name: Desktop release

# Builds the desktop client for Windows, Linux and macOS, the Windows
# installer, the Linux packages and the update manifest, and keeps them as
# one workflow artifact. Publishing is up to you: put the files and
# warp-desktop.json in one directory on a web server, at the URL in the
# DESKTOP_UPDATE_URL repository variable, which the builds check for
# updates.
#
# Start it by pushing a tag desktop-v1.2.3, or by hand with a version.
# Nothing is signed yet: the Windows build shows SmartScreen's warning and
# the macOS one opens only after "Open anyway" (see apps/desktop/README.md).
