- Update to 19.0.2 (2019-02-09):
+ Bug Fixes
* Fix a crash where PEP 517-based builds using --no-cache-dir
would fail in some circumstances with an AssertionError due
to not finalizing a build directory internally. (#6197)
* Provide a better error message if attempting an editable
install of a directory with a pyproject.toml but no setup.py.
(#6170)
* The implicit default backend used for projects that provide a
pyproject.toml file without explicitly specifying build-
backend now behaves more like direct execution of setup.py,
and hence should restore compatibility with projects that
were unable to be installed with pip 19.0. This raised the
minimum required version of setuptools for such builds to
40.8.0. (#6163)
* Allow RECORD lines with more than three elements, and display
a warning. (#6165)
* AdjacentTempDirectory fails on unwritable directory instead
of locking up the uninstall command. (#6169)
* Make failed uninstalls roll back more reliably and better at
avoiding naming conflicts. (#6194)
* Ensure the correct wheel file is copied when building PEP 517
distribution is built. (#6196)
* The Python 2 end of life warning now only shows on CPython,
which is the implementation that has announced end of life
plans. (#6207)
+ Improved Documentation
* Re-write README and documentation index (#5815)
