# A list of features and their supported microversions. Note that these are
|
|
# explicit functioning versions, not a range.
|
|
# There should be a minimum of two versions per feature. The first entry in
|
|
# this list should always be the lowest possible API microversion for a
|
|
# feature i.e. the version at which that feature was introduced. The second
|
|
# entry should be the current service version when the feature was added to
|
|
# horizon.
