Released v8.0.0 * **BACKWARD INCOMPATIBLE** Drop support for Python 3.2. * **BACKWARD INCOMPATIBLE** Remove the ability to find any files other than the ones directly linked from the index or find-links pages. * **BACKWARD INCOMPATIBLE** Remove the ``--download-cache`` which had been deprecated and no-op'd in 6.0. * **BACKWARD INCOMPATIBLE** Remove the ``--log-explicit-levels`` which had been deprecated in 6.0. * **BACKWARD INCOMPATIBLE** Change pip wheel --wheel-dir default path from <cwd>/wheelhouse to <cwd>. * Deprecate and no-op the ``--allow-external``, ``--allow-all-external``, and ``--allow-unverified`` functionality that was added as part of PEP 438. With changes made to the repository protocol made in PEP 470, these options are no longer functional. * Allow ``--trusted-host`` within a requirements file. :issue:`2822`. * Allow ``--process-dependency-links`` within a requirements file. :issue:`1274`. * Allow ``--pre`` within a requirements file. :issue:`1273`. * Allow repository URLs with secure transports to count as trusted. (E.g., "git+ssh" is okay.) :issue:`2811`. * Implement a top-level ``pip download`` command and deprecate ``pip install --download``. * Fixed :issue:`3141`, when uninstalling, look for the case of paths containing symlinked directories (:pull:`3154`) * When installing, if building a wheel fails, clear up the build directory before falling back to a source install. :issue:`3047`. * Fix user directory expansion when ``HOME=/``. Workaround for Python bug http://bugs.python.org/issue14768, reported in :issue:`2996`. * Fixed :issue:`3009`, correct reporting of requirements file line numbers (:pull:`3125`) * Fixed :issue:`1062`, Exception(IOError) for ``pip freeze`` and ``pip list`` commands with subversion >= 1.7. (:pull:`3346`) * Provide a spinner showing that progress is happening when installing or building a package via ``setup.py``. This will alleviate concerns that projects with unusually long build times have with pip appearing to stall. * Include the functionality of ``peep`` into pip, allowing hashes to be baked into a requirements file and ensuring that the packages being downloaded match one of those hashes. This is an additional, opt-in security measure that, when used, removes the need to trust the repository. * Fix a bug causing pip to not select a wheel compiled against an OSX SDK later than what Python itself was compiled against when running on a newer version of OSX. * Add a new ``--prefix`` option for ``pip install`` that supports wheels and sdists. (:pull:`3252`) * Fixed :issue:`2042` regarding wheel building with setup.py using a different encoding than the system. * Drop PasteScript specific egg_info hack. (:pull:`3270`) * Allow combination of pip list options --editable with --outdated/--updtodate. (:issue:`933`) * Gives VCS implementations control over saying whether a project is under their control (:pull:`3258`) * Git detection now works when ``setup.py`` is not at the Git repo root and when ``package_dir`` is used, so ``pip freeze`` works in more cases (:pull:`3258`) * Correctly freeze Git develop packages in presence of the &subdirectory option (:pull:`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 (:pull:`3258`) * Add the ``--prefix`` flag to ``pip install`` which allows specifying a root prefix to use instead of ``sys.prefix`` (:pull:`3252`). * Allow duplicate specifications in the case that only the extras differ, and union all specified extras together (:pull:`3198`). * Fix the detection of the user's current platform on OSX when determining the OSX SDK version (:pull:`3232`). * Prevent the automatically built wheels from mistakenly being used across multiple versions of Python when they may not be correctly configured for that by making the wheel specific to a specific version of Python and specific interpreter (:pull:`3225`). * Emulate the SOABI support in wheels from Python 2.x on Python 2.x as closely as we can with the information available within the interpreter (:pull:`3075`). * Don't roundtrip to the network when git is pinned to a specific commit hash and that hash already exists locally (:pull:`3066`). * Prefer wheels built against a newer SDK to wheels built against an older SDK on OSX (:pull:`3163`). * Show entry points for projects installed via wheel (:pull:`3122`). * Improve message when an unexisting path is passed to --find-links option (:issue:`2968`). * pip freeze does not add the VCS branch/tag name in the #egg=... fragment anymore (:pull:`3312`). * Warn on installation of editable if the provided #egg=name part does not match the metadata produced by `setup.py egg_info`. :issue:`3143`. * Add support for .xz files for python versions supporting them (>= 3.3). :issue:`722`.
