 Thus, approximately the 30th of November there will be a scheduled network upgrade on the Monero network. To be sufficiently prepared, a user, service, merchant, pool operator, or exchange should run CLI v0.15 or GUI v0.15. The scheduled network upgrade introduces a few major changes. First and foremost, a new long-term Proof-of-Work algorithm, namely **RandomX**, will be introduced. Miners therefore ought to upgrade their mining software as well. Second, **long payment IDs will be phased out** in order to improve privacy and user experience as well as reduce support work for services and exchanges. Third, **transactions will now require at least two outputs**. Fourth, the **ten block (approximately twenty minutes) lock time** for incoming transactions will be enforced on the protocol level. Both these changes will improve privacy for the user as well as for the whole network.
