20.0.2 (2020-01-24)

Bug Fixes

  • Fix a regression in generation of compatibility tags. (#7626)

Vendored Libraries

  • Upgrade packaging to 20.1

20.0.1 (2020-01-21)

Bug Fixes

  • Rename an internal module, to avoid ImportErrors due to improper uninstallation. (#7621)

20.0 (2020-01-21)

Process

  • Switch to a dedicated CLI tool for vendoring dependencies.

Deprecations and Removals

  • Remove wheel tag calculation from pip and use packaging.tags. This should provide more tags ordered better than in prior releases. (#6908)
  • Deprecate setup.py-based builds that do not generate an .egg-info directory. (#6998)
  • The pip>=20 wheel cache is not retro-compatible with previous versions. Until pip 21.0, pip will continue to take advantage of existing legacy cache entries. (#7296)
  • Deprecate undocumented --skip-requirements-regex option. (#7297)
  • Deprecate passing install-location-related options via --install-option. (#7309)
  • Use literal "abi3" for wheel tag on CPython 3.x, to align with PEP 384 which only defines it for this platform. (#7327)
  • Remove interpreter-specific major version tag e.g. cp3-none-any from consideration. This behavior was not documented strictly, and this tag in particular is not useful. Anyone with a use case can create an issue with pypa/packaging. (#7355)
  • Wheel processing no longer permits wheels containing more than one top-level .dist-info directory. (#7487)
  • Support for the git+git@ form of VCS requirement is being deprecated and will be removed in pip 21.0. Switch to git+https:// or git+ssh://. git+git:// also works but its use is discouraged as it is insecure. (#7543)

Features

  • Default to doing a user install (as if --user was passed) when the main site-packages directory is not writeable and user site-packages are enabled. (#1668)
  • Warn if a path in PATH starts with tilde during pip install. (#6414)
  • Cache wheels built from Git requirements that are considered immutable, because they point to a commit hash. (#6640)
  • Add option --no-python-version-warning to silence warnings related to deprecation of Python versions. (#6673)
  • Cache wheels that pip wheel built locally, matching what pip install does. This particularly helps performance in workflows where pip wheel is used for building before installing. Users desiring the original behavior can use pip wheel --no-cache-dir. (#6852)
  • Display CA information in pip debug. (#7146)
  • Show only the filename (instead of full URL), when downloading from PyPI. (#7225)
  • Suggest a more robust command to upgrade pip itself to avoid confusion when the current pip command is not available as pip. (#7376)
  • Define all old pip console script entrypoints to prevent import issues in stale wrapper scripts. (#7498)
  • The build step of pip wheel now builds all wheels to a cache first, then copies them to the wheel directory all at once. Before, it built them to a temporary directory and moved them to the wheel directory one by one. (#7517)
  • Expand ~ prefix to user directory in path options, configs, and environment variables. Values that may be either URL or path are not currently supported, to avoid ambiguity:
    • --find-links
    • --constraint, -c
    • --requirement, -r
    • --editable, -e (#980)

Bug Fixes

  • Correctly handle system site-packages, in virtual environments created with venv (PEP 405). (#5702, #7155)
  • Fix case sensitive comparison of pip freeze when used with -r option. (#5716)
  • Enforce PEP 508 requirement format in pyproject.toml build-system.requires. (#6410)
  • Make ensure_dir() also ignore ENOTEMPTY as seen on Windows. (#6426)
  • Fix building packages which specify backend-path in pyproject.toml. (#6599)
  • Do not attempt to run setup.py clean after a pep517 build error, since a setup.py may not exist in that case. (#6642)
  • Fix passwords being visible in the index-url in "Downloading <url>" message. (#6783)
  • Change method from shutil.remove to shutil.rmtree in noxfile.py. (#7191)
  • Skip running tests which require subversion, when svn isn't installed (#7193)
  • Fix not sending client certificates when using --trusted-host. (#7207)
  • Make sure pip wheel never outputs pure python wheels with a python implementation tag. Better fix/workaround for #3025 by using a per-implementation wheel cache instead of caching pure python wheels with an implementation tag in their name. (#7296)
  • Include subdirectory URL fragments in cache keys. (#7333)
  • Fix typo in warning message when any of --build-option, --global-option and --install-option is used in requirements.txt (#7340)
  • Fix the logging of cached HTTP response shown as downloading. (#7393)
  • Effectively disable the wheel cache when it is not writable, as is the case with the http cache. (#7488)
  • Correctly handle relative cache directory provided via --cache-dir. (#7541)

