HISTORY.txt

2018.7.1:
 - All calls to `pipenv shell` are now implemented from the ground up using `shellingham`,
   a custom library which was purpose built to handle edge cases and shell detection.
 - Added support for python 3.7 via a few small compatibility / bugfixes.
 - Added new flag `pipenv --support` to replace the diagnostic command `python -m
   pipenv.help`.
 - Improved import times and CLI runtimes with minor tweaks.
 - Fixed an ongoing bug which sometimes resolved incompatible versions into lockfiles.
 - Fixed a bug which caused errors when creating virtualenvs which contained leading dash
   characters.
 - Fixed a logic error which caused `--deploy --system` to overwrite editable vcs packages
   in the pipfile before installing, which caused any installation to fail by default.
 - Installed new vendored jinja2 templates for `click-completion` which were causing
   template errors for users with completion enabled.
 - Pipenv will now ensure that its internal package names registry files are written with
   unicode strings.
 - Fixed a bug causing requirements input as relative paths to be output as absolute paths
   or URIs.
 - Fixed a bug affecting normalization of `git+git@host` uris.
 - Pipenv will now always use `pathlib2` for `Path` based filesystem interactions by
   default on `python<3.5`.
 - Fixed a bug which prevented passing proxy PyPI indexes set with `--pypi-mirror` from
   being passed to pip during virtualenv creation, which could cause the creation to
   freeze in some cases.
 - Using the `python -m pipenv.help` command will now use proper encoding for the host
   filesystem to avoid encoding issues.
 - The new `jinja2` templates for `click_completion` will now be included in pipenv source
   distributions.
 - Resolved a long-standing issue with re-using previously generated `InstallRequirement`
   objects for resolution which could cause `PKG-INFO` file information to be deleted,
   raising a `TypeError`.
 - Resolved an issue parsing usernames from private PyPI URIs in `Pipfiles` by updating
   `requirementslib`.
 - Updated requirementslib to fix an issue with properly quoting markers in VCS requirements.
 - Add patch to `prettytoml` to support Python 3.7.
 - Patched `prettytoml.AbstractTable._enumerate_items` to handle `StopIteration` errors in
   preparation of release of python 3.7.
 - Fixed an issue reading package names from `setup.py` files in projects which imported
   utilities such as `versioneer`.
 - Updated `requirementslib` to version `1.0.9`
 - Unraveled a lot of old, unnecessary patches to `pip-tools` which were causing
   non-deterministic resolution errors.
2018.6.25:
 - Added error handling functionality to properly cope with single-digit `Requires-Python`
   metatdata with no specifiers.
 - Pipenv will now generate hashes much more quickly by resolving them in a single pass
   during locking.
 - `pipenv run` will now avoid spawning additional `COMSPEC` instances to run commands in
   when possible.
 - `pipenv check` now may take multiple of the additional argument `--ignore` which takes
   a parameter `cve_id` for the purpose of ignoring specific CVEs.
 - Patched `python-dotenv` to ensure that environment variables always get encoded to the
   filesystem encoding.
 - Virtualenv names will now appear in prompts for most Windows users.
 - Resolver runtime and caching has been improved.
 - Improved virtualenv discovery when using `pipenv --venv`.
 - Improved error messages when failing to activate virtualenvs.
 - Dependency resolver reliability has been improved.
 - Added nested JSON output to the `pipenv graph` command.
 - Added support for mounted drives via UNC paths.
 - Added support for Windows Subsystem for Linux bash shell detection.
 - Added custom shell detection library `shellingham`, a port of our changes to `pew`.
 - Requirements are only auto-imported in new projects created without passing any packages
   to install and without an initial Pipfile.
 - Added support for cmder shell paths with spaces.
 - Dropped vendored pip 9 and vendor, patch, and migrate to pip 10.
 - Virtualenv activation lines will now avoid being written to some shell history files.
 - 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.)
 - Lock and update VCS dependencies properly by checking them out and cloning them
   manually before installing and generating a lockfile to guarantee dependencies are
   locked.
 - 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.
 - 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.
 - Pipenv will now parse & capitalize`platform_python_implementation` markers -- **note** this
   could cause an issue if you have an out of date Pipfile which lowercases the comparison
   value (e.g. `cpython` instead of `CPython`).
 - Massive internal improvements to requirements parsing codebase, resolver, and error
   messaging.
 - Fixed a regression which led to direct invocations of `virtualenv`, rather than calling
   it by module.
 - Resolution bugs causing packages for incompatible python versions to be locked
   have been fixed.
 - VCS dependencies are now manually obtained only if they do not match the requested ref.
 - Windows executable discovery now leverages `os.pathext`.
 - Pipenv will now correctly unqoute special characters in wheel URIs.
 - Fixed a bug with parsing and grouping old-style setup.py extras during resolution.
 - Fixed a bug which caused `--system` to incorrectly abort when users were in a virtualenv.
 - Pipenv clean will now ignore comments when cleaning the environment.
 - Fixed a bug which caused `--deploy --system` to inadvertently create a virtualenv
   before failing.
 - Errors when running `pipenv graph` running against empty or non-existent environments.
   will now contain helpful information.
 - Removed vendored `cacert.pem` which could cause issues for some users with custom
   certificate settings.
 - Updated requirementslib to fix a bug in pipfile parsing affecting relative path conversions on Windows.
