================
- **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``.
(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``. (1055)
- **BACKWARD INCOMPATIBLE** pip no longer respects dependency links by default.
Users may opt into respecting them again using ``--process-dependency-links``.
- **DEPRECATION** ``pip install --no-install`` and ``pip install
--no-download`` are now formally deprecated. See 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`)
- pip now generates the appropriate platform-specific console scripts when
installing wheels. (1251)
- pip now confirms a wheel is supported when installing directly from a path or
url. (1315)
- ``--ignore-installed`` now behaves again as designed, after it was
unintentionally broke in v0.8.3 when fixing 14. (1097, 1352)
- Fixed a bug where global scripts were being removed when uninstalling --user
installed packages. (1353)
- ``--user`` wasn't being respected when installing scripts from wheels.
(1163, 1176)
- Assume '_' means '-' in versions from wheel filenames. (1150, 1158)
- Error when using --log with a failed install. (219, 1205)
- Fixed logging being buffered and choppy in Python 3. (1131)
- Don't ignore --timeout. (70, 1202)
- Fixed an error when setting PIP_EXISTS_ACTION. (772, 1201)
- Added colors to the logging output in order to draw attention to important
warnings and errors. (1109)
- Added warnings when using an insecure index, find-link, or dependency link.
(1121)
- Added support for installing packages from a subdirectory using the
``subdirectory`` editable option. (1082)
- Fixed "TypeError: bad operand type for unary" in some cases when installing
wheels using --find-links. (1192, 1218)
- 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.
(1133, 317, 1146)
- PreviousBuildDirError now returns a non-zero exit code and prevents the
previous build dir from being cleaned in all cases. (1162)
- Renamed --allow-insecure to --allow-unverified, however the old name will
continue to work for a period of time. (1257)
- Fixed an error when installing local projects with symlinks in Python 3.
(1006, 1311)
- The previously hidden ``--log-file`` option, is now shown as a general option.
