A notable example is the Pex PEX when +downloaded from https://github.com/pantsbuild/pex/releases. + +* Fix zipapp layout identification. (#1448) + `PR #1448 <https://github.com/pantsbuild/pex/pull/1448>`_ + +2.1.49 +------ + +This is a hotfix release that fixes the new ``--layout {zipapp,packed}`` +modes for PEX files with no user code & just third party dependencies +when executed against a ``$PEX_ROOT`` where similar PEXes built with the +old ``--not-zip-safe`` option were were run in the past. + +* Avoid re-using old ~/.pex/code/ caches. (#1444) + `PR #1444 <https://github.com/pantsbuild/pex/pull/1444>`_ + +2.1.48 +------ + +This releases introduces the ``--layout`` flag for selecting amongst the +traditional zipapp layout as a single PEX zip file and two new directory +tree based formats that may be useful for more sophisticated deployment +sceanrios. + +The ``--unzip`` / ``PEX_UNZIP`` toggles for PEX runtime execution are +now the default and deprecated as explicit options as a result. You can +still select the venv runtime execution mode via the +``--venv`` / ``PEX_VENV`` toggles though. + +* Remove zipapp execution mode & introduce ``--layout``. (#1438) + `PR #1438 <https://github.com/pantsbuild/pex/pull/1438>`_ + +2.1.47 +------ + +This is a hotfix release that fixes a regression for ``--venv`` mode +PEXes introduced in #1410. These PEXes were not creating new venvs when +the PEX was unconstrained and executed with any other interpreter than +the interpreter the venv was first created with. + +* Fix ``--venv`` mode venv dir hash. (#1428) + `PR #1428 <https://github.com/pantsbuild/pex/pull/1428>`_ + +* Clarify PEX_PYTHON & PEX_PYTHON_PATH interaction. (#1427) + `PR #1427 <https://github.com/pantsbuild/pex/pull/1427>`_ + +2.1.46 +------ + +This release improves PEX file build reproducibility and requirement +parsing of environment markers in Pip's proprietary URL format. + +Also, the `-c` / `--script` / `--console-script` argument now supports +non-Python distribution scripts. + +Finally, new contributor @blag improved the README. + +* Fix Pip proprietary URL env marker handling. (#1417) + `PR #1417 <https://github.com/pantsbuild/pex/pull/1417>`_ + +* Un-reify installed wheel script shebangs. (#1410) + `PR #1410 <https://github.com/pantsbuild/pex/pull/1410>`_ + +* Support deterministic repository extract tool. (#1411) + `PR #1411 <https://github.com/pantsbuild/pex/pull/1411>`_ + +* Improve examples and add example subsection titles (#1409) + `PR #1409 <https://github.com/pantsbuild/pex/pull/1409>`_ + +* support any scripts specified in `setup(scripts=...)` from setup.py. (#1381) + `PR #1381 <https://github.com/pantsbuild/pex/pull/1381>`_ + +2.1.45 +------ + +This is a hotfix release that fixes the ``--bdist-all`` handling in the +``bdist_pex`` distutils command that regressed in 2.1.43 to only create +a bdist for the first discovered entry point. + +* Fix --bdist-all handling multiple console_scripts (#1396) + `PR #1396 <https://github.com/pantsbuild/pex/pull/1396>`_ + +2.1.44 +------ + +This is a hotfix release that fixes env var collisions (introduced in +the Pex 2.1.43 release by +`PR #1367 <https://github.com/pantsbuild/pex/pull/1367>`_) that could +occur when invoking Pex with environment variables like ``PEX_ROOT`` +defined. + +* Fix Pip handling of internal env vars. (#1388) + `PR #1388 <https://github.com/pantsbuild/pex/pull/1388>`_ + +2.1.43 +------ + +* Fix dist-info metadata discovery.

