2.1.20

This release improves interpreter discovery to prefer more recent patch versions, e.g. preferring
Python 3.6.10 over 3.6.8.

We recently regained access to the docsite, and https://pex.readthedocs.io/en/latest/ is now
up-to-date.

• Prefer more recent patch versions in interpreter discovery. (#1088)

• Fix --pex-python when it's the same as the current interpreter. (#1087)

• Fix dir_hash vs. bytecode compilation races. (#1080)

• Fix readthedocs doc generation. (#1081)

pex 2.1.19

2.1.19

This release adds the --python-path option, which allows controlling the
interpreter search paths when building a PEX.

The release also removes --use-first-matching-interpreter, which was a misfeature. If you want to use
fewer interpreters when building a PEX, use more precise values for --interpreter-constraint and/or
--python-path, or use --python or --platform.

• Add --python-path to change interpreter search paths when building a PEX. (#1077)
• Remove --use-first-matching-interpreter misfeature. (#1076)
• Encapsulate --inherit-path handling. (#1072)

pex 2.1.18

2.1.18

This release brings official support for Python 3.9 and adds a new --tmpdir option to explicitly
control the TMPDIR used by Pex and its subprocesses. The latter is useful when building PEXes in
space-constrained environments in the face of large distributions.

The release also fixes --cert and --client-cert so that they work with PEP-518 builds in
addition to fixing bytecode compilation races in highly parallel environments.

• Add a --tmpdir option to the Pex CLI. (#1068)
• Honor sys.executable unless macOS Framework. (#1065)
• Add Python 3.9 support. (#1064)
• Fix handling of --cert and --client-cert. (#1063)
• Add atomic_directory exclusive mode. (#1062)
• Fix --cert for PEP-518 builds. (#1060)

pex 2.1.17

---

2.1.17

This release fixes a bug in --resolve-local-platforms handling that made it unusable in 2.1.16
(#1043) as well as fixing a long standing file handle leak (#1050) and a bug when running under
macOS framework builds of Python (#1009).

• Fix --unzip performance regression. (#1056)
• Fix resource leak in Pex self-isolation. (#1052)
• Fix use of iter_compatible_interpreters. (#1048)
• Do not rely on sys.executable being accurate. (#1049)
• slightly demystify the relationship between platforms and interpreters in the library API and CLI (#1047)
• Path filter for PythonInterpreter.iter_candidates. (#1046)
• Add type hints to util.py and tracer.py (#1044)
• Add type hints to variables.py and platforms.py (#1042)
• Add type hints to the remaining tests (#1040)
• Add type hints to most tests (#1036)
• Use MyPy via type comments (#1032)

pex 2.1.16

2.1.16

This release fixes a bug in sys.path scrubbing / hermeticity (#1025) and a bug in the -D / --sources-directory and -R / --resources-directory options whereby PEP-420 implicit (namespace) packages were not respected (#1021).

• Improve UnsatisfiableInterpreterConstraintsError. (#1028)
• Scrub direct sys.path manipulations by .pth files. (#1026)
• PEX zips now contain directory entries. (#1022)
• Fix UnsatisfiableInterpreterConstraintsError. (#1024)

pex 2.1.15

---

2.1.15

A patch release to fix an issue with the --use-first-matching-interpreter flag.

• Fix --use-first-matching-interpreter at runtime. (#1014)

pex 2.1.14

---

2.1.14

This release adds the --use-first-matching-interpreter flag, which
can speed up performance when building a Pex at the expense of being
compatible with fewer interpreters at runtime.

• Add --use-first-matching-interpreter. (#1008)
• Autoformat with Black. (#1006)

pex 2.1.13

---

2.1.13

The focus of this release is better support of the --platform CLI
arg. Platforms are now better documented and can optionally be resolved
to local interpreters when possible via --resolve-local-platforms to
better support creation of multiplatform PEXes.

• Add support for resolving --platform locally. (#1000)
• Improve --platform help. (#1002)
• Improve and fix --platform help. (#1001)
• Ensure pip download dir is uncontended. (#998)

pex 2.1.12

---

2.1.12

A patch release to deploy the PEX_EXTRA_SYS_PATH feature.

• A PEX_EXTRA_SYS_PATH runtime variable. (#989)
• Fix typos (#986)
• Update link to avoid a redirect (#982)

pex 2.1.11

---

2.1.11

A patch release to fix a symlink issue in remote execution environments.

• use relative paths within wheel cache (#979)
• Fix Tox not finding Python 3.8 on OSX. (#976)
