* Actually use system trust stores when the truststore feature
is enabled.
* Report informative messages about invalid requirements.
* Eagerly import the self version check logic to avoid crashes
while upgrading or downgrading pip at the same time.
* Accommodate for mismatches between different sources of truth
for extra names, for packages generated by setuptools.
* Accommodate for development versions of CPython ending in +
in the version string.
* requests provides optional character detection support on
some APIs when processing ambiguous bytes. This isn't
relevant for pip to function and we're able to remove it due
to recent upstream changes.
* Drop support for EOL Python 3.7.
* Remove support for legacy versions and dependency specifiers.
* Packages with non standard-compliant versions or dependency
specifiers are now ignored by the resolver. Already installed
packages with non standard-compliant versions or dependency
specifiers must be uninstalled before upgrading them.
* Improve performance of resolution of large dependency trees,
with more caching.
* Further improve resolution performance of large dependency
trees, by caching hash calculations.
* Reduce startup time of commands (e.g. show, freeze) that do
not access the network by 15-30%.
* Reword and improve presentation of uninstallation errors.
* Add a 'raw' progress_bar type for simple and parsable
download progress reports
* pip list no longer performs the pip version check unless
