version.yml

# Creates a new version by:
# 1. bumping the version number in the changelog and cargo
# 2. Creates a new branch for this version
# 3. makes a new commit
# 4. Opens a PR for the new version
# 5. Pulls that branch and builds it for different platforms
# 6. Once all those build, makes a release
# 7. Creates a tag for that release
# 7. merges that PR when tests pass and removes the branch

# This seperates the release process from the test process, so we can still release if we need to and tests are failing
