**8.1.2 (unreleased)**
* Fix a regression on systems with uninitialized locale (:issue:`3575`).
* Use environment markers to filter packages before determining if a
required wheel is supported. Solves (:issue:`3254`).
**8.1.1 (2016-03-17)**
* Fix regression with non-ascii requirement files on Python 2 and add support
for encoding headers in requirement files (:issue:`3548`, :pull:`3547`).
**8.1.0 (2016-03-05)**
* Implement PEP 513, which adds support for the manylinux1 platform tag,
allowing carefully compiled binary wheels to be installed on compatible Linux
platforms.
* Allow wheels which are not specific to a particular Python interpreter but
which are specific to a particular platform (:issue:`3202`).
* Fixed an issue where ``call_subprocess`` would crash trying to print debug
data on child process failure (:issue:`3521`, :pull:`3522`).
* Exclude the wheel package from the `pip freeze` output (like pip and setuptools).
:issue:`2989`.
* Allow installing modules from a subdirectory of a vcs repository
in non-editable mode (:issue:`3217`, :pull:`3466`).
* Make pip wheel and pip download work with vcs urls with subdirectory option
(:pull:`3466`).
* Show classifiers in ``pip show``.
* Show PEP376 Installer in ``pip show`` (:issue:`3517`).
* Unhide completion command (:pull:`1810`).
* Show latest version number in ``pip search`` results (:pull:`1415`).
* Decode requirement files according to their BOM if present (:pull:`3485`,
:issue:`2865`).
* Fix and deprecate package name detection from url path (:issue:`3523` and
:pull:`3495`).
* Correct the behavior where interpreter specific tags (such as cp34) were
being used on later versions of the same interprter instead of only for that
specific interpreter (:issue:`3472`).
* Fix an issue where pip would erroneously install a 64 bit wheel on a 32 bit
Python running on a 64 bit OS X machine.
* Do not assume that all git repositories have an origin remote.
* Correctly display the line to add to a requirements.txt for an URL based
dependency when ``--require-hashes`` is enabled.
**8.0.3 (2016-02-25)**
* Make ``install --quiet`` really quiet. See :issue:`3418`.
* Fix a bug when removing packages in python 3: disable INI-style parsing of the
entry_point.txt file to allow entry point names with colons (:pull:`3434`)
* Normalize generated script files path in RECORD files. (:pull:`3448`)
* Fix bug introduced in 8.0.0 where subcommand output was not shown,
even when the user specified ``-v`` / ``--verbose``. :issue:`3486`.
* Enable python -W with respect to PipDeprecationWarning. (:pull:`3455`)
* Upgrade distlib to 0.2.2 (fix :issue:`3467`):
* Improved support for Jython when quoting executables in output scripts.
* Add a `--all` option to `pip freeze` to include usually skipped package
(like pip, setuptools and wheel) to the freeze output. :issue:`1610`.
**8.0.2 (2016-01-21)**
* Stop attempting to trust the system CA trust store because it's extremely
common for them to be broken, often in incompatible ways. See :pull:`3416`.
**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).
* Upgrading a distutils installed item that is installed outside of a virtual
environment, while inside of a virtual environment will no longer warn or
error.
* Fix a bug where pre-releases were showing up in ``pip list --outdated``
without the ``--pre`` flag.
* Switch the SOABI emulation from using RuntimeWarnings to debug logging.
* Rollback the removal of the ability to uninstall distutils installed items
until a future date.
**8.0.0 (2016-01-19)**
* **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/--uptodate.
(: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`).

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`).

* Upgrade packaging to 15.3.
* Normalize post-release spellings for rev/r prefixes.