(#1338) + `PR #1338 <https://github.com/pantsbuild/pex/pull/1338>`_ + +* Better isolate Pip. (#1339) + `PR #1339 <https://github.com/pantsbuild/pex/pull/1339>`_ + +2.1.41 +------ + +This release brings a hotfix from @kaos for interpreter identification +on macOS 11. + +* Update interpreter.py (#1332) + `PR #1332 <https://github.com/pantsbuild/pex/pull/1332>`_ + +2.1.40 +------ + +This release brings proper support for pyenv shim interpreter +identification as well as a bug fix for venv mode. + +* Fix Pex venv mode to respect ``--strip-pex-env``. (#1329) + `PR #1329 <https://github.com/pantsbuild/pex/pull/1329>`_ + +* Fix pyenv shim identification. (#1325) + `PR #1325 <https://github.com/pantsbuild/pex/pull/1325>`_ + +2.1.39 +------ + +A hotfix that fixes a bug present since 2.1.25 that results in infinite +recursion in PEX runtime resolves when handling dependency cycles. + +* Guard against cyclic dependency graphs. (#1317) + `PR #1317 <https://github.com/pantsbuild/pex/pull/1317>`_ + +2.1.38 +------ + +A hotfix that finishes work started in 2.1.37 by #1304 to align Pip +based resolve results with ``--pex-repository`` based resolve results +for requirements with '.' in their names as allowed by PEP-503. + +* Fix PEX direct requirements metadata.

(#1301) + `PR #1301 <https://github.com/pantsbuild/pex/pull/1301>`_ + +2.1.36 +------ + +This release brings a fix for building sdists with certain macOS +interpreters when creating a PEX file that would then fail to resolve +on PEX startup. + +* Add support for ``--seed verbose``. (#1299) + `PR #1299 <https://github.com/pantsbuild/pex/pull/1299>`_ + +* Fix bytecode compilation race in PEXBuilder.build. (#1298) + `PR #1298 <https://github.com/pantsbuild/pex/pull/1298>`_ + +* Fix wheel building for certain macOS system interpreters. (#1296) + `PR #1296 <https://github.com/pantsbuild/pex/pull/1296>`_ + +2.1.35 +------ + +This release hardens a few aspects of `--venv` mode PEXes. An infinite +re-exec loop in venv `pex` scripts is fixed and the `activate` family +of scripts in the venv is fixed. + +* Improve resolve error information. (#1287) + `PR #1287 <https://github.com/pantsbuild/pex/pull/1287>`_ + +* Ensure venv pex does not enter a re-exec loop.

