* **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`.