19.3 (2019-10-14)

Deprecations and Removals

  • Remove undocumented support for un-prefixed URL requirements pointing to SVN repositories. Users relying on this can get the original behavior by prefixing their URL with svn+ (which is backwards-compatible). (#7037)
  • Remove the deprecated --venv option from pip config. (#7163)

Features

  • Print a better error message when --no-binary or --only-binary is given an argument starting with -. (#3191)

  • A custom (JSON-encoded) string can now be added to pip's User-Agent using the PIP_USER_AGENT_USER_DATA environment variable. (#5549)
  • For consistency, passing --no-cache-dir no longer affects whether wheels will be built. In this case, a temporary directory is used. (#5749)
  • Command arguments in subprocess log messages are now quoted using shlex.quote(). (#6290)
  • Prefix warning and error messages in log output with WARNING and ERROR. (#6298)
  • Using --build-options in a PEP 517 build now fails with an error, rather than silently ignoring the option. (#6305)

  • Fix incorrect URL quoting of IPv6 addresses. (#6285)
  • Redact the password from the extra index URL when using pip -v. (#6295)
  • The spinner no longer displays a completion message after subprocess calls not needing a spinner. It also no longer incorrectly reports an error after certain subprocess calls to Git that succeeded. (#6312)
  • Fix the handling of editable mode during installs when pyproject.toml is present but PEP 517 doesn't require the source tree to be treated as pyproject.toml-style. (#6370)

  • Fix a regression introduced in 19.0.2 where the filename in a RECORD file of an installed file would not be updated when installing a wheel. (#6266)

19.0.2 (2019-02-09)

Bug Fixes

  • Fix a crash where PEP 517-based builds using --no-cache-dir would fail in some circumstances with an AssertionError due to not finalizing a build directory internally. (#6197)
  • Provide a better error message if attempting an editable install of a directory with a pyproject.toml but no setup.py. (#6170)
  • The implicit default backend used for projects that provide a pyproject.toml file without explicitly specifying build-backend now behaves more like direct execution of setup.py, and hence should restore compatibility with projects that were unable to be installed with pip 19.0. This raised the minimum required version of setuptools for such builds to 40.8.0. (#6163)
  • Allow RECORD lines with more than three elements, and display a warning. (#6165)
  • AdjacentTempDirectory fails on unwritable directory instead of locking up the uninstall command. (#6169)
  • Make failed uninstalls roll back more reliably and better at avoiding naming conflicts. (#6194)
  • Ensure the correct wheel file is copied when building PEP 517 distribution is built. (#6196)
  • The Python 2 end of life warning now only shows on CPython, which is the implementation that has announced end of life plans. (#6207)

Improved Documentation

  • Re-write README and documentation index (#5815)

19.0.1 (2019-01-23)

Bug Fixes

  • Remove the deprecated SVN editable detection based on dependency links during freeze. (#5866)

Features

  • Implement PEP 517 (allow projects to specify a build backend via pyproject.toml). (#5743)
  • Implement manylinux2010 platform tag support. manylinux2010 is the successor to manylinux1. It allows carefully compiled binary wheels to be installed on compatible Linux platforms. (#5008)
  • Improve build isolation: handle .pth files, so namespace packages are correctly supported under Python 3.2 and earlier. (#5656)
  • Include the package name in a freeze warning if the package is not installed. (#5943)
  • Warn when dropping an --[extra-]index-url value that points to an existing local directory. (#5827)

  • Canonicalize sdist file names so they can be matched to a canonicalized package name passed to pip install. (#5870)
  • Properly decode special characters in SVN URL credentials. (#5968)
  • Make PIP_NO_CACHE_DIR disable the cache also for truthy values like "true", "yes", "1", etc. (#5735)

18.1 (2018-10-05)

Features

  • Allow PEP 508 URL requirements to be used as dependencies.

    As a security measure, pip will raise an exception when installing packages from PyPI if those packages depend on packages not also hosted on PyPI. In the future, PyPI will block uploading packages with such external URL dependencies directly. (#4187)

  • Allows dist options (--abi, --python-version, --platform, --implementation) when installing with --target (#5355)

  • Support passing svn+ssh URLs with a username to pip install -e. (#5375)

  • pip now ensures that the RECORD file is sorted when installing from a wheel file. (#5525)

Improved Documentation

18.0 (2018-07-22)

Process

  • Switch to a Calendar based versioning scheme.
  • Formally document our deprecation process as a minimum of 6 months of deprecation warnings.
  • Adopt and document NEWS fragment writing style.
  • Switch to releasing a new, non-bug fix version of pip every 3 months.

