2.77.1

This release fixes a very old bug where the Pex PEX (or any other PEX created with
--no-strip-pex-env) would, in fact, strip PEX_PYTHON and PEX_PYTHON_PATH.

• Fix PEX_PYTHON{,_PATH} stripping on Pex re-exec. (#3061)

2.77.0

This release has no fixes or new features per-se, but just changes the set of distributions that
Pex releases to PyPI. Previously Pex released an sdist and a universal (py2.py3-none-any) .whl.
Pex now releases two wheels in addition to the sdist. The py3.py312-none-any.whl targets
Python>=3.12 and has un-needed vendored libraries elided making it both a smaller .whl and less
prone to false-positive security scan issues since unused vendored code is now omitted. The other
wheel carries the same contents as prior and supports creating PEXes for Python 2.7 and
Python>=3.5,<3.12.

• Split Pex .whl into two .whls. (#3057)

2.76.0

This release adds support for --no-scie-pex-entrypoint-env-passthrough to trigger direct execution
of --venv PEX scie script entrypoints. This performance optimization mirrors the existing default
--no-scie-busybox-pex-entrypoint-env-passthrough for busybox scies, but must be selected by
passing --no-scie-pex-entrypoint-env-passthrough explicitly. In addition, the VIRTUAL_ENV env
var is now guaranteed to be set for all --venv PEX scies.

• Add scie support for direct exec of venv scripts. (#3053)
