New resolver: Correctly exclude an already installed package if its version is
known to be incompatible to stop the dependency resolution process with a clear
error message. ([#9841](https://github.com/pypa/pip/issues/9841) <https://github.com/pypa/pip/issues/9841>_)
Allow ZIP to archive files with timestamps earlier than 1980. ([#9910](https://github.com/pypa/pip/issues/9910) <https://github.com/pypa/pip/issues/9910>_)
Emit clearer error message when a project root does not contain either
pyproject.toml, setup.py or setup.cfg. ([#9944](https://github.com/pypa/pip/issues/9944) <https://github.com/pypa/pip/issues/9944>_)
Fix detection of existing standalone pip instance for PEP 517 builds. ([#9953](https://github.com/pypa/pip/issues/9953) <https://github.com/pypa/pip/issues/9953>_)
21.1.1 (2021-04-30)
Deprecations and Removals
Temporarily set the new "Value for ... does not match" location warnings level
to DEBUG, to hide them from casual users. This prepares pip 21.1 for CPython
inclusion, while pip maintainers digest the first intake of location mismatch
issues for the distutils-sysconfig transition. ([#9912](https://github.com/pypa/pip/issues/9912) <https://github.com/pypa/pip/issues/9912>_)
Bug Fixes
This change fixes a bug on Python `_)
Fix compatibility between distutils and sysconfig when the project name is unknown outside of a virtual environment. ([#9838](https://github.com/pypa/pip/issues/9838) <https://github.com/pypa/pip/issues/9838>_)
Fix Python 3.6 compatibility when a PEP 517 build requirement itself needs to be
built in an isolated environment. ([#9878](https://github.com/pypa/pip/issues/9878) <https://github.com/pypa/pip/issues/9878>_)
21.1 (2021-04-24)
Process
Start installation scheme migration from distutils to sysconfig. A
warning is implemented to detect differences between the two implementations to
encourage user reports, so we can avoid breakages before they happen.
Features
Add the ability for the new resolver to process URL constraints. ([#8253](https://github.com/pypa/pip/issues/8253) <https://github.com/pypa/pip/issues/8253>_)
Add a feature --use-feature=in-tree-build to build local projects in-place
