Changelog:
=========
Features
-------
Print the exception via rich.traceback, when running with --debug. (#10791)
Bug Fixes
---------
Only calculate topological installation order, for packages that are going to
be installed/upgraded.
This fixes an AssertionError that occured when determining installation order,
for a very specific combination of upgrading-already-installed-package + change
of dependencies + fetching some packages from a package index. This combination
was especially common in Read the Docs' builds. (#10851)
Use html.parser by default, instead of falling back to html5lib when
--use-deprecated=html5lib is not passed. (#10869)
Improved Documentation
----------------------
Clarify that using per-requirement overrides disables the usage of wheels. (#9674)
