# If another push to the same PR or branch happens while this workflow is still running,

# cancel the earlier run in favor of the next run.

#

# There's no point in testing an outdated version of the code. GitHub only allows

# a limited number of job runners to be active at the same time, so it's better to cancel

# pointless jobs early so that more useful jobs can run sooner.
