# NOTE: for the current releases table, it helps to keep continuing releases
# in the same table positions since this minimizes the patch diff for review.
# The order of the table does not matter since Toaster presents them sorted.
#
# Traditionally, the two most current releases are included in addition to the
# 'master' branch and the local installation's 'HEAD'.
# It is also policy to include all active LTS releases.
