# Rocket.Chat upgrade verification.
# ---------------------------------------------------------------------------
# Rocket.Chat runs schema migrations on boot and refuses to start when the image
# is more than one major ahead of the database — the exact failure that once
# kept this app on manual updates. Confirming the version it actually serves is
# what makes stepping it safe.
#
# /api/info is unauthenticated and reports {"version":"8.7", …}. Note it reports
# a shorter version than the tag (8.7 for tag 8.7.0); the shared comparison only
# requires agreement on the components both sides state.
