Important: This release fixes a critical issue that prevented hashes from being retrieved when locking dependencies, due to a breaking change on PyPI JSON API (see #5972 and the upstream change for more details).

After upgrading, you have to clear Poetry cache manually to get that feature working correctly again:

$ poetry cache clear pypi --all
