  PRs and issues: #2318

  PRs and issues: #2387

• A handful of f-string conversions in piptools.utils and the CLI entry points in piptools.scripts.compile and piptools.scripts.sync carried a stray space before !s (e.g. f"...{value !s}..."). PEP 498 forbids the whitespace before the conversion flag and tooling differs on whether the form parses; the literals are now in canonical {value!s} shape -- by @gaborbernat.

  PRs and issues: #2388

• A session-scoped autouse fixture in tests/conftest.py now drops every PIP_* environment variable before any other fixture runs, so the test suite no longer flakes on contributor machines whose shell exports PIP_INDEX_URL, PIP_FIND_LINKS, PIP_TRUSTED_HOST, and the rest of the family for a corporate mirror. Tests that need a specific variable keep their function-scoped pytest:pytest.MonkeyPatch.setenv and supersede the session-level deletion -- by @gaborbernat.

  PRs and issues: #2390

• The Sphinx configuration now resolves cross-references for packaging, pip, click, build, and importlib_metadata via intersphinx, and the deprecated sphinx.util.console.bold helper is replaced with a plain logger.info call (the colour markup never rendered in CI logs anyway).

  PRs and issues: #2391

  PRs and issues: #2150

• Fixed a bug in which pip-compile lost any index URL options when
  looking up hashes -- by @sirosen.

  This caused errors when a package was only available from an extra
  index, and caused pip-compile to incorrectly drop index URL options
  from output, even when they were present in the input requirements.

  PRs and issues: #2220, #2294, #2305
