# Builds the single-file wizard (.github/tools/bundle.sh) and publishes it as a
# release per version: tag v$VERSION (VERSION in steamify.sh),
# with that version's CHANGELOG.md section as notes. A released version is
# never overwritten; the newest one is marked latest, and the "latest" tag and
# release are moved to it, so both of these always get the newest version:
#   curl -fsSL https://github.com/theupriser/steamify-cachyos/releases/latest/download/steamify.sh | bash
#   curl -fsSL https://github.com/theupriser/steamify-cachyos/releases/download/latest/steamify.sh | bash
# Each release also has the app (v2): steamify-app.tar.gz (ui/, steamify.sh,
# lib/, the icon) and its launcher, run with:
#   curl -fsSL https://github.com/theupriser/steamify-cachyos/releases/latest/download/steamify-app.sh | bash
# Pull requests only build and check it, and warn when VERSION is already released.