Deprecations and Removals

  • Remove the legacy format from pip list. (#3651, #3654)

  • Dropped support for Python 3.3. (#3796)

  • Remove support for cleaning up #egg fragment postfixes. (#4174)

  • Remove the shim for the old get-pip.py location. (#5520)

    For the past 2 years, it's only been redirecting users to use the newer https://bootstrap.pypa.io/get-pip.py location.

Features

  • Introduce a new --prefer-binary flag, to prefer older wheels over newer source packages. (#3785)
  • Improve autocompletion function on file name completion after options which have <file>, <dir> or <path> as metavar. (#4842, #5125)
  • Add support for installing PEP 518 build dependencies from source. (#5229)
  • Improve status message when upgrade is skipped due to only-if-needed strategy. (#5319)

Bug Fixes

  • Update pip's self-check logic to not use a virtualenv specific file and honor cache-dir. (#3905)

  • Remove compiled pyo files for wheel packages. (#4471)

  • Speed up printing of newly installed package versions. (#5127)

  • Restrict install time dependency warnings to directly-dependant packages. (#5196, #5457)

    Warning about the entire package set has resulted in users getting confused as to why pip is printing these warnings.

  • Improve handling of PEP 518 build requirements: support environment markers and extras. (#5230, #5265)

  • Remove username/password from log message when using index with basic auth. (#5249)

  • Remove trailing os.sep from PATH directories to avoid false negatives. (#5293)

  • Fix "pip wheel pip" being blocked by the "don't use pip to modify itself" check. (#5311, #5312)

  • Disable pip's version check (and upgrade message) when installed by a different package manager. (#5346)

    This works better with Linux distributions where pip's upgrade message may result in users running pip in a manner that modifies files that should be managed by the OS's package manager.

  • Check for file existence and unlink first when clobbering existing files during a wheel install. (#5366)

  • Improve error message to be more specific when no files are found as listed in as listed in PKG-INFO. (#5381)

  • Always read pyproject.toml as UTF-8. This fixes Unicode handling on Windows and Python 2. (#5482)

  • Fix a crash that occurs when PATH not set, while generating script location warning. (#5558)

Deprecations and Removals

  • Removed the deprecated --egg parameter to pip install. (#1749)
  • Removed support for uninstalling projects which have been installed using distutils. distutils installed projects do not include metadata indicating what files belong to that install and thus it is impossible to actually uninstall them rather than just remove the metadata saying they've been installed while leaving all of the actual files behind. (#2386)
  • Removed the deprecated --download option to pip install. (#2643)
  • Removed the deprecated --(no-)use-wheel flags to pip install and pip wheel. (#2699)
  • Removed the deprecated --allow-external, --allow-all-external, and --allow-unverified options. (#3070)

  • pip now retries on more HTTP status codes, for intermittent failures. Previously, it only retried on the standard 503. Now, it also retries on 500 (transient failures on AWS S3), 520 and 527 (transient failures on Cloudflare). (#4473)
  • pip now displays where it is looking for packages, if non-default locations are used. (#4483)

  • Avoid importing setuptools in the parent pip process, to avoid a race condition when upgrading one of setuptools dependencies. (#4264)
  • Fix for an incorrect freeze warning message due to a package being included in multiple requirements files that were passed to freeze. Instead of warning incorrectly that the package is not installed, pip now warns that the package was declared multiple times and lists the name of each requirements file that contains the package in question. (#4293)
  • Generalize help text for compile/no-compile flags. (#4316)
  • Handle the case when /etc is not readable by the current user by using a hardcoded list of possible names of release files. (#4320)

8.0.1 (2016-01-21)

  • Detect CAPaths in addition to CAFiles on platforms that provide them.
  • Installing argparse or wsgiref will no longer warn or error - pip will allow the installation even though it may be useless (since the installed thing will be shadowed by the standard library).

