********************

==========
 Features
==========

- Add ``kind`` parameter to log messages to separate semantic and representation - by :user:`abitrolly` (:issue:`973`)

==========
 Bugfixes
==========

- Strip ``PYTHONPATH`` from the environment during isolated builds to prevent host packages from leaking into the build -
  by :user:`gaborbernat` (:issue:`405`)
- Pass ``--no-input`` to pip to prevent hidden credential prompts that cause hangs, and automatically set
  ``PIP_KEYRING_PROVIDER=subprocess`` (or ``UV_KEYRING_PROVIDER=subprocess`` for the uv installer) when the ``keyring``
  CLI is on ``PATH`` -- by :user:`gaborbernat` (:issue:`409`)
- ``check_dependency`` now reports URL requirements as unmet instead of silently accepting them when a package with the
  same name is installed - by :user:`gaborbernat` (:issue:`860`)
- Fix misleading missing dependency error display where transitive dependency chains showed the top-level package on a
  separate line, making it appear as if the top-level package itself was missing - by :user:`gaborbernat` (:issue:`875`)
- Fix towncrier template to generate changelog categories in definition order - by :user:`gaborbernat` (:issue:`1007`)
- Resolve thread-safety races in the build API - by :user:`gaborbernat` (:issue:`1015`)
- Validate ``backend-path`` entries exist on disk with a clear error - by :user:`gaborbernat` (:issue:`1016`)
