(30)In addition to contractually agreed updates, the seller should also provide updates, including security updates, in order to ensure that goods with digital elements remain in conformity. The seller's obligation should be limited to updates which are necessary for such goods to maintain their conformity with the objective and subjective requirements for conformity laid down in this Directive. Unless the parties have contractually agreed otherwise, the seller should not be obliged to provide upgraded versions of the digital content or digital service of the goods or to improve or extend the functionalities of goods beyond the conformity requirements. If an update provided by the seller, or by a third party supplying the digital content or digital service under the sales contract, causes a lack of conformity of the good with digital elements, the seller should be liable for bringing the good into conformity again. The consumer should remain free to choose whether to install the updates provided. Where the consumer decides not to install the updates which are necessary for the goods with digital elements to maintain their conformity, the consumer should however not expect such goods to remain in conformity. The seller should inform the consumer that the consumer's decision not to install updates which are necessary for keeping the goods with digital elements in conformity, including security updates, will affect the seller's liability for conformity of those features of the goods with digital elements which the relevant updates are supposed to maintain in conformity. This Directive should not affect obligations to provide security updates laid down in other Union law or in national law.
