0.26.0

======
- Fix multiple entrypoint comparison failure on Python 3 (Issue 148)

0.25.0

======
- Add Python 3.5 to tox configuration
- Deterministic (sorted) metadata
- Fix tagging for Python 3.5 compatibility
- Support py2-none-'arch' and py3-none-'arch' tags
- Treat data-only wheels as pure
- Write to temporary file and rename when using wheel install --force

0.24.0

======
- The python tag used for pure-python packages is now .pyN (major version
only). This change actually occurred in 0.23.0 when the --python-tag
option was added, but was not explicitly mentioned in the changelog then.
- wininst2wheel and egg2wheel removed. Use "wheel convert [archive]"
instead.
- Wheel now supports setuptools style conditional requirements via the
extras_require={} syntax. Separate 'extra' names from conditions using
the : character. Wheel's own setup.py does this. (The empty-string
extra is the same as install_requires.) These conditional requirements
should work the same whether the package is installed by wheel or
by setup.py.

0.23.0

======
- Compatibility tag flags added to the bdist_wheel command
- sdist should include files necessary for tests
- 'wheel convert' can now also convert unpacked eggs to wheel
- Rename pydist.json to metadata.json to avoid stepping on the PEP
- The --skip-scripts option has been removed, and not generating scripts is now
the default. The option was a temporary approach until installers could
generate scripts themselves. That is now the case with pip 1.5 and later.
Note that using pip 1.4 to install a wheel without scripts will leave the
installation without entry-point wrappers. The "wheel install-scripts"
command can be used to generate the scripts in such cases.
- Thank you contributors

0.22.0

======
- Include entry_points.txt, scripts a.k.a. commands, in experimental
pydist.json
- Improved test_requires parsing
- Python 2.6 fixes, "wheel version" command courtesy pombredanne

0.21.0

======
- Pregenerated scripts are the default again.
- "setup.py bdist_wheel --skip-scripts" turns them off.
- setuptools is no longer a listed requirement for the 'wheel'
package. It is of course still required in order for bdist_wheel
to work.
- "python -m wheel" avoids importing pkg_resources until it's necessary.

0.20.0

======
- No longer include console_scripts in wheels. Ordinary scripts (shell files,
standalone Python files) are included as usual.
- Include new command "python -m wheel install-scripts [distribution
[distribution ...]]" to install the console_scripts (setuptools-style
scripts using pkg_resources) for a distribution.

0.19.0

======
- pymeta.json becomes pydist.json

0.18.0

======
- Python 3 Unicode improvements

0.17.0

======
- Support latest PEP-426 "pymeta.json" (json-format metadata)

0.16.0

======
- Python 2.6 compatibility bugfix (thanks John McFarlane)
- Non-prerelease version number

0.15.0

======
- Various improvements

0.14.0

======
- Changed the signature format to better comply with the current JWS spec.
Breaks all existing signatures.
- Include ``wheel unsign`` command to remove RECORD.jws from an archive.
- Put the description in the newly allowed payload section of PKG-INFO
(METADATA) files.

0.13.0

======
- Use distutils instead of sysconfig to get installation paths; can install
headers.
- Improve WheelFile() sort.
- Allow bootstrap installs without any pkg_resources.

0.12.0

======
- Unit test for wheel.tool.install

0.11.0

======
- API cleanup

0.10.3

======
- Scripts fixer fix

0.10.2

======
- Fix keygen

0.10.1

======
- Preserve attributes on install.

0.10.0

======
- Include a copy of pkg_resources. Wheel can now install into a virtualenv
that does not have distribute (though most packages still require
pkg_resources to actually work; wheel install distribute)
- Define a new setup.cfg section [wheel]. universal=1 will
apply the py2.py3-none-any tag for pure python wheels.

0.9.7

=====
- Only import dirspec when needed. dirspec is only needed to find the
configuration for keygen/signing operations.

0.9.6

=====
- requires-dist from setup.cfg overwrites any requirements from setup.py
Care must be taken that the requirements are the same in both cases,
or just always install from wheel.
- drop dirspec requirement on win32
- improved command line utility, adds 'wheel convert [egg or wininst]' to
convert legacy binary formats to wheel

0.9.5

=====
- Wheel's own wheel file can be executed by Python, and can install itself:
``python wheel-0.9.5-py27-none-any/wheel install ...``
- Use argparse; basic ``wheel install`` command should run with only stdlib
dependencies.
- Allow requires_dist in setup.cfg's [metadata] section. In addition to
dependencies in setup.py, but will only be interpreted when installing
from wheel, not from sdist. Can be qualified with environment markers.

0.9.4

=====
- Fix wheel.signatures in sdist

0.9.3

=====
- Integrated digital signatures support without C extensions.
- Integrated "wheel install" command (single package, no dependency
resolution) including compatibility check.
- Support Python 3.3
- Use Metadata 1.3 (PEP 426)

0.9.2

=====
- Automatic signing if WHEEL_TOOL points to the wheel binary
- Even more Python 3 fixes

0.9.1

=====
- 'wheel sign' uses the keys generated by 'wheel keygen' (instead of generating
a new key at random each time)
- Python 2/3 encoding/decoding fixes
- Run tests on Python 2.6 (without signature verification)
