version.yml

# version.yml — the version check of pull requests to v2 (#230, #239, #244)
#
# A change to the app or its build (android/, build.yml) comes with a new
# versionName (MAJOR.MINOR.PATCH) and its CHANGELOG.md section, unless the
# no-release label says the APKs do not change. A workflow of its own:
# adding or removing a label re-runs this check, not the build. basic keeps
# its own workflow and version file (app/build.gradle).