* Changed ScriptMaker to work better under Jython.
* Upgrade ipaddress to 1.0.13.
**7.1.0 (2015-06-30)**

* Fixed an issue where ``--user`` could not be used when ``--prefix`` was used
in a distutils configuration file.
* Fixed an issue where the SOABI tags were not correctly being generated on
Python 3.5.
* Fixed an issue where we were advising windows users to upgrade by directly
executing pip, when that would always fail on Windows.
* Allow ``~`` to be expanded within a cache directory in all situations.
**7.0.3 (2015-06-01)**
* Fixed a regression where ``--no-cache-dir`` would raise an exception, fixes
:issue:`2855`.
**7.0.2 (2015-06-01)**
* **BACKWARD INCOMPATIBLE** Revert the change (released in v7.0.0) that
required quoting in requirements files around specifiers containing
environment markers. (:pull:`2841`)
* **BACKWARD INCOMPATIBLE** Revert the accidental introduction of support for
options interleaved with requirements, version specifiers etc in
``requirements`` files. (:pull:`2841`)
* Expand ``~`` in the cache directory when caching wheels, fixes :issue:`2816`.

* Don't build and cache wheels for non-editable installations from VCSs.
* Allow ``--allow-all-external`` inside of a requirements.txt file, fixing a
regression in 7.0.
**7.0.0 (2015-05-21)**
* **BACKWARD INCOMPATIBLE** Removed the deprecated ``--mirror``,
``--use-mirrors``, and ``-M`` options.
* **BACKWARD INCOMPATIBLE** Removed the deprecated ``zip`` and ``unzip``
commands.
* **BACKWARD INCOMPATIBLE** Removed the deprecated ``--no-install`` and
``--no-download`` options.
* **BACKWARD INCOMPATIBLE** No longer implicitly support an insecure origin
origin, and instead require insecure origins be explicitly trusted with the
``--trusted-host`` option.
* **BACKWARD INCOMPATIBLE** Removed the deprecated link scraping that attempted
to parse HTML comments for a specially formatted comment.
* **BACKWARD INCOMPATIBLE** Requirements in requirements files containing
markers must now be quoted due to parser changes from (:pull:`2697`) and
(:pull:`2725`). For example, use ``"SomeProject; python_version < '2.7'"``,
not simply ``SomeProject; python_version < '2.7'``
* `get-pip.py` now installs the "wheel" package, when it's not already installed
(:pull:`2800`).

Fixes :issue:`497`
* Support ``--install-option`` and ``--global-option`` per requirement in
requirement files (:pull:`2537`)

directory to speed up subsequent installs. (:pull:`2618`)
* Allow fine grained control over the use of wheels and source builds.
(:pull:`2699`)
* ``--no-use-wheel`` and ``--use-wheel`` are deprecated in favour of new
options ``--no-binary`` and ``--only-binary``. The equivalent of
``--no-use-wheel`` is ``--no-binary=:all:``. (:pull:`2699`)

disable the use of wheels, and the autobuilding of wheels. (:pull:`2711`)
Fixes :issue:`2677`
* Improve logging when a requirement marker doesn't match your environment
(:pull:`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`` (:pull:`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 (:pull:`2766`).
* Display a warning when attempting to access a repository that uses HTTPS when
we don't have Python compiled with SSL support (:pull:`2761`).
* Allowing using extras when installing from a file path without requiring the
use of an editable (:pull:`2785`).
* Fix an infinite loop when the cache directory is stored on a file system
which does not support hard links (:pull:`2796`).
* Remove the implicit debug log that was written on every invocation, instead
users will need to use ``--log`` if they wish to have one (:pull:`2798`).
**6.1.1 (2015-04-07)**
* No longer ignore dependencies which have been added to the standard library,
instead continue to install them.
**6.1.0 (2015-04-07)**
* Fixes :issue:`2502`. Upgrades were failing when no potential links were found
for dependencies other than the current installation. (:pull:`2538`)
* Use a smoother progress bar when the terminal is capable of handling it,
otherwise fallback to the original ASCII based progress bar.
* Display much less output when `pip install` succeeds, because on success,
users probably don't care about all the nitty gritty details of compiling and
installing. When `pip install` fails, display the failed install output once
instead of twice, because once is enough. (:pull:`2487`)
* Upgrade the bundled copy of requests to 2.6.0, fixing CVE-2015-2296.
* Display format of latest package when using ``pip list --outdated``.