(#1227) + `PR #1227 <https://github.com/pantsbuild/pex/pull/1227>`_ + +2.1.29 +------ + +This release fixes bugs in `--unzip` and `--venv` mode PEX file execution and upgrades to the last +release of Pip to support Python 2.7. + +* Fix PyPy3 `--venv` mode. (#1221) + `PR #1221 <https://github.com/pantsbuild/pex/pull/1221>`_ + +* Make `PexInfo.pex_hash` calculation more robust. (#1219) + `PR #1219 <https://github.com/pantsbuild/pex/pull/1219>`_ + +* Upgrade to Pip 20.3.4 patched. (#1205) + `PR #1205 <https://github.com/pantsbuild/pex/pull/1205>`_ + +2.1.28 +------ + +This is another hotfix release to fix incorrect resolve post-processing failing otherwise correct +resolves. + +* Pex resolver fails to evaluate markers when post-processing resolves to identify which dists + satisfy direct requirements. (#1196) + `PR #1196 <https://github.com/pantsbuild/pex/pull/1196>_` + +2.1.27 +------ + +This is another hotfix release to fix a regression in Pex ``--sources-directory`` handling of +relative paths. + +* Support relative paths in `Chroot.symlink`. (#1194) + `PR #1194 <https://github.com/pantsbuild/pex/pull/1194>_` + +2.1.26 +------ + +This is a hotfix release that fixes requirement parsing when there is a local file in the CWD with +the same name as the project name of a remote requirement to be resolved. + +* Requirement parsing handles local non-dist files. (#1190) + `PR #1190 <https://github.com/pantsbuild/pex/pull/1190>`_ + +2.1.25 +------ + +This release brings support for a ``--venv`` execution mode to complement ``--unzip`` and standard +unadorned PEX zip file execution modes. The ``--venv`` execution mode will first install the PEX +file into a virtual environment under ``${PEX_ROOT}/venvs`` and then re-execute itself from there. +This mode of execution allows you to ship your PEXed application as a single zipfile that +automatically installs itself in a venv and runs from there to eliminate all PEX startup overhead +on subsequent runs and work like a "normal" application. + +There is also support for a new resolution mode when building PEX files that allows you to use the +results of a previous resolve by specifying it as a ``-pex-repository`` to resolve from. If you have +many applications sharing a requirements.txt / constraints.txt, this can drastically speed up +resolves. + +* Improve PEX repository error for local projects. (#1184) + `PR #1184 <https://github.com/pantsbuild/pex/pull/1184>`_ + +* Use symlinks to add dists in the Pex CLI. (#1185) + `PR #1185 <https://github.com/pantsbuild/pex/pull/1185>`_ + +* Suppress ``pip debug`` warning. (#1183) + `PR #1183 <https://github.com/pantsbuild/pex/pull/1183>`_ + +* Support resolving from a PEX file repository. (#1182) + `PR #1182 <https://github.com/pantsbuild/pex/pull/1182>`_ + +* PEXEnvironment for a DistributionTarget. (#1178) + `PR #1178 <https://github.com/pantsbuild/pex/pull/1178>`_ + +* Fix plumbing of 2020-resolver to Pip. (#1180) + `PR #1180 <https://github.com/pantsbuild/pex/pull/1180>`_ + +* Platform can report supported_tags. (#1177) + `PR #1177 <https://github.com/pantsbuild/pex/pull/1177>`_ + +* Record original requirements in PEX-INFO. (#1171) + `PR #1171 <https://github.com/pantsbuild/pex/pull/1171>`_ + +* Tighten requirements parsing.

(#1168) + `PR #1168 <https://github.com/pantsbuild/pex/pull/1168>`_ + +* Type SpawnedJob. (#1167) + `PR #1167 <https://github.com/pantsbuild/pex/pull/1167>`_ + +* Refresh and type OrderedSet. (#1166) + `PR #1166 <https://github.com/pantsbuild/pex/pull/1166>`_ + +* PEXEnvironment recursive runtime resolve. (#1165) + `PR #1165 <https://github.com/pantsbuild/pex/pull/1165>`_ + +* Add support for -r / --constraints URL to the CLI. (#1163) + `PR #1163 <https://github.com/pantsbuild/pex/pull/1163>`_ + +* Surface Pip dependency conflict information. (#1162) + `Issue #9420 <https://github.com/pypa/pip/issues/9420>`_ + `PR #1162 <https://github.com/pantsbuild/pex/pull/1162>`_ + +* Add support for parsing extras and specifiers. (#1161) + `PR #1161 <https://github.com/pantsbuild/pex/pull/1161>`_ + +* Support project_name_and_version metadata. (#1160) + `PR #1160 <https://github.com/pantsbuild/pex/pull/1160>`_ + +* docs: fix simple typo, orignal -> original (#1156) + `PR #1156 <https://github.com/pantsbuild/pex/pull/1156>`_ + +* Support a --venv mode similar to --unzip mode. (#1153) + `PR #1153 <https://github.com/pantsbuild/pex/pull/1153>`_ + +* Remove redundant dep edge label info. (#1152) + `PR #1152 <https://github.com/pantsbuild/pex/pull/1152>`_ + +* Remove our reliance on packaging's LegacyVersion.

