• The constructor documentation is missing the @param entry for the newly added liveliness parameter. It should be added between the durability and avoidRosNameSpaceConventions parameters to match the parameter order in the constructor signature.

  /**
   * Create a QoS.
   * @param {HistoryPolicy} [history=RMW_QOS_POLICY_HISTORY_SYSTEM_DEFAULT] - The history value.
   * @param {number} [depth=0] - The depth value.
   * @param {ReliabilityPolicy} [reliability=RMW_QOS_POLICY_RELIABILITY_SYSTEM_DEFAULT] - The reliability value.
   * @param {DurabilityPolicy} [durability=RMW_QOS_POLICY_DURABILITY_SYSTEM_DEFAULT] - The durability value.
   * @param {boolean} [avoidRosNameSpaceConventions=false] - The avoidRosNameSpaceConventions value.
