# 2023.6.18 (2023-06-18)

## Bug Fixes

- Fixes resolver to only consider the default index for packages when a secondary index is not specified.  This brings the code into alignment with stated assumptions about index restricted packages behavior of `pipenv`.  [#5737](https://github.com/pypa/pipenv/issues/5737)

## Removals and Deprecations

- Deprecation of `--skip-lock` flag as it bypasses the security benefits of pipenv.  Plus it lacks proper deterministic support of installation from multiple package indexes.  [#5737](https://github.com/pypa/pipenv/issues/5737)

# 2023.4.20 (2023-04-20)

## Features & Improvements

- Checks environment variable `PIP_TRUSTED_HOSTS` when evaluating an
  index specified at the command line when adding to `Pipfile`.

  For example, this command line

  ```
  PIP_TRUSTED_HOSTS=internal.mycompany.com pipenv install pypkg --index=https://internal.mycompany.com/pypi/simple
  ```

  will add the following to the `Pipfile`:

  ```
  [[source]]
  url = 'https://internal.mycompany.com/pypi/simple'
  verify_ssl = false
  name = 'Internalmycompany'

  [packages]
  pypkg = {version="*", index="Internalmycompany"}
  ```

  This allows users with private indexes to add them to `Pipfile`
  initially from command line with correct permissions using environment
  variable `PIP_TRUSTED_HOSTS`.  [#5572](https://github.com/pypa/pipenv/issues/5572)

## Features & Improvements

- Provide a more powerful solution than `--keep-outdated` and `--selective-upgrade` which are deprecated for removal.
  Introducing the `pipenv upgrade` command which takes the same package specifiers as `pipenv install` and
  updates the `Pipfile` and `Pipfile.lock` with a valid lock resolution that only effects the specified packages and their dependencies.
  Additionally, the `pipenv update` command has been updated to use the `pipenv upgrade` routine when packages are provided, which will install sync the new lock file as well.  [#5617](https://github.com/pypa/pipenv/issues/5617)

## Vendored Libraries

- Bump vistir to 0.8.0, requirementslib to 2.2.4.  [#5635](https://github.com/pypa/pipenv/issues/5635)

# 2022.12.17 (2022-12-17)

## Bug Fixes

- virtualenv creation no longer uses `--creator=venv` by default; introduced two environment variables:
  `PIPENV_VIRTUALENV_CREATOR` -- May be specified to instruct virtualenv which `--creator=` to use.

# 2022.10.12 (2022-10-12)

## Improved Documentation

- Update pipenv docs for with example for callabale package functions in Pipfile scripts  [#5396](https://github.com/pypa/pipenv/issues/5396)

# 2022.10.11 (2022-10-11)

## Bug Fixes

- Revert decision to change the default isolation level because it caused problems with existing workflows; solution is to recommend users that have issues requiring pre-requisites to pass --extra-pip-args="--no-build-isolation" in their install or sync commands.  [#5399](https://github.com/pypa/pipenv/issues/5399)

# 2022.10.10 (2022-10-10)

## Features & Improvements

- Add ability for callable scripts in Pipfile under \[scripts\]. Callables can now be added like: `<pathed.module>:<func>` and can also take arguments. For example: `func = {call = "package.module:func('arg1', 'arg2')"}` then this can be activated in the shell with `pipenv run func`  [#5294](https://github.com/pypa/pipenv/issues/5294)

## Bug Fixes

- Fixes regression from `2022.10.9` where `Pipfile` with `pipenv` section began generating new hash,
  and also fix regression where lock phase did not update the hash value.  [#5394](https://github.com/pypa/pipenv/issues/5394)

# 2022.10.9 (2022-10-09)

## Behavior Changes

- New pipfiles show python_full_version under \[requires\] if specified. Previously creating a new pipenv project would only specify in the Pipfile the major and minor version, i.e. "python_version = 3.7". Now if you create a new project with a fully named python version it will record both in the Pipfile. So: "python_version = 3.7" and "python_full_version = 3.7.2"  [#5345](https://github.com/pypa/pipenv/issues/5345)

## Relates to dev process changes

- Silence majority of pytest.mark warnings by registering custom marks. Can view a list of custom marks by running `pipenv run pytest --markers`

# 2022.10.4 (2022-10-04)

# 2022.9.24 (2022-09-24)

## Bug Fixes

- Update `requirementslib==2.0.3` to always evaluate the requirement markers fresh (without lru_cache) to fix marker determinism issue.  [#4660](https://github.com/pypa/pipenv/issues/4660)

# 2022.9.21 (2022-09-21)

## Bug Fixes

- Fix regression to `install --skip-lock` with update to `plette`.  [#5368](https://github.com/pypa/pipenv/issues/5368)

