.com/aio-libs/yarl/issues/881>`__)
- Declared modern ``setuptools.build_meta`` as the `PEP 517 <https://peps.python.org/pep-517>`__ build
  backend in ``pyproject.toml`` explicitly -- by `@webknjaz <https://github.com/sponsors/webknjaz>`__. (`#886 <https://github.com/aio-libs/yarl/issues/886>`__)
- Converted most of the packaging setup into a declarative ``setup.cfg``
  config -- by `@webknjaz <https://github.com/sponsors/webknjaz>`__. (`#890 <https://github.com/aio-libs/yarl/issues/890>`__)
- The packaging is replaced from an old-fashioned ``setup.py`` to an
  in-tree `PEP 517 <https://peps.python.org/pep-517>`__ build backend -- by `@webknjaz <https://github.com/sponsors/webknjaz>`__.

  Whenever the end-users or downstream packagers need to build ``yarl`` from
  source (a Git checkout or an sdist), they may pass a ``config_settings``
  flag ``--pure-python``. If this flag is not set, a C-extension will be built
  and included into the distribution.

  Here is how this can be done with ``pip``:

  .. code-block:: console

      $ python -m pip install . --config-settings=--pure-python=false

  This will also work with ``-e | --editable``.

  The same can be achieved via ``pypa/build``:

  .. code-block:: console

      $ python -m build --config-setting=--pure-python=false

  Adding ``-w | --wheel`` can force ``pypa/build`` produce a wheel from source
  directly, as opposed to building an ``sdist`` and then building from it. (`#893 <https://github.com/aio-libs/yarl/issues/893>`__)

  .. attention::

     v1.9.3 was the only version using the ``--pure-python`` setting name.
     Later versions dropped the ``--`` prefix, making it just ``pure-python``.

- Declared Python 3.12 supported officially in the distribution package metadata
  -- by `@edgarrmondragon <https://github.com/sponsors/edgarrmondragon>`__. (`#942 <https://github.com/aio-libs/yarl/issues/942>`__)


Contributor-facing changes
--------------------------

- A regression test for no-host URLs was added per `#821 <https://github.com/aio-libs/yarl/issues/821>`__
  and ``3986`` -- by `@kenballus <https://github.com/sponsors/kenballus>`__. (`#821 <https://github.com/aio-libs/yarl/issues/821>`__, `#822 <https://github.com/aio-libs/yarl/issues/822>`__)
- Started testing *yarl* against Python 3.12 in CI -- by `@mjpieters <https://github.com/sponsors/mjpieters>`__. (`#881 <https://github.com/aio-libs/yarl/issues/881>`__)
- All Python 3.12 jobs are now marked as required to pass in CI
  -- by `@edgarrmondragon <https://github.com/sponsors/edgarrmondragon>`__. (`#942 <https://github.com/aio-libs/yarl/issues/942>`__)
- MyST is now integrated in Sphinx -- by `@webknjaz <https://github.com/sponsors/webknjaz>`__.

  This allows the contributors to author new documents in Markdown
  when they have difficulties with going straight RST. (`#953 <https://github.com/aio-libs/yarl/issues/953>`__)
