2.1.9
This release introduces the ability to copy requirements from an existing PEX into a new one.
This can greatly speed up repeatedly creating a PEX when no requirements have changed.
A build tool (such as Pants) can create a "requirements PEX" that contains just a static
set of requirements, and build a final PEX on top of that, without having to re-run pip
to resolve requirements.
- Support for copying requirements from an existing pex. (#948)
