Bugfix release.

Fixes

• Fixed packages not found for prerelease version constraints when resolving dependencies.
• Fixed init and add commands.

This version brings a brand new dependency resolver which is more consistent, reliable and faster.

New Features

Brand new dependency resolver

The dependency resolver has been rewritten from scratch to make it more resilient and reliable.

It solves conflicts in a faster and smarter way to be as exhaustive as possible.

It also comes with much clearer error messages when no valid solution can be found. Here are some examples:

Fixes

• Fixed handling of package names with dots. (Thanks to bertjwregeer)
• Fixed path dependencies being resolved from the current path instead of the pyproject.toml file. (Thanks to radix)

This version brings huge improvements to the dependency resolution speed.

New Features

Huge speed improvements in the dependency resolution process

In previous releases, the dependency resolution process could be extremely slow, especially for some packages like boto3, due to the way the resolver works.

So, one of the focus of this release was to improve it so that the dependency resolution time could be deemed acceptable. And it seems it paid off.

New Features

Support for Python 2.7

After adding support for Python 3.4 and 3.5 in version 0.7.0, poetry now supports Python 2.7.

The decision was made so that Python 2.7 projects can benefit from the advantages that poetry provides.

Fallback mechanism for missing dependencies

poetry uses the PyPI JSON API to retrieve package information.

However, some packages (like boto3 for example) have missing dependency information due to bad packaging/publishing which means that poetry won’t be able to properly resolve dependencies.
