v0.0.13

  • %Bolty.Types.Point{} parameters are now sent as native PackStream Points instead of being silently converted to Maps. This allows Points (and arrays of Points) to be stored directly as Neo4j node properties. Breaking: callers that pass a %Bolty.Types.Point{} to Cypher's point() constructor must now pass a Map instead (or use Bolty.Types.Point.format_param/1 to convert). See https://github.com/diffo-dev/bolty/pull/35
