========== 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)

Bugfixes

---

• Ensure the uv installer uses the current version of Python, avoiding an issue if UV_PYTHON is set, for example. (:issue:977)
• Fix _has_valid_outer_pip returning True when pip is missing, causing build to try using a non-existent pip instead of falling back to virtualenv. (:issue:1003)
