• #1083: Also use makedirs compatibility throughout setuptools.

• #1042: Fix import in py27compat module that still referenced six directly, rather than through the externs module (vendored packages hook).

• #1015: Fix test failures on Python 3.7.

• #1024: Add workaround for Jython #2581 in monkey module.

• #992: Revert change introduced in v34.4.1, now considered invalid.

• #1016: Revert change introduced in v35.0.0 per #1014, referencing #436. The approach had unintended consequences, causing sdist installs to be missing files.

• #436: In egg_info.manifest_maker, no longer read the file list from the manifest file, and instead re-build it on each build. In this way, files removed from the specification will not linger in the manifest. As a result, any files manually added to the manifest will be removed on subsequent egg_info invocations. No projects should be manually adding files to the manifest and should instead use MANIFEST.in or SCM file finders to force inclusion of files in the manifest.

• #1008: In MSVC support, fix "vcruntime140.dll" returned path with Visual Studio 2017.

• #995: In MSVC support, add support for "Microsoft Visual Studio 2017" and "Microsoft Visual Studio Build Tools 2017".

• #999 via #1007: Extend support for declarative package config in a setup.cfg file to include the options python_requires and py_modules.

• #967 (and #997): Explicitly import submodules of packaging to account for environments where the imports of those submodules is not implied by other behavior.

• #993: Fix documentation upload by correcting rendering of content-type in _build_multipart on Python 3.

• #988: Trap os.unlink same as os.remove in auto_chmod error handler.

• #930: build_info now accepts two new parameters to optimize and customize the building of C libraries.
