	# A matrix proves the supported range of Go versions work. This must always
	# include the floor Go version policy of Mosn and the current Go version.
	# Mosn's floor Go version for libraries is two behind current, e.g. if Go
	# supports 1.19 and 1.20, Mosn libraries must work on 1.18, 1.19 and 1.20.
	#
	# A floor version is required to ensure Mosn can receive security patches.
	# Without one, dependencies become locked to an old version of Go, which
	# itself receives no security patch updates.
	#
	# Mosn's binary is built with Go's floor version, e.g. if Go supports 1.19
	# and 1.20, Mosn will build any downloadable executables with 1.19.
	#
	# Even if mosn works with a Go version below its supported floor, users
	# must not depend on this. Mosn and its library dependencies are free to
	# use features in the supported floor Go version at any time. This remains
	# true even if mosn library dependencies are not eagerly updated.
	#
	# Note: There are no unit tests in this project, so we run a matrix on
	# build, not test.
	strategy:
	matrix:
	go-version:
	- "1.19" # Current Go version
	- "1.18"
	- "1.17" # Floor Go version of Mosn == current - 2
