   ### 20.2
   ```
   =================

Deprecations and Removals
-------------------------

- Deprecate setup.py-based builds that do not generate an ``.egg-info`` directory. (`6998 &lt;https://github.com/pypa/pip/issues/6998&gt;`_, `8617 &lt;https://github.com/pypa/pip/issues/8617&gt;`_)
- Disallow passing install-location-related arguments in ``--install-options``. (`7309 &lt;https://github.com/pypa/pip/issues/7309&gt;`_)
- Add deprecation warning for invalid requirements format &quot;base&gt;=1.0[extra]&quot; (`8288 &lt;https://github.com/pypa/pip/issues/8288&gt;`_)
- Deprecate legacy setup.py install when building a wheel failed for source
  distributions without pyproject.toml (`8368 &lt;https://github.com/pypa/pip/issues/8368&gt;`_)
- Deprecate -b/--build/--build-dir/--build-directory. Its current behaviour is confusing
  and breaks in case different versions of the same distribution need to be built during
  the resolution process. Using the TMPDIR/TEMP/TMP environment variable, possibly
  combined with --no-clean covers known use cases. (`8372 &lt;https://github.com/pypa/pip/issues/8372&gt;`_)
- Remove undocumented and deprecated option ``--always-unzip`` (`8408 &lt;https://github.com/pypa/pip/issues/8408&gt;`_)

Features
--------

- Log debugging information about pip, in ``pip install --verbose``. (`3166 &lt;https://github.com/pypa/pip/issues/3166&gt;`_)
- Refine error messages to avoid showing Python tracebacks when an HTTP error occurs. (`5380 &lt;https://github.com/pypa/pip/issues/5380&gt;`_)
- Install wheel files directly instead of extracting them to a temp directory. (`6030 &lt;https://github.com/pypa/pip/issues/6030&gt;`_)
- Add a beta version of pip&#39;s next-generation dependency resolver.

  Move pip&#39;s new resolver into beta, remove the
  ``--unstable-feature=resolver`` flag, and enable the
  ``--use-feature=2020-resolver`` flag. The new resolver is
  significantly stricter and more consistent when it receives
  incompatible instructions, and reduces support for certain kinds of
  :ref:`Constraints Files`, so some workarounds and workflows may
  break. More details about how to test and migrate, and how to report
  issues, at :ref:`Resolver changes 2020` . Maintainers are preparing to
   ```
   
  
  
   ### 20.2b1
   ```
   ===================

Bug Fixes
---------

- Correctly treat wheels containing non-ASCII file contents so they can be
  installed on Windows. (`5712 &lt;https://github.com/pypa/pip/issues/5712&gt;`_)
- Prompt the user for password if the keyring backend doesn&#39;t return one (`7998 &lt;https://github.com/pypa/pip/issues/7998&gt;`_)

Improved Documentation
----------------------

- Add GitHub issue template for reporting when the dependency resolver fails (`8207 &lt;https://github.com/pypa/pip/issues/8207&gt;`_)