(:pull:`2636`, :pull:`2602`)
* Support arch specific wheels that are not tied to a specific Python ABI.
(:pull:`2561`)
* Output warnings and errors to stderr instead of stdout. (:pull:`2543`)
* Adjust the cache dir file checks to only check ownership if the effective
user is root. (:pull:`2396`)

the root directory when inside of a virtual environment. (:pull:`2421`)
**6.0.8 (2015-02-04)**
* Fix an issue where the ``--download`` flag would cause pip to no longer use
randomized build directories.
* Fix an issue where pip did not properly unquote quoted URLs which contain
characters like PEP 440's epoch separator (``!``).
* Fix an issue where distutils installed projects were not actually uninstalled
and deprecate attempting to uninstall them altogether.
* Retry deleting directories incase a process like an antivirus is holding the
directory open temporarily.
* Fix an issue where pip would hide the cursor on Windows but would not reshow
it.
**6.0.7 (2015-01-28)**
* Fix a regression where Numpy requires a build path without symlinks to
properly build.
* Fix a broken log message when running ``pip wheel`` without a requirement.
* Don't mask network errors while downloading the file as a hash failure.
* Properly create the state file for the pip version check so it only happens
once a week.

project without a normalized version.
**6.0.6 (2015-01-03)**
* Continue the regression fix from 6.0.5 which was not a complete fix.
**6.0.5 (2015-01-03)**
* Fix a regression with 6.0.4 under Windows where most commands would raise an
exception due to Windows not having the ``os.geteuid()`` function.
**6.0.4 (2015-01-03)**
* Fix an issue where ANSI escape codes would be used on Windows even though the
Windows shell does not support them, causing odd characters to appear with
the progress bar.
* 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.
* Fix a regression where the ``-q`` flag would not properly suppress the
display of the progress bars.
**6.0.3 (2014-12-23)**
* Fix an issue where the implicit version check new in pip 6.0 could cause pip
to block for up to 75 seconds if PyPI was not accessible.
* Make ``--no-index`` imply ``--disable-pip-version-check``.
**6.0.2 (2014-12-23)**
* Fix an issue where the output saying that a package was installed would
report the old version instead of the new version during an upgrade.
* Fix left over merge conflict markers in the documentation.
* Document the backwards incompatible PEP 440 change in the 6.0.0 changelog.
**6.0.1 (2014-12-22)**
* Fix executable file permissions for Wheel files when using the distutils
scripts option.
* Fix a confusing error message when an exceptions was raised at certain
points in pip's execution.
* Fix the missing list of versions when a version cannot be found that matches
the specifiers.
* Add a warning about the possibly problematic use of > when the given
specifier doesn't match anything.
* Fix an issue where installing from a directory would not copy over certain
directories which were being excluded, however some build systems rely on
them.
**6.0 (2014-12-22)**
* **PROCESS** Version numbers are now simply ``X.Y`` where the leading ``1``
has been dropped.
* **BACKWARD INCOMPATIBLE** Dropped support for Python 3.1.
* **BACKWARD INCOMPATIBLE** Removed the bundle support which was deprecated in
1.4. (:pull:`1806`)
* **BACKWARD INCOMPATIBLE** File lists generated by `pip show -f` are now
rooted at the location reported by show, rather than one (unstated)
directory lower. (:pull:`1933`)
* **BACKWARD INCOMPATIBLE** The ability to install files over the FTP protocol
was accidentally lost in pip 1.5 and it has now been decided to not restore
that ability.
* **BACKWARD INCOMPATIBLE** PEP 440 is now fully implemented, this means that
in some cases versions will sort differently or version specifiers will be
interpreted differently than previously. The common cases should all function
similarly to before.
* **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. See
:issue:`906` for discussion.
* **DEPRECATION** Implicitly accessing URLs which point to an origin which is
not a secure origin, instead requiring an opt-in for each host using the new
``--trusted-host`` flag (``pip install --trusted-host example.com foo``).
* Allow the new ``--trusted-host`` flag to also disable TLS verification for
a particular hostname.
* Added a ``--user`` flag to ``pip freeze`` and ``pip list`` to check the
user site directory only.

