# Release checklist
# - wait for travis build.
# adjust src/paperless/version.py
# changelog in the documentation
# adjust versions in docker/hub/*
# If docker-compose was modified: all compose files are the same.

# Steps:
# run release script "dev", push
# if it works: new tag, merge into master
# on master: make release "lastest", push
# on master: make release "version-tag", push
# publish release files