# 2022.9.20 (2022-09-20)

## Behavior Changes

- Remove usage of pipfile module in favour of Plette.
  pipfile is not actively maintained anymore. Plette is actively maintained,
  and has stricter checking of the Pipefile and Pipefile.lock. As a result,
  Pipefile with unnamed package indices will fail to lock. If a Pipefile
  was hand crafeted, and the source is anonymous an error will be thrown.
  The solution is simple, add a name to your index, e.g, replace:

  ```
  [[source]]
  url = "https://pypi.acme.com/simple"
  verify_ssl = true
  ```

  With:

  ```
  [[source]]
  url = "https://pypi.acme.com/simple"
  verify_ssl = true
  name = acmes_private_index  `#5339 <https://github.com/pypa/pipenv/issues/5339>`_
  ```

# 2022.5.3.dev0 (2022-06-07)

## Bug Fixes

- Adjust pipenv to work with the newly added `venv` install scheme in Python.
  First check if `venv` is among the available install schemes, and use it if it is. Otherwise fall back to the `nt` or `posix_prefix` install schemes as before. This should produce no change for environments where the install schemes were not redefined.  [#5096](https://github.com/pypa/pipenv/issues/5096)

# 2022.5.2 (2022-05-02)

# 2022.4.20 (2022-04-20)

## Features & Improvements

- Added new Pipenv option `install_search_all_sources` that allows installation of packages from an
  existing `Pipfile.lock` to search all defined indexes for the constrained package version and hash signatures.  [#5041](https://github.com/pypa/pipenv/issues/5041)

  several reports of pipenv locking for an infinite amount of time when using certain package constraints.
  This also drops support for python 3.6 as it is EOL and support was removed in pip 22.x  [#4995](https://github.com/pypa/pipenv/issues/4995)

## Removals and Deprecations

- Removed the vendor dependency `more-itertools` as it was originally added for `zipp`, which since stopped using it.  [#5044](https://github.com/pypa/pipenv/issues/5044)
- Removed all usages of `pipenv.vendor.vistir.compat.fs_str`, since this function was used for PY2-PY3 compatibility and is no longer needed.  [#5062](https://github.com/pypa/pipenv/issues/5062)

  Unset variable maintains the existing behavior of preferring to use the project's `.venv` should it exist.  [#2763](https://github.com/pypa/pipenv/issues/2763)
- Fix an edge case of hash collection in index restricted packages whereby the hashes for some packages would
  be missing from the `Pipfile.lock` following package index restrictions added in `pipenv==2022.3.23`.  [#5023](https://github.com/pypa/pipenv/issues/5023)

## Improved Documentation

- Pipenv CLI documentation generation has been fixed.  It had broke when `click` was vendored into the project in
  `2021.11.9` because by default `sphinx-click` could no longer determine the CLI inherited from click.  [#4778](https://github.com/pypa/pipenv/issues/4778)
- Improve documentation around extra indexes and index restricted packages.  [#5022](https://github.com/pypa/pipenv/issues/5022)

## Removals and Deprecations

- Removes the optional `install` argument `--extra-index-url` as it was not compatible with index restricted packages.
  Using the `--index` argument is the correct way to specify a package should be pulled from the non-default index.  [#5022](https://github.com/pypa/pipenv/issues/5022)

## Relates to dev process changes

- Added code linting using pre-commit-hooks, black, flake8, isort, pygrep-hooks, news-fragments and check-manifest.
  Very similar to pip's configuration; adds a towncrier new's type `process` for change to Development processes.

# 2022.3.28 (2022-03-27)

## Bug Fixes

- Environment variables were not being loaded when the `--quiet` flag was set  [#5010](https://github.com/pypa/pipenv/issues/5010)
- It would appear that `requirementslib` was not fully specifying the subdirectory to `build_pep517` and
  and when a new version of `setuptools` was released, the test `test_lock_nested_vcs_direct_url`
  broke indicating the Pipfile.lock no longer contained the extra dependencies that should have been resolved.
  This regression affected `pipenv>=2021.11.9` but has been fixed by a patch to `requirementslib`.  [#5019](https://github.com/pypa/pipenv/issues/5019)

## Vendored Libraries

- Vendor in pip==21.2.4 (from 21.2.2) in order to bring in requested bug fix for python3.6.  Note: support for 3.6 will be dropped in a subsequent release.  [#5008](https://github.com/pypa/pipenv/issues/5008)

## Bug Fixes

- Fixes issue with new index safety restriction, whereby an unnamed extra sources index
  caused and error to be thrown during install.  [#5002](https://github.com/pypa/pipenv/issues/5002)
- The text `Loading .env environment variables...` has been switched back to stderr as to not
  break requirements.txt generation.  Also it only prints now when a `.env` file is actually present.  [#5003](https://github.com/pypa/pipenv/issues/5003)