freeze` (:pull:`1606`, :pull:`1369`)
* Fixed :issue:`1424`. Add ``--client-cert`` option for SSL client certificates.
* Fixed :issue:`1484`. `pip show --files` was broken for wheel installs. (:pull:`1635`)
* Fixed :issue:`1641`. install_lib should take precedence when reading distutils config.
(:pull:`1642`)
* Send `Accept-Encoding: identity` when downloading files in an attempt to
convince some servers who double compress the downloaded file to stop doing
so. (:pull:`1688`)
* Fixed :issue:`1559`. Stop breaking when given pip commands in uppercase (:pull:`1725`)
* Fixed :issue:`1618`. Pip no longer adds duplicate logging consumers, so it
won't create duplicate output when being called multiple times. (:pull:`1723`)
* Fixed :issue:`1769`. `pip wheel` now returns an error code if any wheels
fail to build.
* Fixed :issue:`1775`. `pip wheel` wasn't building wheels for dependencies of
editable requirements.
* Allow the use of ``--no-use-wheel`` within a requirements file. (:pull:`1859`)
* Fixed :issue:`1680`. Attempt to locate system TLS certificates to use instead
of the included CA Bundle if possible. (:pull:`1866`)
* Fixed :issue:`1319`. Allow use of Zip64 extension in Wheels and other zip
files. (:pull:`1868`)
* Fixed :issue:`1101`. Properly handle an index or --find-links target which
has a <base> without a href attribute. (:pull:`1869`)
* Fixed :issue:`1885`. Properly handle extras when a project is installed
via Wheel. (:pull:`1896`)
* Fixed :issue:`1180`. Added support to respect proxies in ``pip search``. It
also fixes :issue:`932` and :issue:`1104`. (:pull:`1902`)
* Fixed :issue:`798` and :issue:`1060`. `pip install --download` works with vcs links.
(:pull:`1926`)
* Fixed :issue:`1456`. Disabled warning about insecure index host when using localhost.
Based off of Guy Rozendorn's work in :pull:`1718`. (:pull:`1967`)
* Allow the use of OS standard user configuration files instead of ones simply
based around ``$HOME``. (:pull:`2021`)
* Fixed :issue:`1825`. When installing directly from wheel paths or urls,
previous versions were not uninstalled. This also fixes :issue:`804`
specifically for the case of wheel archives. (:pull:`1838`)
* Fixed :issue:`2075`, 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. (:pull:`2076`)
* Fixed :issue:`1964`, :issue:`1935`, :issue:`676`, Use a randomized and secure
default build directory when possible. (:pull:`2122`, CVE-2014-8991)
* Fixed :issue:`1433`. Support environment markers in requirements.txt files.
(:pull:`2134`)
* Automatically retry failed HTTP requests by default. (:pull:`1444`, :pull:`2147`)

* Upgrade the bundled projects (distlib==0.1.8, html5lib==1.0b3, six==1.6.1,
colorama==0.3.1, setuptools==3.4.4).
**1.5.4 (2014-02-21)**
* Correct deprecation warning for ``pip install --build`` to only notify when
the `--build` value is different than the default.
**1.5.3 (2014-02-20)**
* **DEPRECATION** ``pip install --build`` and ``pip install --no-clean`` are now
deprecated. See :issue:`906` for discussion.
* Fixed :issue:`1112`. Couldn't download directly from wheel paths/urls, and when wheel

