Changelog

1.10.0

• --generate-hashes now generates hashes for all wheels,
  not only wheels for the currently running platform (520). Thanks jdufresne
• Added a -q/--quiet argument to the pip-sync command to reduce log output.

Bug Fixes:

• Fixed bug where unsafe packages would get pinned in generated requirements files
  when --allow-unsafe was not set. (517). Thanks dschaller
• Fixed bug where editable PyPI dependencies would have a download_dir and be exposed to git-checkout-index,
  (thus losing their VCS directory) and python setup.py egg_info fails. (385 and 538). Thanks blueyed and dfee
• Fixed bug where some primary dependencies were annotated with "via" info comments. (542). Thanks quantus
• Fixed bug where pkg-resources would be removed by pip-sync in Ubuntu. (555). Thanks cemsbr