  • Correctly freeze Git develop packages in presence of the &subdirectory option (#3258)
  • The detection of editable packages now relies on the presence of .egg-link instead of looking for a VCS, so pip list -e is more reliable. (#3258)
  • Add the --prefix flag to pip install which allows specifying a root prefix to use instead of sys.prefix. (#3252)
  • Allow duplicate specifications in the case that only the extras differ, and union all specified extras together. (#3198)
  • Fix the detection of the user's current platform on OSX when determining the OSX SDK version. (#3232)

  • Improve logging when a requirement marker doesn't match your environment. (#2735)
  • Removed the temporary modifications (that began in pip v1.4 when distribute and setuptools merged) that allowed distribute to be considered a conflict to setuptools. pip install -U setuptools will no longer upgrade "distribute" to "setuptools". Instead, use pip install -U distribute. (#2767)
  • Only display a warning to upgrade pip when the newest version is a final release and it is not a post release of the version we already have installed. (#2766)

  • Fix an issue where using -v would cause an exception saying TypeError: not all arguments converted during string formatting.
  • Fix an issue where using -v with dependency links would cause an exception saying TypeError: 'InstallationCandidate' object is not iterable.
  • Fix an issue where upgrading distribute would cause an exception saying TypeError: expected string or buffer.
  • Show a warning and disable the use of the cache directory when the cache directory is not owned by the current user, commonly caused by using sudo without the -H flag.
  • Update PEP 440 support to handle the latest changes to PEP 440, particularly the changes to >V and <V so that they no longer imply !=V.*.
  • Document the default cache directories for each operating system.
  • Create the cache directory when the pip version check needs to save to it instead of silently logging an error.

  • DEPRECATION pip install --download-cache and pip wheel --download-cache command line flags have been deprecated and the functionality removed. Since pip now automatically configures and uses it's internal HTTP cache which supplants the --download-cache the existing options have been made non functional but will still be accepted until their removal in pip v8.0. For more information please see https://pip.pypa.io/en/stable/reference/pip_install.html#caching
  • DEPRECATION pip install --build and pip install --no-clean are now NOT deprecated. This reverses the deprecation that occurred in v1.5.3. (#906)

  • When installing directly from wheel paths or urls, previous versions were not uninstalled. (#1825, #804, #1838)
  • Detect the location of the .egg-info directory by looking for any file located inside of it instead of relying on the record file listing a directory. (#2075, #2076)

1.0 (2011-04-04)

  • Added Python 3 support! Huge thanks to Vinay Sajip, Vitaly Babiy, Kelsey Hightower, and Alex Gronholm, among others.

    This may have to be run as root.

    Note

    Make sure you have distribute installed before using the installer!

  • Fixed egg name not properly resolving. Thanks Igor Sobreira. (#163)
  • Fixed Non-alphabetical installation of requirements. Thanks Igor Sobreira. (#178)

  • Fixed checking out the correct tag/branch/commit when updating an editable Git requirement. (#32, #150, #161)

  • Added ability to install version control requirements without making them editable, e.g.:

    pip install git+https://github.com/pypa/pip/

    (#49)

  • Correctly locate build and source directory on macOS. (#175)

  • Added git+https:// scheme to Git VCS backend.

0.8

  • Track which build/ directories pip creates, never remove directories it doesn't create. From Hugo Lopes Tavares.
  • pip now accepts file:// index URLs. Thanks Dave Abrahams.
  • Various cleanup to make test-running more consistent and less fragile. Thanks Dave Abrahams.
  • Real Windows support (with passing tests). Thanks Dave Abrahams.
  • pip-2.7 etc. scripts are created (Python-version specific scripts)
  • contrib/build-standalone script creates a runnable .zip form of pip, from Jannis Leidel
  • Editable git repos are updated when reinstalled
  • Fix problem with --editable when multiple .egg-info/ directories are found.
  • A number of VCS-related fixes for pip freeze, from Hugo Lopes Tavares.
  • Significant test framework changes, from Hugo Lopes Tavares.

0.7.2

  • Set zip_safe=False to avoid problems some people are encountering where pip is installed as a zip file.

0.7.1

  • Fixed opening of logfile with no directory name. Thanks Alexandre Conrad.
  • Temporary files are consistently cleaned up, especially after installing bundles, also from Alex Conrad.
  • Tests now require at least ScriptTest 1.0.3.