* Fixed an error that prevented accessing PyPI when pyopenssl, ndg-httpsclient,
and pyasn1 are installed

part of the URL in a requirements file
**1.5.1 (2014-01-20)**
* pip now only requires setuptools (any setuptools, not a certain version) when
installing distributions from src (i.e. not from wheel). (:pull:`1434`).
* `get-pip.py` now installs setuptools, when it's not already installed
(:pull:`1475`)
* Don't decode downloaded files that have a ``Content-Encoding`` header.
(:pull:`1435`)
* Fix to correctly parse wheel filenames with single digit versions.
(:pull:`1445`)
* If `--allow-unverified` is used assume it also means `--allow-external`.
(:pull:`1457`)
**1.5 (2014-01-01)**
* **BACKWARD INCOMPATIBLE** pip no longer supports the ``--use-mirrors``,
``-M``, and ``--mirrors`` flags. The mirroring support has been removed. In
order to use a mirror specify it as the primary index with ``-i`` or
``--index-url``, or as an additional index with ``--extra-index-url``. (:pull:`1098`, CVE-2013-5123)
* **BACKWARD INCOMPATIBLE** pip no longer will scrape insecure external urls by
default nor will it install externally hosted files by default. Users may opt
into installing externally hosted or insecure files or urls using
``--allow-external PROJECT`` and ``--allow-unverified PROJECT``. (:pull:`1055`)
* **BACKWARD INCOMPATIBLE** pip no longer respects dependency links by default.
Users may opt into respecting them again using ``--process-dependency-links``.

--no-download`` are now formally deprecated. See :issue:`906` for discussion on
possible alternatives, or lack thereof, in future releases.
* **DEPRECATION** ``pip zip`` and ``pip unzip`` are now formally deprecated.
* pip will now install Mac OSX platform wheels from PyPI. (:pull:`1278`)

installing wheels. (:pull:`1251`)
* Pip now confirms a wheel is supported when installing directly from a path or
url. (:pull:`1315`)
* Fixed :issue:`1097`, ``--ignore-installed`` now behaves again as designed, after it was
unintentionally broke in v0.8.3 when fixing :issue:`14` (:pull:`1352`).
* Fixed a bug where global scripts were being removed when uninstalling --user
installed packages (:pull:`1353`).
* Fixed :issue:`1163`, --user wasn't being respected when installing scripts from wheels (:pull:`1176`).

* Fixed :issue:`772`, error when setting PIP_EXISTS_ACTION (:pull:`1201`).
* Added colors to the logging output in order to draw attention to important
warnings and errors. (:pull:`1109`)

* Added support for installing packages from a subdirectory using the ``subdirectory``
editable option. ( :pull:`1082` )
* Fixed :issue:`1192`. "TypeError: bad operand type for unary" in some cases when
installing wheels using --find-links (:pull:`1218`).
* Fixed :issue:`1133` and :issue:`317`. Archive contents are now written based on system
defaults and umask (i.e. permissions are not preserved), except that regular
files with any execute permissions have the equivalent of "chmod +x" applied
after being written (:pull:`1146`).
* PreviousBuildDirError now returns a non-zero exit code and prevents the
previous build dir from being cleaned in all cases (:pull:`1162`).
* Renamed --allow-insecure to --allow-unverified, however the old name will
continue to work for a period of time (:pull:`1257`).
* Fixed :issue:`1006`, error when installing local projects with symlinks in
Python 3. (:pull:`1311`)
* The previously hidden ``--log-file`` otion, is now shown as a general option.
(:pull:`1316`)
**1.4.1 (2013-08-07)**
* **New Signing Key** Release 1.4.1 is using a different key than normal with
fingerprint: 7C6B 7C5D 5E2B 6356 A926 F04F 6E3C BCE9 3372 DCFA

