# mypy: disallow-untyped-defs
"""
Script used to generate a Markdown file containing only the changelog entries of a specific pytest release, which
is then published as a GitHub Release during deploy (see workflows/deploy.yml).

The script requires ``pandoc`` to be previously installed in the system -- we need to convert from RST (the format of
our CHANGELOG) into Markdown (which is required by GitHub Releases).

Requires Python3.6+.