# 2022.3.23 (2022-03-22)

## Features & Improvements

# 2020.5.28 (2020-05-28)

## Features & Improvements

- `pipenv install` and `pipenv sync` will no longer attempt to install satisfied dependencies during installation.  [#3057](https://github.com/pypa/pipenv/issues/3057),
  [#3506](https://github.com/pypa/pipenv/issues/3506)

- Added support for resolution of direct-url dependencies in `setup.py` files to respect `PEP-508` style URL dependencies.  [#3148](https://github.com/pypa/pipenv/issues/3148)

- Added full support for resolution of all dependency types including direct URLs, zip archives, tarballs, etc.

  - Improved error handling and formatting.
  - Introduced improved cross platform stream wrappers for better `stdout` and `stderr` consistency.  [#3298](https://github.com/pypa/pipenv/issues/3298)

- For consistency with other commands and the `--dev` option
  description, `pipenv lock --requirements --dev` now emits
  both default and development dependencies.
  The new `--dev-only` option requests the previous
  behaviour (e.g. to generate a `dev-requirements.txt` file).  [#3316](https://github.com/pypa/pipenv/issues/3316)

- Pipenv will now successfully recursively lock VCS sub-dependencies.  [#3328](https://github.com/pypa/pipenv/issues/3328)

- Added support for `--verbose` output to `pipenv run`.  [#3348](https://github.com/pypa/pipenv/issues/3348)

- Pipenv will now discover and resolve the intrinsic dependencies of **all** VCS dependencies, whether they are editable or not, to prevent resolution conflicts.  [#3368](https://github.com/pypa/pipenv/issues/3368)

- Added a new environment variable, `PIPENV_RESOLVE_VCS`, to toggle dependency resolution off for non-editable VCS, file, and URL based dependencies.  [#3577](https://github.com/pypa/pipenv/issues/3577)

- Added the ability for Windows users to enable emojis by setting `PIPENV_HIDE_EMOJIS=0`.  [#3595](https://github.com/pypa/pipenv/issues/3595)

- Allow overriding PIPENV_INSTALL_TIMEOUT environment variable (in seconds).  [#3652](https://github.com/pypa/pipenv/issues/3652)

- Allow overriding PIP_EXISTS_ACTION environment variable (value is passed to pip install).
  Possible values here: <https://pip.pypa.io/en/stable/reference/pip/#exists-action-option>
  Useful when you need to `PIP_EXISTS_ACTION=i` (ignore existing packages) - great for CI environments, where you need really fast setup.  [#3738](https://github.com/pypa/pipenv/issues/3738)

- Pipenv will no longer forcibly override `PIP_NO_DEPS` on all vcs and file dependencies as resolution happens on these in a pre-lock step.  [#3763](https://github.com/pypa/pipenv/issues/3763)

- Improved verbose logging output during `pipenv lock` will now stream output to the console while maintaining a spinner.  [#3810](https://github.com/pypa/pipenv/issues/3810)

- Added support for automatic python installs via `asdf` and associated `PIPENV_DONT_USE_ASDF` environment variable.  [#4018](https://github.com/pypa/pipenv/issues/4018)

- Pyenv/asdf can now be used whether or not they are available on PATH. Setting PYENV_ROOT/ASDF_DIR in a Pipenv's .env allows Pipenv to install an interpreter without any shell customizations, so long as pyenv/asdf is installed.  [#4245](https://github.com/pypa/pipenv/issues/4245)

- Added `--key` command line parameter for including personal PyUp.io API tokens when running `pipenv check`.  [#4257](https://github.com/pypa/pipenv/issues/4257)

## Behavior Changes

- Make conservative checks of known exceptions when subprocess returns output, so user won't see the whole traceback - just the error.  [#2553](https://github.com/pypa/pipenv/issues/2553)
- Do not touch Pipfile early and rely on it so that one can do `pipenv sync` without a Pipfile.  [#3386](https://github.com/pypa/pipenv/issues/3386)
- Re-enable `--help` option for `pipenv run` command.  [#3844](https://github.com/pypa/pipenv/issues/3844)
- Make sure `pipenv lock -r --pypi-mirror {MIRROR_URL}` will respect the pypi-mirror in requirements output.  [#4199](https://github.com/pypa/pipenv/issues/4199)

## Bug Fixes

# 2018.10.9 (2018-10-09)

## Features & Improvements

- Added environment variables `PIPENV_VERBOSE` and `PIPENV_QUIET` to control
  output verbosity without needing to pass options.  [#2527](https://github.com/pypa/pipenv/issues/2527)