**1.4 (2013-07-23)**
* **BACKWARD INCOMPATIBLE** pip now only installs stable versions by default,
and offers a new ``--pre`` option to also find pre-release and development
versions. (:pull:`834`)
* **BACKWARD INCOMPATIBLE** Dropped support for Python 2.5. The minimum
supported Python version for pip 1.4 is Python 2.6.
* Added support for installing and building wheel archives.
Thanks Daniel Holth, Marcus Smith, Paul Moore, and Michele Lacchia
(:pull:`845`)
* Applied security patch to pip's ssl support related to certificate DNS
wildcard matching (http://bugs.python.org/issue17980).
* To satisfy pip's setuptools requirement, pip now recommends setuptools>=0.8,
not distribute. setuptools and distribute are now merged into one project
called 'setuptools'. (:pull:`1003`)
* pip will now warn when installing a file that is either hosted externally to
the index or cannot be verified with a hash. In the future pip will default
to not installing them and will require the flags --allow-external NAME, and
--allow-insecure NAME respectively. (:pull:`985`)
* If an already-downloaded or cached file has a bad hash, re-download it rather
than erroring out. (:issue:`963`).
* ``pip bundle`` and support for installing from pybundle files is now
considered deprecated and will be removed in pip v1.5.
* Fixed a number of issues (:issue:`413`, :issue:`709`, :issue:`634`, :issue:`602`, and :issue:`939`) related to
cleaning up and not reusing build directories. (:pull:`865`, :issue:`948`)

Thanks Hugo Lopes Tavares and Kelsey Hightower (:pull:`872`).
* "Vendorized" distlib as pip.vendor.distlib (https://distlib.readthedocs.org/).
* Fixed git VCS backend with git 1.8.3. (:pull:`967`)
**1.3.1 (2013-03-08)**
* Fixed a major backward incompatible change of parsing URLs to externally
hosted packages that got accidentily included in 1.3.
**1.3 (2013-03-07)**
* SSL Cert Verification; Make https the default for PyPI access.
Thanks James Cleveland, Giovanni Bajo, Marcus Smith and many others (:pull:`791`, CVE-2013-1629).
* Added "pip list" for listing installed packages and the latest version
available. Thanks Rafael Caricio, Miguel Araujo, Dmitry Gladkov (:pull:`752`)
* Fixed security issues with pip's use of temp build directories.
Thanks David (d1b) and Thomas Guttler. (:pull:`780`, CVE-2013-1888)
* Improvements to sphinx docs and cli help. (:pull:`773`)
* Fixed :issue:`707`, dealing with OS X temp dir handling, which was causing
global NumPy installs to fail. (:pull:`768`)
* Split help output into general vs command-specific option groups.
Thanks Georgi Valkov. (:pull:`744`; :pull:`721` contains preceding refactor)
* Fixed dependency resolution when installing from archives with uppercase
project names. (:pull:`724`)
* Fixed problem where re-installs always occurred when using file:// find-links.
(Pulls :issue:`683`/:issue:`702`)
* "pip install -v" now shows the full download url, not just the archive name.
Thanks Marc Abramowitz (:pull:`687`)
* Fix to prevent unnecessary PyPI redirects. Thanks Alex Gronholm (:pull:`695`)
* Fixed :issue:`670` - install failure under Python 3 when the same version
of a package is found under 2 different URLs. Thanks Paul Moore (:pull:`671`)
* Fix git submodule recursive updates. Thanks Roey Berman. (Pulls :issue:`674`)
* Explicitly ignore rel='download' links while looking for html pages.
Thanks Maxime R. (:pull:`677`)
* --user/--upgrade install options now work together. Thanks 'eevee' for
discovering the problem. (:pull:`705`)
* Added check in ``install --download`` to prevent re-downloading if the target
file already exists. Thanks Andrey Bulgakov. (:pull:`669`)
* Added support for bare paths (including relative paths) as argument to
`--find-links`. Thanks Paul Moore for draft patch.
* Added support for --no-index in requirements files.
* Added "pip show" command to get information about an installed package.
Fixes :issue:`131`. Thanks Kelsey Hightower and Rafael Caricio.
* Added `--root` option for "pip install" to specify root directory. Behaves
like the same option in distutils but also plays nice with pip's egg-info.
Thanks Przemek Wrzos. (:issue:`253` / :pull:`693`)
**1.2.1 (2012-09-06)**
