 Features
 --------
 
-- Include the package name in a freeze warning if the package is not installed. (`#5943 <https://github.com/pypa/pip/issues/5943>`_)
+- Implement PEP 517 (allow projects to specify a build backend via pyproject.toml). (`#5743 <https://github.com/pypa/pip/issues/5743>`_)
 - Implement manylinux2010 platform tag support.  manylinux2010 is the successor
   to manylinux1.  It allows carefully compiled binary wheels to be installed
   on compatible Linux platforms. (`#5008 <https://github.com/pypa/pip/issues/5008>`_)
-- Editable, non-VCS installs now freeze as editable. (`#5031 <https://github.com/pypa/pip/issues/5031>`_)
-- Include license text of vendored 3rd party libraries. (`#5213 <https://github.com/pypa/pip/issues/5213>`_)
-- Make ``PIP_NO_CACHE_DIR`` disable the cache also for truthy values like
-  ``"true"``, ``"yes"``, ``"1"``, etc. (`#5735 <https://github.com/pypa/pip/issues/5735>`_)
-- Implement PEP 517 (allow projects to specify a build backend via pyproject.toml). (`#5743 <https://github.com/pypa/pip/issues/5743>`_)
+- Improve build isolation: handle ``.pth`` files, so namespace packages are correctly supported under Python 3.2 and earlier. (`#5656 <https://github.com/pypa/pip/issues/5656>`_)
+- Include the package name in a freeze warning if the package is not installed. (`#5943 <https://github.com/pypa/pip/issues/5943>`_)