(#1148) + `PR #1148 <https://github.com/pantsbuild/pex/pull/1148>`_ + +2.1.24 +------ + +This release upgrades Pip to 20.3.3 + a patch to fix Pex resolves using +the ``pip-legacy-resolver`` and ``--constraints``. The Pex package is +also fixed to install for Python 3.9.1+. + +* Upgrade to a patched Pip 20.3.3. (#1143) + `Issue #9283 <https://github.com/pypa/pip/issues/9283>`_ + `PR #1143 <https://github.com/pantsbuild/pex/pull/1143>`_ + +* Fix python requirement to include full 3.9 series. (#1142) + `PR #1142 <https://github.com/pantsbuild/pex/pull/1142>`_ + +2.1.23 +------ + +This release upgrades Pex to the latest Pip which includes support for +the new 2020-resolver (see: +https://pip.pypa.io/en/stable/user_guide/#resolver-changes-2020) as well +as support for macOS BigSur. Although this release defaults to the +legacy resolver behavior, the next release will deprecate the legacy +resolver and support for the legacy resolver will later be removed to +allow continuing Pip upgrades going forward. To switch to the new +resolver, use: `--resolver-version pip-2020-resolver`. + +* Upgrade Pex to Pip 20.3.1. (#1133) + `PR #1133 <https://github.com/pantsbuild/pex/pull/1133>`_ + +2.1.22 +------ + +This release fixes a deadlock that could be experienced when building +PEX files in highly concurrent environments in addition to fixing +`pex --help-variables` output. + +A new suite of PEX tools is now available in Pex itself and any PEXes +built with the new `--include-tools` option. Use +`PEX_TOOLS=1 pex --help` to find out more about the available tools and +their usage. + +Finally, the long deprecated exposure of the Pex APIs through `_pex` has +been removed. To use the Pex APIs you must include pex as a dependency +in your PEX file. + +* Add a dependency graph tool. (#1132) + `PR #1132 <https://github.com/pantsbuild/pex/pull/1132>`_ + +* Add a venv tool.

(#1072) + `PR #1072 <https://github.com/pantsbuild/pex/pull/1072>`_ + +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.

(#1014) + `PR #1014 <https://github.com/pantsbuild/pex/pull/1014>`_ + +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) + `PR #1008 <https://github.com/pantsbuild/pex/pull/1008>`_ + +* Autoformat with Black. (#1006) + `PR #1006 <https://github.com/pantsbuild/pex/pull/1006>`_ + +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) + `PR #1000 <https://github.com/pantsbuild/pex/pull/1000>`_ + +* Improve --platform help.

(#976) + `PR #976 <https://github.com/pantsbuild/pex/pull/976>`_ + +2.1.10 +------ + +This release focuses on the resolver API and resolution performance. Pex 2 resolving using Pip is +now at least at performance parity with Pex 1 in all studied cases and most often is 5% to 10% +faster. + +As part of the resolution performance work, Pip networking configuration is now exposed via Pex CLI +options and the ``NetworkConfiguration`` API type / new ``resolver.resolve`` API parameter. + +With network configuration now wired up, the ``PEX_HTTP_RETRIES`` and ``PEX_HTTP_TIMEOUT`` env var +support in Pex 1 that was never wired into Pex 2 is now dropped in favor of passing ``--retries`` +and ``--timeout`` via the CLI (See: `Issue #94 <https://github.com/pantsbuild/pex/issues/94>`_) + +* Expose Pip network configuration. (#974) + `PR #974 <https://github.com/pantsbuild/pex/pull/974>`_ + +* Restore handling for bad wheel filenames to ``.can_add()`` (#973) + `PR #973 <https://github.com/pantsbuild/pex/pull/973>`_ + +* Fix wheel filename parsing in PEXEnvironment.can_add (#965) + `PR #965 <https://github.com/pantsbuild/pex/pull/965>`_ + +* Split Pex resolve API.

