2.20.1

This release fixes Pex --interpreter-constraint handling such that
any supplied interpreter constraints which are in principle
unsatisfiable either raise an error or else cause a warning to be issued
when other viable interpreter constraints have also been specified. For
example, --interpreter-constraint ==3.11.*,==3.12.* now errors and
--interpreter-constraint '>=3.8,<3.8' --interpreter-constraint ==3.9.*
now warns, culling >3.8,<3.8 and continuing using only ==3.9.*.

• Pre-emptively cull unsatisfiable interpreter constraints. (#2542)
