Quick one, where's the code using the DEPRECATIONS array?

It's here:

travis-build/lib/travis/build/script.rb

Lines 445 to 456 in a8d57ff

	def check_deprecation
	return unless self.class.const_defined?("DEPRECATIONS")
	self.class.const_get("DEPRECATIONS").each do |cfg|
	if data.language_default_p && DateTime.now < Date.parse(cfg[:cutoff_date])
	sh.echo "Using the default #{cfg[:name] || self.class.name} version #{cfg[:current_default]}. " \
	"Starting on #{cfg[:cutoff_date]} the default will change to #{cfg[:new_default]}. " \
	"If you wish to keep using this version beyond this date, " \
	"please explicitly set the #{cfg[:name]} value in configuration.",
