2018.6.25 (2018-06-25)

Features & Improvements

• Pipenv-created virtualenvs will now be associated with a .project folder (features can be implemented on top of this later or users may choose to use pipenv-pipes to take full advantage of this.) #1861
• Virtualenv names will now appear in prompts for most Windows users. #2167
• Added support for cmder shell paths with spaces. #2168
• Added nested JSON output to the pipenv graph command. #2199
• Dropped vendored pip 9 and vendored, patched, and migrated to pip 10. Updated patched piptools version. #2255
• PyPI mirror URLs can now be set to override instances of PyPI urls by passing the --pypi-mirror argument from the command line or setting the PIPENV_PYPI_MIRROR environment variable. #2281
• Virtualenv activation lines will now avoid being written to some shell history files. #2287
• Pipenv will now only search for requirements.txt files when creating new projects, and during that time only if the user doesn't specify packages to pass in. #2309
• Added support for mounted drives via UNC paths. #2331
• Added support for Windows Subsystem for Linux bash shell detection. #2363
• Pipenv will now generate hashes much more quickly by resolving them in a single pass during locking. #2384
• pipenv run will now avoid spawning additional COMSPEC instances to run commands in when possible. #2385
• Massive internal improvements to requirements parsing codebase, resolver, and error messaging. #2388
• pipenv check now may take multiple of the additional argument --ignore which takes a parameter cve_id for the purpose of ignoring specific CVEs. #2408

Behavior Changes

• Pipenv will now parse & capitalize platform_python_implementation markers
  • This could cause an issue if you have an out of date Pipfile which lowercases the comparison value (e.g. cpython instead of CPython). #2123
• Pipenv will now only search for requirements.txt files when creating new projects, and during that time only if the user doesn't specify packages to pass in. #2309

Bug Fixes

• Massive internal improvements to requirements parsing codebase, resolver, and error messaging. #1962, #2186, #2263, #2312
• Pipenv will now parse & capitalize platform_python_implementation markers. #2123
• Fixed a bug with parsing and grouping old-style setup.py extras during resolution #2142
• Fixed a bug causing pipenv graph to throw unhelpful exceptions when running against empty or non-existent environments. #2161
• Fixed a bug which caused --system to incorrectly abort when users were in a virtualenv. #2181
• Removed vendored cacert.pem which could cause issues for some users with custom certificate settings. #2193
• Fixed a regression which led to direct invocations of virtualenv, rather than calling it by module. #2198
• Locking will now pin the correct VCS ref during pipenv update runs. Running pipenv update with a new vcs ref specified in the Pipfile will now properly obtain, resolve, and install the specified dependency at the specified ref. #2209
• pipenv clean will now correctly ignore comments from pip freeze when cleaning the environment. #2262
• Resolution bugs causing packages for incompatible python versions to be locked have been fixed. #2267
• Fixed a bug causing pipenv graph to fail to display sometimes. #2268
• Updated requirementslib to fix a bug in pipfile parsing affecting relative path conversions. #2269
• Windows executable discovery now leverages os.pathext. #2298
• Fixed a bug which caused --deploy --system to inadvertently create a virtualenv before failing. #2301
• Fixed an issue which led to a failure to unquote special characters in file and wheel paths. #2302
• VCS dependencies are now manually obtained only if they do not match the requested ref. #2304
• Added error handling functionality to properly cope with single-digit Requires-Python metatdata with no specifiers. #2377
• pipenv update will now always run the resolver and lock before ensuring your dependencies are in sync with your lockfile. #2379
• Resolved a bug in our patched resolvers which could cause nondeterministic resolution failures in certain conditions. Running pipenv install with no arguments in a project with only a Pipfile will now correctly lock first for dependency resolution before installing. #2384
• Patched python-dotenv to ensure that environment variables always get encoded to the filesystem encoding. #2386

Improved Documentation

• Update documentation wording to clarify Pipenv's overall role in the packaging ecosystem. #2194
• Added contribution documentation and guidelines. #2205
• Added instructions for supervisord compatibility. #2215
• Fixed broken links to development philosophy and contribution documentation. #2248

Vendored Libraries

• Removed vendored cacert.pem which could cause issues for some users with custom certificate settings. #2193

• Dropped vendored pip 9 and vendored, patched, and migrated to pip 10. Updated patched piptools version. #2255

• Updated requirementslib to fix a bug in pipfile parsing affecting relative path conversions. #2269

• Added custom shell detection library shellingham, a port of our changes to pew. #2363

• Patched python-dotenv to ensure that environment variables always get encoded to the filesystem encoding. #2386

• Updated vendored libraries. The following vendored libraries were updated:

  • distlib from version 0.2.6 to 0.2.7.
  • jinja2 from version 2.9.5 to 2.10.
  • pathlib2 from version 2.1.0 to 2.3.2.
  • parse from version 2.8.0 to 2.8.4.
  • pexpect from version 2.5.2 to 2.6.0.
  • requests from version 2.18.4 to 2.19.1.
  • idna from version 2.6 to 2.7.
  • certifi from version 2018.1.16 to 2018.4.16.
  • packaging from version 16.8 to 17.1.
  • six from version 1.10.0 to 1.11.0.
  • requirementslib from version 0.2.0 to 1.0.1.

  In addition, scandir was vendored and patched to avoid importing host system binaries when falling back to pathlib2. #2368