0.7

  • Fixed uninstallation on Windows
  • Added pip search command.
  • Tab-complete names of installed distributions for pip uninstall.
  • Support tab-completion when there is a global-option before the subcommand.
  • Install header files in standard (scheme-default) location when installing outside a virtualenv. Install them to a slightly more consistent non-standard location inside a virtualenv (since the standard location is a non-writable symlink to the global location).
  • pip now logs to a central location by default (instead of creating pip-log.txt all over the place) and constantly overwrites the file in question. On Unix and macOS this is '$HOME/.pip/pip.log' and on Windows it's '%HOME%\\pip\\pip.log'. You are still able to override this location with the $PIP_LOG_FILE environment variable. For a complete (appended) logfile use the separate '--log' command line option.
  • Fixed an issue with Git that left an editable package as a checkout of a remote branch, even if the default behaviour would have been fine, too.
  • Fixed installing from a Git tag with older versions of Git.
  • Expand "~" in logfile and download cache paths.
  • Speed up installing from Mercurial repositories by cloning without updating the working copy multiple times.
  • Fixed installing directly from directories (e.g. pip install path/to/dir/).
  • Fixed installing editable packages with svn+ssh URLs.
  • Don't print unwanted debug information when running the freeze command.
  • Create log file directory automatically. Thanks Alexandre Conrad.
  • Make test suite easier to run successfully. Thanks Dave Abrahams.
  • Fixed "pip install ." and "pip install .."; better error for directory without setup.py. Thanks Alexandre Conrad.
  • Support Debian/Ubuntu "dist-packages" in zip command. Thanks duckx.
  • Fix relative --src folder. Thanks Simon Cross.
  • Handle missing VCS with an error message. Thanks Alexandre Conrad.
  • Added --no-download option to install; pairs with --no-install to separate download and installation into two steps. Thanks Simon Cross.
  • Fix uninstalling from requirements file containing -f, -i, or --extra-index-url.
  • Leftover build directories are now removed. Thanks Alexandre Conrad.

0.6.3

  • Fixed import error on Windows with regard to the backwards compatibility package

0.6.2

  • Fixed uninstall when /tmp is on a different filesystem.
  • Fixed uninstallation of distributions with namespace packages.

0.6.1

  • Added support for the https and http-static schemes to the Mercurial and ftp scheme to the Bazaar backend.
  • Fixed uninstallation of scripts installed with easy_install.
  • Fixed an issue in the package finder that could result in an infinite loop while looking for links.
  • Fixed issue with pip bundle and local files (which weren't being copied into the bundle), from Whit Morriss.

0.6

  • Add pip uninstall and uninstall-before upgrade (from Carl Meyer).
  • Extended configurability with config files and environment variables.
  • Allow packages to be upgraded, e.g., pip install Package==0.1 then pip install Package==0.2.
  • Allow installing/upgrading to Package==dev (fix "Source version does not match target version" errors).
  • Added command and option completion for bash and zsh.
  • Extended integration with virtualenv by providing an option to automatically use an active virtualenv and an option to warn if no active virtualenv is found.
  • Fixed a bug with pip install --download and editable packages, where directories were being set with 0000 permissions, now defaults to 755.
  • Fixed uninstallation of easy_installed console_scripts.
  • Fixed uninstallation on macOS Framework layout installs
  • Fixed bug preventing uninstall of editables with source outside venv.
  • Creates download cache directory if not existing.

0.5.1

  • Fixed a couple little bugs, with git and with extensions.

0.5

  • Added ability to override the default log file name (pip-log.txt) with the environmental variable $PIP_LOG_FILE.
  • Made the freeze command print installed packages to stdout instead of writing them to a file. Use simple redirection (e.g. pip freeze > stable-req.txt) to get a file with requirements.
  • Fixed problem with freezing editable packages from a Git repository.
  • Added support for base URLs using <base href='...'> when parsing HTML pages.
  • Fixed installing of non-editable packages from version control systems.
  • Fixed issue with Bazaar's bzr+ssh scheme.
  • Added --download-dir option to the install command to retrieve package archives. If given an editable package it will create an archive of it.
  • Added ability to pass local file and directory paths to --find-links, e.g. --find-links=file:///path/to/my/private/archive
  • Reduced the amount of console log messages when fetching a page to find a distribution was problematic. The full messages can be found in pip-log.txt.
  • Added --no-deps option to install ignore package dependencies
  • Added --no-index option to ignore the package index (PyPI) temporarily
  • Fixed installing editable packages from Git branches.
  • Fixes freezing of editable packages from Mercurial repositories.
  • Fixed handling read-only attributes of build files, e.g. of Subversion and Bazaar on Windows.
  • When downloading a file from a redirect, use the redirected location's extension to guess the compression (happens specifically when redirecting to a bitbucket.org tip.gz file).
  • Editable freeze URLs now always use revision hash/id rather than tip or branch names which could move.
  • Fixed comparison of repo URLs so incidental differences such as presence/absence of final slashes or quoted/unquoted special characters don't trigger "ignore/switch/wipe/backup" choice.
  • Fixed handling of attempt to checkout editable install to a non-empty, non-repo directory.

