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. (#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. (#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. (#906)

Stop breaking when given pip commands in uppercase (#1559, #1725)

pip wheel now returns an error code if any wheels fail to build. (#1769)
pip wheel wasn't building wheels for dependencies of editable requirements. (#1775)
Allow the use of --no-use-wheel within a requirements file. (#1859)

Allow the use of OS standard user configuration files instead of ones simply based around $HOME. (#2021)
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)
Use a randomized and secure default build directory when possible. (#1964, #1935, #676, #2122, CVE-2014-8991)
Support environment markers in requirements.txt files. (#1433, #2134)

Added support for --no-index in requirements files.
Added "pip show" command to get information about an installed package. Thanks Kelsey Hightower and Rafael Caricio. (#131)

Allow package URLS to have querystrings. Thanks W. Trevor King. (#504)
pip freeze now falls back to non-editable format rather than blowing up if it can't determine the origin repository of an editable. Thanks Rory McCann. (#58)
Added a __main__.py file to enable python -m pip on Python versions that support it. Thanks Alexey Luchko.
Fixed upgrading from VCS url of project that does exist on index. Thanks Andrew Knapp for the report. (#487)
Fix upgrade from VCS url of project with no distribution on index. Thanks Andrew Knapp for the report. (#486)
Add a clearer error message on a malformed VCS url. Thanks Thomas Fenzl. (#427)

Errors from subprocesses will display the current working directory. Thanks Antti Kaihola.
Fixed compatibility with Subversion 1.7. Thanks Qiangning Hong. Note that setuptools remains incompatible with Subversion 1.7; to get the benefits of pip's support you must use Distribute rather than setuptools. (#369)

pip install -U no longer reinstalls the same versions of packages. Thanks iguananaut for the pull request. (#49)
Removed -E/--environment option and PIP_RESPECT_VIRTUALENV; both use a restart-in-venv mechanism that's broken, and neither one is useful since every virtualenv now has pip inside it. Replace pip -E path/to/venv install Foo with virtualenv path/to/venv && path/to/venv/pip install Foo.

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)

Fixed uninstallation on Windows
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.

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.

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.

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.

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.

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.

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.
Fixed small problem that prevented using pip.py without actually installing pip.