(#954) + `PR #954 <https://github.com/pantsbuild/pex/pull/954>`_ + +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) + `PR #948 <https://github.com/pantsbuild/pex/pull/948>`_ + + +2.1.8 +----- + +This release brings enhanced performance when using the Pex CLI or API to resolve requirements and +improved performance for many PEXed applications when specifying the `--unzip` option. PEXes built +with `--unzip` will first unzip themselves into the Pex cache if not unzipped there already and +then re-execute themselves from there. This can improve startup latency. Pex itself now uses this +mode in our [PEX release](https://github.com/pantsbuild/pex/releases/download/v2.1.8/pex). + +* Better support unzip mode PEXes. (#941) + `PR #941 <https://github.com/pantsbuild/pex/pull/941>`_ + +* Support an unzip toggle for PEXes. (#939) + `PR #939 <https://github.com/pantsbuild/pex/pull/939>`_ + +* Ensure the interpreter path is a file (#938) + `PR #938 <https://github.com/pantsbuild/pex/pull/938>`_ + +* Cache pip.pex. (#937) + `PR #937 <https://github.com/pantsbuild/pex/pull/937>`_ + +2.1.7 +----- + +This release brings more robust control of the Pex cache (PEX_ROOT). + +The `--cache-dir` setting is deprecated in favor of build time control of the cache location with +`--pex-root` and new support for control of the cache's runtime location with `--runtime-pex-root` +is added. As in the past, the `PEX_ROOT` environment variable can still be used to control the +cache's runtime location. + +Unlike in the past, the [Pex PEX](https://github.com/pantsbuild/pex/releases/download/v2.1.7/pex) +we release can now also be controlled via the `PEX_ROOT` environment variable. Consult the CLI help +for `--no-strip-pex-env` to find out more. + +* Sanitize PEX_ROOT handling.

In addition, performance of the pex 2.x +resolver is brought in line with the 1.x resolver in all cases and improved in +most cases. + +* Unify PEX buildtime and runtime wheel caches. #821 + `PR #821 <https://github.com/pantsbuild/pex/pull/821>`_ + +* Parallelize resolve.

This +fixes a large number of compatibility and correctness bugs as well as gaining +feature support from pip including handling manylinux2010 and manylinux2014 as +well as VCS requirements and support for PEP-517 & PEP-518 builds. + +API changes to be wary of: + +* The egg distribution format is no longer supported. +* The deprecated ``--interpreter-cache-dir`` CLI option was removed. +* The ``--cache-ttl`` CLI option and ``cache_ttl`` resolver API argument were + removed. +* The resolver API replaced ``fetchers`` with a list of ``indexes`` and a list + of ``find_links`` repos. +* The resolver API removed (http) ``context`` which is now automatically + handled. +* The resolver API removed ``precedence`` which is now pip default precedence: + wheels when available and not ruled out via the ``--no-wheel`` CLI option or + ``use_wheel=False`` API argument. +* The ``--platform`` CLI option and ``platform`` resolver API argument now must + be full platform strings that include platform, implementation, version and + abi; e.g.: ``--platform=macosx-10.13-x86_64-cp-36-m``. +* The ``--manylinux`` CLI option and ``use_manylinux`` resolver API argument + were removed. Instead, to resolve manylinux wheels for a foreign platform, + specify the manylinux platform to target with an explicit ``--platform`` CLI + flag or ``platform`` resolver API argument; e.g.: + ``--platform=manylinux2010-x86_64-cp-36-m``. + +In addition, Pex 2.0.0 now builds reproduceable pexes by default; ie: + +* Python modules embedded in the pex are not pre-compiled (pass --compile if + you want this). +* The timestamps for Pex file zip entries default to midnight on + January 1, 1980 (pass --use-system-time to change this). + +This finishes off the effort tracked by +`Issue #716 <https://github.com/pantsbuild/pex/pull/718>`_ + +Changes in this release: + +* Pex defaults to reproduceable builds.