- Updated test-PyPI add-on to better support json-API access (forward compatibility).
  Improved testing process for new contributors.  [#2568](https://github.com/pypa/pipenv/issues/2568)

- Greatly enhanced python discovery functionality:

  - Added pep514 (windows launcher/finder) support for python discovery.
  - Introduced architecture discovery for python installations which support different architectures.  [#2582](https://github.com/pypa/pipenv/issues/2582)

- Added support for `pipenv shell` on msys and cygwin/mingw/git bash for Windows.  [#2641](https://github.com/pypa/pipenv/issues/2641)

- Enhanced resolution of editable and VCS dependencies.  [#2643](https://github.com/pypa/pipenv/issues/2643)

- Deduplicate and refactor CLI to use stateful arguments and object passing.  See [this issue](https://github.com/pallets/click/issues/108) for reference.  [#2814](https://github.com/pypa/pipenv/issues/2814)

## Behavior Changes

- Virtual environment activation for `run` is revised to improve interpolation
  with other Python discovery tools.  [#2503](https://github.com/pypa/pipenv/issues/2503)
- Improve terminal coloring to display better in Powershell.  [#2511](https://github.com/pypa/pipenv/issues/2511)
- Invoke `virtualenv` directly for virtual environment creation, instead of depending on `pew`.  [#2518](https://github.com/pypa/pipenv/issues/2518)

- Add `COMSPEC` to fallback option (along with `SHELL` and `PYENV_SHELL`)
  if shell detection fails, improving robustness on Windows.  [#2651](https://github.com/pypa/pipenv/issues/2651)
- Fallback to shell mode if `run` fails with Windows error 193 to handle non-executable commands. This should improve usability on Windows, where some users run non-executable files without specifying a command, relying on Windows file association to choose the current command.  [#2718](https://github.com/pypa/pipenv/issues/2718)

  specific CVEs.  [#2408](https://github.com/pypa/pipenv/issues/2408)

## Behavior Changes

- Pipenv will now parse & capitalize `platform_python_implementation` markers
  .. warning:: This could cause an issue if you have an out of date `Pipfile`
  which lower-cases the comparison value (e.g. `cpython` instead of
  `CPython`).  [#2123](https://github.com/pypa/pipenv/issues/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](https://github.com/pypa/pipenv/issues/2309)

  than calling it by module.  [#2198](https://github.com/pypa/pipenv/issues/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`

  virtualenv before failing.  [#2301](https://github.com/pypa/pipenv/issues/2301)
- Fixed an issue which led to a failure to unquote special characters in file
  and wheel paths.  [#2302](https://github.com/pypa/pipenv/issues/2302)
- VCS dependencies are now manually obtained only if they do not match the
  requested ref.  [#2304](https://github.com/pypa/pipenv/issues/2304)
- Added error handling functionality to properly cope with single-digit
  `Requires-Python` metadata with no specifiers.  [#2377](https://github.com/pypa/pipenv/issues/2377)
- `pipenv update` will now always run the resolver and lock before ensuring
  dependencies are in sync with project Lockfile.  [#2379](https://github.com/pypa/pipenv/issues/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](https://github.com/pypa/pipenv/issues/2384)
- Patched `python-dotenv` to ensure that environment variables always get
  encoded to the filesystem encoding.  [#2386](https://github.com/pypa/pipenv/issues/2386)

## Improved Documentation

- Update documentation wording to clarify Pipenv's overall role in the packaging ecosystem.  [#2194](https://github.com/pypa/pipenv/issues/2194)
- Added contribution documentation and guidelines.  [#2205](https://github.com/pypa/pipenv/issues/2205)
- Added instructions for supervisord compatibility.  [#2215](https://github.com/pypa/pipenv/issues/2215)
- Fixed broken links to development philosophy and contribution documentation.  [#2248](https://github.com/pypa/pipenv/issues/2248)

## Vendored Libraries

- Removed vendored `cacert.pem` which could cause issues for some users with
  custom certificate settings.  [#2193](https://github.com/pypa/pipenv/issues/2193)

- Dropped vendored pip 9 and vendored, patched, and migrated to pip 10. Updated
  patched piptools version.  [#2255](https://github.com/pypa/pipenv/issues/2255)

- Updated `requirementslib` to fix a bug in Pipfile parsing affecting
  relative path conversions.  [#2269](https://github.com/pypa/pipenv/issues/2269)

- Added custom shell detection library `shellingham`, a port of our changes
  to `pew`.  [#2363](https://github.com/pypa/pipenv/issues/2363)

- Patched `python-dotenv` to ensure that environment variables always get
  encoded to the filesystem encoding.  [#2386](https://github.com/pypa/pipenv/issues/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`.
