Changelog for python3-pyproject-hooks: 1.2.0 -> 1.3.0
Source: docs/changelog.rst

v1.3
----

- Python 3.8 or above is now required (:pr:`214`).
- UserWarnings from the backend are now captured and re-emitted in the frontend
  process as a new category ``BuildBackendWarning``, so that frontends can
  control how they are shown to users (:pr:`213`).
- Show the traceback from the backend on a ``BackendUnavailable`` error (:pr:`219`).
- Fix the return type annotation for ``prepare_metadata_for_build_wheel``
  (:pr:`209`).
- Fix removing the internal ``_in_process`` directory from ``sys.path`` where
  the install location includes a symlink (:pr:`230`).
- Use ``os.path.commonpath`` instead of the deprecated ``commonprefix`` to
  validate the location of in-tree backends.
- Fix in-tree backends in locations containing the path separator character -
  ``:`` on Posix platforms, ``;`` on Windows (:pr:`232`).
- Fix finding distribution metadata with ``importlib.metadata`` in the backend
  when an in-tree backend is used (:pr:`212`).
- ``pyproject_hooks`` can be built from source using flit_core 4.x (:pr:`233`).
- Document that the ``hooks.subprocess_runner`` context manager API is not
  thread-safe (:pr:227`)

  in setuptools compatibility in 1.1 (PR :pr:`199`).
  before imporing the backend (PR :pr:`193`).
- Rely on preferred "files" API on Python 3.9 and later (:issue:`140`).
