Changelog

1.8.1

• Check if a package exists if the URL is one of:

• https://pypi.python.org/pypi/
• https://upload.pypi.org/
• https://upload.pypi.io/

This helps people with https://upload.pypi.io still in their .pypirc
file.

1.8.0

• :feature:201 Switch from upload.pypi.io to upload.pypi.org.

• :feature:144 Retrieve configuration from the environment as a default.

• Repository URL will default to TWINE_REPOSITORY

• Username will default to TWINE_USERNAME

• Password will default to TWINE_PASSWORD

• :feature:166 Allow the Repository URL to be provided on the command-line
  (--repository-url) or via an environment variable
  (TWINE_REPOSITORY_URL).

• Generate SHA256 digest for all packages by default.

• :feature:171 Generate Blake2b 256 digests for packages if pyblake2
  is installed. Users can use python -m pip install twine[with-blake2]
  to have pyblake2 installed with Twine.

• Stop testing on Python 2.6. 2.6 support will be "best effort" until 2.0.0

• Warn users if they receive a 500 error when uploading to *pypi.python.org

1.7.4

• Correct a packaging error.

1.7.3

• 🐛195 Fix uploads to instances of pypiserver using
  --skip-existing. We were not properly checking the return status code
  on the response after attempting an upload.

• Do not generate traffic to Legacy PyPI unless we're uploading to it or
  uploading to Warehouse (e.g., pypi.io). This avoids the attempt to upload
  a package to the index if we can find it on Legacy PyPI already.

1.7.2

• 🐛189, 🐛191 Fix issue where we were checking the existence of
  packages even if the user didn't specify --skip-existing.

1.7.1

• 🐛187 Clint was not specified in the wheel metadata as a dependency.

1.7.0

• :feature:142 Support --cert and --client-cert command-line flags
  and config file options for feature parity with pip. This allows users to
  verify connections to servers other than PyPI (e.g., local package
  repositories) with different certificates.

• :feature:152 Add progress bar to uploads.

• :feature:162 Allow --skip-existing to work for 409 status codes.

• :feature:167 Implement retries when the CDN in front of PyPI gives us a
  5xx error.

• :feature:177 Switch Twine to upload to pypi.io instead of
  pypi.python.org.

• 🐛186 Allow passwords to have %\ s in them.

1.6.5

• 🐛155 Bump requests-toolbelt version to ensure we avoid
  ConnectionErrors

1.6.4

• 🐛145 Paths with hyphens in them break the Wheel regular expression.

• 🐛146 Exception while accessing the respository key when raising
  a redirect exception.

1.6.3

• 🐛137, 🐛140 Uploading signatures was broken due to the pull
  request that added large file support via requests-toolbelt. This
  caused a 500 error on PyPI and prevented package and signature upload in
  twine 1.6.0

1.6.2

• 🐛132 Upload signatures with packages appropriately

As part of the refactor for the 1.6.0 release, we were using the wrong
name to find the signature file.

This also uncovered a bug where if you're using twine in a situation where
* is not expanded by your shell, we might also miss uploading
signatures to PyPI. Both were fixed as part of this.

1.6.1

• 🐛130 Fix signing support for uploads

1.6.0

• :feature:106 Upload wheels first to PyPI

• :feature:104 Large file support via the requests-toolbelt

• 🐛92 Raise an exception on redirects

• :feature:97 Allow the user to specify the location of their .pypirc

• :feature:115 Add the --skip-existing flag to twine upload to
  allow users to skip releases that already exist on PyPI.

• 🐛114 Warnings triggered by pkginfo searching for PKG-INFO files
  should no longer be user visible.

• 🐛116 Work around problems with Windows when using
  :func:getpass.getpass

• 🐛111 Provide more helpful messages if .pypirc is out of date.

• :feature:8 Support registering new packages with twine register

1.5.0

• 🐛85 Display information about the version of setuptools installed

• 🐛61 Support deprecated pypirc file format

• 🐛26 Add support for uploading Windows installers

• 🐛65 Expand globs and check for existence of dists to upload

• :feature:13 Parse ~/.pypirc ourselves and use subprocess instead of the
  distutils.spawn module.
• :feature:6 Switch to a git style dispatching for the commands to enable
  simpler commands and programmatic invocation.