Any backwards incompatible changes to the PEX +environment variable semantics will also result in a major version change. The pex *API* adheres +to semver insofar as backwards incompatible API changes will invoke minor version changes. + +For users of the PEX API, it is recommended to add minor version ranges, e.g. ``pex>=1.0,<1.1``. +For users of the PEX CLI, major version ranges such as ``pex>=1,<2`` should be sufficient. + +* BREAKING CHANGE: Removes the ``-s`` option in favor of specifying directories directly as + arguments to the pex command line. + +* BREAKING CHANGE: ``pex -r`` now takes requirements.txt filenames and *not* requirement + specs. Requirement specs are now passed as arguments to the pex tool. Use ``--`` to escape + command line arguments passed to interpreters spawned by pex. Implements + `#5 <https://github.com/pantsbuild/pex/issues/5>`_. + +* Adds a number of flag aliases to be more compatible with pip command lines: ``--no-index``, + ``-f``, ``--find-links``, ``--index-url``, ``--no-use-wheel``. Removes ``-p`` in favor of + ``-o`` exclusively. + +* Adds ``--python-shebang`` option to the pex tool in order to set the ``#!`` shebang to an exact + path. `#53 <https://github.com/pantsbuild/pex/issues/53>`_. + +* Adds support for ``PEX_PYTHON`` environment variable which will cause the pex file to reinvoke + itself using the interpreter specified, e.g. ``PEX_PYTHON=python3.4`` or + ``PEX_PYTHON=/exact/path/to/interpreter``. `#27 <https://github.com/pantsbuild/pex/issues/27>`_. + +* Adds support for ``PEX_PATH`` environment variable which allows merging of PEX environments at + runtime. This can be used to inject plugins or entry_points or modules from one PEX into + another without explicitly building them together. `#30 <https://github.com/pantsbuild/pex/issues/30>`_. + +* Consolidates documentation of ``PEX_`` environment variables and adds the ``--help-variables`` option + to the pex client. Partially addresses `#13 <https://github.com/pantsbuild/pex/issues/13>`_. + +* Adds helper method to dump a package subdirectory onto disk from within a zipped PEX file. This + can be useful for applications that know they're running within a PEX and would prefer some + static assets dumped to disk instead of running as an unzipped PEX file. + `#12 <https://github.com/pantsbuild/pex/pull/12>`_. + +* Now supports extras for static URLs and installable directories. + `#65 <https://github.com/pantsbuild/pex/issues/65>`_. + +* Adds ``-m`` and ``--entry-point`` alias to the existing ``-e`` option for entry points in + the pex tool to evoke the similarity to ``python -m``. + +* Adds console script support via ``-c/--script/--console-script`` and ``PEX_SCRIPT``. This allows + you to reference the named entry point instead of the exact ``module:name`` pair. Also supports + scripts defined in the ``scripts`` section of setup.py. + `#59 <https://github.com/pantsbuild/pex/issues/59>`_. + +* Adds more debugging information when encountering unresolvable requirements. + `#79 <https://github.com/pantsbuild/pex/issues/79>`_. + +* Bug fix: ``PEX_COVERAGE`` and ``PEX_PROFILE`` did not function correctly when SystemExit was raised. + Fixes `#81 <https://github.com/pantsbuild/pex/issues/81>`_. + +* Bug fix: Fixes caching in the PEX tool since we don't cache the source distributions of installable + directories. `#24 <https://github.com/pantsbuild/pex/issues/24>`_. + +0.9.0 +----- + +This is the last release before the 1.0.0 development branch is started. + +* Change the setuptools range to >=2.2,<16 by handling EntryPoint changes as well as + being flexible on whether ``pkg_resources`` is a package or a module. Fixes + `#55 <https://github.com/pantsbuild/pex/issues/55>`_ and + `#34 <https://github.com/pantsbuild/pex/issues/34>`_. + +* Adds option groups to the pex tool to make the help output slightly more readable. + +* Bug fix: Make ``pip install pex`` work better by removing ``extras_requires`` on the + ``console_script`` entry point. Fixes `#48 <https://github.com/pantsbuild/pex/issues/48>`_ + +* New feature: Adds an interpreter cache to the ``pex`` tool.