0.4

  • Make -e work better with local hg repositories
  • Construct PyPI URLs the exact way easy_install constructs URLs (you might notice this if you use a custom index that is slash-sensitive).
  • Improvements on Windows (from Ionel Maries Cristian).
  • Fixed problem with not being able to install private git repositories.
  • Make pip zip zip all its arguments, not just the first.
  • Fix some filename issues on Windows.
  • Allow the -i and --extra-index-url options in requirements files.
  • Fix the way bundle components are unpacked and moved around, to make bundles work.
  • Adds -s option to allow the access to the global site-packages if a virtualenv is to be created.
  • Fixed support for Subversion 1.6.

0.3.1

  • Improved virtualenv restart and various path/cleanup problems on win32.
  • Fixed a regression with installing from svn repositories (when not using -e).
  • Fixes when installing editable packages that put their source in a subdirectory (like src/).
  • Improve pip -h

0.3

  • Added support for editable packages created from Git, Mercurial and Bazaar repositories and ability to freeze them. Refactored support for version control systems.
  • Do not use sys.exit() from inside the code, instead use a return. This will make it easier to invoke programmatically.
  • Put the install record in Package.egg-info/installed-files.txt (previously they went in site-packages/install-record-Package.txt).
  • Fix a problem with pip freeze not including -e svn+ when an svn structure is peculiar.
  • Allow pip -E to work with a virtualenv that uses a different version of Python than the parent environment.
  • Fixed Win32 virtualenv (-E) option.
  • Search the links passed in with -f for packages.
  • Detect zip files, even when the file doesn't have a .zip extension and it is served with the wrong Content-Type.
  • Installing editable from existing source now works, like pip install -e some/path/ will install the package in some/path/. Most importantly, anything that package requires will also be installed by pip.
  • Add a --path option to pip un/zip, so you can avoid zipping files that are outside of where you expect.
  • Add --simulate option to pip zip.

0.2.1

  • Fixed small problem that prevented using pip.py without actually installing pip.
  • Fixed --upgrade, which would download and appear to install upgraded packages, but actually just reinstall the existing package.
  • Fixed Windows problem with putting the install record in the right place, and generating the pip script with Setuptools.
  • Download links that include embedded spaces or other unsafe characters (those characters get %-encoded).
  • Fixed use of URLs in requirement files, and problems with some blank lines.
  • Turn some tar file errors into warnings.

0.2

  • Renamed to pip, and to install you now do pip install PACKAGE
  • Added command pip zip PACKAGE and pip unzip PACKAGE. This is particularly intended for Google App Engine to manage libraries to stay under the 1000-file limit.
  • Some fixes to bundles, especially editable packages and when creating a bundle using unnamed packages (like just an svn repository without #egg=Package).

0.1.4

  • Added an option --install-option to pass options to pass arguments to setup.py install
  • .svn/ directories are no longer included in bundles, as these directories are specific to a version of svn -- if you build a bundle on a system with svn 1.5, you can't use the checkout on a system with svn 1.4. Instead a file svn-checkout.txt is included that notes the original location and revision, and the command you can use to turn it back into an svn checkout. (Probably unpacking the bundle should, maybe optionally, recreate this information -- but that is not currently implemented, and it would require network access.)
  • Avoid ambiguities over project name case, where for instance MyPackage and mypackage would be considered different packages. This in particular caused problems on Macs, where MyPackage/ and mypackage/ are the same directory.
  • Added support for an environmental variable $PIP_DOWNLOAD_CACHE which will cache package downloads, so future installations won't require large downloads. Network access is still required, but just some downloads will be avoided when using this.

0.1.3

  • Always use svn checkout (not export) so that tag_svn_revision settings give the revision of the package.
  • Don't update checkouts that came from .pybundle files.

0.1.2

  • Improve error text when there are errors fetching HTML pages when seeking packages.
  • Improve bundles: include empty directories, make them work with editable packages.
  • If you use -E env and the environment env/ doesn't exist, a new virtual environment will be created.
  • Fix dependency_links for finding packages.

0.1.1

  • Fixed a NameError exception when running pip outside of a virtualenv environment.
  • Added HTTP proxy support (from Prabhu Ramachandran)
  • Fixed use of hashlib.md5 on python2.5+ (also from Prabhu Ramachandran)

0.1

  • Initial release
